摘要
为了解B型烟粉虱(Bemisiatabaci)在不同寄主植物上的生物学特性,以制定科学的综合治理措施,作者在271℃的条件下,研究测定了B型烟粉虱在棉花(Gossypiumhirsutum)、一品红(Euphorbiapulcherrima)、甘蓝(Brassicaoleraceavar.capitata)、黄瓜(Cucumissativus)、西葫芦(Cucurbitapepo)、茄子(Solanummelongena)和番茄(Lycopersiconesculentum)上各虫态大小、成活率、发育历期、成虫寿命、平均产卵量等生物学参数。结果表明:取食不同寄主植物的烟粉虱伪蛹在黄瓜和棉花上体型最大,在一品红上最小;烟粉虱从卵到成虫羽化,发育历期以在一品红上最长(22.0d),黄瓜上最短(17.3d);平均单雌产卵量以在番茄上最多(266.5粒/雌),一品红上最少(112.9粒/雌);成虫的寿命在番茄、黄瓜和茄子上显著长于在其他4种寄主植物上。烟粉虱从卵发育到成虫的存活率以在黄瓜上最高(77.8%),西葫芦上最低(55.6%),两者差异显著。综合比较7种寄主植物,黄瓜是烟粉虱种群生长发育和繁殖的最适寄主。
We studied the body size, development, longevity, fecundity and survivorship of Bemisia tabaci biotype 8 on cotton （Gossypium hirsutum）, poinsettia （Euphorbia pulcherrima）, collard （Brassica oleracea var. capitata）, cucumber （Cucumis sativus）, squash （Cucurbita pepo）, eggplant （Solanum melongena）, and tomato （Lycoperxicon esculentum） at 27 ± 1 ℃, 75% RH and a photoperiod of 14：10 （L：D） h in the laboratory. We found that the pupae size on cucumber and cotton was the largest whereas that on poinsettia was the smallest. The developmental periods from egg to adult varied from 17.3 days on cucumber to 22.0 days on poinsettia. Fecundity varied from 266.5 eggs on tomato to 112.9 eggs on poinsettia, while the average longevity of adult females on tomato, cucumber and eggplant was longer than that on the other plants. The total survivorship from egg to adult on cucumber, poinsettia, cotton, eggplant, collard, tomato and squash was 77.8%, 70.6%, 67.9%, 67.8%, 65.0%, 59.0%, and 55.6%, respectively. An overall comparison of performance on the seven plant species indicates that cucumber is the most suitable host plant for B. tabaci biotype 8.
