Abstract
This study investigated the efficiency of mating disrupters for the control of Grapholita molesta(Busck) and Adoxophyes orana in pear orchards. G. molesta was shown 4 peak occurrence, which were different according to treatments. In conventional control, many moths were captured in mid and late April and peaks occurred in mid June, August, and early-mid September. In the non-control treatment, there were low populations in April. A. orana also appeared to 4 peak in 2007. Moths were rarely captured in mating disrupter treatment but many were captured in both the non-control and in conventional treatment. A. orana damage differed significantly between mating disrupter use and conventional control in 2006. Especially, the difference was significant between conventional control and mating disrupter to leaf damage in August, and there were similar results in the damage by G. molesta in the shoots and fruits.
