Baseline Susceptibility of Brown Planthopper, Nilaparvatalugens (Stål) to Mesoionic Insecticide Triflumezopyrim of Some Rice Areas in West and Central Java of Indonesia
Journal Title: Scholars Journal of Agriculture and Veterinary Sciences - Year 2017, Vol 4, Issue 12
Abstract
Abstract:Issues inability of neonicotinoid and others insecticides to control of brown planthopper (BPH), Nilaparvatalugens(Stål) was suspected due to BPH had beenresistant to those insecticides. To response this issues was carried out the research to evaluate rice BPH from 6 districts of West and Central Java against mesoionictriflumezopyrim (TFM) and neonicotinoidimidacloprid (IMI). The research used topical application method with probit analysis by POLO-PC. The result showed that the probits analysis of BPH to TFM and IMI were accepted to determined LD50, fiducial limit, and accurate for making probitregression model base on natural response, t-ratio, g-value and heterogeneity. Responce BPH from Subang was highly susceptible category to TFM with LD50 was 0.103 ng/gbody weight and resistance ratio (RRcalculate) was 0.15-fold.BPH from Indramayu, Klaten, and Pati tend to decreased susceptibility to TFMwith LD50were 1.46-1.840 ng/g body weight andRRcalculatewere 2.15-2.70-fold. BPH from Pemalang was decreased susceptibility category to TFM with LD50 was 2.687 ng/g body weight with RRcalculate was 3.95-fold. BPH from Karawang was low resistance category to TFM withLD50 was 3.730 ng/g andRRcalculatewas 5.48 fold. BPH from Indramayu and Pemalang were highly susceptible to IMI with the LD50 were 91.450 and 101.346 ng/g body weight, whereas the RRcalculatewere 0.83 and 0.92-foldrespectively. BPH from Karawang, Subang, and Klaten tend to susceptible category to IMI with LD50 were 149.293-195.638 ng/g body weight and RRcalculate were 1.35-1.77-fold. BPH from Pati tend to decreased susceptibility to IMI with LD50 was 313.243 ng/g body weight and RRcalculate was 2.84-fold. TFM providea lowLD50andthis insecticidecan be used as complementary insecticide in the field and tosolvethe problem BPH that had been resistant tootherinsecticidesby a sequential release method in IPM strategies.
