Embodiment 1

[0012] The formula of this embodiment contains 72 parts of 1,2-dimethoxy-4-allylbenzene (ie methyl eugenol), 15 parts of dichlorvos, 11 parts of silicon dioxide, and 0.5 part of methyl cellulose. Weigh 11g of silicon dioxide and 0.5g of methyl cellulose, put them in a 1000mL beaker, add 15g of dichlorvos, add 72g of methyl eugenol while stirring, and pack it with a grouting machine.

Embodiment 2

[0014] The formula of this embodiment contains 75 parts of methyl eugenol, 13 parts of dichlorvos, 9 parts of silicon dioxide, 0.5 part of methyl cellulose and 0.5 part of sodium benzoate. Weigh 9g of silicon dioxide, 0.5g of methyl cellulose, and 0.5g of sodium benzoate, put them in a 1000mL beaker, add 13g of dichlorvos, add 75g of methyl eugenol while stirring, and pack with a grouting machine.

[0015] Squeeze 1g of the ointment into three lure bottles respectively, and drop 1mL of currently used liquid attractant (containing 1.00g of methyl eugenol) into the other three lure bottles respectively, and place two groups of lure bottles in insect-catching places. The effect comparison is shown in Table 1:

[0016] dosage form

Embodiment 3

[0018] The formula of this embodiment contains 80 parts of methyl eugenol, 11 parts of malathion and 7 parts of silicon dioxide. Weigh 7g of silicon dioxide, put it in a 1000mL beaker, add 11g of malathion, add 80g of methyl eugenol while stirring, and pack it with a grouting machine.

Abstract

The present invention relates to one kind of delayed releasing citrus fruit fly attractant and the attractant consists of methyl eugenol as attracting component and toxic pesticide as well as silica with excellent delayed releasing effect and preferably methyl cellulose and sodium benzoate as delayed releasing synergist and stabilizer. The present invention has the advantages of high stability, lasting effect, convenient use and easy control.

Description

technical field [0001] The invention relates to a sustained-release attractant for Bactrocera dorsalis. Background technique [0002] At present, the attractants used to prevent and control Bactrocera dorsalis are all to directly use industrial product methyl clove oil, add a certain amount of poison, and drop in the lure bottle to trap and kill. Its disadvantages are that it volatilizes too quickly and is variable during use, resulting in unstable trapping effect, large dosage and labor intensity (dosing needs to be added once every one to two weeks), and short trapping validity period (two weeks). Contents of the invention [0003] The purpose of the present invention is to develop a kind of attractant with high stability and high persistent effect to control Bactrocera dorsalis. [0004] The present invention adds silicon dioxide with good slow-release effect as the main filling material to the existing main attractant component methyl eugenol and poisonous component o...
