Abstract
The utility model provides a lure of aggregation pheromone for red palm weevils, which is composed of a plastic microtube with a unilateral opening, a cotton core and aggregation pheromone microcapsules for the red palm weevils. The plastic microtube is provided with the opening which ranges from 1 mm to 10 mm in size, and contains the cotton core which absorbs the aggregation pheromone microcapsules for the red palm weevils. Release speed of the pheromone can be controlled within the range from 5 mg/per day to 20 mg/per day by controlling the size of the opening, and according to the actual demand for the amount, the lure with a proper length is used with a trapper and then can be used for trapping and killing the red palm weevils. The lure of aggregation pheromone for the red palm weevils has the advantages of long durability, low in manufacturing cost and convenience in use, and the like, and is suitable for being widely popularized and utilized.
Description
Affiliated technical field:
The utility model relates to a kind of insect pheromone and lures core, is specifically related to a kind of red plam weevil aggregation pheromone and lures core, belongs to the biological control of insect pests technical field.
Background technology:
The red plam weevil that the utility model relates to (Rhychophorus ferrugineus/Fabricius) is that coconut palm is destroyed insect, it also is the importance insect of other multiple babassus, mainly cause harm with larva moth food trunk and tree crown lobus cardiacus, usually all be to invade by the injury or the crack of trunk, can also invade the tree body from the root that is positioned at the face of land, the plant surface that is injured looks excellent, but it is all destroyed to set the bar interior tissue in fact, usually just can cause cocoanut tree death in 5-6 month, the main host plants seeds have betel nut, oil palm, beautiful pin certain herbaceous plants with big flowers, the triangle coconut, nipa palm, bottle coconut etc.
Prevent and treat the method for red plam weevil insect pest at present, mainly taking early prevention is main method for integrated control, use guard in the trees seedling phase, can prevent the harm of red plam weevil, it is completely cut off with the tree that is injured makes it avoid infringement, and the trees more serious to early stage harm, dissectible carries out after chemical agent handles, again with on the intensive guard in case the adult that may survive escape.And the chemical agent control is considered to prevent comparatively effectively means of red plam weevil diffusion and control harm, but the chemical control destructible ecosystem and contaminated environment, the Biocidal technology of employing based on nematode, fungi, virus, bacterium etc. also arranged in recent years, but there is the bio-safety problem equally, and utilize red plam weevil aggregation pheromone trapping red plam weevil promptly not contact plant and agricultural product, the sorrow that does not also have residue of pesticide is one of prefered method of modern agriculture bionomic control insect.
Yet in the application process of pheromones, rate of release and burst size can have influence on effect, therefore, select the suitable core that lures just to seem particularly important.At present, in the research and application of insect pheromone, the various delayed release devices that comprise pheromones occur and promptly lured core, simply there is the rubber that adopts the cotton core dip in pheromones, in pheromones solution, soaked first-class, but its volatilization is fast, persistence is poor: complicated as " a kind of isotropic insect pheromone delayed release device of using " (applications/patents number: 200920000473.6), form by some plastic tubes, sealed at both ends and interconnect, pheromones is housed in the pipe, and wherein has the root plastic tube to be installed with iron wire; " a kind of ips typographus class aggregation pheromone delayed release device " (applications/patents number: 200920000472.1), by be equipped with aggregation pheromone absorption sheet and tubular slowly-releasing film transparent, have rectangular plastic bag (white or black) formation that hangs aperture; " a kind of insect pheromone lures the vaporizer of core " (applications/patents number: 02111474.9), by the annular silicon rubber loop of certain specification through twice immersion (soak time was respectively 8 hours and 10 hours) in the pheromones solvent, after volatilization naturally, promptly make again and lure core.But do not retrieve patent and report that any relevant red plam weevil aggregation pheromone lures core so far.
Therefore, can obtain optimum efficiency in order to use red plam weevil aggregation pheromone insect-killing trapping, Development and Production goes out a kind of suitable red plam weevil aggregation pheromone, and to lure core be technical problem to be solved in the utility model.
Summary of the invention:
The utility model provides a kind of red plam weevil aggregation pheromone to lure core, is used for red plam weevil insect pest monitoring and trapping.
The utility model is achieved in that on plastics microtubule tube wall cuts a monolateral opening along bearing of trend, its size is controlled between the 1-10mm, with cotton core absorption red plam weevil aggregation pheromone microcapsules, and be loaded in the plastics microtubule of monolateral opening, between 1-10mm, the corresponding pheromones rate of release of controlled is 2-10mg/ days by control opening size size.
Good effect of the present utility model is: lure that core production process is simple, production cost is low, the lasting period is long, can measure usefulness according to actual needs, by the specification size of control plastics microtubule opening, the controlled rate of release is 2-10mg/ days, obtains best control efficiency.And this aggregation pheromone attractant is to form according to the artificial proportioning of bionics principle, physics and chemical attribute are equivalent to natural VOC under the normal temperature and pressure, belong to the biological control technology, compare with the chemical control of routine, have nontoxic, pollution-free, efficient, selectivity is strong, characteristics to agricultural product, environment and natural enemies security, to the characteristics of agricultural product, environment and natural enemies security, easy to use, control efficiency is good, and compare imported product and have cost advantage, application suits large area to popularize.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Wherein: 1, plastics microtubule, 2, opening, 3, cotton core, 4, red plam weevil aggregation pheromone microcapsules.
Embodiment:
For the ease of understanding the utility model, provide specific embodiment below in conjunction with description of drawings, the present invention is further set forth explanation.Its effect is understood that it is to further concrete elaboration the of the present invention, and is not that the present invention is constituted any type of restriction.
On the tube wall of plastics microtubule 1, cut a monolateral opening 2 along bearing of trend, opening 2 sizes are controlled between the 1-10mm, with cotton core 3 absorption red plam weevil aggregation pheromone microcapsules 4, and be loaded in the plastics microtubule 1 that has monolateral opening 2, between 1-10mm, the corresponding pheromones rate of release of controlled is 2-10mg/ days by control opening 2 sizes.Only need the amount size according to actual needs during use, that gets appropriate length lures core (general 5-8cm), cooperates various trappers to use, and can be used to trap and kill red plam weevil or monitoring population dynamic in red plam weevil emergence period and generation area.
Claims (2)
1. a red plam weevil aggregation pheromone lures core, it is characterized in that this lures core to be made up of plastics microtubule, cotton core, red plam weevil aggregation pheromone microcapsules, and the plastics microtubule comprises cotton core, and cotton core is adsorbed with red plam weevil aggregation pheromone microcapsules.
2. the core that lures according to claim 1, its feature are that also it is the monolateral opening of 1-10mm that the plastics microtubule has an openings of sizes.
