甘蔗棉蚜的生活习性,有不少文献记载它是以有翅成虫在大芒骨上过冬,广东、广西、四川每年在5—6月间始在蔗田发现,而以8—10月最多,11月有翅成虫开始出现,交尾后四处飞散产卵胎生若虫,12月中旬的有翅成虫停止交尾,飞往大芒骨上过冬,至翌年甘蔗苗长出后,又复迁回蔗田为害。 但我们在下放到广西桂平县先锋人民公社期间,在2月上旬天气较严寒的时候,还发现有有翅成虫在去年的秋植蔗苗上;至3月上旬又发现有不少无翅型的成虫、若虫在秋植蔗田为害。由此可见甘蔗棉蚜并没有飞往大芒骨上越冬,而是在秋植蔗上越冬,这是由于该公社立岭生产大队处于平原地带,附近没有大芒骨,因此棉蚜即飞往秋植蔗上越冬,到天气逐渐温暖的3
There are many documents about the life habits of sugarcane aphids in the world. It is based on winged adults of winged adults in the big mantle. Guangdong, Guangxi and Sichuan are found in sugarcane fields from May to June every year, while in most of August to October , Winged adults began to appear in November, after the mating four scattered natal viviparous nymphs, winged adults in mid-December to stop mating, fly to the big spines on the winter, to grow the next year after the sugarcane seedlings, and moved back to the sugarcane Harmful. However, during the delegation to Pioneer People’s Guiping County, Guangxi, in the early February when the weather was even colder, we found a winged adult on the autumn planting sugarcane seedlings last autumn. In early March, we found a lot of wingless Of adults, nymphs in autumn cane damage. This shows that the sugarcane aphid did not flew to the big mantle overwinter, but winter over the autumn sugarcane, which is due to the commune ridge production brigades in the plains, there is no big mast nearby, so the cotton aphid flew Fall winter cane on the snow, the weather gradually warm 3
