We previously reported that two parasitic wasps, Anagyrus sawadai Ishii and Leptomastix dactylopii Howard, are strongly attracted to (2,4,4-trimethyl-2-cyclohexenyl)methyl butyrate (cyclolavandulyl butyrate, CLB), a cyclization product of the sex pheromone of the Japanese mealybug, Planococcus kraunhiae (Kuwana). These wasps attacked more P. kraunhiae in the presence of CLB in our field experiments. In the present study, we showed that these CLB-attracted wasps parasitized and suppressed the mealybug population increase in field persimmon orchards, which would lead to reducing mealybug damage on commercial products. Although many attractants for natural enemies are reported, compounds such as CLB that suppress pest population growth in fields are scarce. Moreover, to the best of our knowledge, this is currently the only example to demonstrate that the “non-natural” enemy that does not typically attack the pest under natural conditions can be enrolled in biological control by using its attractant.
