Spider mite, SEM

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

Gall midge larva

Gall midge larva head. Coloured scanning electron micrograph (SEM) of the head of the gall midge (Feltiella acarisuga) larva, which is also known as the gall gnat or gallfly. The mouthparts (centre left) are used to pierce its prey's outer surface, and then feed on its internal fluids (haemolymph). The larvae are ferocious carnivores that feed on spider mites (Tetranychus sp.), a common pest of vegetable crops, notably bean plants. As such the gall midge is used for biological pest control by organic farmers. Magnification: x125 at 6x7cm size
