| Spider Mites |
 Spider mites are a pest in many crops. Their great reproductive capacity enables them to cause enormous damage in a short period of time. In many protected crops the two spotted spider mite Tetranychus urticae is the most important pest. In field crops, other Tetranychus species can also cause damage.BiologyThe spider mite goes through five stages, namely egg, larva, first nymphal stage (protonymph), second nymphal stage (deutonymph) and adult. All stages can be observed in the crop. SymptomsSpider mite larvae, nymphs and adults feed on the underside of the leaves and cause yellow spots, later even yellow leaves. This results in decreased plant growth and production. Finally the crop may die from the infestation. SolutionsSPIDEX - Phytoseiulus persimilis |
