Effect of host plants on the development and reproduction of Bemisia tabaci (Homoptera: Aleyrodidae)
不同寄主植物对烟粉虱发育和繁殖的影响

The development, survivorship and reproduction of B. tabaci B\|biotype on 4 commercially grown vegetables were studied in laboratory. The total survivals from egg to adult on collard ( Brassica oleraceal var. acephala L.), eggplant ( Solanum melongena L.), tomato ( Lycospersicum esculentum Mill.) and cucumber ( Cucumis sativas L.) were 68 55%, 66 75%, 54 61% and 46 28%, respectively. The developmental periods from egg to adult varied from 17 5 days on eggplant to 19 3 days on cucumber. The average longevity of adult females ranged from 25 2 days on collard to 17 2 days on cucumber, while the ovipositon of B.tabaci varied from 143 eggs on collard to 98\^25 eggs on cucumber. The intrinsic rates of natural increase ( r m ) for B.tabaci on eggplant was the highest. According to the parameters mentioned before, eggplant was the most suitable host plant for B.tabaci in this studyt.
