Description

<p>The relationships between the timing of initial bud and fruit infestation by first-instar larvae of the persimmon fruit moth, Stathmopoda masinissa Meyrick, the day of full bloom of the cultivar ‘Fuyu’ and first catch dates of overwintering-generation adult males in pheromone traps were investigated in persimmon orchards in Gifu, Hiroshima, and Shimane Prefectures, Japan, between 2010 and 2013. Ten days after the day of full bloom of ‘Fuyu’ coincided with the period between initial bud infestation and initial fruit infestation of S. masinissa, and insecticide spraying at this time was effective in suppressing fruit damage caused by this pest. Twenty days after the first trap catch of the overwintering-generation of S. masinissa coincided with the period between initial bud infestation and initial fruit infestation. Thus, to control this pest, we recommended insecticide spraying at 10 days after full bloom of ‘Fuyu’ or at 20 days after the first trap catch of the overwintering-generation of S. masinissa.</p>
