The name Manitoba possibly derives from either Cree manitou-wapow or Ojibwe manidoobaa , both meaning ' straits of Manitou , the Great Spirit ' . Alternatively, it may be from the Assiniboine minnetoba , meaning ' Lake of
285-516: A moth superfamily containing about 16,000 described species worldwide, and probably at least as many more remain to be described. They are generally fairly small moths, and as such, they have been traditionally associated with the paraphyletic Microlepidoptera . This superfamily used to contain the Hyblaeidae , Thyrididae , Alucitidae (plus Tineodidae ), Pterophoridae , and Pyralidae . The first four families are now each split off as

By 1911, Winnipeg was the third largest city in Canada, and remained so until overtaken by Vancouver in the 1920s. A boomtown, it grew quickly around the start of the 20th century, with outside investors and immigrants contributing to its success. The drop in growth in
570-551: A dark band at the intersection between the proximal and distal regions. The hindwings, in general, are uniformly gray. The eggs of the Indian-meal moth are white, ovate, and very small. It is difficult to see them with the naked eye. Newly hatched larvae are equally difficult to see. They are mostly off-white in color, have brown heads, and develop through five to seven larval instars . When these larvae mature, they measure about 12–14 millimetres ( 15 ⁄ 32 – 9 ⁄ 16 in) long. Larvae also have three sets of legs near
665-469: A delay in animal development due to certain external factors and can end once the adverse environmental conditions wear off. The duration of diapause can vary in Indian-meal moths. Diapause is especially prevalent late in the breeding season. During the egg stage, if the temperature of the moth's environment exceeds 25 °C (77 °F), it can cause a delay in hatching. In the moth's early larval stage, temperatures of below 20 °C (68 °F) can cause

The two 17 Wing squadrons based in the city are: the 402 ("City of Winnipeg" Squadron), which flies the Canadian designed and produced de Havilland Canada CT-142 Dash 8 navigation trainer in support of the 1 Canadian Forces Flight Training School's Air Combat Systems Officer and Airborne Electronic Sensor Operator training programs (which trains all Canadian Air Combat Systems Officer); and
855-944: A distinct superfamily. Nowadays, Pyralidae are usually split into the Pyralidae sensu stricto and the Crambidae , as both groups have been shown to be monophyletic and a sister group . Some genera (e.g. Micronix and Tanaobela ) still defy easy classification and have been variously assigned to the Crambidae or the Pyralidae. Among all Lepidoptera , pyraloids show the most diverse life history adaptations. The larvae of most species feed on living plants either internally or externally as leaf rollers, leaf webbers leaf miners, borers, root feeders, and seed feeders. Some species live parasitically in ant nests ( Wurthiini ), prey on scale insects (certain Phycitinae ), or live in
950-860: A grain bin must exceed 50 °F (10 °C). The eggs of the moth are grayish white and have a length between 0.3 and 0.5 millimetres ( 1 ⁄ 64 and 3 ⁄ 128 in). Eggs can be laid directly on the food source singly or in groups of between 12 and 30. A mature female may lay between 100 and 300 eggs at a time. Larvae begin to hatch in approximately two to fourteen days. The larvae have between five and seven instars . Newly hatched larvae feed on grain while more mature larvae feed on grain germ. The larvae are an off-white color, but can be pink, brown, or greenish. They are about 12 mm long and have prolegs for movement. Fully-grown larvae are able to spin webs and leave silk threads in their path of travel. Mature larvae that make silk also make threaded cocoons. The pupae are often seen on grain surfaces and on
1045-409: A limited number of sperm and allocate it depending on various factors. Male Indian-meal moths ejaculate a greater amount of sperm to females that have mated multiple times previously. This is to ensure a greater chance of success in sperm competition in the females' storage organs. Males also ejaculate more sperm when mating with a younger female. The most common type of competition in Indian-meal moths

