英山县地处鄂东,毗邻安徽,是一个多山县,种植红小豆、绿豆、饭豆有较长历史。近年由于农副产品调价并推行联产责任制,农民种杂豆的热情进一步高涨。1985年杂豆总产量由1980年151万斤猛升到275万斤。“杂豆好种不好留,存放半月出豆牛”,绿豆象的危害使豆类造成大量损失。虽然我们广泛地开展了对绿豆象的防治并向农民传授储藏知识,取得了一定的收效,但虫蚀率仍在15—20%。虽然绿豆象食性不复杂,但发生面广,适应性强,破坏性大,是一种主要害虫。对其发生条件、行为习性和生活史等,文献虽有报导,但很笼统,各说不一。鄂东地区的英山县绿豆象的繁殖又有什么区域性特点,也是一个问题。为此,地区粮食局提出课题及研究方案,地、县、所三级科技人员于1982年10月—1983年8月在英山县杨柳粮管所,对绿豆象的危害状况及其防护措施,进行了一系列研究,取得了宝贵的实际材料,有些数据曾于1985年在《武汉粮油科技》第二期上发表。1984年6月起至1985年8月底止,又在英山县金铺粮管所进行扩大试验,研究绿豆象生长繁育环境及其世代生活史状况。现把鄂东地区绿豆象生长繁育规律及其世代延续等情况整理如下。
Yingshan County is located in eastern Hubei Province, adjacent to Anhui, is a mountainous county, planting red beans, mung beans, beans have a long history. In recent years, due to the price adjustment of agricultural and sideline products and the implementation of the joint responsibility system, peasants are even more enthusiastic about growing beans. The total soybean output in 1985 soared from 151 kilos in 1980 to 2.75 million kilograms. “Good beans are not good to stay a good kind of beans stored half a month,” the dangers of mung bean bean caused a lot of damage. Although we have carried out extensive prevention and control of mungbean elephants and imparted storage knowledge to farmers and achieved some success, the rate of pest eutrophication is still 15-20%. Although mung bean elephants are not complicated, they occur widely, are highly adaptable and destructive and are major pests. The conditions of occurrence, behavioral habits and life history, although the literature has been reported, but very general, different. What is the regional characteristics of the reproduction of the mung bean in Yingshan County in eastern part of Hubei Province? It is also a question. To this end, the Regional Food Authority proposed topics and research programs, prefectures and counties, the three scientific and technological personnel in October 1982 - August 1983 Yangshan Willow County Cornwall, on the status of mung bean and its protective measures , Conducted a series of studies and obtained valuable practical materials. Some of the data were published in the second phase of “Wuhan Cereals and Oils Science and Technology” in 1985. From June 1984 to the end of August 1985, it was expanded in Jinpu Grain Pipe Office of Yingshan County to study the growth and reproduction environment of Mung Bean Elephant and its life history. Now the eastern part of the eastern region of mung bean growth and reproduction law and its continuation of the situation as follows.
