在安徽茶区采获茶园害虫寄生性天敌昆虫107种,鉴定了66种,分属于2目15科。主要有茧蜂、小蜂、缘腹卵蜂和寄蝇等类,均对害虫具有较大的自然控制效应。茶园山林植被繁杂,有利于多种寄生性天敌昆虫的生存繁衍;大量施用农药,则对天敌昆虫威胁很大。作者认为应发展生物防治,建立良好的茶园生态系,充分发挥寄生性天敌昆虫对茶园害虫的制约效应。
107 species of parasitic natural enemies of tea plantation pests were harvested in the tea area of Anhui Province, of which 66 species were identified, belonging to 2 orders and 15 families. Mainly Braconion bee, small bee, flies and flies and other types of flies, all of the pests have a greater natural control effect. Vegetation in the tea plantation is complex and is conducive to the survival and reproduction of many kinds of parasitic natural enemies. Large-scale application of pesticides poses great threats to natural enemies. The author believes that biological control should be developed to establish a good tea garden ecosystem, give full play to the parasitic natural enemies of insect pests on the tea control effect.
