Embodiment Construction

[0045] With the harvesting of tobacco leaves, aphids will no longer cause harm in the tobacco fields after August each year, and a large number of bee breeding and bee release work will be completed. Only when aphids occur in the tobacco fields in May of the next year will a large number of aphid cocoons be needed. The bees are scattered in the tobacco fields. Therefore, from August to February of the next year is a critical period for seed preservation, purification and rejuvenation. It is only necessary to preserve a sufficient number of seed bees for a large number of bees. Among them: August-October It is the greenhouse seed selection period, November-January is the winter greenhouse conservation or low-temperature storage bee period, and February-April is the greenhouse bee species expansion breeding or low-temperature storage period.

[0046] Specifically, the method for overwintering species conservation and breeding of Aphidius sylvestris of the present invention compri...

Abstract

The invention relates to an overwintering preserving breeding method for an aphidius gifuensis and belongs to the technical field of biological control. The overwintering preserving breeding method for the aphidius gifuensis solves the problem that in the prior art, overwintering preservation is performed on the aphidius gifuensis difficultly, and the heavy demand for the aphidius gifuensis in a tobacco planting season in a coming year is difficult to meet. The overwintering preserving breeding method comprises a first step of greenhouse aphidius gifuensis selection which comprises cultivation of host plants, collecting of an aphidius gifuensis source, aphidius gifuensis inoculation in a greenhouse, and purification and rejuvenation; a second step of winter greenhouse aphidius gifuensis preservation which comprises cultivation of aphidius gifuensis preserving plants, aphidius gifuensis inoculation in the greenhouse, and purification and rejuvenation; and a third step of expanding propagation in the greenhouse. The aphidius gifuensis is successfully accumulated and preserved during the time from finish of massive reproduction of the aphidius gifuensis in August to April in a coming year and before massive reproduction of the aphidius gifuensis, and the aphidius gifuensises with enough quantity and good quality are provided for massive reproduction of the aphidius gifuensis in a next year.

Description

technical field [0001] The invention belongs to the technical field of biological control, and in particular relates to a technology for seed conservation and breeding of Aphids persicae in winter. Background technique [0002] At present, the use of artificial multiplication and release of Aphids persicae to control and control the important pests of tobacco fields—Aphis persicae has achieved good results. The area of ​​releasing A. The control cost of Aphids aphids, Aphids aphids control technology has broad application prospects in biological control, is the "insects to control insects" pollution-free green biological pest control system engineering core. [0003] After August every year, with the harvest of tobacco leaves, aphids will no longer cause harm in the tobacco fields, and a large number of bees and bees will be released. When aphids occur in the tobacco fields in May of the next year, a large amount of tobacco will be needed. Aphids scatter in the tobacco fiel...
