Life History -In the Southeast, melon aphids may spend part of the winter as wingless adults in soil or field debris. During warm periods, they travel to weedy hosts and continue feeding until cold weather forces them back into hibernation. In spring, winged females fly to suitable host plants and give birth to living young. Each female produces an average of 84 nymphs. Under favorable conditions, a nymph will mature in about 5 days and begin producing its own progeny.
Most nymphs develop into wingless adults.
However, when crowding occurs or food becomes scarce, winged adults develop and fly to new host plants. Reproduction continues through the winter as in the summer but at a much slower rate. Many overlapping generations are produced each year. Syrphid maggots and ladybird beetles and their larvae feed upon melon aphids. Braconid wasps parasitize the aphids, and ants feed upon the honeydew excreted by feeding aphids.
