我省主要蔗区地处亚热带,气侯温和、雨量充沛,耕作制度复杂,害虫发生种类繁多,为害重。由于蔗株高大茂密,生长期长,施药困难,靠大量施用农药或某种单一手段进行防治,非但成本高;也难达到长期控制害虫的目的。因此,合理的防治法应在农业技术防治的基础上,把生物防治和化学防治协调起来,取长补短,相辅相成,既充分发挥自然界生物因子控制害虫的作用,又
The main sugar cane area in our province is located in the subtropical zone, with mild climate, abundant rainfall, complicated farming system, wide variety of pests and serious damage. Due to the high and dense cane plant, long growing season, difficult application and large-scale application of pesticides or some single means of control, not only the cost is high; it is also difficult to achieve long-term control of pests. Therefore, a reasonable prevention and control law should be based on the prevention and treatment of agricultural technology, biological control and chemical control should be coordinated to complement each other and complement each other, not only give full play to the natural biological factors control the role of pests, and
