Embodiment 1

[0011] Embodiment 1: the preparation method of fruit fly sex attractant slow-release agent, carry out as follows: dissolve 5 gram methyl eugenols and 10 gram trichlorfon in 100 gram acetones; 1kg molecular weight is the polybutadiene resin of 2800 Stir for 100 minutes at 35°C with a vacuum of -0.1MPa; mix the above two solutions, continue to stir until they are evenly mixed, then add 10kg of toluene diisocyanate and continue to stir for 120 minutes at 35°C with a vacuum of -0.1MPa. Stop vacuuming, obtain the fruit fly sex attractant slow-release agent of paste, make the capsule particle of 5g / again. Methyl eugenol and trichlorfon are wrapped in the polymer film of polyurethane produced by the reaction of polybutadiene resin and toluene diisocyanate. The effect of trapping and killing fruit flies can be achieved by putting the capsule particles into fruit fly lure bottles and hanging them in the field.

Embodiment 2

[0012] Embodiment 2: the preparation method of fruit fly sex attractant sustained-release agent, carry out as follows: dissolve 1 gram of muscarin and 0.1 gram emamectin in 100 gram of acetone; 1kg molecular weight is 2000 terminal hydroxyl poly Stir the ether resin at 75°C with a vacuum of -0.1MPa for 15 minutes; mix the above two solutions and continue to stir until they are evenly mixed, then add 5kg of cyclohexane diisocyanate and continue stirring at 75°C with a vacuum of -0.1MPa After 120 minutes, the vacuum was stopped to obtain the paste-like fruit fly attractant slow-release agent, which was then made into 5g / capsule granules. Muscarin and emamectin are wrapped in the polymer film of polyurethane produced by the reaction of hydroxyl-terminated polyether resin and cyclohexane diisocyanate. The effect of trapping and killing fruit flies can be achieved by putting the capsule particles into fruit fly lure bottles and hanging them in the field.

Embodiment 3

[0013] Embodiment 3: the preparation method of fruit fly sex attractant slow-release agent, carry out as follows: dissolve 50 gram methyl eugenol and 20 gram abamectin in 100 gram acetone; 1kg molecular weight is the hydroxyl-terminated polyester of 2900 Stir the resin at 50°C under a vacuum of -0.1MPa for 50 minutes; mix the above two solutions, continue to stir until they are evenly mixed, then add 3.33kg of polymerized cyclohexane diisocyanate and continue at 50°C under a vacuum of -0.1MPa Stir for 120 minutes, stop vacuuming, obtain the fruit fly sex attractant slow-release agent of paste, make the capsule particle of 5g / grain again. Methyl eugenol and abamectin are wrapped in a polymer film formed by the reaction of polybutadiene resin and polymerized cyclohexane diisocyanate. The effect of trapping and killing fruit flies can be achieved by putting the capsule particles into fruit fly lure bottles and hanging them in the field.

Abstract

The invention relates to a preparation method of a sexual attraction slow-release formulation for fruit flies. By weight parts, the preparation method comprises the following steps: (1) dissolving 1-50 parts of methyl eugenol or cue-lure and 0.1-20 parts of toxic ingredients in 100 parts of organic solvent, for standby application, wherein the toxic ingredients include trichlorphon, abamectin, and emamectin benzoate or chlopyrifos; (2) stirring 1000 parts of polyatomic alcohol with molecular weight smaller than 3000 for 15-100 minutes at the temperature of 35-75 DEG C and vacuum degree of minus 0.1MPa; and (3) adding the standby solution of the step (1) in the polyatomic alcohol of the step (2), continuing stirring to be uniform, then adding 3000-10000 parts of isocyanate, continuing stirring for 120 minutes at the temperature of 35-75 DEG C and vacuum degree of minus 0.1MPa, stopping vacuum-pumping, and then obtaining pasty sexual attraction slow-release formulation for the fruit flies. The sexual attraction slow-release formulation prepared by the method is mainly used for monitoring fruit fly population density or preventing and controlling fruit fly pests in large area.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a preparation method of a fruit fly sex attractant slow-release agent. Background technique [0002] Tephritid pests belong to the order Diptera and the family Tephritidae, and are an important class of pests that cause serious losses to fruit and vegetable crops. Tephritidae has so far known about 500 genera and more than 4,500 species. Among them, there are 15 genera, 22 subgenuses, and more than 150 species of fruit and vegetable harmful fruit flies. Flies, etc. are more common, mainly distributed in Hunan, Hubei, Sichuan, Chongqing, Guizhou, Fujian, Guangdong, Guangxi, Hainan, Yunnan, Taiwan and other provinces. The host range of harmful fruit flies is very wide, involving a total of 24 families and 42 genera of economic fruit plants; 4 families and 16 genera of vegetable plants (wild host plants are not included). Fruit fly pests have strong fecundity and great harm. In fruit fl...
