抄録

The influence of formulation factors of fenvalerate microcapsules, particle size and wall thickness on insecticidal efficacy against Plutella xylostella and Spodoptera litura and fish toxicity to Olyzias latipes was studied. The insecticidal efficacy of the microcapsules was affected by parameter D/T, the ratio of mass median diameter (D) to wall thickness (T), which was considered to be related to the strength of microcapsules. The fish toxicity of the microcapsules was affected by parameter D·T, the multiplication of D and T, which was considered to be related to the release rate of fenvalerate encapsulated in microcapsules. These results suggest that a very important factor to prepare excellent microcapsules for agricultural use with high insecticidal efficacy and low fish toxicity is to control parameters D/T and D·T.
