Abstract

The invention provides a meadow moth and scarab attractant. The meadow moth and scarab attractant comprises, by weight, 25-30 parts of meadow moth sex hormone extracts, 15-20 parts of scarab sex hormone extracts, 25-30 parts of sunflower extract powder, 7-10 parts of pyrogallol, 5-7 parts of myricetin, 6-9 parts of quercetin, 12-15 parts of p-tert-butylphenyl salicylate, 20-30 parts of ethyl acetate and 5-8 parts of tebufenozide. The meadow moth and scarab attractant has the advantages that excellent meadow moth and scarab trapping and killing effects can be realized by the attractant, the meadow moth trapping quantity can reach 70-135 per trap within 20 days, and the scarab trapping quantity can reach 65-112 per trap within 20 days.

Description

technical field [0001] The invention provides a meadow borer and scarab attractant and a preparation method thereof, belonging to the field of pest control. Background technique [0002] Meadow borer is a migratory pest of crops and pastures in my country. It breaks out intermittently and is mainly distributed in Northeast, North and Northwest regions. Its occurrence is violent, dense and serious. In a major occurrence year, a large area of ​​crops and pastures can be destroyed in a short period of time, causing serious disasters. Scarabs are widely distributed in my country, and they are distributed to varying degrees in Northeast China, North China, and East China. The larvae of scarab beetles are called "grubs", and in some places they are also called "white ground silkworms". They harm crop seeds and tree roots, etc. Adults eat apples in large quantities , peach, pear, plum, chestnut, ginkgo, sunflower and other plant leaves, twigs, and fruits seriously affect plant grow...
