摘要
2005年10月至2007年10月,用稻茎浸渍法测定12个褐飞虱种群对吡虫啉、噻嗪酮和氟虫腈的敏感性。结果表明:12个褐飞虱种群对吡虫啉均达高或极高水平抗性;除2005年南宁、韶关和阳江,2006年阳江及2007年永州5个褐飞虱种群对噻嗪酮仍处于敏感水平外,其余种群处于敏感性降低或达到低水平抗性;而2006年阳江褐飞虱种群对氟虫腈处于敏感性降低阶段,其余的8个种群均达到了低或中等水平抗性。
Insecticide susceptibility of twelve populations of the brown planthopper (BPH), Nilaparvata lugens (Still) to imidacloprid, buprofezin and fipronil was monitored by rice-stem dipping method from October 2005 to Oetober 2007. The monitoring results indicated that the 12 brown planthopper populations had got strong or very strong resistance level to imidacloprid. In addition to 5 brown planthopper populations collected from Nanning, Sha oguan and Yangjiang in 2005, Yangjiang in 2006 and Yongzhou in 2007 that were still sensitive to buprofezin, the re maining 7 populations became susceptible or had low resistance level. In addition to the brown planthopper population collected from Yangjiang in 2006 that was susceptible to fipronil, the remaining 8 populations had low or medi um resistance level.
