浙江黄岩是我国主要柑桔产区之一,位于我国东海之滨,北纬28°30′,东经121°10′。 柑桔锈壁虱是柑桔上最重要的害虫之一,受该虫为害,当年果实变成赤褐色,体变小,经济价值大降,翌年造成落叶、减产。黄岩桔农俗称锈壁虱为“铜病”。他们称“一年铜,三年穷”,意思是一年害虫大发生,要影响二、三年产量,可见锈壁虱危害之严重。该虫目前通行化学防治方法,但常用的化学农药由于有效期短或者杀卵效果差,加上害虫发生代数多,世代重叠,故防治次数多,大大增加了成本。近年来,一些地方采取越冬期进行防治,但防治效果反映不一,为究其原因。作者于1970年冬至1972年冬,在浙江黄岩桔区对柑桔锈壁虱的越冬进行了考查。本文是考查的结果。 Zhejiang Huangyan is one of the main citrus producing areas in China. It is located on the coast of East China Sea at 28 ° 30 ’north and 121 ° 10’ long. Citrus rust tick is one of the most important pests on citrus, which is harmed by the insect. When the fruit turns auburn, the body becomes smaller and the economic value drops greatly, causing deciduous foliage and reducing production the following year. Huangyan oranges called rust ticks “copper disease.” They said that “one year of copper and three years of poverty” means that pests occur a year in large quantities. To affect the output in two or three years, we can see that the rust ticks are devastating. The worm is currently used in chemical control methods, but commonly used chemical pesticides due to the short effective period or the ovicidal effect is poor, coupled with the generation of pests and more generations overlap, so the number of prevention and control, greatly increased costs. In recent years, some places have adopted the winter period for prevention and treatment, but the control effects have been mixed, for the reason. The author in the winter of 1970 to the winter of 1972, Zhejiang orange rock citrus citrus winter tick overwintering were examined. This article is the result of test.
