摘要

2008年和2009年，在我国广西、湖南、江西及浙江等4省5地，对测报灯下褐飞虱及其两个近似种（伪褐飞虱和拟褐飞虱）的数量动态进行了研究。结果表明，灯下褐飞虱比例相对较高，2008年和2009年的比例分别为58.4%和50.5%；伪褐飞虱稍少，分别为41.5％和46.8％；拟褐飞虱最少，分别为01%和27%。总体上，前期伪褐飞虱为优势种，后期褐飞虱为优势种。但是，不同地区间褐飞虱及其近似种动态格局有明显差异，广西两地以褐飞虱为主，达60.4%~91.3%，但湖南临湘、浙江富阳以伪褐飞虱为主，达59.3%~80.7%。广西两地褐飞虱4月灯下即有发生，6月就开始处于优势地位，6-7月和10月（或10-11月）出现两个高峰；而江西万安、湖南临湘、浙江富阳5-6月份灯下才开始出现褐飞虱，至9月份才超过50％，仅在9-10月出现1个高峰。正确鉴别灯下褐飞虱种类对于改善稻飞虱预测预报有重要意义。

Abstract

Population dynamics of brown planthopper, Nilaparvata lugens, and its two siblings under black light traps were investigated in five sites of four provinces, Guangxi, Hunan, Jiangxi and Zhejiang, China during 2008-2009 and the percentage of each species under various conditions was analysed. The annual percentages of N. lugens, N. muiri and N. bakeri from the five sites were 58.4%, 41.5% and 0.1% in 2008, 50.5%, 46.8% and 2.7% in 2009, respectively. In general the dominant species was N. muiri at early stage, but N. lugens at late stage. However, population development patterns among the five sites varied. The percentages of N. lugens in the two sites of Guangxi were 60.4% to 91.3%， but those of N. muiri in Linxiang, Hunan and Fuyang, Zhejiang were 59.3% to 80.7%. N. lugens started to appear under light trap in April, became dominant in June and showed two peaks at JuneJuly and October (or OctoberNovember) in the two sites of Guangxi, but started to appear under light trap in MayJune, became dominant in September, and showed only one peak at SeptemberOctober in the other three sites. Therefore, it is very important to identify specimens caught under light trap for improving brown planthopper forecasting.

Key words： Nilaparvata lugens; Nilaparvata muiri; Nilaparvata bakeri; light trap; dynamics; forecast
