A bionic flower capable of releasing fragrance and attracting insects at night or under dark conditions and preparation method thereof

Abstract

The invention provides a bionic flower capable of releasing fragrance and attracting insects at night or in the dark and a preparation method thereof. The bionic petal is made of a photosensitive material; an attracting core is placed on the bionic flower; the inner wall of the bionic petal is coated with armyworm Glue; the bionic petals are closed during the day, the curvature of the bionic petals becomes smaller at night or under dark conditions, and the bionic petals extend outward to release the lure. The biomimetic petals of the present invention are photosensitive materials, and because of their photosensitivity, the flowers are closed during the day, and the attractants are released at night or in a dark environment, so as to achieve the purpose of trapping pests and save the attractants.

Description

technical field [0001] The invention relates to a pest trapping tool and a preparation method thereof, in particular to a biomimetic flower that can release fragrance to attract insects at night or in the dark and a preparation method thereof. Background technique [0002] Spodoptera litura is a day-dwelling and nocturnal pest. Traditional agricultural control methods are cumbersome and require a lot of labor, while chemical control can lead to environmental pollution, so currently, it is more inclined to combine biological control and physical control. However, due to its biological habit, traditional biological control such as attractants is largely consumed during the day, resulting in unsatisfactory killing effects at night. Spodoptera litura has a strong phototaxis, and can be trapped and killed by black light at night, but it is a difficult problem to maintain the stability of the light source effectively in the field, and it is also relatively energy-intensive. How ...

AI Technical Summary

Problems solved by technology

Traditional agricultural control methods are cumbersome and require a lot of labor, while chemical control will cause environmental pollution, so the combination of biological control and physical control is more preferred at present

However, due to its biological characteristics, traditional biological control such as lures are consumed in a large amount during the day, resulting in unsatisfactory killing effect at night

Spodoptera litura has a strong phototaxis. At present, black light can be used to trap and kill at night. However, how to effectively maintain the stability of the light source in the field is a difficult problem, and it also consumes more energy.
