蜡蝉(lancernfly)是植物的一大类害虫。据周尧等报道,国内为害柑桔的蜡蝉有12种。近年来,蜡蝉在宜昌地区已上升为柑桔的主要害虫。蜡蝉主要以其成、若虫吸取寄主叶片及嫩梢的汁液,造成叶片脱落和枝梢枯萎,其间接为害是,由于蜡蝉分泌的蜜露,导致煤污病的普遍发生,从而妨碍叶片同化作用的进行,造成树势衰弱,严重影响柑桔产量和品质的提高。为了弄清宜昌地区为害柑桔的蜡蝉种类及主要种类的生活史,以便为防治提供依据,我们于1983-1986年在湖北宜昌地区进行了调查,现将初步结果整理如下。
Lancernfly is a large group of plant pests. According to Zhou Yao and other reports, there are 12 kinds of wax cicadas harming citrus in China. In recent years, wax cicada in Yichang has risen to citrus pests. Wax cicada is mainly its nymphs take host leaves and tender shoots of juice, causing the leaves off and shoots withered, the indirect damage is due to the honeydew secreted by wax cicada, leading to widespread occurrence of coal pollution, thus impeding the assimilation of leaves Of the progress, resulting in frail weakness, seriously affecting the citrus yield and quality improvement. In order to find out the types of cicadas and the life history of the main types of citrus damaged by Yichang in order to provide the basis for prevention and treatment, we conducted a survey in Yichang, Hubei Province from 1983 to 1986. The preliminary results are summarized as follows.
