B型烟粉虱在四种葫芦科寄主植物上的发育和繁殖

研究了B型烟粉虱在4种葫芦科寄主植物黄瓜、节瓜、苦瓜和丝瓜上的发育和繁殖特性.结果表明，B型烟粉虱在节瓜上的世代发育历期最短，为19.3 d，在苦瓜上的世代发育历期最长，为29.0 d；世代存活率在黄瓜上最高，为92.85％，在苦瓜上最低，为53.08％；平均单雌产卵量在黄瓜上最多，为187.4粒，苦瓜上最少，为30.0粒；雌成虫寿命以在黄瓜上最长，为25.2 d，在苦瓜上最短，为10.9 d.B型烟粉虱在黄瓜、节瓜、苦瓜和丝瓜上的内禀增长率（r_m）分别为0.1453、0.1429、0.0616和0.1055.综合比较4种葫芦科植物，黄瓜是B型烟粉虱的最适宜寄主.

Development and reproduction of B-biotype Bemisia tabaci on four cucurbitaceous host plants.

The study on the development and reproduction of B-biotype Bemisia tabaci on four cucurbitaceous host plants, i. e., cucumber, hairy gourd, bitter cucumber, and sponge gourd, showed that the one generation development duration of B. tabaci was the shortest (19.3 d) on hairy gourd and the longest (29.0 d) on bitter cucumber, the survival rate from egg to adult was the highest (92.85%) on cucumber and the lowest (53.08%) on bitter cucumber, the laid eggs were the most (187.4 eggs per female) on cucumber and the least (30.0 eggs per female) on bitter cucumber, and the longevity was the longest (25.2 d) on cucumber and the shortest (10.9 d) on bitter cucumber. The intrinsic rate of increase (r(m)) on cucumber, hairy gourd, bitter cucumber, and sponge gourd was 0.1453, 0.1429, 0.0616, and 0.1055, respectively. Among the test cucurbitaceous host plants, cucumber was the most suitable host plant for B. tabaci.
