Insecticide Resistance in the Brown Planthopper, Nilaparvata lugens (Stål): Mechanisms and Status in Asian Countries

The rice brown planthopper (BPH), Nilaparvata lugens (Stål) is a major insect pest of rice and their infestations occur every year in several locations in Indonesia. The use of insecticides often fails to control the BPH so their populations are still high that cause rice crops show hopperburn and the farmer loses the yields. The development of insecticide resistant in BPH population is one of the factors to contribute to the failure of insecticides control. We have detected the development of field population BPH resistance to BPMC, carbofuran, MIPC, and imidacloprid, but we do not know yet the development of resistance to other insecticides to control BPH in Indonesia. This paper will review several cases on BPH resistance to insecticides in Indonesia and other countries that include aspects of the development of resistance in the field and in the laboratory, the mechanism of resistance, inheritance of resistance, genomics of resistance, and resistance management. A policy and further study is also suggested for insecticide resistance management in Indonesia.

Effect of Insecticides to Brown Planthopper (Nilaparvata lugens Stal) Adaptation on Resistant Rice Varieties. Brown planthopper (BPH) (Hemiptera: Delpachidae) is one of major pests on rice cultivation in Indonesia. Resistant rice varieties and insecticides are commonly used by farmers in BPH management. But, BPH can rapidly adapt on long-term planted varieties and insecticide. The aim of research was to study the ability of insecticide resistance BPH in adaptation on resistant rice varieties. This study was conducted at Indonesian Center for Rice Research from October 2018 to June 2019. BPH’s were collected from farmer field and reared for 6th generation. BPH’s were divided into four insecticide population. BPH population sprayed each generation by BPMC (BPMC-BPH), imidacloprid (imidacloprid-BPH), pymetrozine (pymetrozine-BPH), and unsprayed (Control-BPH). In first generation, insecticide resistance conducted to obtain baseline data of BPH resistance to imidacloprid, BPMC and pymetrozine. On 6th generation, insecticide resistance test repeated to each population. Four BPH population were tested for the survival rate, fecundity, amount of honeydew, and rice varieties reaction. Result showed that Field population 1st generation were resistance to BPMC and imidacloprid with Resistance Factor (RF) 4.1 and 13.5-fold, respectively, while to pymetrozine was indicate resistance (RF 3.7-fold). In 6th generation, LC50 all insecticide population were increased, while in Control-BPH were decreased. Inpari 13 still effective againts BPH in all test results. Insecticide resistance-BPH tend to lower adaptation on resistant variety than insecticide susceptible-BPH.
