Slow resistance evolution to neonicotinoids in field populations of wheat aphids revealed by insecticide resistance monitoring in China

Abstract

BACKGROUND The wheat aphids, Rhopalosiphum padi and Sitobion miscanthi, are serious agricultural insect pests of many crops. Neonicotinoid insecticides are commonly used as alternatives to organophosphate and pyrethroid insecticides for controlling wheat aphids. RESULTS Long‐term monitoring of resistance to imidacloprid and acetamiprid in R. padi and S. miscanthi was carried out between 2007 and 2019. For this study, 344 specimens of the two wheat aphids were collected from field populations found in the main wheat production areas in China, from 2007 to 2019. In R. padi, the fluctuation in resistance was 14.7 times for imidacloprid and 1.4 times for acetamiprid; in S. miscanthi, it was 9.7 times for imidacloprid and 6.5 times for acetamiprid. CONCLUSION Our results demonstrated that both R. padi and S. miscanthi tended to have higher resistance to imidacloprid compared with acetamiprid. However, it is difficult for wheat aphids to develop a high level of neonicotinoid resistance given the pest control practices used in China. These results should be useful for the biorational application and resistance management of neonicotinoid insecticides. © 2021 Society of Chemical Industry.

The effects of acetamiprid multigeneration stress on metabolism and physiology of Aphis glycines Matsumura (Hemiptera: Aphididae)

“…Low or sublethal doses of insecticides induce the accumulation of resistance to soybean aphids over multiple generations. Insecticides with different modes of action should be applied in rotation in agricultural production to avoid the continuous selection of a single resistance mechanism (Xu et al, 2021). In addition, LC 50 values of relatively sensitive soybean aphid of F0 generation cultured in the laboratory for many years in this study could be used as a reference for establishing a sensitive baseline.…”

“…They affect the central nervous system of insect pests, causing abnormally excited, spasmodic, paralyzed, and eventually, the insect dies (Taillebois et al, 2018). The neonicotinoids have quickly occupied the market because of their excellent efficacy on target pests and minimal toxicity to mammals (Shao et al, 2013; Xu et al, 2021). Among neonicotinoids, acetamiprid is widely used to control A. glycines on soybean, cotton, tobacco, and other crops (Aseperi et al, 2020; Lu et al, 2021; Mokbel, 2019).…”

Emulsifiable oil‐formulated Beauveria bassiana competes with imidacloprid for seasonal control of cereal aphids in Zhejiang, China

“…Outbreaks of cereal aphid populations at the elongation through milk ripening stages cause tremendous damage by sucking plant sap, transmitting viral diseases, and reducing photosynthesis of the leaves where excreted honeydew facilitates mold growth. 1,2 The control of cereal aphids has long relied upon chemical insecticides applied by prophylactic sprays 3,4 or seed treatments. [5][6][7] The widespread chemical application has resulted in the development of aphid resistance to main types of insecticides, primarily pyrethroids and neonicotinoids, 3,4 and accelerated the pest resurgence, 2 making it necessary to develop alternative strategies for sustainable control of cereal aphids.…”

“…However, due to indiscriminate chemical applications, aphids have developed different levels of insecticide resistance worldwide. 4,11 Indeed, prophylactic application of neonicotinoids, which are water-soluble and prone to leaching into waterways, have accumulated in soils, waterways, field margin plants and floral resources at the concentrations as applied for pest control or above LC 50 s towards beneficial pollinators or non-target aquatic invertebrates. 12 In Europe, effective control of cereal aphids by pyrethroids and neonicotinoids suppressed the prevalence of yellow dwarf disease in the past decades.…”
