How to recognize cotton aphid 

The cotton aphid is a rather small (0.9-1.8 mm), round aphid with red eyes. The body color varies greatly from light yellow to light green and even almost black. This aphid species can be recognized by their short, black, tapered siphons. The cauda is small, lighter in colour than the siphons and finger shaped. The antennae are shorter than the body. The legs are short. This aphid prefers warm conditions and population growth can be very fast under suitable conditions. Cotton aphid does not change host plant during the seasonal development.

Cotton aphid damage and distribution 

In the Netherlands, this aphid only causes problems in greenhouses due to its very fast population growth at higher temperatures. The aphids prefer the underside of leaves and young shoots and leaves. The feeding can cause leaf- and shoot deformations and eventually results in early leaf drop. Like any other aphid, cotton aphids produce honeydew, which is harmful for the plant. The cotton aphid can transmit more than 50 plant viruses, making it a major pest in for example cucumber cultivation. Different population can have different characteristics regarding pesticide resistance.
