[Effects of several commercial pesticides on the survival of Thrips nigropilosus (Thysanoptera: Thripidae) infesting chrysanthemum in Okinawa Prefecture]
Japanese Journal of Applied Entomology and Zoology 58 (3), 275-279
Abstract: Recently, Thrips nigropilosus is recognized as a predominant pest on chrysanthemum in Okinawa Prefecture, southwestern Japan. Since this species has long been regarded as a minor pest of asteraceous crops, there is little information on the pesticide susceptibility of the species. In this study, we examined the insecticidal effects of 18 commercially available agrochemicals on adult females and larvae of T. nigropilosus under laboratory conditions. As a result, nine insecticides including an organophosphate, a carbamate, a synthetic pyrethroid, neonicotinoids, and others were highly effective for both adults and larvae irrespective of their origin. The mortality rates in acephate, acrinathrin, bifenthrin, and thiamethoxiam varied between the two populations tested, suggesting variation in susceptibility to these chemicals. Malathion was the only compound which was ineffective against T. nigropilosus.
