The purpose of this invention is to provid a pest controlling composition, which uses food or food additive having high safety for human and environment, and exhibits a high controlling effect on pests such as spider mites and aphids even at low concentration. The inventors of this invention conducted researches for solving the above problems and found that a composition containing polyglycerin fatty acid esters having HLB not more than 5 and being liquid at ambient temperature among polyglycerin fatty acid esters which have been used as food additives widely, and nonion surfactant, exhibits a high pest controlling effect at low concentration, and an extremely low possibility of enhancing resistance of the pest against the composition, so as to accomplish this invention.本發明的目的是提供一種有害生物防治組成物,該有害生物防治組成物是使用對人體、環境的安全性高的食品、食品添加物,在低濃度下也對葉蟎類及蚜蟲類等有害生物能表現高度防治效果。本發明者等為了解決前述課題而精心研究的結果,發現:含有在做為食品添加物而被廣汎使用的脂肪酸聚甘油酯之中,HLB在5以下且在常溫為液體的脂肪酸聚甘油酯,與非離子界面活性劑的組成物,在低濃度下也對有害生物具有高度的防治效果,有害生物對這些組成物產生抵抗性的可能性極低,而完成本發明。本案無圖式
