棉花盲蝽蟓近年来在长江流域棉区对棉花的为害和损失逐年加重,已成为主要害虫。但在中黑育蝽和绿盲蝽二种棉盲蝽中对中黑盲蝽的坐活规律如越冬情况等了解不多。中黑盲蝽的越冬场所,在本地仍以棉田的棉株为主,越冬卵的原始部位主要是在棉株的中部和上部叶片的叶柄上,它的产卵部位习性与冬前世代相同,只是越冬代的卵,随着叶片和叶柄从棉株上的脱落而留在地面上。叶片和叶柄枯烂以后,部份的卵粒散落于土面和土壤缝隙中,因此在棉茬的表土中也可以找到部份中黑盲蝽的越冬卵粒,但土壤中的越冬卵只占地面越冬卵粒的小部份,大部份越冬卵粒在地面的枯枝落叶之中。我们在11月间调查本所棉田中,每100个点(每点一平方尺)中
In recent years, the damage and loss to cotton in cotton area of the Yangtze River valley have been increasing year by year and have become the major pests. However, in the two black bug and Apolygus lucorum two kinds of cotton bug on the black Apis mellitus living law, such as overwintering situation, do not know much about. Lygus in the overwintering site, the cotton field in the local cotton is still the mainstay, the original part of the winter wintering eggs are mainly in the middle of the cotton plant and upper leaf petioles, and its habitat of spawning sites and winter before the same generation, Just overwintering eggs, which remain on the ground as the leaves and petioles fall from the cotton plant. After rotting leaves and petioles, part of the eggs scattered in the soil surface and soil cracks, so cotton stubble topsoil can also be found in part of the black Lygus bug overwintering eggs, but the soil of the overwintering eggs only The overwintering part of the ovoid surface of the ground, most of the wintering eggs in the ground among the litter. In November, we investigated every 100 points (one square foot per site) in our cotton field
