茶尺蠖Ectropis obligua hypulina Wehrli(鳞翅目尺蠖蛾科)是我国主要茶树害虫之一。长江下游至钱塘江流域,特别是浙江、苏南和皖南一带常有较重危害,成为当地许多生产单位的主治害虫。前人对茶尺蠖的生物学、消长规律和防治方法,有过不少研究报道。进一步对于温度与茶尺蠖发育的关系,侯建文等曾就变温对茶尺蠖第一代卵期发育的影响作过研究,其它则鲜有报道。本文系在不同恒温条件下,对茶尺蠖各虫态发育作系列观察,探明各虫态与全世代的发育起点温度与有效积温,以求对其发生规律的掌握及虫情预测的应用有所裨益。现将观察结果整理报告如后。
Ectropis obligua hypulina Wehrli (Lepidoptera moth) is one of the major tea tree pests in our country. The lower reaches of the Yangtze River to the Qiantang River, especially in Zhejiang, southern Jiangsu and southern Anhui often have more serious hazards, as many of the local production units host pests. Previous studies on the biology, growth and decline, and prevention and cure methods of tea scrofula had many reports. Further on the relationship between temperature and the development of tea scallop, Hou Jianwen et al. Had studied the effects of temperature variation on the development of the first generation of Euptela spp., While others rarely reported. In this paper, under different conditions of constant temperature, the development of each group of Chai Pei for a series of observations, to identify the development of all the insect states and the entire generation of starting temperature and effective accumulated temperature, in order to grasp the occurrence of law and the application of insect prediction Benefit. Now the results of finishing the report as follows.