It began on 15 May and collapsed on 25 June 1919; as the workers gradually returned to their jobs, the Central Strike Committee decided to end the movement. Government efforts to violently crush the strike, including a Royal North-West Mounted Police charge into a crowd of protesters that resulted in multiple casualties and one death, had led to
1425-567: A province in 1870, all land became the property of the federal government, with homesteads granted to settlers for farming. Transcontinental railways were constructed to simplify trade. Manitoba's economy depended mainly on farming, which persisted until drought and the Great Depression led to further diversification. CFB Winnipeg is a Canadian Forces Base at the Winnipeg International Airport. The base
1520-409: A similar diapause. Different strains of P. interpunctella have differing tendencies to enter diapause. Indian-meal moths are developing a resistance to many kinds of biological agents , such as the granulosis virus . Use of pest control agents can cause resistance to these agents to be selected for in populations of Indian-meal moths. In populations exposed to the granulosis virus, it was found that
1615-869: A steep drop in agricultural production due to drought led to economic diversification, moving away from a reliance on wheat production. The Manitoba Co-operative Commonwealth Federation , forerunner to the New Democratic Party of Manitoba (NDP), was founded in 1932. Canada entered the Second World War in 1939. Winnipeg was one of the major commands for the British Commonwealth Air Training Plan to train fighter pilots, and there were air training schools throughout Manitoba. Several Manitoba-based regiments were deployed overseas, including Princess Patricia's Canadian Light Infantry . In an effort to raise money for

This competition can change the timing of male and female emergence, reducing the chance of early males finding females to mate with, which could encourage emigration. This is considered a form of male-male competition because males that emerge at an appropriate time are more likely to be reproductively successful with the surrounding females. Males are also involved in finding pupation sites. If

Manitoba is at the centre of the Hudson Bay drainage basin, with a high volume of the water draining into Lake Winnipeg and then north down the Nelson River into Hudson Bay. This basin's rivers reach far west to the mountains, far south into the United States, and east into Ontario. Major watercourses include
5225-610: The end of French schools. In 1890, the Manitoba legislature passed a law removing funding for French Catholic schools . The French Catholic minority asked the federal government for support; however, the Orange Order and other anti-Catholic forces mobilized nationwide to oppose them. The federal Conservatives proposed remedial legislation to override Manitoba, but they were blocked by the Liberals , led by Wilfrid Laurier . Once elected Prime Minister in 1896, Laurier implemented

Even so, there is no change in postcopulatory behavior in females after this large donation (with respect to pheromone production and calling behavior). It has been observed in many insects that vital resources are tracked using odor plumes. For the Indian-meal moth these odors have other effects as well. The Indian-meal moth's fecundity and fertility was found to be enhanced in

Permanent dikes were erected in eight towns south of Winnipeg, and clay dikes and diversion dams were built in the Winnipeg area. In 1997, the " Flood of the Century " caused over C$ 400 million in damages in Manitoba, but the floodway prevented Winnipeg from flooding. In 1990, Prime Minister Brian Mulroney attempted to pass
5700-489: The food they infest. After larvae or moths have been found, it is important to throw out all food sources not in very tightly sealed containers. Moth larvae can chew through plastic bags and thin cardboard, so even unopened packages may become infested. They are also notoriously difficult to get rid of, and can crawl on ceilings and spin cocoons in rooms other than where they hatched. Last instar larvae are able to travel significant distances before they pupate . When seeking

5985-451: The larvae do not find pupation sites in the food layer, they may wander long distances to find one. This competition to find a pupation site affects males more than it does females, it indirectly impacts females as well because it results in a delayed population of males to mate with. In the Indian-meal moth, mating occurs a few days after the adult moth emerges from the silk cocoon. Mating rituals are largely limited to pheromones release by

