Abstract

The invention discloses a phyllotreta striolata insect trapping core, which is prepared from the following raw materials in parts by weight: 20 to 30 parts of rose essential oil, 5 to 9 parts of full-spectrum rare earth blue powder, 3 to 6 parts of chitosan coated cyclodextrin, 1 to 5 parts of graphene additives, 1 to 4 parts of talcum powder, 1 to 5 parts of dispersing agents and 10 to 20 parts of ethyl alcohol. According to the insect trapping core, the rose essential oil is adopted as a main agent and is matched with the chitosan coated cyclodextrin, the graphene additive and other raw materials, the slow release effect can be achieved, the rose essential oil is continuously released, long-term insect trapping can be conducted, then the insect trapping efficiency can be greatly improved, and the use efficiency of the product is improved.

Description

technical field [0001] The invention relates to the technical field of the flea beetle baiting core technical field, in particular to a baiting beetle baiting core and a preparation method thereof. Background technique [0002] Flea beetle belongs to Coleoptera and leaf beetle pests, commonly known as dog lice, flea beetle, or flea beetle for short. Mainly vegetables, but also harmful to solanaceous fruits, melons, beans and vegetables; the adult body is about 2 mm long, oblong, black and shiny, with many engraved points on the pronotum and elytra, arranged in longitudinal rows . There is a yellow vertical strip in the center of the elytra, both ends are large, the middle is narrow and curved, and the hind legs are enlarged and good at jumping. The eggs are about 0.3 mm long, oval in shape, pale yellow when first laid, and later become milky white. Larvae Mature larvae are 4 mm long, cylindrical in shape, slightly thin at the tail, light brown on the head, pronotum, and y...
