Abstract

Disclosed is a biomimetic adhesive belonging to prevention and treatment of plant pest. The components and ratio of raw materials thereof are as follows: 25-50% of soft acrylic monomer, 1-5% of acrylic monomer, 0.1-0.3% of nonionic emulsifier, 0.1-0.8% of anionic emulsifier, 0.2-0.6% of catalyst, 0.1-0.3% of antiseptic, 0.02-0.05% of defoamer, and deionized water as remainder. Fluorescent substances or insect pheromones can also be added to said biomimetic adhesive. The biomimetic adhesive of the present invention has good effect of insect sticking without environmental impact, has long time effect, is safe, non-toxic and non-polluting, and can be sprayed directly onto the surface of plant branch and leaves using an ordinary sprayer due to its low viscosity at room temperature. It also has no adverse effects on photosynthesis and normal growth of plants. The preparation method of the biomimetic adhesive is also disclosed.
