Some species are predatory, but most of them feed on pollen and the chloroplasts harvested from the outer layer of plant epidermal and mesophyll cells. They prefer tender parts of the plant, such as buds, flowers and new leaves. [38] [39] Besides feeding on plant tissues, the common blossom thrips feeds on pollen grains and on the eggs of mites ...
[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 ...
Unlike some insects, the spotted lanternfly does not pose direct danger to humans through biting or stinging. [4] Spotted lanternflies lay egg masses containing 30–50 eggs, often covered with a grayish mud-like coating. [6] The species was introduced into South Korea in 2006 and Japan in 2009, and has since been considered a pest.
Trichogramma is a genus of minute polyphagous wasps that are endoparasitoids of insect eggs. [1] Trichogramma is one of around 80 genera from the family Trichogrammatidae, with over 200 species worldwide. [2] [3] [4]
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 ...
Caddisflies was the only group of these insects to use silk as part of their lifestyle, which has been a contributing factor to their success and why they are the most species-rich order of aquatic insects. [8] About 14,500 species of caddisfly in 45 families have been recognised worldwide, [9] but many more species remain to be described.
Repeated application may be necessary and the eggs could be eaten before they hatch by their natural predators, such as ants or mature green lacewings. Ladybirds are also used. They eat mostly insect eggs, but will also feed on beetle larvae, aphids, scale insects, and young caterpillars. Adults are often collected when in a dormant state in ...
All known fairyflies are parasitoids of eggs of other insects. These eggs are commonly laid in concealed locations, such as in plant tissues or underground. [12] [19] They do not seem to be species-specific when it comes to choosing hosts. Some species are known to parasitize insects from several families of a single order.
