在赣南对柑桔木虱成虫的产卵习性进行了系统研究。发现柑桔木虱成虫产卵前历期与温度和柑桔新梢密切相关。在田间有新梢的情况下,产卵前历期为3~16d,平均气温为25.2℃时历期最短,仅3~5d。在没有新梢时成虫仍会交配,但要等到柑桔萌发新梢才产卵。柑桔木虱成虫将88.04%的卵产在叶腋和长度小于2cm的嫩叶上。在产卵始盛期,85.84%的成虫在柑桔新梢嫩芽上活动,此时是喷药防治柑桔木虱成虫的最佳时期。
In southern Jiangxi citrus psylla adult spawning habits were systematically studied. It was found that the duration of oviposition before the adults of Citrus psyllid was closely related to temperature and citrus shoots. In the case of a shoot in the field, the period before spawning was 3 ~ 16d, and the average duration of 25.2 ℃ was the shortest, only 3 ~ 5d. Adults will still mate without new shoots, but wait until new shoots are sprouted by the citrus to lay eggs. Adult Citrus psyllid adults produced 88.04% of the eggs on leaf axils and on young leaves less than 2 cm in length. At the beginning of oviposition, 85.84% of the adults were active on the shoots of citrus shoots, which was the best time to spray the adults against citrus psylla.
