Novel oleander hawk moth polyhedrosis virus and application thereof

Abstract

The invention discloses an oleander hawk moth virus strain. On the basis of an oleander hawk moth virus V201730, through many chemical mutagenesis experiments, a novel oleander hawk moth virus with broad-spectrum insecticidal activity and high toxicity is screened out, the culture name (classification name) is oleander hawk moth virus Nanchang strain DnCPV-2, the preservation number is CCTCC NO: V201927, the preservation date is 2019.4.29, and the oleander hawk moth virus has broad-spectrum insecticidal activity.

Description

technical field [0001] The invention relates to a novel oleander hawkmoth cytoplasmic polyhedrosis virus and application thereof, belonging to the technical field of microbes. Background technique [0002] Oleander hawkmoth (Daphnis nerii (Linnaeus)), also known as pink-green hawkmoth, hawkmoth, oleander hawkmoth, belongs to Lepidoptera (Lepidoptera), Sphingidae (Sphingidae), It is a worldwide pest and is distributed in Guangdong, Guangxi, Taiwan, Fujian, Jiangxi, Yunnan, Hunan and Sichuan provinces in China. The oleander hornworm mainly harms oleander, and also harms the medicinal plant Rauvdfiavomitoria Afzel.ExSpreng of the genus Rauvdfiasp., and other tree species in the family, as well as the soft branch yellow cicada and yellow oleander , periwinkle and other plants of the Apocynaceae family. [0003] Insect virus insecticide has strong specificity, and it not only has the common advantages of biological pesticides such as high insecticidal efficiency, strong selecti...

AI Technical Summary

Problems solved by technology

[0005] In actual use, it has been found that the above-mentioned strains only have a good killing effect on the oleander hornworm, but have a poor effect on the bean hornworm, and basically no application that has a good effect on other insects has been found.
