Method for breeding aphidius gifuensis ashmeads through alternanthera philoxeroides

Abstract

The invention discloses a method for breeding aphidius gifuensis ashmeads through alternanthera philoxeroides. The method includes the following steps that 1, yellow-green type tobacco aphids are collected, and aphid species are bred after detoxification purification is conducted; 2, aphidius gifuensis ashmeads are collected, and bee species are bred after purification is conducted; 3, a breeding chamber is prepared, and alternanthera philoxeroides are cultured; 4, yellow-green type tobacco aphids are inoculated and bred; 5, inoculation is conducted on the aphidius gifuensis ashmeads, and mummified aphids are bred; 6, the mummified aphids of the aphidius gifuensis ashmeads or adult bees are collected. According to the method for breeding the aphidius gifuensis ashmeads through the alternanthera philoxeroides, the features that the alternanthera philoxeroides survive easily, breed easily and grow in four seasons are fully utilized to replace traditional tobacco, cabbages and the like to serve as carriers to breed the aphidius gifuensis ashmeads, so that the aphidius gifuensis ashmeads can be bred in the four seasons, reasonable utilization of agricultural resources is achieved, and the breeding cost is reduced; meanwhile, the aphidius gifuensis ashmeads are bred in batches, multi-generation repeated reproduction of the aphidius gifuensis ashmeads is avoided, the number of hyper-parasitoids of the aphidius gifuensis ashmeads is reduced, and the field survival ability of the aphidius gifuensis ashmeads is increased.

Description

technical field [0001] The invention relates to the technical field of biological control of diseases and insect pests, and in particular relates to a method for breeding Aphids aphids by using A. chinensis. Background technique [0002] Aphidius gifuensis has become one of the most valuable natural enemy insects in Aphidius gifuensis because of its strong fecundity, high natural parasitism rate, short generation cycle, strong adaptability and easy artificial reproduction. The bee is mainly distributed in mainland China, Taiwan, South Korea, Japan and other eastern Asian regions. It has a strong natural control over host aphids and has a wide range of hosts. Cotton aphids, eggplant netless aphids, etc., are particularly effective in controlling aphids. In tobacco fields, the parasitism rate of Aphids persicae to A. persicae is usually 20%-60%, and the highest one can reach 89.16%. In recent years, Aphids aphidis has been highly concerned at home and abroad, and its propaga...

Problems solved by technology

[0004] First, the tobacco growth cycle is long, and it often takes more than 90 days from sowing to picking up aphids, which requires a lot of manpower and material resources; second, tobacco growth requires a large space, and a single tobacco plant can grow to a height of 2 meters, requiring 1*1 Arranging tobacco cultivation at a distance of 1 meter requires a larger area for multiplication; third, the tobacco leaves are sticky, which is not conducive to the collection of parasitic bees; fourth, the collection of bees is not conducive to product storage and transportation
