茶尺蠖是我国茶树的主要害虫,而茶尺蠖幼虫期天敌的研究是生物防治茶尺蠖的主要研究内容之一。通过1973—77年研究,基本查清茶尺蠖幼虫期寄生天敌种类、田间自然寄生率消长情况,主要天敌的生物学特性,并提出了在生物防治上应用的方法。一、共养出五种原寄生天敌,即茶尺蠖绒茧蜂、单白棉绒茧蜂、悬茧姬蜂、平庸赘寄蝇、
Tea scallop is the main pest of tea tree in our country, and the research of natural enemies in larval stage of Scylla serrata is one of the main research contents of biological control scallop. According to the research of 1973-77, the types of parasitoid natural enemies in larval stage of Paecilomyces viliiflora, the growth and decline of natural parasitism in the field and the biological characteristics of the main natural enemies were basically ascertained and the methods applied in biological control were put forward. First, a total of five kinds of parasites natural enemies were raised, that is, the foot of the cuckoo Culex pipiens beetle, single white cotton cashmere bee, hanging cocoon Ichneumon, mediocre superfluous flies,
