摘要
在室内20℃、26℃和30℃三个设定温度条件下,研究了CF-965、NC-89和NC-82三个烟草品种对B型烟粉虱和温室白粉虱生长发育和繁殖的影响。结果表明:26℃时两种粉虱在CF-965、NC-89和NC-82三个烟草品种上的发育历期没有明显差异,但温室白粉虱卵期和若虫期的发育历期较烟粉虱依次分别延长了1.32d、2.81d和2.04d。在CF-965上,B型烟粉虱卵期和若虫期的总存活率和平均单雌产卵量分别为54.19%和55.17粒,温室白粉虱仅分别为31.99%和39.17粒;在NC-89上,B型烟粉虱卵期和若虫期的总存活率和平均单雌产卵量分别为23.47%和37.50粒,温室白粉虱仅分别为15.75%和17.25粒;两种粉虱在NC-82上卵期和若虫期的总存活率和平均单雌产卵量差异不大,表明B型烟粉虱对CF-965和NC-89的适应能力较温室白粉虱强。两种粉虱在20℃时的发育历期最长,32℃时最短,26℃时居中。20°C时烟粉虱卵期和若虫期的存活率20.96%为最低,26℃和32℃时分别达54.19%和53.29%;而温室白粉虱在32℃条件下存活率11.66%为最低,20℃和26℃时分别达31.34%和31.99%。温室白粉虱在20℃时产卵量大于烟粉虱,在26℃时的产卵量小于烟粉虱,30℃时则不能产卵,但烟粉虱成虫30℃时的产卵量仍可达21.06粒。由此说明烟粉虱在较高温度条件下的适应能力显著强于温室白粉虱。山东烟区烟草生长中期的田间平均温度多在22～30℃,适合B型烟粉虱的发生,应引起高度重视。
Development and reproduction of two whitefly species, Bemisia tabaci （Gennadius） biotype B and Trialeurodes vaporariorum （Westwood） were studied on three tobacco varieties （CF-965, NC-89 and NC-82） at 26℃, and at 20, 26 and 32℃ on the variety CF-965. Developmental times of immature stages of each of the two whitefly species were not different on the three tobacco varieties, whereas those of T. vaporariorum were 1.32, 2.81 and 2.04d longer than those of B. tabaci on CF-965, NC-89 and NC-82, respectively. Survival rates of immature stages of two species on CF-965 were the highest or higher compared with those on the other varieties. B. tabaci survived more on CF-965 （54.19%） than on NC- 89 （23.47%） and NC-82 （19.93%）, and T. vaporariorum survived the most on CF-965（31.99% ）, followed by that on NC-82 （20.01%） and that on NC-89, the lowest （15.75%）. The number of eggs deposited by B. tabaci was more on CF-965 and NC-89 than that and similar on NC-82 to that by T. vaporariorum. It suggested that adaptability of B. tabaci to CF-965 and NC-89 was stronger than that of T. vaporariorum. Developmental times of immature stages of both species were the longest at 20℃ and the shortest at 32℃, and the intermediate at 26℃. Survival rates of B. tabaci immatures reached 54.19 and 53.29% at 26 and 32℃, respectively, which were higher than 20.96% at 20℃. In contract, only 11.66% of T. vaporariorum immatures survived at 32℃ , which was lower than 31.34 and 31.99% at 20 and 26℃ , respectively. The number of eggs deposited by T. vaporariorum was more than that deposited by B. tabacl at 20℃ and was less than that at 26℃. At 32℃, T. vaporariorum did not deposit eggs any more, but each female of B. tabaci still deposited about 21. 06 eggs, which indicated that B. tabaci had better adaptability than T. vaporariorum under hot condition. We should pay highly attention to the occurrence of B. tabaci in the tobacco fields in Shandong province because the average temperature at the m
