摘要
福州地区为害柑桔的蚜虫有7种。绣线菊蚜 Aphis citricola van der Goot为秋季重发型;棉蚜 A.gossypii Glover春、夏发生为主,桔蚜 Toxoptera citricidus(Kirkaldy)为全年轻发型。春季蚜虫的虫源以迁入为主。有翅蚜梢率和有翅胎生蚜的数量与受害程度之间有显著相关性。柑桔新梢的抽发时期、数量和成熟的快慢对蚜虫种群的变动产生重要影响。
There are seven species of aphids feeding on citrus in Fuzhou Area,in which only three are of importance.Aphis citricola van der Gootis abundant in autumn;A.gossypii Glover mainly occurs in springand early summer;and Toxoptera citricidus (Kirkald) yis light injuriousthroughout the growing season.The aphid origin in spring is immi-grant,followed by a diffuse procession from early infested point.Thereis close relationship between the damage to citrus and alate infestedshoot as well as the amount of alate viviparae.The effect of sprou-ting time,speed of maturity and quantity of citrus shoot on aphidpopulation dynamics is significant.
