Outline of Final Research Achievements

Tea leaves contain 5-8% of epigallocatechin gallate in the dry weight. It can be assumed that tea contains such abundant catechin to protect themselves from its pests. In this study, the hypothesis for tea containing catechin to protect from pests with cooperation of entomopathogen, as catechin increases susceptibility of pests against entomopathogen, were examined. Consequently, the tea pests Adoxophyes honmai (Lepidoptera: Tortricidae) increases its susceptibility against granulovirus (Baculoviridae) due to addition of EGCG with inoculum.
