Abstract

The invention discloses a method for synergizing the beet armyworm nuclear polyhedrosis virus. Aiming at the defects of slow insecticidal speed and low toxicity of a single natural insect virus, the joint action of insect larvae parasitoids and viruses is used to treat the beet armyworm at the same time with the beet armyworm nucleopolyhedrosis virus, or parasitize first Bee treatment and virus treatment of beet armyworm can significantly increase the infectivity of the virus to pests. Compared with the traditional use of neurotoxic chemical pesticides to increase the effect of virus control, this technology uses the joint action of the larvae parasitic wasp scutellaria and the virus, which not only has outstanding synergistic effect, but also has high safety, which can effectively improve the biological control of pests. Level. After a large number of applications in production, the economic, social and ecological benefits will be very significant.

Description

1. Technical field

[0001] The invention belongs to the technical field of pest biological control, and in particular relates to a method for improving the infectivity of beet armyworm nucleopolyhedrosis virus by using the mottled wasp. 2. Technical background

[0002] As a kind of biopesticide, insect virus is obviously superior to other insecticides because of its high pathogenicity to target pests, its ability to spread naturally in the pest population for a long time, and it is not easy to produce drug resistance. People pay attention. However, a single virus insecticide often has the disadvantages of slow insecticidal speed and ineffective effect, which greatly restricts its application in production.

[0003] Aiming at the defects of a single natural insecticidal resource, researchers have been looking for various ways to overcome their shortcomings for many years. However, the main research focuses on how to use genetic engineering or chemical methods to improve the ...
