The invention discloses a method of improving Lipaphis erysimi breeding efficiency by using salicylic acid. Through discovery, breeding Lipaphis erysimi by adopting specific temperature and humidity and spraying salicylic acid solution has the following advantages: 1, individuals of Lipaphis erysimi three-year-old nymphs and adults are respectively bigger than those of nymphs and adults in the same age in the prior art; 2, the survival rate of Lipaphis erysimi adults is increased, and the time that the Lipaphis erysimi develops from an egg to the adult is shortened; 3, the life of Lipaphis erysimi female adults produced by breeding is longer than that of Lipaphis erysimi female adults bred in a conventional way, and after a next generation of Lipaphis erysimi is bred by Lipaphis erysimi adults obtained by breeding, the egg laying amount of females is higher than that of the Lipaphis erysimi female adults bred in the conventional way.
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...
