Apihds

Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids.

Some questions are asked:

Q. Are aphids harmful?

Ans. DAMAGE. Low to moderate numbers of leaf-feeding aphids aren't usually damaging in gardens or on trees. 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.

Q. What causes aphids?

Ans. Aphids become more of a problem when things get out of whack, which can happen when plants are stressed by drought, poor soil conditions, or overcrowding.
