柑桔蚜虫种类及其发生为害的考查(同翅目:蚜科)

1984～1986年的调查结果表明,为害我省柑桔的蚜虫有绣线菊蚜Aphis citricola van derGoot、棉蚜A.gossypli Glorer、豆蚜A.craccivora Koch、枯蚜Toxoptera citricidtt s(Kirkaldy)、枯二叉蚜T.aurantii(Boyer de Fonscolomhe)、桃蚜Myzus persicae(Sulzer)和樟修尾蚜Sinomegoura citricola(van der Goot)7个种。其中豆蚜为我国柑桔害虫新记录,绣线菊蚜是本省柑桔蚜虫的优势种,共次为棉蚜和枯蚜。柑桔新梢有蚜率可达80％以上。几种蚜虫常混合发生。夏秋梢受害比春梢重,幼年树,肥水条件好和靠近村庄的果园受害较重。文中还讨论了柑桔蚜虫优势种的演替问题。

AN INVESTIGATION ON CITRUS APHIDS, THEIR OCCURENCE AND DAMAGE (HOMOPTERA, APHIDIDAE)

In the 1984-1986 survey of aphids attacking citrus in Fujian, seven species of aphids were found, namely, Aphis citricola van der Goot, A. gossypii Glover, A.craccivora Koch, Toxoptera citridus (Kirkaldy), T. aurantii (Boyer de Fonscolombe), Myzus persicae (Sulzer) and Sinomegoura citricola (van der Goot). Among them, A.citricola, A. gossypii and T. citricidus ranked the predominant species. A.citricola was the most damaging aphid.The infestation appeared all over the citrus growing areas in Fujian. More than 80% of the citrus new shoots were attacked by the aphids, several species of aphid could be found at the same time. Their feeding that injured the new shoots of summer and autumn was much more serious than that of the spring. Those citrus orchards near villages with good managements and with good young growths were much more susceptible and damaged heavily by the aphids. A discussion on the succession of the predominant citrus aphid is also given.
