Parasitic wasp attractant and preparation method and application thereof

Abstract

The invention relates to a parasitic wasp attractant and a preparation method and application thereof. The parasitic wasp attractant comprises the following raw materials in percentage by weight: 0.02%-5% of linalool, 0.1%-10% of eugenol, 0.05%-5% of anethole, 0.1%-5% of benzyl propionate, 0.01%-1% of methyl 2-methoxybenzoate, 2%-7% of carrageenin and the balance being water. The parasitic wasp attractant disclosed by the invention can be effectively used for attracting scoliid adults to seek a nectar source for feeding and oviposition by virtue of the aromatic odor of an aromatic compound, thereby enhancing the parasitic rate of scoliids on grubs effectively; the parasitic wasp attractant disclosed by the invention can be used for controlling the quantity of the grubs by utilizing the natural enemies, scoliids, of the grubs, thereby greatly reducing the field dosage of a chemical insecticide, alleviating the environment pollution and enhancing the quality of agricultural products compared with a traditional chemical agent for prevention and control of grubs.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a parasitic wasp attractant and its application. Background technique [0002] Underground pests are an important class of pests in my country's agricultural and forestry production. There are more than 320 known species of underground pests, but grubs are the most serious and widely occurring, accounting for 80.5% of the number of underground pests. According to statistics, the damage caused by underground pests such as grubs generally leads to a 20% to 40% reduction in production, and a serious reduction in production by 70% to 80%, or even no harvest. , an important factor in quality and efficiency. [0003] For a long time, in order to ensure food production, a set of comprehensive prevention and control technology system based on chemical control measures such as chemical seed dressing and soil treatment has been formed. Since most of the pesticides used are long-term ...

AI Technical Summary

Problems solved by technology

Pesticide treatment of soil is a routine chemical control measure to reduce the insect population base in the field and control the damage caused by underground pests, but it is necessary to use insecticides with a long residual period. Insecticides such as BCH, which were commonly used in the past, have been banned due to their long residual period and serious residues. In the past 10 years, in line with the general trend of environmental protection, most of the new pesticides introduced to the market are high-efficiency and low-residue pesticides. There are very few pesticides that have obvious control effects on underground pests and are low in toxicity. Farmers want to control underground pests. Harmful, had to use highly toxic pesticides in violation of regulations, underground pest control has become the biggest obstacle to the production of pollution-free agricultural products
