摘要
采用中色粘虫板(黄板)和植株调查方法在河北省固安县日光温室内研究了烟粉虱成虫在黄瓜结瓜盛期(4月下旬~5月上旬)的分布和日活动规律.结果表明,温室北边平均诱集量((668.8±663.9)头/(板·d))是南边((357.5±349.4)头/(板·d))的1.87倍;除8:00~10:00以外,其他时段内北边诱集量均显著高于南边;同时,北边植株上烟粉虱成虫数量也显著高于南边.温室东边逐日和各时段诱集量均高于西边,但差异不显著.在垂直方向,烟粉虱成虫在黄瓜所有叶片上均有分布.烟粉虱成虫从6:00~18:00各时段均很活跃,但不同时段活动水平存在差异.8:00~10:00平均诱集比例最高(25.7%±9.7%),12:00~14:00最低(13.2%±5.2%);8:00~10:00的诱集量显著高于其他时段.另外,黄板南面诱集量((352.5±186.1)头/(板·d))显著高于北面诱集量((160.7±90.4)头/(板·d)).对日光温室黄瓜上烟粉虱的监测、成虫诱杀和综合治理的意义进行了讨论.
Distribution and daily activities of Bemisia tabaci adults in solar greenhouse (east-west oriented) were investigated with yellow sticky traps (YSTs, 25 × 30 cm in size) and by plant inspection in Gu' an County, Hebei Province from late April to early May when cucumber was vigorous fruiting. Results show that the YSTs installed in the north side of the greenhouse caught 1. 87-fold more whitefly adults than those in the south side (668.8 adults/( trap· d) vs 357.5 adults/(trap-d) ). Catches within each of the five two-hour intervals from 6:00 to 18:00 by YSTs in the north side were significantly greater than in the south side with an exception of the two-hour interval from 8 : 00 to 10 : 00. Number of B. tabaci adults on plants in the north side was also significantly greater than that in the south side. In the east-west direction, catches (daily average and averages within each two- hour interval) in the east side were not significantly different from those in the west side. B. tabaci adults were more active at certain periods of time than at others during the day as indicated by the percentages of adults caught on the YSTs at different time intervals; the highest percentage of adults was caught between 8:00 to 10:00 (25.7%) and the lowest, between 12:00 to 14:00 (13.2%). When the YSTs were arranged at east-west direction, the surface facing south caught significantly more B. tabaci adults than the surface facing north. The current results are discussed with reference to monitoring, adult trapping and IPM of B. tabaci on solar greenhouse cucumber.
