本文报道肚倍蚜各虫型及同虫型各世代的发生数量及瘿内、瘿外时期的数量变动。据1990～1992年的研究结果,该蚜近3个月的瘿内时期,数量增长3000多倍,而瘿外时期又激剧下降。倍子体积的增长与瘿内蚜量成正相关。同批倍蚜跨年度完成生活史,有的一年,有的两年甚至更长。头年至翌年春,侨蚜的存活率为0.3％～1.5％;其中,性母约占40％,羽化后完成生活史,使虫口数量增长40～180倍。第二年至第三年春在冬寄主上的侨蚜仅存活0.01％,羽化的性母比例更低,于种群增长无意义,在生产上应利用一年完成生活史的虫群。
In this paper, the number of each species and the same worm of Allopteryx mori were reported. According to the results of the 1990-1992 study, the number of mosquitoes increased by more than 3,000 times in the three months of the Reign period and sharply declined in the third period. The increase of Pleurotus ostreatus is positively correlated with the amount of Aphis gossypii. The same batch of aphids completed life history across the year, some one year, some two years or even longer. In the first year to the next spring, the survival rate of Myzus persicae is 0.3% -1.5%. Among them, 40% are female and about 40-180 times as many as the population life after eclosion. The second year to the third year of spring in winter, the host aphid survived only 0.01%, the proportion of sexual mother emergence is lower, the growth of the population meaningless, the production should be used to complete the life cycle of the swarm.
