The evolution of insecticide resistance in the brown planthopper (Nilaparvata lugens Stål) of China in the period 2012–2016

Abstract

The brown planthopper, Nilaparvata lugens, is an economically important pest on rice in Asia. Chemical control is still the most efficient primary way for rice planthopper control. However, due to the intensive use of insecticides to control this pest over many years, resistance to most of the classes of chemical insecticides has been reported. In this article, we report on the status of eight insecticides resistance in Nilaparvata lugens (Stål) collected from China over the period 2012–2016. All of the field populations collected in 2016 had developed extremely high resistance to imidacloprid, thiamethoxam, and buprofezin. Synergism tests showed that piperonyl butoxide (PBO) produced a high synergism of imidacloprid, thiamethoxam, and buprofezin effects in the three field populations, YA2016, HX2016, and YC2016. Functional studies using both double-strand RNA (dsRNA)-mediated knockdown in the expression of CYP6ER1 and transgenic expression of CYP6ER1 in Drosophila melanogaster showed that CYP6ER1 confers imidacloprid, thiamethoxam and buprofezin resistance. These results will be beneficial for effective insecticide resistance management strategies to prevent or delay the development of insecticide resistance in brown planthopper populations.

The OST‐complex as target for RNAi‐based pest control in Nilaparvata lugens

“…The overuse of conventional synthetic insecticides in the last six decades did not only have a serious detrimental effect on the environment but also resulted in the emergence of resistance to most classes of conventional insecticides (Wu et al, ). As a result, there is an urgent need to develop alternative pest control strategies which, in contrast to the synthetic pesticides, need to be specific for the pest insect, environmental friendly and sustainable.…”

“…In the last decades, pest control methods for BPH and other pest insects have relied on the use of conventional synthetic pesticides. However, the extensive use of these pesticides has significantly deteriorated the environment and has resulted in the emergence of insect resistance for most classes of chemical insecticides (Wu et al, ). Therefore there is a pressing need for alternative and sustainable solutions for pest control.…”

Comparative Analysis of the Diversity of the Microbial Communities between Non-Fertilized and Fertilized Eggs of Brown Planthopper, Nilaparvata lugens Stål

“…This insect sucks nutrients from the phloem of rice plants and transmits plant viruses, causing the characteristic stunting, wilting, and browning of crops. In recent years, BPH outbreaks have frequently occurred in China and other Asian countries and caused serious rice yield reductions and economic losses [2]. The BPH is a typical monophagous vascular feeder.…”

Synthesis of pyripyropene derivatives and their pest-control efficacy

“…Both pests have developed resistance to many kinds of insecticides. [19][20][21] Although the PP derivatives in this study were not highly active against the planthopper and thrips, the results of this study provide information on altering the insecticidal spectrum.…”
