玉米螟俗称玉米钻心虫,是玉米,高梁,谷子等粮食作物的主要虫害,在我市一年发生三代。防治第一代玉米螟,不但对保护春玉米前期生长有密切关系,而且对减少二三代玉米螟发生基数,减轻对夏玉米的为害起着重要作用。过去防治玉米螟已习惯于在心叶中后期施用颗粒剂。但由于玉米品种,生育期,气候条件的不同,并无准确的测报数据指导防治适期。为了提高防治效果,了解玉米螟产卵及卵孵化规律,准确的预测出产卵及孵化始、盛、末期是指导生产防治的数理依据。因为害虫在田间发生,一般都是开始时个 Corn borer, commonly known as corn borer, is a major pest of corn, sorghum, millet and other food crops, occurring three generations a year in our city. Prevention and treatment of the first generation of corn borer, not only for the protection of early spring maize growth are closely related, but also to reduce the occurrence of the second and third generation corn borer, reducing the damage to summer maize plays an important role. In the past, the control of the corn borer has become accustomed to applying granules late in the heart. However, due to the different corn varieties, growth periods and climatic conditions, there is no accurate data to guide the prevention and control of the suitable period. In order to improve the control effect, understand the oviposition and ovulation rules of corn borer, accurately predict the spawning and hatching start, Sheng, the end is to guide the production of mathematical basis. Because pests occur in the field, they are generally the beginning of a
