Embodiment 1

[0023] Embodiment 1: The disease-resistant insect was artificially fed with 0.1mM citrulline for 4 hours, then exposed to imidacloprid for 24 hours, and its survival rate was tested as follows: figure 1 shown.

Embodiment 2

[0024] Embodiment 2: The disease-resistant insect was artificially fed with 0.5mM citrulline for 4 hours, then exposed to imidacloprid for 24 hours, and its survival rate was tested as follows: figure 1 shown.

Embodiment 3

[0025] Embodiment 3: The disease-resistant insect was artificially fed with 1mM citrulline for 4 hours, then exposed to imidacloprid for 24 hours, and its survival rate was tested as follows: figure 1 shown.

Abstract

The invention provides a biological insecticide for control of brown rice planthopper. The biological insecticide comprises imidacloprid and water, and further comprises at least one of citrulline andarginine. The invention further provides a control method of brown rice planthopper, and the method includes the steps of: spraying the biological insecticide to rice plants, wherein the biological insecticide comprises imidacloprid and water, and at least one of citrulline and arginine. By adding exogenous arginine and citrulline, the activity of nitric oxide (NO) synthase in drug-resistant insects (brown rice planthopper) and the generation of nitric oxide can be increased, so that the activity of main detoxification cytochrome P450 is inhibited, and then the sensitivity of insects to imidacloprid is further increased.

Description

technical field [0001] The invention relates to a biological insecticide and a control method for controlling brown planthopper. Background technique [0002] Pests greatly reduce crop yield and quality. Their effects will increase in many areas of global warming. Insect damage is not only caused by a direct pest, but also caused by the indirect spread of plant diseases. To make matters worse, some insects, such as mosquitoes, fleas, lice and tsetse flies, are the main vectors of many diseases in humans and animals. At present, chemically synthesized insecticides are the main methods of pest control and biological vector control. However, their overuse has created a range of environmental and health concerns. To make matters worse, under strong selection pressure, pest populations can rapidly evolve species resistance. Worldwide, more than 550 species of insects and related arthropods have been reported to be resistant to more than 330 insecticides. [0003] The brown ...
