Abstract

Impact of Permethrin-Insecticide Application on Mirid Pest of Cocoa Helopekis spp. (Ilemiptera: Miridae) and on Non-target Arthropods in Cocoa Plantations (Theobroma cacao L.). Cocoa mirid bugs, Helopeltis spp., (Hemiptera. Miridaefare the most important pest of cocoa in Indonesia. A field study was conducted to investigate the effect of permethrin on cocoa mirids and non-target arthropods at a cocoa plantation in specific place. A randomized complete block design was used in which each of four blocks consisted of 5 treatments (4 concentrations of permethrin; 50; 100, 200; andZSO ppm and control). The results indicated that the application of permethrin significantly increased the cocoa mirids mortaliiy throughout all sprayed cocoa trees (up to 100% 72 h after application). Even at I h after application, the percentage of Cocoa mirids mortality Qg.z% - 53.9%) on cocoa trees sprayed with permethrin at concentrations of 50 - ZSO ppm was significantly higher than that on control plant (3.6%). At72 h after treatments, application of permethrin at concentrations of ZOO and ZSO ppm caused a complete kill (mortalty of 100%) in the test mirids. Meanwhile, ground cloths caught at least 22 fanilies of abore-ground arthropods that were found killed by permethrin applications. Moreover, the ,u.ib". ofnon-target arthropods killed by permethrin at concentrations of 100 - 250 ppm (27.3 - 85.3 individuals/ground cloth) were signiircantly higher than that on control trees. These results demonstrated that despite high efficacy of permethrin in controlling of cocoa mirids (Hetopettis spp.), its application also had adverse effects on non-target arthropods
