Aphides

A number of species of aphis are to be met with under glass; on cyclamen, Myzus persicae (the Green Peach Aphis) and, in the last few years, Aphis gossypii (Cotton Aphis) are damaging pests.

They attack the young leaves, and can develop unnoticed at spectacular speed.

They are also liable to transmit any of over 40 viruses, including CMV and TMV.

Chemical control:

This pest can be effectively controlled by means of specific insecticides.

Biological control:

Natural predators of aphides, such as some midges and ladybirds, give satisfactory results.
