摘要
为掌握黑刺粉虱的发生规律,更好地控制其发生,笔者对四川省雅安市名山区牛碾坪茶园内黑刺粉虱幼虫、蛹、成虫和卵的发生动态,越冬虫态和死亡率进行调查。研究发现,名山区茶园黑刺粉虱各虫态每年有3个发生高峰期,主要以2龄和3龄幼虫越冬,不以卵越冬;卵初期为乳白色,随着时间的增加,颜色逐渐变深至淡黄色、棕黄色,最后为黄棕色,与前人描述存在差异。依据调查结果,推测黑刺粉虱在该茶区1年发生3代。
In order to master the occurrence law and better control Aleurocanthus spiniferus,the growth and decline dynamics,overwintering state and mortality of larvae,pupae,adults and eggs of Aleurocanthus spiniferus in Ming-shan tea plantations of Ya'an were investigated.The results showed that each stage of the A.spiniferus had three peak periods in one year,and the 2nd and 3rd instar larvae could live through the winter,and the eggs could not.The eggs were milky white at the beginning,and gradually deepened to light yellow,brownish yellow and finally yellow-brown with the increase of time,which was different from the previous description.According to the results of the investigation,the occurrence of A.spiniferus was presumed to be 3 generations per year.
