Abstract

The invention discloses a method for increasing lipaphis erysimi breeding efficiency. The method for increasing the lipaphis erysimi breeding efficiency adopts a temperature changing mode to breed lipaphis erysimi and has the advantages that individuals of third-instar nymphs and imagoes of the lipaphis erysimi are larger than those of same-instar nymphs and imagoes in the prior art; 2, the survival rate of the imagoes of the lipaphis erysimi is increased, and the development duration of the lipaphis erysimi from spawns to the imagoes is shortened; 3, the life of lipaphis erysimi female imagoes generated through breeding is longer than those bred through a conventional mode, the lipaphis erysimi imagoes bred in a temperature changing mode are used for breeding next-generation lipaphis erysimi, and the spawning amount of female lipaphis erysimi is higher than that of lipaphis erysimi female imagoes bred through the conventional mode.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural and forestry pests, and in particular relates to a breeding method for the host of the brachyphyll wasp, the radish aphid, used in the process of biological control of agricultural and forestry pests. Background technique [0002] Yunnan is rich in crops, with many types of cooked crops, aphids are widely distributed, highly prevalent, common hazards, large amount of pesticides, single control method, poor control effect, pesticide residues and pollution, etc., have long been a difficult problem for plant protection work in Yunnan Province . In order to achieve new breakthroughs in plant protection work, since 2006, according to the requirements of the Ministry of Agriculture to "vigorously promote the green prevention and control of crop diseases and insect pests, and promote the quality and safety of agricultural products and the safety of the agricultural ecological e...
