在温室中一定的隔离条件下,测试了温室白粉虱对5种蔬菜的偏好性,结果表明,温室白粉虱的成虫对5种蔬菜植物的偏好性具有一定的差异。其偏好性由强到弱依次为菜豆、番茄、黄瓜、大葱和香菜。在菜豆上的卵和若虫的密度分别达10.61粒/cm2、10.22头/cm2,在大葱和香菜上未见产卵。本研究的结果为利用间作或轮作,种植温室白粉虱喜好或不喜好的寄主植物诱集和驱避其产卵,从而减轻为害提供了一定的依据。
The green house whiteflies were tested for their preference for the five vegetables under certain conditions of isolation in the greenhouse. The results showed that there were some differences in the preference of greenfly whiteflies among the five vegetable species. The preference from strong to weak was followed by kidney bean, tomato, cucumber, green onion and coriander. The density of eggs and nymphs on the beans were 10.61 grains / cm2 and 10.22 grains / cm2, respectively. No eggs were found on green onions and coriander. The results of this study provide a basis for the use of intercropping or rotation, planting green housefemale whitefly preference or dislike host plants to trap and repel their eggs, thereby reducing the damage.
