一、前言 黄脊竹蝗(Ceracris kiangsu Tsai)是闽西毛竹林区的大害虫。早在1951午龙岩、连城、长汀、永安四个县就有本虫发生,被害面积达3万多亩,被害竹林状如火烧。如果是当年生的新竹,被害一次,吃光全部竹叶,竹子就会枯死;老壮毛竹被害一次,虽还能生长,但当年生笋细小,或连笋都不生;如果连续被害2—3次,老壮竹也会枯死。被害而死的毛竹,内藏臭水,硬度及韧性差,很少利用价值。 笔者自195—1960年间,长住在竹蝗发生地区,结合灭蝗工作,对竹蝗的生物学特性进行了调查研究,现将几年来研究结果,报告如下。
I. Preface Ceracris kiangsu Tsai is a major pest in Moso bamboo forest area in western Fujian. As early as 1951, the insects occurred in Longyan, Liancheng, Changting and Yongan Counties. The area of the victims was 30,000 mu, and the bamboo forests were destroyed like fire. If it is the year of Hsinchu, was killed once, eat all the bamboo leaves, the bamboo will die; the old strong bamboo was killed once, although still able to grow, but when the small bamboo shoots, or even bamboo shoots are not born; if 2- 3 times, the old strong bamboo will die. Mosquito killed by the murder, possession of stinky water, poor hardness and toughness, rarely use value. From 195 to 1960, the author lived in the area where the bamboo locusts lived for a long time, and combined with the work of exterminating locusts. The biological characteristics of locust locusts were investigated and investigated. The findings of the past few years are as follows.