Groundnuts and maize meal, on the other hand, result in a longer development time for the moths. Indian-meal moths are also known to cannibalize larvae. This often leads to viral granulosis infections spreading through an Indian-meal moth population. Healthy larvae are picked more often than unhealthy larvae for cannibalism. There appears to be no kin discrimination and siblings can be eaten by caterpillars. Though Indian-meal moths generally do not migrate over long distances, they do engage in long-distance foraging flights. These flights take place during
6650-416: The northern reach of its western neighbours Saskatchewan, Alberta and British Columbia . The Manitoba Schools Question showed the deep divergence of cultural values in the territory. The Catholic Franco-Manitobans had been guaranteed a state-supported separate school system in the original constitution of Manitoba, but a grassroots political movement among English Protestants from 1888 to 1890 demanded
6745-413: The pheromone blend are also known but their functions are unclear. It has been suggested the reason for having so many components to the pheromone is that it ensures species specificity. Male moths also release pheromones. After approaching the female from the back, the male releases a pheromone from wing glands located at the base of each forewing. These pheromones induce the female to remain stationary in
6840-517: The presence of the endangered western prairie fringed orchid . Manitoba is especially noted for its northern polar bear population; Churchill is commonly referred to as the "Polar Bear Capital". In the waters off the northern coast of the province are numerous marine species, including the beluga whale . Other populations of animals, including moose , white-tailed deer , mule deer , black and brown bears , coyote , cougar , red fox , Canada lynx , and grey wolf , are distributed throughout
6935-479: The presence of the odor of vital nutrients. This effect is thought to be genetic since it is not related to parental generations or previous experiences in the lifetime of the moth. Females also show a strong preference towards laying their eggs near the site of the odor. It was observed that without antennae, this effect is lost, suggesting that there are olfactory receptors in the antennae. The Indian-meal moth often takes part in interspecific courtship especially with
7030-455: The province are not dominated by forest. The province's northeast corner bordering Hudson Bay is above the treeline and considered tundra . The tallgrass prairie once dominated the south-central and southeastern regions, including the Red River Valley. Mixed grass prairie is found in the southwestern region. Agriculture has replaced much of the natural vegetation but prairie can still be found in parks and protected areas; some are notable for
7125-419: The province, especially in the provincial and national parks . There is a large population of red-sided garter snakes near Narcisse ; the overwintering dens there are seasonally home to the world's largest concentration of snakes. Manitoba's bird diversity is enhanced by its position on two major migration routes, with 392 confirmed identified species; 287 of these nesting within the province. These include
7220-474: The province. After the arrival of the first European traders in the 17th century, the economy centred on the trade of beaver pelts and other furs. Diversification of the economy came when Lord Selkirk brought the first agricultural settlers in 1811, though the triumph of the Hudson's Bay Company (HBC) over its competitors ensured the primacy of the fur trade over widespread agricultural colonization. HBC control of Rupert's Land ended in 1868; when Manitoba became
7315-622: The second half of the decade was a result of the opening of the Panama Canal in 1914, which reduced reliance on transcontinental railways for trade, as well as a decrease in immigration due to the outbreak of the First World War . Over 18,000 Manitoba residents enlisted in the first year of the war; by the end of the war, 14 Manitobans had received the Victoria Cross . During the First World War, Nellie McClung started
7410-404: The second-highest humidex ever in Canada in 2007, with 53.0. According to Environment Canada , Manitoba ranked first for clearest skies year round and ranked second for clearest skies in the summer and for the sunniest province in the winter and spring. Southern Manitoba (including the city of Winnipeg), falls into the humid continental climate zone (Köppen Dfb). This area is cold and windy in
7505-451: The source of an infestation, the search thus cannot be limited to the immediate area where pupae are discovered. Pantry moths can use clothing (remaining hidden) to reproduce and pupate, so it is important to inspect any source of clothing material. None of the stages of the organism (eggs, larvae, adults) are temperature tolerant and can be killed by a week of freezing or by brief heating in a microwave or conventional oven when such treatment
7600-475: The source of infestation followed by larvae, eggs, and eventually moths. The caterpillars are parasitized by Habrobracon hebetor , a braconid wasp which is a potential biological control agent . Additionally, blue to violet light can be very effective in drawing moths out, which suggests that the deployment of violet light could become another pest control tactic for these moths. Pyraloidea The Pyraloidea ( pyraloid moths or snout moths ) are
7695-457: The species incompatible. Their courtship behaviors are also relatively incompatible. Thus, copulation rarely occurs. Even when courtship does continue to a later stage, the female of the other species rejects the male due to the wrong pheromone being released at the wrong time from scent scales. Even with these fail safes, some male almond moths are still excited by Indian-meal moth females. They may be able to successfully copulate, but insemination
