摘　　要：为明确衡水地区日光温室粉虱发生规律,将温室南北向分为北面、中间、南面3个方位,沿东西向分成6段,2011年11月15日～2012年6月15日对越冬番茄整个生长季温室内不同位置的粉虱成虫发生数量进行了调查。结果表明:2011年11月15日～12月2日粉虱成虫数量由0.8头/株增长到3.1头/株,2012年3月1日～4月1日粉虱成虫数量升至3.1头/株;整个番茄生长期共调查11次,其中,南北向上有9次为北面单株粉虱数量显著高于中间和南面,东西向上不同段的单株粉虱数量有4次无显著差异、7次差异达到了显著水平(4次中间段高、2次西端高、1次东端高)。衡水日光温室粉虱成虫数量存在2个增长期,其中第1个在定植7 d后、第2个在年后3月;整个生长期温室粉虱成虫分布呈北面高于南面的趋势,东西向无明显规律。In order to clarify the occurrence regularity of whitefly in solar greenhouses of the area of Hengshui,the greenhouses were divided into three directions which were north side,center side and south side,along the east-west direction divided into six sections.The number of whitefly adults during the whole growth period of overwintering tomato plants in solar greenhouses was investigated from November 15 of 2011 to June 15 of 2012.The results showed that the number of whitely adults was rosed from 0.8 per plant to 3.1 per plant from November 15 to December 2 of 2011,and the population of whitely adults caught to 3.1 per plant from March 1 to April 1 of 2012.Eleven investigations were carried out during the whole growth period of plants,the population of whitely adults in north side was significantly higher nine times than that of middle side and south side.The population of whitely adults at east-west direction were not significantly different for four times,and were significantly different for seven times（middle side was greater four times,west was greater two times and east was greater one time）.There were two growth periods of whitefly adults in solar greenhouses of the area of Hengshui,the first peroid was in a week after plantation,the second period was in March of next year.During the whole growth period of plants,the population of whitely adults in north side was higher than south side,there was no significant difference between east side and west side.
