Problems solved by technology

However, the rubber stopper dispenser still seems labor-intensive and time-consuming in production and operation, because it must be formed by manual dripping one by one, and it is not suitable for the large-scale production of pheromone lure cores.
Moreover, the moth-attracting duration of the rubber stopper lure is shorter
The manufacturing process of other dispensers is relatively complicated, and the amount of pheromone used in most of them is relatively large, which leads to an increase in cost and is not suitable for the current situation in our country.

Embodiment 1

[0013] Embodiment 1. The control group adopts the commonly used silicone rubber stopper, and in the recess of the silicone rubber stopper, dropwise add 100 μ g 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 finished produc...

Embodiment 2

[0016] Embodiment 2. The control group adopts common silicon rubber stopper, adds dropwise the dichloromethane of 60 μ l containing corn borer sex pheromone 25 μ g (Z12-14: Ac / E12-14: Ac=1 / 1) 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 the silico...

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:Al / 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:

Abstract

The present invention relates to a distributor for distributing insect pheromone for monitoring and controlling insects. Said distributor is a circular silicone rubber ring. Said silicone rubber ring is soaked in the solution containing required insect pheromone to obtain the invented seduction core. As compared with silicon rubber plug seductino core made up by using dropping process said invented product can obtain more excellent moth-trapping effect, and its production process is simple and cost is low.

Description

technical field [0001] The invention relates to a biological control method, in particular to an insect pheromone lure dispenser and a preparation method thereof. Background technique [0002] Insect pheromone is a chemical communication substance that is secreted by the special glands of insect individuals and can affect the behavior, development and reproduction of other individuals of the same or different species. The use of insect pheromones to control pests is a new pest control technology developed since the 1960s. The use of insect pheromones to control pests is a new technology of integrated pest management, which has the advantages of economy, effectiveness, no environmental pollution, protection of natural enemies, convenient use, safety, and no resistance. At home and abroad, the research and application of insect pheromones are very important. The application of insect pheromones can be used for pest control in the aspects of pest monitoring, pest quarantine, ...
