Oligonychus Pratensis
''Oligonychus pratensis'', the Banks grass mite, is a species of mite in the spider mite family. They are considered a Pest (organism), pest and often infest Maize, corn and turf grasses. Description Adult Banks grass mites range from green to brown in colour and are approximately 1/32 of an inch (~0.79 mm) in length. On either side of the body is a row of brown/reddish-brown spots, the number and position of which can be used to distinguish ''O. pratensis'' from the related two-spotted spider mite (''Tetranychus urticae''). This species can be distinguished from other ''Oligonychus'' by features such as the pattern of striation on the body, the Seta, setae on the legs and the shape of the male genitalia. Life cycle The life cycle of Banks grass mite comprises the stages: egg, larva, protonymph, deutonymph and adult. Eggs are laid on the underside of leaves and (in spring and summer conditions) hatch 3-10 days later. The mites develop rapidly, with one generation potential ...

Overwintering
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not necessarily by cold but by dry conditions; passing through such periods could likewise be called overwintering. Hibernation and migration are the two major ways in which overwintering is accomplished. Animals may also go into a state of reduced physiological activity known as torpor. Overwintering occurs in several classes of lifeform. Insects In entomology, overwintering is how an insect passes the winter season. Many insects overwinter as adults, pupae, or eggs. This can be done inside buildings, under tree bark, or beneath fallen leaves or other plant matter on the ground, among other places. All such overwintering sites shield the insect fr ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Orius Insidiosus
''Orius insidiosus'', common name the insidious flower bug, is a species of minute pirate bug, a predatory insect in the order Hemiptera (the true bugs). They are considered beneficial, as they feed on small pest arthropods and their eggs. They are mass-reared for use in the biological control of thrips. Description ''Orius insidiosus'' adults are approximately 3 mm in length. This oval-shaped insect is black with white patches on the wings. Nymphs of this species are teardrop-shaped and wingless. They range from yellow-orange to brown in colour. Distribution This species is common throughout the United States, and extends into Canada, Mexico, Central and South America. It also occurs in Cuba, Puerto Rico, and other islands of the West Indies. Life cycle The female lays her eggs inside plant tissues, where they hatch into nymphs. Growth time from egg to mature adult takes at least 20 days. It is possible for several generations to occur during a single growing season. Di ...

Hippodamia Convergens
''Hippodamia convergens'', commonly known as the convergent lady beetle, is one of the most common lady beetles in North America and is found throughout the continent. Aphids form their main diet and they are used for the biological control of these pests. Range Convergent lady beetles are native to North America, but have also been imported and established in South America by importing beetles from California. Life cycle The female lady beetle lays 200 to 300 eggs over several months during spring and early summer. The eggs are small and spindle-shaped and are laid near the prey in upright batches of fifteen to thirty eggs. The larvae are dark and somewhat alligator-shaped. Once the larvae begin feeding, they grow quickly and molt four times over a period of up to a month. The pupal stage lasts about a week and mating takes place soon after adult eclosion. If the food supply is abundant, the female may start laying within about a week of mating, but if it is scarce, she may wai ...

Phytoseiidae
The Phytoseiidae are a family of mites which feed on thrips and other mite species. They are often used as a biological control agent for managing mite pests. Because of their usefulness as biological control agents, interest in Phytoseiidae has steadily increased over the past century. Public awareness of the biological control potential of invertebrates has been growing, though mainly in the US and Europe. In 1950, there were 34 known species. Today, there are 2,731 documented species organized in 90 genera and three subfamilies. Subfamilies The family Phytoseiidae contains these subfamilies: * Amblyseiinae Muma, 1961 * Phytoseiinae Berlese, 1916 * Typhlodrominae Scheuten, 1857 Anatomy and life cycle Phytoseiid eggs can be found along the vein of the bottom side of a leaf; They are oblong and translucent white. The larvae of these mites range from translucent white to tan in colour. They are tiny and oval in shape and size, have six legs, and are wingless. Nymphs look simil ...
