Embodiment 1

[0025] On July 20, 2014, hibiscus aphids were selected as experimental materials, and 500 healthy aphids were picked to isolate the plants. With 10g of the powder of the present invention, 10g of the liquid is diluted with water to obtain 1000 times of liquid, and the present invention is used once every two weeks. Experimental results: One month later, there were no ants on the young branches and leaves of hibiscus, and the number of aphids was significantly reduced to 24; the growth of hibiscus was observed to be normal; the death rate of aphids was 95.2%.

Embodiment 2

[0027] On July 16, 2014, Photinia fruticosa aphid was selected as the experimental material, and 500 healthy aphids were selected to isolate the plants. With 10g of the powder of the present invention, 10g of the liquid is diluted with water to obtain 1000 times of liquid, and the present invention is used once every two weeks. Experimental results: One month later, there were no ants on the young branches and leaves of Photinia fragrans, and the number of aphids was significantly reduced to 21; the growth of Photinia fragrans was observed to be normal; the mortality rate of aphids was 95.8%.

Embodiment 3

[0029] On July 22, 2014, crape myrtle aphids were selected as experimental materials, and 500 healthy aphids were picked to isolate the plants. With 10g of the powder of the present invention, 10g of the liquid is diluted with water to obtain 1000 times of liquid, and the present invention is used once every two weeks. Experimental results: One month later, there were no ants on the young twigs and leaves of Lagerstroemia indica, and the number of aphids was significantly reduced to 26; the growth of Lagerstroemia indica was normal; the mortality rate of aphids was 94.8%.

Abstract

The invention belongs to the technical field of biology, and particularly relates to a biological pesticide for killing aphids and a preparation method for the biological pesticide. The biological pesticide comprises the main components of nontoxic and harmless cinnamomum camphora steam and leaf extract (camphor), plant ash leachate, beauveria bassiana, metarrhizium anisopliae, yeasts and glucose, so that insecticidal effects of the biological pesticide are greatly improved, and organic nutrients are provided for plants to promote the growth of the plants. The application of the biological pesticide is relatively specific, and the biological pesticide is mainly used for damage caused by aphids to various plants, and also has unobvious prevention and control effects on other insect damage. The biological pesticide has the characteristics of nontoxicity, high efficiency, no contamination, no pollution and no residues, is an important means for realizing green ecology, and has broad development prospect.

Description

technical field [0001] The invention belongs to the field of biological technology, and in particular relates to a biological pesticide for killing aphids and a preparation method. Background technique [0002] There are many kinds of aphids. There are more than 4,700 known species in the world, and there are about 1,100 species in China. Its reproductive ability is extremely strong, and it can reproduce 20-30 generations per year, and the number of reproductions per generation is huge. As a large agricultural country, China is also widely attacked by aphids. However, with the development of the agricultural industry, people urgently hope for green consumption, especially the stricter requirements for primary industries such as fruits and vegetables. It is precisely because there are many types of aphids that there are many types of vegetation that are harmed. At present, the country implements Green China, which of course also includes urban greening. However, aphids are...
