摘要
通过虫情测报灯和田间虫情系统调查相结合的方法,调查分析了2008～2010年宁乡县回龙铺镇白背飞虱田间种群动态.结果表明:2008至2010年白背飞虱灾情有逐年增强趋势;早稻田间白背飞虱若虫、成虫数量呈“翘尾型”,晚稻向背飞虱田间若虫数量呈“昂首型”,成虫呈现“首尾双峰型”;全年白背飞虱种群数量高峰主要集中在早稻灌浆期-乳熟期和晚稻拔节期-孕穗期以及蜡熟期.
Abstract
The field population dynamics of white-backed planthopper in Huilongpu Town, Ningxiang county, Hunan province during 2008~2010 were investigated by using field investigation method and black-light-traps. The results showed that the occurrence of white-backed planthopper during 2008-2010 showed a tendency of gradual increase; the numbers of nymphae and imago of white-backed planthopper in early rice field were more in late stage; the number of nymphae of white-backed planthopper in late rice field was more in early stage; the number of imago of white-backed planthopper in late rice field was more in early stage and late stage, but less in middle stage; the peak of population number of white-backed planthopper appeared in filling-milks stage in early rice field, and in jointing-booting stage and waxy ripe stage in late rice field.
