Minimize moisture under the benches to reduce breeding of fungus gnats there. Ample moisture favors development of fungus gnat larvae.
The adult wasp then exits the aphid body, leaving behind a hard brown shell called an aphid mummy.
In the summer, the fly life-cycle takes about two weeks: one week for the larvae to develop and one week to pupate before emerging as new adults.
Aphids are soft-bodied, pear-shaped insects about 1/16 – 3/8 inch long. They are sucking insects that form colonies, often on tender plant tissue such as newly-opened leaves, where they cause curling.
