Within a few days, the nymphs are mature and begin giving live birth to new female nymphs. Aphids are generally spread by females, which can grow wings when conditions are proper and fly or drift in the wind to new plant hosts. This act results in them being even more dangerous especially when they are infected with virus. Control of aphids is not particularly difficult if a few precautions are observed. It is necessary to select a recommended material for their control, but even more so, a thorough coverage of all the plant surfaces is mandatory.
Aphids prefer the undersurface of the leaves and young developing buds as feeding sites.
Thus they are protected from much of the insecticidal spray unless it is aimed at these crevices and places. Even a few females left uncontrolled can quickly lead to new populations. Several growers are experiencing problems with spider mites on eggplant, tomato, as well as melons, cucumbers and other crops. Occurrence is sporadic and damage is low to moderate in most cases. Diamondback moths are being reported in crucifers.
