为明确丽蚜小蜂应用技术中一些配套措施的作用，在越冬番茄温室内，进行了丽蚜小蜂及配套措施联合使用控制温室粉虱效果的试验。以传统农药防治为对照（ CK），研究了3项措施联合使用技术（释放丽蚜小蜂＋温室安装防虫网＋适时清除底部老叶）、未装防虫网（释放丽蚜小蜂＋适时清除底部老叶）、未清除底部老叶（释放丽蚜小蜂＋温室安装防虫网）对温室粉虱成虫数量的影响。结果表明：3项措施联合使用的温室11月～翌年6月粉虱数量持续低于2头／株，未装防虫网的温室（释放丽蚜小蜂＋适时清除底部老叶）3月下旬～6月中旬粉虱数量从0．90头／株增加至11．99头／株，未及时清除底部老叶的温室（释放丽蚜小蜂＋温室安装防虫网）2月底～4月中旬粉虱数量从0．25头／株迅速增长至8．93头／株，农药防治的温室（ CK）自3月以后粉虱数量持续在3～5头／株。3项措施联合使用对温室粉虱的控制效果显著优于其他处理和农药防治。释放丽蚜小蜂、安装防虫网和适时清除底部老叶3项措施联合控制技术，能够较好地防治越冬番茄温室粉虱，且控制效果可持续作物整个生长期。

In order to clarify the effect of supporting measures on using Encarsia formosa, the controlling effects of combination technology ( releasing Encarsia Formosa+installing insect nets in greenhouse+clearing bottomed old leaves) , no installation of insect nets ( releasing Encarsia Formosa+clearing bottomed old leaves) , no clearing old leaves ( releasing Encarsia Formosa+installing insect nets in greenhouse) on the number of whitefly adults in greenhouses were studied with the controlling of traditional pesticide as control.The results showed that the number of whitefly adults on every plant of using combination technology in greenhouse less than 2 from November to June the following year, the number of whitefly adults in the treatment of no installation of insect nets was from 0.90 in late March to 11.99 in mid June, and the whitefly adults number of no clearing bottmed old leaves was from 0.25 in the end of February to 8.93 in mid April, it kept 3 to 5 in chemical control treatment since March.Control effect of combination technology was better than other treatments and chemical control.It followed that combination technology of three measures showed remarkable effect in control of whiteflies on overwintering tomato in greenhou-ses, and the effect was sustainable in the whole growth period of crop.
