 note = {The effect of the optimal timing for the spraying of the diamide insecticides, flubendiamide or chlorantraniliprole, for the suppression of the first- or second-generation larvae of the persimmon fruit moth, Stathmopoda masinissa Meyrick, on the suppression of the persimmon bark borer, Euzophera batangensis Caradja was investigated in a persimmon orchard. Fruit damage caused by the first- or second- generation larvae of S. masinissa in trees that were sprayed with diamide insecticides was as low as that in control trees. There were fewer larvae of the overwintering generation of E. batangensis on persimmon branches or twigs of trees sprayed with diamide insecticides at the optimal time for suppression of the second-generation larvae of S. masinissa than on the control trees. The number of second-generation larvae of E. batangensis on persimmon branches or twigs of trees sprayed with diamide insecticides at the optimal time for suppression of the first-generation larvae of S. masinissa was as low as those on control trees. The density of the overwintering generation of E. batangensis was high, and this generation was effectively suppressed by diamide insecticides spraying; however the density of second-generation larvae of this pest was low and was considered not to require suppression by diamide insecticide spraying. Therefore, we have recommended the optimal timing of diamide insecticides spraying for the suppression of second-generation larvae of S. masinissa to control the overwintering generation of E. batangensis.

カキノヘタムシガの防除適期に散布するジアミド剤のフタモンマダラメイガに対する同時防除効果を調査した．カキノヘタムシガ第 1，2 世代幼虫の防除適期におけるジアミド剤の散布は，本害虫による果実被害を対照のフェニトロチオン水和剤と同等に抑えることができた．カキノヘタムシガ第 1 世代幼虫の防除適期に散布したフルベンジアミド水和剤のフタモンマダラメイガに対する同時防除効果は，無防除区においてもフタモンマダラメイガ第 2 世代幼虫の密度が低く推移することからその有効性を評価できなかった．その一方で，カキノヘタムシガ第 2 世代幼虫に対する 2 種ジアミド剤の散布は，フタモンマダラメイガ越冬世代（第 3  世代）幼虫の密度抑制に有効であった．フタモンマダラメイガの越冬世代幼虫は密度が高いために防除の必要性が高いが，第 1，2 世代幼虫は密度が低いことから防除の必要はないと考えられた．以上から，フタモンマダラメイガの被害抑制は，カキノヘタムシガ第 2 世代幼虫防除時期のジアミド剤散布で可能と考えられた.},
