Abstract
The invention discloses an additive for reinforcing aggregation pheromone in rhynchophorus palmarum, which is prepared by mixing 20 to 70 weight parts of n-butyl alcohol and 30 to 80 weight parts of n-butyric acid. When used, the reinforcing additive is added into the pheromone in the rhynchophorus palmarum in a certain ratio. The additive can improve the quality of rhynchophorus palmarum pheromone and increase trapping rate. Meanwhile, the price of the additive is much lower than the original rhynchophorus palmarum pheromone, and product cost can be reduced.
Description
Technical field
The present invention relates to a kind of enhancing additive that can strengthen attractant effect added in the aggregation pheromone of coleopteron Asia palm weevil, belong to biological control of insect pests technology and external harmful biological invasion monitoring technical field.
Background technology
Asia palm weevil (Rhynchophorus ferrugineus/Fabricius) is the crushing insect of the multiple Perenniporia martius babassu of harm, the host be take babassu as main, comprises nearly 20 kinds of important ornamental plantss and the economic plants such as coconut, nipa palm, oil palm.In recent years, this Strategy of Alien Invasive Species is used in a large number along with babassu and allocation and transportation and rapid diffusion, the plantation area that spreads all over China's babassu, not only affect construction and the sustainable development of garden landscape, also limited the survival and development of foreign trade and the palm industry of palm plant.The extremely difficult monitoring of this external Invasive insect species and control, particularly because this worm endangers in tree body inside, disguised extremely strong, cause harm and be difficult in early days be found, be at death's door when manifest symptom appears in plant, rely on traditional conventional chemical control efficiency limited, and the height adopted poison persistent pesticide is to ecotope, cause great pollution, do not meet the sustainable development requirement.
Utilizing insect pheromone trapping Asia palm weevil is a kind of more satisfactory method of effectively preventing and treating, and does not contact plant while using, and burst size is extremely low, there is no the sorrow of pesticide pollution, has broad application prospects.The Asia palm weevil aggregation pheromone that can be directly used in regional Asia palm weevil adult insect density Supervise prevention and cure is abroad arranged at present, its principal component is 4-methyl-5-nonyl alcohol and 4-methyl-5 nonanone, there was same report in Oman in 2005, and ethyl acetate and mentioned component have been synthesized to a kind of independent bait Ferrolure+HP, but above external product all is difficult to apply at home because price comparison is high.
Insect pheromone is generally by multiple compounds mixing generation effect, and it is different with the effect of burst size generation that different proportion forms, and particularly in attractant, the composition of each component and ratio are the deciding factors of its attractive activity, is also the core technology in the attractant exploitation.Importantly, different topomorphic insect colony, to selectivity, the susceptibility of very strong pheromones fully likely produces different variations, and the synthetic product of bionic must be very approaching with the smell that insect in natural situation is accepted, otherwise just lacks competitiveness.Due to Asia palm weevil feeding habits complexity in natural environment, the Asia palm weevil aggregation pheromone composition used at home at present is comparatively simple, single attractant effect is limited and unstable, in the space that still is greatly improved of luring on success rate to targeted insect, this limitation also becomes the method as one of bottleneck of the conventional effectively means of prevention large-scale promotion in field.
Summary of the invention
The purpose of this invention is to provide a kind of enhancing additive improved the Asia palm weevil aggregation pheromone of the attractant effect of Asia palm weevil.
To achieve these goals, the present invention adopts following technical scheme:
The enhancing additive of Asia palm weevil aggregation pheromone, mixed by the n-butanol of 20-70 weight portion and the n-butyric acie of 30-80 weight portion.
The optimum amount of above-mentioned n-butanol is 70 weight portions, and the optimum amount of above-mentioned n-butyric acie is 30 weight portions.
After adopting such scheme, enhancing additive of the present invention has the material that in the main feeding plant of insect, insect is had strong sucking action, enhancing additive of the present invention is added in the palm weevil aggregation pheromone of existing Asia by a certain percentage, Asia palm weevil aggregation pheromone after making to add has dual attracting action to insect, improved the attractant effect of Asia palm weevil aggregation pheromone, improve the trapping success rate, the price of additive is low more than existing Asia palm weevil aggregation pheromone simultaneously, can save product cost etc.
Embodiment
The enhancing additive of Asia of the present invention palm weevil aggregation pheromone, evenly mixed by the n-butanol of 20-70 weight portion and the n-butyric acie of 30-80 weight portion.Wherein, the optimum amount of n-butanol is 70 weight portions, and the optimum amount of n-butyric acie is 30 weight portions.
Wherein: n-butanol (n-butanol; N-butyl alcohol; Butanol), molecular formula: CH
3cH
2cH

2cOOH, molecular weight: 88.10.
During use, the part by weight by the enhancing additive of Asia of the present invention palm weevil aggregation pheromone by 1:2-1 adds in the palm weevil aggregation pheromone of existing Asia, after evenly mixing, makes product.Enhancing additive of the present invention can improve the quality of Asia palm weevil aggregation pheromone, improves the trapping success rate, and the price of additive is low more than existing Asia palm weevil aggregation pheromone simultaneously, can save product cost etc.
This enhancing additive also can be made separately microcapsules, then adds in the palm weevil aggregation pheromone of existing Asia and make and lure core.These microcapsules can effectively increase and lure the lure rate of core to targeted insect, coordinate special-purpose trapper to use, can occur be monitored in early days at targeted insect, and in generation area for trapping and killing adult.
Below by concrete experimental data, effect of the present invention is verified.
1, laboratory test trapping result data:
Table 1 lures core (call the present invention in the following text and lure core) and existing Asia palm weevil aggregation pheromone to lure core (calling the former core that lures in the following text) to trap separately deck watch as a result for the Asia palm weevil aggregation pheromone that adds enhancing additive of the present invention:
| Decoy | Lure rate (%) |
| The former core that lures | 40 |
| The present invention lures core | 80 |
Table 1
Table 2 lures core (calling the former core that lures in the following text) competition trapping deck watch as a result for the Asia palm weevil aggregation pheromone that adds enhancing additive of the present invention lures core (call the present invention in the following text and lure core) and existing Asia palm weevil aggregation pheromone:
| Decoy | Lure rate (%) |
| The former core that lures | 20 |
| The present invention lures core | 50 |
Table 2
2, field trial trapping result data:
The enhancing additive of microcapsule formulations will be made after 70 weight portion n-butanols and the even mixing of 30 weight portion n-butyric acies, again the enhancing additive of this microcapsule formulations is added in the palm weevil aggregation pheromone of existing Asia by weight the ratio of 1:1, adsorb with cotton core again and be loaded in plastics microtubule or other release vehicles and make and lure core, control rate of release 3mg/ days, coordinate the funnel type trapper to use.The rate of luring in the controlled range of field is between 75-88%.
