However, the first three species of aphids listed above are most economically damaging in Florida (Nuessly and Webb 2010). Although heavy aphid pressure can stunt plants, the major problem aphids cause is head contamination, which makes lettuce unmarketable.

- Black plastic is a good choice for northern areas, but in the extremely warm areas it can warm the soil too much. Organic mulches are good, too, but may provide shelter for pests like squash bugs. Foil mulches help prevent aphid problems. To prevent rot, support fruit on scraps of wood. Rotate crops so that no member of the cucurbit family (cucumbers, melons, and squash) is grown in the same place more often than every 4 years.

The best defense against these eggs is to clean out your flower beds and dispose of rubbish. Be sure to rake leaves and dig out any plants that may not have survived the frost. Don’t leave them in the ground or the aphid eggs will prosper.

They feed on the sap of plants and secrete a substance called honeydew. This sticky resin is a favorite food of ants, who actually “milk” the aphids for it by stroking their abdomen.

- However, large populations can turn leaves yellow and stunt shoots; aphids can also produce large quantities of a sticky exudate known as honeydew, which often turns black with the growth of a sooty mold fungus. Some aphid species inject a toxin into plants, which causes leaves to curl and further distorts growth. A few species cause gall formations. Aphids may transmit viruses from plant to plant on certain vegetable and ornamental plants. Squash, cucumber, pumpkin, melon, bean, potato, lettuce, beet, chard, and bok choy are crops that often have aphid-transmitted viruses associated with them. The viruses mottle, yellow, or curl leaves and stunt plant growth.
