Diaeretiella rapae curtis carrier plant system and construction method thereof

Abstract

The invention provides a diaeretiella rapae curtis carrier plant system. According to the diaeretiella rapae curtis carrier plant system, the carrier plant is tobacco, the replaceable host is myzus persicae, and the parasite is the diaeretiella rapae curtis. By means of the diaeretiella rapae curtis carrier plant system, a good diaeretiella rapae curtis breeding effect can be achieved, a certain amount of diaeretiella rapae curtis can be applied to preventing and controlling field target injurious insects, enough myzus persicae can be left to be used for continuous breeding of the diaeretiella rapae curtis, the usage amount of chemical pesticide is reduced, and the diaeretiella rapae curtis carrier plant system plays a very big role in vegetable injurious insect preventing and controlling.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a carrier plant system of Braconus rapae and a construction method of the carrier plant system. Background technique [0002] At present, there are more than 4,700 species of aphids known in the world. They have the characteristics of many types, various hosts, wide distribution, large numbers, fast reproduction, parthenogenesis, overlapping ages, and great harm. They often gather on the buds, young leaves, and flower buds of plants. , twigs, use sharp mouthparts to suck the juice in the phloem sieve tube of the plant, and transmit the plant virus carried by it to the host plant, resulting in lack of plant vitality, reduced growth rate, stunted growth, leaf spots, and yellowing Symptoms such as leaf curling, reduced yield, and even withering and death. How to effectively control aphids has always been a problem that plagues the majority of agricultural and forestry worke...
