9 sie 2022 · For anyone looking for natural alternatives to using insecticides, bugs that eat aphids are an absolute gift! This article discusses some of the best little pest control agents in the insect world. Aphids are insects that feed on sap, draining plants of nutrients and introducing their toxic saliva.
Insects that attack aphids include the adults and larvae of predatory ladybirds, hoverfly larvae, parasitic wasps, aphid midge larvae, "aphid lions" (the larvae of green lacewings), and arachnids such as spiders.
Minute pirate bugs (Anthocoridae) – the tiny, distinctively patterned black and white adults and the pinkish-yellow to light brown nymphs and adults are very active and will feed on small aphids. Parasitic wasps (Braconidae, Aphelinidae) – most of these wasps have similar developmental processes.
Most plants can be fed on by sap sucking greenfly, blackfly or other aphids. Aphids however, are food for many predatory insects and part of a balanced garden ecosystem. Some of these predators can be purchased as biological controls for aphids on greenhouse plants.
Aphids are soft-bodied insects that use their piercing sucking mouthparts to feed on plant sap. They usually occur in colonies on the undersides of tender terminal growth. Heavily-infested leaves can wilt or turn yellow because of excessive sap removal.
Insects from the families Aphidiinae (not to be confused with the aphid subfamily Aphidinae) and Aphelinus are parasites that specialize on aphids. Both of these groups inject an egg into the body of an aphid. The egg then hatches and the larva feeds upon the aphid's body from the inside out.
