Abstract
The invention relates to the field of pesticides, in particular to an insecticide composition for shielding and protecting bees. The insecticide composition comprises neem oil and a neonicotinoid insecticide component, wherein the mass ratio of the neem oil to the neonicotinoid insecticide component is 0.1-20: 0.5-50, and the neonicotinoid insecticide component is thiacloprid. The neem oil is vegetable oil obtained by mechanical cold pressing of neem kernels, and has repellent effect on various pests and bees. A compound preparation of the neem oil and the neonicotinoid insecticide is prepared, the nimbin oil is used for marking flowers which are applied with the compound preparation, or applied with the compound preparation mistakenly or subjected to drift treatment with the compound preparation, an effect of shielding and protecting the bees can be achieved by repelling the bees, and therefore, the neonicotinoid insecticide has low toxicity or even no toxicity to the bees. By reasonable regulation and control of the ratio of the neem oil to the thiacloprid, a bee protecting effect can be improved while an insecticidal effect can be ensured.
Description
technical field [0001] The invention relates to the field of pesticides, in particular to an insecticide composition for shielding and protecting bees and a preparation thereof. Background technique [0002] In recent years, bees have become non-target victims of pesticides, especially insecticides, and a large number of bees have disappeared in many countries and regions. Since the beginning of the 21st century, the number of bees in Europe has decreased by 10-30%, in the United States by 30%, and in the Middle East by 85%. Canada, India, Brazil, and Taiwan have also seen similar phenomena. . 68% of flowering plants in the world are pollinated by bees. Without bee pollination, about 40,000 species of plants will have difficulty in breeding. Among the 1300 kinds of crops, 70% are pollinated by bees. If the number of bees is insufficient, it will directly affect the yield and survival of crops. According to a research report published by EASAC, the EU research network, the...
