Hosts can kill endoparasitoids by sticking haemocytes to the egg or larva in a process called encapsulation. [21] In aphids, the presence of a particular species of γ-3 Pseudomonadota makes the aphid relatively immune to their parasitoid wasps by killing many of the eggs. As the parasitoid's survival depends on its ability to evade the host's ...
Aphidius wasps are endoparasitoids of aphids. The female wasp lays eggs in an aphid. 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.
This may provide energy for the larvae before they find any aphids. Fourth-instar larvae may consume about fifty aphids per day and adults may eat about twenty. When aphids are scarce, the adults can eat honeydew, nectar and pollen or even petals and other soft parts of plants. [14] H. convergens feed on other soft-bodied insects such as scales ...

Some farming ant species gather and store the aphid eggs in their nests over the winter. In the spring, the ants carry the newly hatched aphids back to the plants. Some species of dairying ants (such as the European yellow meadow ant, Lasius flavus) [70] manage large herds of aphids that feed on roots of plants in the ant colony. Queens leaving ...
Rhopalosiphum oxyacanthae, commonly known as the apple-grass aphid (and sometimes referred to as the apple-grain aphid [2]) is a species of aphid in the phylum Arthropoda. This species is considered a pest in agriculture and has a wide distribution around the world. These aphids can be commonly found on the fruits of apples and other such ...
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.
