Embodiment 1
[0013] Embodiment 1. The control group adopts a commonly used silicone rubber stopper, and is added dropwise at the recess of the silicone rubber stopper containing 100 μg of beet armyworm sex pheromone (Z9, E12-14: Ac / Z9-14: OH=9 / 1). 60 μl of dichloromethane solution. Silicone rubber ring (thickness 1.5mm, height 4mm, inner diameter 3mm, outer diameter 6mm), take a container and put it into the silicon rubber ring, add the beet armyworm pheromone solution with a concentration of 0.30μg / μl to a level 3- 4cm, stir evenly, cover, soak for 8 hours, then stir the silicone rubber ring in the container once, soak for another 10 hours, open the container cover, volatilize naturally, remove excess solvent, and then make lures (100μg / lure) , the lure made in Shanghai Songjiang cauliflower field (2000.8.16-9.20) for field tests. The setting of the trap: the trap bracket used in the test is a thick bamboo pole with a diameter of 2-3cm. The trapping pots are all purchased from market fi...
Embodiment 2
[0016] Embodiment 2. The control group adopts common silicon rubber stopper, and the dichloromethane of 60 μ l that contains corn borer sex pheromone 25 μ g (Z12-14: Ac / E12-14: Ac=1 / 1) is added dropwise in the recess of rubber stopper solution. Silicone rubber ring lure (thick 2mm, high 3mm, inner diameter 4mm, outer diameter 8mm, 25 μ g / lure) is to use corn borer sex pheromone component (Z12-14: Ac / E12-14: Ac=1 / 1) , soaked in a dichloromethane solution with a concentration of 0.15 μg / μl. (soaking method is as embodiment 1) the lure core made is done field test in the corn field of Gaoling, Shaanxi, (the setting of trap is as embodiment 1) result is as follows:
[0017] lure
[0018] From the experimental results in Table 3., the moth-attracting effect of the corn borer sex pheromone silicone rubber ring lure is obviously better than that of the silicone rubber stopper lure. As can be seen from Figure 3, the silicone rubber plug lure failed after September 2, while...
Embodiment 3
[0019] Embodiment 3. The control group adopts ordinary silicone rubber stoppers, and in the recess of the rubber stoppers, 50 μg of diamondback moth sex pheromone (Z11-16:Ac / Z11-16:A1 / Z11-16:OH=5:5: 1) 50 μl of dichloromethane solution. Sex pheromone component (Z11-16:Ac / Z11-16:Al / Z11-16:OH =5:5:1) by immersing in dichloromethane solution with a concentration of 0.12 μg / μl (method as in Example 1). The lure core that will make is done field test in the Chinese cabbage field of Shanghai Baoshan, (the setting of trap is as embodiment 1) result is as follows:
