摘要
通过对大田生物群落的调查表明,蜘蛛、瓢虫、草蛉、隐翅虫、青蛙、蟾蜍等捕食性动物是烟田生态系统中的重要天敌,是调控烟田生物灾害发生发展的主要生物因子,辅以其他配套措施,可有效调控烟田生物灾害发生,减少用药,增产、增收。
The results of biome surveillances showed that predatory natural enemies of pest insects, such as spiders, ladybugs, frogs and toads were the main factors of controlling biological disasters, could adjust and control disasters effectively in crop fields, decrease pesticide applications, increase crop yields and farmers＂ incomes together with other measures.
