説明

The actual situation of agricultural chemicals used on products shipped to a farmers' market in Kyoto Prefecture was investigated. Of the product investigated, the products not used agricultural chemicals was 71.7%, while products of 24.5% used insecticide. The insecticides used were primarily organophosphorus and neonicotinoid compounds.<br> Insect pests and their natural enemies were investigated in two cucumber and two eggplant fields that shipped to the farmer's market. In the cucumber fields, species of aphid and thrips pests were found, while six species (Orius spp. and arachnid.) were observed. In the eggplant fields, insect pests included species of aphid, thrips, spider mite, and larvae of the twenty-eight-spotted ladybird. Four to five species (Orius spp. and arachnid.) constituted the natural enemies.<br> The developmental patterns of insect pest species and the populations of their natural enemies may change with the weather, the kind of crops currently grown, and the environment around the edges of the fields.<br>
