摘  要：
通过培养皿内自由扩散观察和生物学观察,对黄瓜、茄子、辣椒、棉花和甘薯上B型烟粉虱的寄主选择性和生物学参数进行了研究.结果表明:B型烟粉虱成虫向寄主植物叶片自由扩散的初始阶段(2h),各寄主植物叶片上虫量的差异不大,在随后的4～48h内黄瓜叶片上的虫量不断增加,茄子、棉花和甘薯叶片上的虫量相对稳定,而辣椒叶片上的虫量却不断下降,说明B型烟粉虱对黄瓜的选择性最强、对辣椒的选择性最弱,且饥饿和吡虫啉预处理均不影响B型烟粉虱的寄主选择性;取食不同寄主植物烟粉虱成虫的蜜露分泌量差异显著,从高到低依次为黄瓜、甘薯、棉花、茄子、辣椒;黄瓜、茄子、甘薯、棉花上烟粉虱成虫的寿命显著长于辣椒,其平均单雌产卵量(分别为224.33粒、182.33粒、191.73粒和172.60粒)也均显著高于辣椒(47.83粒);各寄主植物上烟粉虱卵的孵化率和发育历期差异均不显著;烟粉虱若虫在黄瓜、茄子、甘薯和棉花上的发育历期分别为10.60d、11.96d、11.11d和13.20d,死亡率分别为5.21%、27.78%、17.24%和37.11%,在辣椒上不能完成正常发育.

摘  要：
Based on the observation of free diffusion in petri dish and biology,the selection behavior and biological parameters of Bemisia tabaci Gennadius biotype B on host plants cucumber,eggplant,pepper,cotton,and sweet potato were investigated.No difference was observed in the individual number of B.tabaci on the five host plant leaves during the early period of free diffusion(within 2 h),but changes were found within the following periods(4-48 h),i.e.,the B.tabaci individuals increased on cucumber,decreased on pepper,and were relatively stable on eggplant,cotton,and sweet potato,which indicated that there were significant differences in the selectivity of B.tabaci on the five host plants,with the highest selectivity to cucumber and the lowest selectivity to pepper.Pretreatment by starvation and imidacloprid did not affect the selectivity of B.tabaci.There were significant differences on the honeydew excretion of female B.tabaci adults on the host plants,which was in the order of cucumber>sweet potato>cotton>eggplant>pepper.The average longevity of B.tabaci adults on cucumber,eggplant,sweet potato,and cotton was significantly longer than that on pepper,and the total number of eggs laid per female on cucumber,eggplant,sweet potato,and cotton(224.33,182.33,191.73,and 172.60 respectively)was significantly larger than that on pepper(only 47.83).No significant differences were observed in the hatching rate and development period of the eggs on the five host plants.The development period of nymphs on cucumber,eggplant,sweet potato,and cotton was 10.60 d,11.96 d,11.11 d,and 13.20 d,and the mortality was 5.21%,27.78%,17.24%,and 37.11%,respectively.The nymphs failed to develop normally on pepper.
