Large-scale propagation method of bactrocera cucurbitae larva parasitic wasps and psyttalia fletcheri

The invention discloses a large-scale propagation method of bactrocera cucurbitae larva parasitic wasps and psyttalia fletcheri. The method includes the steps: 1) adult bactrocera cucurbitae collecting; 2) adult bactrocera cucurbitae feeding; 3) bactrocera cucurbitae egg acquiring; 4) bactrocera cucurbitae larva propagation; 5) psyttalia fletcheri feeding; 6) psyttalia fletcheri parasitizing; 7) parasitized host collecting; 8) psyttalia fletcheri culture. A process of the method is simple, the method is low in cost and can be operated in an indoor space, year-round propagation can be achieved,large-scale popularization is easily implemented, and the parasitic ability of the psyttalia fletcheri is effectively improved. 本发明公开了一种瓜实蝇幼虫寄生蜂弗氏短背茧蜂的规模化扩繁方法，包括以下步骤：1)瓜实蝇成虫收集，2)瓜实蝇成虫饲养，3)瓜实蝇卵获取，4)瓜实蝇幼虫扩繁，5)弗氏短背茧蜂饲养，6)弗氏短背茧蜂寄生：7)已寄生寄主收集，8)弗氏短背茧蜂培育。其流程简单成本低，可在室内操作，能终年繁殖，易于大规模推广，有效提高了弗氏短背茧蜂的寄生能力。
