Abstract

The invention discloses a mamestra brassicae nuclear polyhedrosis virus insecticidal mixture and an insecticidal synergistic method thereof. The mixture comprises a mamestra brassicae nuclear polyhedrosis virus preparation and is prepared by mixing the mamestra brassicae nuclear polyhedrosis virus preparation with parasitic nematodes serving as mediator organisms. Because the parasitic nematodes can actively find pests, invade pest bodies through various ways such as the oral cavity, the spiracle and the anus and parasitise in the pest bodies to cause numerous wounds, the virus infection timeis shortened, the probability of a mamestra brassicae nuclear polyhedrosis virus to infect the pests is increased, the lethal time of the pests is shortened, and the insecticidal efficiency of the mamestra brassicae nuclear polyhedrosis virus is improved.

Description

Technical field:

[0001] The invention belongs to the technical field of biological insecticide, and in particular relates to a virus insecticidal mixture and a preparation method thereof, in particular to a cabbage armyworm nucleopolyhedrosis virus insecticidal mixture and an insecticidal synergistic method thereof. Background technique:

[0002] At present, due to the impact of pests and diseases on a global scale, about one-third of the grain production is reduced every year; and in order to reduce the impact of pests and diseases on grain production, long-term, large-scale, and repeated use of chemical pesticides to kill crops However, due to the repeated use of a large number of chemical pesticides, on the one hand, the resistance of the pests has been caused, and on the other hand, due to the extensive use of chemical pesticides, it has a greater impact on the human living environment. Therefore, people begin to seek other methods and medicines for killing pests, such a...
