Effect of Insecticides on the Adaptability of Brown Planthopper on Rice Varieties

Brown planthopper (BPH) is a major pest on rice in Indonesia. Control technique commonly uses resistant rice varieties and insecticide applications. BPH insects rapidly adapt to the longterm planted varieties and to frequently applied insecticides. The aim of this research was to study the effect of three insecticides on BPH adaptation on three resistant rice varieties. The study was conducted at the Indonesian Center for Rice Research, from December 2018 to August 2019. BPH insects were collected from farmers’ fields and reared for 6 generations, separately. The BPHs were then divided into four populations. Each population was sprayed in each generation with BPMC (BPMC-BPH), imidacloprid (imidacloprid-BPH), pymetrozine (pymetrozine-BPH), and unsprayed (Control-BPH). In the first generation, insecticide resistance test was conducted to obtain baseline data for BPH resistant to imidacloprid, BPMC and pymetrozine. In the 6 generation, the insecticide resistance test was repeated to each population. Four BPH populations were each tested for their survival rate, fecundity, production of honeydew, and reaction to rice varieties. Results showed that the 1 generation of Karawang BPH population was resistant to BPMC and imidacloprid with the Resistance Ratios (RR) of 4.1 and 13.5 folds, respectively. Resistant to pymetrozine insecticide was indicated by RR of 3.7 folds. In the 6 generation, the LC50 of all BPH population increased, while on the Control-BPH, it was decreased. Inpari 13 variety is still effective against BPH in all test. Insecticide resistance-BPH tends to have a lower adaptation on resistant variety than that of the insecticide susceptible-BPH on their survival and varietal reaction. Resistant varieties should be planted to suppress the insecticide resistance-BPH attack.
