摘要
为了了解我国山东西北部地区温室大棚内外烟粉虱越冬情况,我们于2015年1月份在禹城2种不同控温方式温室大棚(高温棚和低温棚)内番茄植株上和温室大棚内外杂草上调查了烟粉虱的越冬状况。结果表明,在该地区低温棚内烟粉虱以卵和伪蛹越冬,在温室大棚内外杂草上未发现烟粉虱;在高温棚内,烟粉虱各个虫态都有发现,在高温棚内外的杂草上也发现一些烟粉虱成虫。低温大棚内烟粉虱以卵和伪蛹越冬,这一结果暗示了烟粉虱的卵和伪蛹比成虫和若虫阶段有更强的抗寒能力;另一方面推测在露地上,该虫在1月份4℃等温线左右以北还有一个以卵和伪蛹越冬的区域。此外,高温大棚外杂草上发现烟粉虱成虫,说明烟粉虱在冬季也具有扩散能力。
To understand overwinter characteristics of Bemisia tabaci in and out greenhouse in the northwest of Shandong province in China, we investigated overwinter situation of B. tabaci on tomato plant in greenhouse and on weed in and out greenhouse （high temperature greenhouse and low temperature greenhouse） in January 2015. The results showed that B. tabaci overwintered as egg and pseudo-pupa on tomato plant in low temperature greenhouse, and non B. tabaci was found on weed in and out greenhouse. While all stages of B. tabaci was found on tomato plant in high temperature greenhouse, and the same B. tabaci was found on weed in and out greenhouse. These results indicated that egg and pseudo-pupa had a stronger cold resistance than larval and adult, because only egg and pseudo-pupa were found in low temperature green house. On the other hand, it was inferred that B. tabaci could overwinter as egg and pupa in open field in the north of geo-isotherms of 4 ℃ in January. Besides, it was indicated that B. tabaci had some potential to spread in winter, because the adults were found on weed out high temperature greenhouse.
