Sex attractant trapping and killing of pests is a green prevention and control technology advocated by the state in recent years. The principle is to release some chemical components called sex pheromone after sexual maturation by synthetic female moths to attract male orchards of the same species seeking mating. The trapping and killing of the trap in the trap causes the female to lose the chance of mating, and cannot effectively breed offspring and reduce the population of the offspring to achieve the purpose of prevention and control. Advantages of sexual attractants 1 High selectivity, each insect requires a unique formula and concentration, a high degree of specificity, no attraction to other insect species; 2 no drug resistance problems; 3 environmental safety, not Pollution, 100% compatibility with other control technologies; 4 Significantly improve the quality of agricultural products. Sex attractant application strategy 1 Begin to use when the density of insect population is low in the early stage of pests (ie, begin to use when overwintering adult pests of vegetable pests such as Spodoptera litura, Spodoptera exigua, and Plutella xylostella); 2 The treatment area should be greater than The moving range of pests is reduced to reduce the re-invasion of mature females and reduced in combination with other control methods, so as to exert the effect of comprehensive prevention and control. Use of sexual attractants According to the occurrence of orchard pests, special attractants and traps are set. For example, Ningbo Newcom sex attractants are applied to vegetables, and a special trap of Spodoptera litura is generally set for each mu. Place 1 trap of Spodoptera litura in the trap; set 1 trap for each beet armyworm per 1 to 2 acres; place 1 attractant per trap; set 3 to 5 Plutella xylostella per acre. For lures, use a paper glue or water basin as a trap (keep the water level to a distance of 1 cm from the lure). The bottom of special insect traps such as Spodoptera litura, Spodoptera exigua, etc. are 20-30 cm from the top of the crop. The bottom of the diamondback moth trap should be close to the top of the crop, 10 cm from the top. The sexual attractant is applied to fruit trees, and the height of the suspension is required to be about 1.5 meters from the ground, with 2 to 3 lures per mu. Note 1 due to the high sensitivity of sex attractants, installation of different kinds of insect traps, you need to wash your hands, so as not to pollution; 2 in general, replace the lures around the next month or so; 3 timely removal of dead insect traps, and Must not be poured around the field, need to be buried; 4 traps can be reused.
