Seasonal Occurrences of Orius spp. on Varieties of Okra in Kanagawa Prefecture

Abstract

Okra Abelmoschus esculentus (L.) Moench is expected to be used as an‘insectary crop’for Orius spp., which are effective natural enemies of thrips in conservation biological control (CBC). In order to obtain basic information, we investigated seasonal occurrences of Orius spp. on some varieties of okra. Orius spp. were observed on every variety of okra. The number of Orius spp. were different among varieties although the effect of their characteristics, such as fruit shape and color, was not clear.
