摘要
通过田间调查和统计分析,对棉铃虫[Helicoverpa armigera(Hübner)]在鹰嘴豆上的发生和卵、幼虫分布规律进行了较系统的研究。结果表明:棉铃虫卵64.61%集中在植株的上部,91%位于叶片的背面;56.2%和40.5%的幼虫分布在植株的上部和中部;2代棉铃虫卵、幼虫在鹰嘴豆田的空间分布型为聚集分布,符合负二项分布。
On the basis of the investigation and analysis, the results showed that the spatial distribution patterns of egg and larvae of Helicoverpa armigera （Hübner）belong to aggregate distribution pattern. The vertical distribution showed that the eggs are mainly on upper parts of the chickpea, and accounts for 64.61% of the total eggs, 91% of eggs is at the back of leaf blade. The larvae mainly distributed on the green leaf and the fruit, and accounts for 56.2% and 40.5% of the total larvae respectively.
