摘要: 通过对单栋大棚番茄上烟粉虱的分布情况的调查,为烟粉虱的科学防治提供基础信息。结果表明,烟粉虱成虫、卵、低龄若虫主要集中在植株中部、上部危害,植株下部具有大量的伪蛹;在植株的中部、上部烟粉虱的成虫、卵、低龄若虫在中间垄的危害均要明显重于边垄。因此,单栋大棚内番茄上烟粉虱的防治应采用及时清除老残叶,做好在植株中上部的化学防治,以及其他物理防治方法、生物防治方法等多种手段结合的综合防治策略,同时应注意加强中间垄的防治。

Abstract: Distribution of whiteflies in single-span greenhouses were investigated in order to prvideprovide fundamental information for the control of whiteflies, this study investigated the distribution of whiteflies in single-span greenhousese. Our results indicated that the damage of adults, eggs and low instar nymphs of whiteflies were concentrated in the middle and upper part of the plant while large number of pupas were accumulated on the bottom part of the plant. The damage of adults, eggs and low instar nymphs of whiteflies in the middle and upper part of the plant in the middle ridge were more serious than that of the edge ridge. All in all, remove old leaves, chemical control focused on the middle and upper part of the plant, development of integrated management strategies of physical and biological methods together with the whitefly control in the middle ridge are effective ways for the prevention of whitefly in single-span greenhouses.
