They are predatory insects, feeding on small insects including aphids and red spider mites. [1] A. nemorum lays its eggs inside plant leaves. [7] It has been used as a biological pest control since 1992, primarily to control Cacopsylla pyri. [8] It is capable of biting humans. [9]
Calliphoridae are, alongside managed and wild bees, likely to be the main crop pollinating insect. They visit (and thus may pollinate) flowers of a wide range of plants, including crop plants (e.g. avocado, mango, onion, leek, carrot, cauliflower). Their sponging mouthparts mean that when visiting flowers, their head and upper body must broadly ...
What they look like: Chiggers, a type of small mite, typically leave clusters of bites that are often very itchy. In many cases, chigger bites appear as small, red and itchy bumps. Sometimes, they ...
Eggs are deposited at night, singly or in small groups; one female produces some 100–200 eggs. Eggs are placed on plants, usually where aphids are present nearby in numbers. Each egg is hung on a slender stalk about 1 cm long, usually on the underside of a leaf. Immediately after hatching, the larvae moult, then
More than 100 insect species prey on H. zea, usually feeding on eggs and larvae. [24] The insidious flower bug (Orius insidiosus), a pirate bug, feeds on the eggs of H. zea, thus acting as a biological control agent. [24] Some plants emit a blend of chemicals in response to damage from H. zea, which attract parasitic insects. [25]
[31] [50] [67] The female uses its ovipositor to drill into plant material to lay her eggs (though the family Orussoidea lay their eggs in other insects). Plant-eating sawflies most commonly are associated with leafy material but some specialize on wood, and the ovipositors of these species (such as the family Siricidae) are specially adapted ...
While the layout of internal genital ducts and openings of the female genitalia depends upon the taxonomic group that insect belongs to, the internal female reproductive system of all lepidopterans consists of paired ovaries and accessory glands which produce the yolks and shells of the eggs. Female insects have a system of receptacles and ...
A cecidomyiid laying eggs on grass Cecidomyiid in copula Cecidomyiid oviposting into boreholes of bark beetles on a fallen beech. Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are ...
