引言 暗黑金龟甲是花生田蛴螬中危害猖獗的一个优势虫种,全国主要花生产区都有发生,其中山东省发生面积200余万亩,损失惨重。1977—1984年我们进行了探索性的研究,最初,将粮田蛴螬的防治方法移植来防治花生田蛴螬,经过试验未获成功。为了进一步的探索新的防治办法,根据暗黑金龟甲飞翔力强、田外嗜食高树寄主叶片,最后飞回花生田产卵的习性,对暗黑金龟甲在花生田的产卵位置、临产期卵巢的形态特征及田间的活动规律,采用预测卵临产期的方法,对用药适期、有效药剂的种类等进行了系统的研究,取得了明显的效果,现将所得资料整理如下。
Introduction Diabrotica is one of the predominant pest species that is rampant in peanut fields. The major flower-producing areas in the country have occurred, of which more than 200 million mu have occurred in Shandong Province, causing heavy losses. From 1977 to 1984, we conducted exploratory research. Initially, the prevention and control of peanut fields were prevented by transplanting the control methods of grain mullet, which was unsuccessfully tested. In order to further explore new methods of prevention and treatment, according to the flying of dark-brown tortoiseshell strong, outdoor diet tree host blades, and finally flew back to peanut spawning habits, the black-tortoise shell in the peanut spawning position, Morphological characteristics of the field and the law of the field, the use of predictive methods of egg production period, the right medication, the type of effective agents were systematically studied and achieved significant results, the information is summarized as follows.
