Abstract

The invention discloses preparation and use methods of a food attractant for scarab species. The preparation method of the food attractant includes the steps: firstly, collecting fresh elm leaves, grinding the collected fresh elm leaves in a grinder, and extracting with an extraction reagent at the room temperature prior to filtration, wherein a (v / w) ratio of the added extraction reagent to the ground raw material is 3:1; secondly, concentrating extract liquid prepared in the first step by a rotary evaporator; and thirdly, adding 4ml of extract concentrate obtained in the second step on absorbent cotton 2cm in diameter to prepare lures. The use method includes the steps: firstly, hanging the lures in collecting bags below scarab traps; secondly, placing the scarab traps in fields from 19:30 every night to the early morning of the next day; thirdly, during hanging, enabling the collecting bags below the scarab traps to be 2m-4m above the ground; and fourthly, for using time, starting from scarab wintering for imaginal emergence. Major components of the food attractant are from plants, and the food attractant is not in contact with crops when used, non-toxic, free of pollution and effective to main scarab species.

Description

[0001] The present invention is a divisional application for an invention patent with the application number 201110308667.4, the application date is October 13, 2011, and the invention name is a method for preparing and using a food attractant for beetle beetle pests. technical field [0002] The invention relates to a method for preparing and using a food attractant, in particular to a method for preparing and using a food attractant for beetle beetles. Background technique [0003] Scarab beetle is a common main soil-dwelling pest in agricultural and forestry production. Its larvae grubs harm many crops such as peanuts, soybeans, sweet potatoes, and corn, especially the three major scarabs: black beetle, aeruginosa and large black beetle. Due to its wide distribution, miscellaneous feeding habits, high concealment, and strong adaptability, control has always been the focus and difficulty of plant protection work, causing huge economic losses every year. Traditional control...
