The eggs are laid in batches, each female laying several hundred. Female hoverflies lay several thousand eggs. The adults feed on pollen and nectar but the larvae feed voraciously on aphids; Eupeodes corollae adjusts the number of eggs laid to the size of the aphid colony. [91]
Stalked eggs of unknown species, Mainzer Sand (Rhineland-Palatinate, Germany) Larva of a species in the Chrysoperla carnea group feeding on an aphid. 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 ...
Females deposit 100-250 tiny (1 ⁄ 64 inch [0.40 mm]) shiny orange eggs singly or in small groups among aphid colonies that hatch in 2–3 days. After 3–7 days the larvae drop to the ground and burrow 3 ⁄ 4 to 1 + 1 ⁄ 2 inches (1.9 to 3.8 cm) inches into the soil to pupate. They are most effective at 68–80 °F (20–27 °C) and high ...
Aphids are small, soft-bodied, slow ... These predators include ladybugs, parasitoid wasps, and lacewing larvae. Aphids are repelled by strongly aromatic plants such as lavender, marigolds, garlic ...
Thus, aphids show very complex and rapidly changing within-year dynamics, with each clone going through several generations during the vegetative season and being made up of many individuals, which can be widely scattered in space. The survival of the eggs and/or overwintering aphids determines the numbers of aphids present the following spring ...
When the eggs hatch, the wasp larvae feed on the inside of the aphid. As the larvae mature, the hosts die and become slightly enlarged or mummified, often becoming tan or yellow. Complete metamorphosis occurs within the host. The adult parasite chews the sugar out of the mummy leaving a hole. The genus Aphidius includes many species that ...
Aphidiines are koinobiont endoparasitoids of adult and immature aphids. While the larva of the 2–3 mm long Praon leaves the hollowed shell of the aphid from below to pupate in a volcano-like cocoon, most other Aphidiinae pupate inside the dead aphid and break out afterwards.
Chrysoperla carnea, one of the species of common green lacewing, [1] [2] is an insect in the Chrysopidae family. Although the adults feed on nectar, pollen and aphid honeydew, the larvae are active predators and feed on aphids and other small insects.
