Green peach aphid



Scientific Name

Myzus persicae




The insect Myzus persicae is also known as the Green Peach Aphid and commonly infests crops such as coles, peppers and some species of fruit trees. The green peach aphid will hinder the growth of the plants and reduce yields by feeding on plant tissues. They do so by inserting their mouth parts (stylet) through the leaf tissue into the phloem of the host. The aphid tends to feed on the newer leaves available, thus affecting the growing points of the plant. The main damage caused by green peach aphids is the spread of diseases, especially plant viruses. There are over 100 documented diseases that the green peach aphid can spread, for which its adequate control and management is critical to for the productivity of the crops.

Main description

The aphid nymphs appear very similar to the un-winged adults, with a yellowish green pear shaped body, black legs and antennae. The winged form has a much slimmer body with clear, oval-shaped wings.


Aphid population levels are heavily influenced by temperature, rainfall, numbers of natural enemies present, and pesticide application. Aphid outbreaks are most frequent in hot, dry weather, while heavy rains will often reduce the aphid population below the economic threshold.
