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
