Embodiment Construction

[0026] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0027] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions:

[0028] A method for overwintering and breeding of aphidia sylvestris populations of the present invention comprises the following steps:

[0029] (1) Host plant cultivation:

[0030] In the greenhouse, adopt the soil that has added fungicides and insecticides to cultivate Asteroides spinosa, and cultivate a batch every 10-15 days, and each batch is cultivated for 25-30 days; to ensure that there are enough host plants for standby;

[0031] (2) Aphid inoculation:

[0032] Collect second-, third- and fourth-instar wingless nymphs that have not been parasitized as aphid speci...

Abstract

The invention discloses an overwintering breeding method for an aphidius gifuensis population. The method comprises the following steps that 1, host plant breeding; 2, aphid inoculation; 3, aphid breeding; 4, aphidius gifuensis inoculation; 5, aphidius gifuensis breeding; 6 reproduction expanding. In a greenhouse with controllable environment conditions, alligator alternanthera herbs are planted, aphidius gifuensis is bred for overwintering, the characteristic that the aphidius gifuensis survives and propagates easily is fully utilized, it can be ensured that the aphidius gifuensis is supplied on a large scale all year round, the aphidius gifuensis can be produced and bred continuously and circularly by means of the technology, the defects that it is difficult to preserve the aphidius gifuensis in an overwintering mode by means of the aphidius gifuensis breeding technology, the requirement for loose keeping in a tobacco field next year can not be met are overcome, and the industrialization development target of the biological prevention and control technology from laboratories to field application and popularization is achieved.

Description

technical field [0001] The invention relates to the technical field of biological control of diseases and insect pests, in particular to a method for overwintering breeding of aphids aphids 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 propagation and applicati...
