Spider mite. Coloured scanning electron micrograph (SEM) of a spider mite (Tetranychus sp.). It is an economic pest and plant parasite,found on vegetable crops,fruit trees and flowers. It feeds on the leaf sap,which causes leaves to mottle,turn yellow and fall off. The spider mite is named due to its ability to spin a web,which it does across a leaf surface that secures and protects it against predators. Their numbers can be controlled with organophosphorus pesticide,although some resistance has developed. Another method is biological control,using a natural predator,such as gall midge larva (Feltiella acarisuga). Magnification: x135 at 6x7cm size | |
