Laboratory experiments on the side-effects on predatory mites (Acari: Phytoseiidae) of insecticides used in vineyards

Chemical and Biological control are parts of Integrated Pest management (IPM) that is not only utilize beneficial microbiology but also beneficial insect also known as predatory mites. Predatory mites from Phytoseiidae family such as: Typhlodromus pyri and Kampimodromus aberrans hunt pest. Moreover, sustainable use of chemical to manage pest is under European Union target due to the effect on pest and bioaccumulation, as well as side effect to predatory mites including mortality, toxicity, and fecundity. However, the effect of latest brand of five different pesticides yet to be discovered. This study aims to determine the effect of five different pesticides on Typhlodromus pyri. A laboratory experiment conducted. Samples lived on the upper side of grapevine leaf. Thorough observation regarding the number of female survival, eggs, and young mites, especially after the third day and the seventh day of pesticide application. This study used one way ANOVA to determine the effect on the survival of Typhlodromus pyri after the pesticide application. Furthermore, ANOVA one way show higher value of F statistic compare to F table which means high significance difference, thus low survival of Typhlodromus pyri after Deltamethrin application
