Abstract

The invention discloses a method for improving diaeretiella rapae breeding efficiency. According to the method for improving the diaeretiella rapae breeding efficiency, lipaphis erysimi is bred in a temperature changing mode, and the method has the advantages that individuals of a lipaphis erysimi three instar nymph and an adult are larger than a three instar nymph and an adult in the prior art; the survival rate of the lipaphis erysimi is increased, and the time for the lipaphis erysimi to grow from an egg to the adult is shortened; 3, the service life of a bred lipaphis erysimi female adult is longer than that of a lipaphis erysimi female adult bred through a conventional method, the lipaphis erysimi adult obtained through temperature-changing breeding breeds the next generation of the lipaphis erysimi, and the egg laying amount of the female adult is higher than that of the lipaphis erysimi female adult bred through the conventional method; 4, the parasitism rate of the diaeretiella rapae to the lipaphis erysimi is increased. According to the method for improving the diaeretiella rapae breeding efficiency, the breeding time of a diaeretiella rapae host is shortened, and the breeding efficiency of the diaeretiella repae is improved.

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 of the radish aphid, which is the host of the aphid aphid, used in the process of biological control of agricultural and forestry pests, and a breeding method of the aphid aphid. 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 an...
