绿盲蝽成虫的产卵行为与习性

本文观察记录了绿盲蝽Apolygus lucorum(Meyer-Dür)雌性成虫的产卵行为,并研究了其产卵习性。结果发现,绿盲蝽卵主要产在植物组织中,单次产卵平均历时31.4 s;产卵主要在夜间进行,白天的产卵量仅占全天的6.6%。成虫交配后主要产可育卵,后期偶产不育卵;而未交配个体大部分能产不育卵。在25℃下,成虫从7日龄起开始产卵,16日龄前产卵量占总产卵量的48.9%;17～40日龄间产卵量约占40%。在棉株上,约65%卵分布在中部(第4到第7果枝),同时94.3%卵集中在叶柄、叶脉、蕾柄和铃柄上。

Oviposition behavior of adult female Apolygus lucorum

We studied the oviposition behavior of adult female Apolygus lucorum （Meyer-DUr） and their oviposition habits. The results show that A. lucorum usually lays eggs inside plant tissues and takes 31.4 s to lay one egg. Most eggs are laid at night with only 6.6% laid in daytime. Mated females mainly lay fertile eggs but sporadically lay infertile ones during the last egg-laying period. Many unmated female individuals also lay infertile eggs. At 25＊C, females began to lay eggs 7 days after eclosion; 48.9% of all eggs were laid from this time until the 16th day, and 40% from the 17th to the 40th day. On cotton plants, approximately 65% of eggs are laid in the middle of the plant （i. e. the 4th to 7th fruit-bearing branches） and 94. 3% are laid inside leafstalk veins, square stems and bell stems.
