Abstract

This survey was performed to elucidate whether pesticide can cause the non-spinning syndrome of silkworm, Bombyx mori in Yecheon and Sangju 2002. We primarily focused to Insect Growth Regulator Pesticides(IGR) used in that areas. In the result of the survey to the retail pesticide store at Yecheon and Sangju, seven pesticides of the total 12 IGR pesticides sold were used during spring sericuitural season. 7 pesticides might effect on silkworm in consideration of possibility of exposure according to the characteristics of used amount, spray drift, volatility and treatment time. Five chitin synthesis inhibitor involving diflubenzuron of 7 IGR pesticides were known as very toxic to silkwork after exposure by skin and feeding but no non-spinning syndrome was observed from several papers. Methoxyfenozide and tebufenozide also has used at sericultural season, but are ecdysone agonist. One of the most feasible suspect of non IGR pesticide, was molinate in consideration of its volatility property and wide spread use in the sericultural area. But it's symptom after exposure of molinate was not the same as the non-spinning syndrome broke out at the sericultural farm in Yecheon and Sangju.