7790-584: The subsequent elected Legislative Assembly of Assiniboia on 9 March 1870. This assembly subsequently sent three delegates to Ottawa to negotiate with the Canadian government . This resulted in the Manitoba Act and that province's entry into Confederation . Prime Minister Sir John A. Macdonald introduced the Manitoba Act in the House of Commons of Canada , the bill was given Royal Assent and Manitoba
7885-420: The time was referred to as "Indian meal". Adults are 8–10 millimetres ( 5 ⁄ 16 – 13 ⁄ 32 in) in length with 16–20 millimetres ( 5 ⁄ 8 – 13 ⁄ 16 in) wingspans. The distal two thirds of their forewings are generally reddish brown in color with a copper luster. They can also be bronze or dark gray. The more proximal parts of the wings are yellow-gray or white-gray, with
7980-427: The tropical habitat. The moth lives in a wide range of conditions, making it a persistent pest . It is often found at food storage facilities worldwide, specifically in grain bins or grain storage buildings. The Indian-meal moth is the only known living species of the genus Plodia . It is closely related to the genera Cadra and Ephestia , which include other pest species like E. kuehniella , also known as
8075-408: The twilight hours during which blue light (400–475 nm) rather than UV light (10–400 nm) is dominant and attracts the moths. Blue light's role in the Indian-meal moth foraging behavior has recently been harnessed as a form of pest control since it is attractive to the moth. Usually the life cycle of an Indian-meal moth colony starts in a location where grain is present. The temperature within
8170-399: The walls of grain bins. The adults emerge in four to ten days. They then mate and the cycle begins again. The entire life cycle of this species ranges between 30 and 300 days. A typical life cycle is 50 days. Under optimal conditions a life cycle can be as short as 28 days but cooler winter months prohibit this. Seven to nine generations of moths can live in a year. Diapause is defined as
8265-474: The war effort, the Victory Loan campaign organized " If Day " in 1942. The event featured a simulated Nazi invasion and occupation of Manitoba, and eventually raised over C$ 65 million. Winnipeg was inundated during the 1950 Red River Flood and had to be partially evacuated. In that year, the Red River reached its highest level since 1861 and flooded most of the Red River Valley. The damage caused by
8360-457: The winter and often has blizzards because of the open landscape. Summers are warm with a moderate length. This region is the most humid area in the prairie provinces, with moderate precipitation. Southwestern Manitoba, though under the same climate classification as the rest of Southern Manitoba, is closer to the semi-arid interior of Palliser's Triangle . The area is drier and more prone to droughts than other parts of southern Manitoba. This area
8455-427: The world, consuming cereals , fruits , and similar products. Substantial efforts have been taken in the United States to control the moth's damage to grain crops. The larvae of this species have the ability to bite through plastic and cardboard so even sealed containers may be infested. Once found, the moths are difficult to eradicate. The last larval instar is also able to travel long distances before pupating ; so
8550-444: Was 5.8 percent. Manitoba's economy relies heavily on agriculture, tourism, electricity, oil, mining, and forestry. Agriculture is vital and is found mostly in the southern half of the province, although grain farming occurs as far north as The Pas. The most common agricultural activity is cattle husbandry, followed by assorted grains and oilseed . Manitoba is the nation's largest producer of sunflower seed and dry beans, and one of
8645-493: Was a square one-eighteenth of its current size, and was known colloquially as the "postage stamp province". Its borders were expanded in 1881, taking land from the Northwest Territories and the District of Keewatin , but Ontario claimed a large portion of the land; the disputed portion was awarded to Ontario in 1889. Manitoba grew to its current size in 1912, absorbing land from the Northwest Territories to reach 60°N, uniform with
8740-480: Was brought into Canada as a province in 1870. Louis Riel was pursued by British army officer Garnet Wolseley because of the rebellion, and Riel fled into exile. The Canadian government blocked the Métis' attempts to obtain land promised to them as part of Manitoba's entry into confederation. Facing racism from the new flood of white settlers from Ontario, large numbers of Métis moved to what would become Saskatchewan and Alberta . Numbered Treaties were signed in
8835-545: Was named for feeding on Indian meal or cornmeal, and does not occur natively in India. It is also not to be confused with the Mediterranean flour moth ( Ephestia kuehniella ), another common pest of stored grains. P. interpunctella larvae ( caterpillars ) are commonly known as waxworms . They are not the same species as the waxworms often bred as animal feed. Rather, they are a common grain-feeding pest found around
8930-409: Was one of the first Europeans to sail into what is now known as Hudson Bay, where he was abandoned by his crew. Thomas Button travelled this area in 1612 in an unsuccessful attempt to find and rescue Hudson. When the British ship Nonsuch sailed into Hudson Bay in 1668–1669, she became the first trading vessel to reach the area; that voyage led to the formation of the Hudson's Bay Company, to which
9025-561: Was originally stationed in Winnipeg (first at Fort Osborne, then in Kapyong Barracks), has operated out of CFB Shilo since 2004. CFB Shilo hosts a training unit, 3rd Canadian Division Training Centre. It serves as a base for support units of 3rd Canadian Division , also including 3 CDSG Signals Squadron, Shared Services Unit (West), 11 CF Health Services Centre, 1 Dental Unit, 1 Military Police Regiment, and an Integrated Personnel Support Centre. The base houses 1,700 soldiers. After
