Buprofezin susceptibility survey, resistance selection and preliminary determination of the resistance mechanism in Nilaparvata lugens (Homoptera: Delphacidae)

Abstract

The results from this study indicate that N. lugens has the potential to develop high resistance to buprofezin. A resistance management program with rotation of buprofezin and other pesticides may efficiently delay or slow down resistance development in the insect. Further investigation is also necessary to understand the resistance mechanisms in N. lugens.

Status of Insecticide Resistance of the Whitebacked Planthopper,Sogatella furcifera(Hemiptera: Delphacidae)

“…A similar scenario of buprofezin resistance was also presented by N. lugens (Lin et al 2011). In 2006 and 2007 the buprofezin susceptibilities of WBPH were assayed in our laboratory, and no resistance was observed at that time; thus the resistance must have evolved in the most recent 4 yr. No resistance to buprofezin was recorded in the BPH before 2004 (Wang et al 2008b), however in 2010 high levels of resistance to this chemical were detected in most rice growing areas of China and Vietnam (Lin et al 2011). The flare up of resistance to buprofezin by WBPH and BPH may be caused by its increased application in rice fields as a result of the development of extremely high resistance to imidacloprid by BPH since 2005 (Gorman et al 2008;Wang et al 2008a).…”

“…Thus the stem dipping method may be superior to topical application for analyzing the dose-response of pymetrozine. Similarly, the stem dipping method was suitable for any insecticides with stomach toxicity, such as buprofezin (Wang et al 2008b). In 2009, the China Ministry of Agriculture issued an industrial standard for monitoring rice planthopper resistance to insecticide (Lin et al 2011), and recently the stem dipping method was adopted for monitoring of planthopper resistance to insecticides (Wang et al 2008a(Wang et al , 2009Ling et al 2009).…”

Synergistic and compensatory effects of two point mutations conferring target-site resistance to fipronil in the insect GABA receptor RDL

“…Bioassay and resistance selection were performed using the rice-stem dipping method with third instar nymph52. Fipronil was dissolved into acetone and then diluted into six concentrations with water.…”

Point mutations in acetylcholinesterase 1 associated with chlorpyrifos resistance in the brown planthopper, Nilaparvata lugens Stål

“…The brown planthopper (BPH), Nilaparvata lugens, is a major insect pest of rice crops throughout Asia, with direct and indirect deleterious effects such as reducing plant growth, wilting and leaf chlorosis (Gorman et al, 2008). In addition to direct sucking, oviposition and virus disease transmission by N. lugens result in more severe damage to rice plants (Wang et al, 2008). Chemical control has thus far been the primary strategy used to manage N. lugens; however, N. lugens has developed resistance towards many kinds of insecticides.…”

“…For example, high or super-high resistance to imidacloprid has been detected in both lab-selected strains and field populations (Liu et al, 2005;Wen et al, 2009;Zhang et al, 2014;Garrood et al, 2016). Given the high levels and geographical distribution of imidacloprid resistance in fields since 2006, imidacloprid application has dramatically reduced and is not recommended for wide use in controlling N. lugens in China (Wang et al, 2008;Wen et al, 2009). Pymetrozine, an azomethine pyridine insecticide, has been commonly used for N. lugens control in China recently.…”
