Abstract

Manufacturing process of an insect attractant product. Starting from the use of trimethylamine and ammonium acetate, the procedure consists in obtaining two independent solutions of these two products, specifically a 0.5 / 5% trimethylamine solution, and a 10/30% ammonium acetate solution, then adding and also independently of each of these solutions a superabsorbent, such as polyacrylamide crystals, capable of absorbing 200 times its weight in water, until obtaining respective gels. Finally, both gels are mixed in equal parts and homogenized, giving rise to a final product from which the smells corresponding to trimethylamine and ammonium acetate are volatilized at the same time and in the right proportions to fulfill their attractive function for insects towards inside of the corresponding flycatcher.

Description

Product manufacturing procedure insect attractant

Object of the invention

The present invention relates to a method of manufacturing a product that can be used as an active insect attractant especially for the Mediterranean fruit fly " Ceratitis Capitata Wied ", although its use can be generalized to the scope of the diptera of the family " Tephritidae " . This procedure can be useful for conferring certain volatility characteristics to any substance that requires it.

The object of the invention is to include substances that are attractants for these insects in another substance (which acts as an absorbent) that gives it some characteristics that in themselves do not have, such as controlled volatility, or persistence With this you can mix several substances in a single preparation (separately these would react with each other canceling its characteristics), and allows its installation in the flycatchers and enables the capture and death of these insects.

Background of the invention

The economic importance of pests of frugivorous parasitic flies in the field of fruit and vegetable production is well known. The Ceratitis Capitata Wied stands out for its importance. commonly called Mediterranean fruit fly (medfly in English).

For the control and eradication of flies Frugivorous there are different procedures based on the use of insecticides and others, more ecological, which consists in attracting Fly a flycatcher and kill them there. In this way the insecticides do not apply to the leaves or fruits of fruit and vegetables with the consequent reduction of waste Toxic and benefit to the environment. The use of a good Attractant is essential for the application of this technique. The persistence over time is the other great asset to avoid continuous prescription of the flycatchers.

Fruit fly adults need sugar and proteins, which usually constitute the basis Fundamental of your food. The traps or flycatchers used to its capture consists of a receptacle that facilitates the entry of the flies, through the effluvium of the attractants that leave by the entrance holes, but that prevents its subsequent exit. These attractants simulate food effluvium (matter organic). It is also used occasionally and as a means of complementary attraction certain visual stimuli (color of the flycatchers) or sex pheromones.

One of the solutions adopted so far to obtain several attractive products for flies the fruit, consists of a combination of trimethylamine, acetate ammonium and putrescine packaged each separately (sachets Watertight polyethylene with a very difficult porous membrane handling), which occur when they are introduced inside the flycatcher to a combination of odors that attracts flies.

This solution brings with it a problem with a double slope, on the one hand the product is very high cost, with the consequent and negative impact that this brings I get for the farmers, and on the other hand the difficulty of install them inside the flycatchers. The putrescine that participating in it is a problematic product, for which it they suspect carcinogenic effects and that we eliminate, until the EU arranges its use without restrictions ...

Description of the invention

The procedure that the invention proposes solves the problem fully satisfactorily previously exposed, allowing the manufacture or obtaining of an attractive product of low cost, with optimal performance functional.

To do this and more specifically said procedure consists exclusively of using trimethylamine and ammonium acetate, in certain proportions and in some also specific conditions.

More specifically: from the trimethylamine a solution in water is obtained, with a percentage for the same between 0.5 and 5%, and to said solution a superabsorbent (polyacrylamide) is added, capable of absorbing 200 times its weight in water, finally getting a gel.

In parallel, another acetate solution is made ammonium in water, in this case with a proportion between 10 and 30% and also a super absorbent is added to it Get a second gel.

Then both gels are mixed and homogenize by staying in a suitable container. In these conditions both substances do not react with each other, on the contrary if they were mixed in a liquid state. In this way both smells, that is, those corresponding to one or another product, they are volatilized simultaneously, in the right proportions and for a long time,  because the gel form slows down considerably evaporation. Obviously in each flycatcher the amount will be available suitable of this combined gel.

The possibility that the gel of Ammonium acetate is replaced by two gels, one of acetic acid and another of ammonia, in which case the three gels will join in a gel-mix, as in the previous case, with the adequate proportions.

Example of practical embodiment of the invention

10 to 50 grams are deposited in a container of trimethylamine (equivalent to 1% to 5% by weight percent) and 990 to 950 milliliters of water (99% -95% percent by weight). This mixture is stirred until homogenization is achieved, and Next, 50 grams of product are added to the solution. superabsorbent, (polyacrylamide), stirring again until get a gel

In parallel, they are deposited between 100-300 grams of ammonium acetate (equivalent to 10% -30% both weight percent) and 900-700 milliliters of water (90% -70% percent by weight). This mixture stir until homogenization is achieved, and then provides 100 grams of superabsorbent product to said solution, (polyacrylamide), stirring again until a gel is obtained.

The two gels thus obtained are mixed in parts equal and homogenize, by stirring, for a time of 30 minutes.

The resulting gel thus obtained is packaged in Any suitable and airtight container. The use will be in units for each flycatcher, (plastic bags cut by their upper part) or in larger containers placed at the base of the flycatcher a certain amount of gel.

Claims (1)

1. Procedure for manufacturing an insect-attracting product, especially the Mediterranean fruit fly, Ceratitis capitata Wied , in which trimethylamine and ammonium acetate are essential components, a fact already known, but characterized in that trimethylamine, in a proportion between 0.5 and 5%, becomes an aqueous solution, by providing water up to 100%, and then to this solution a superabsorbent product, such as polyacrylamide crystals, capable of absorbing 200 times is provided its weight in water, until a gel is obtained. At the same time and in parallel with the ammonium acetate another solution is obtained, in this case with a proportion between 10 and 30%, ammonium acetate solution to which the same type of superabsorbent is also added, to achieve a second gel , having planned that both gels are subsequently mixed and homogenized, finally being packed with a hermetic closure until the moment of its use, where there is a simultaneous volatilization of trimethylamine and ammonium acetate, in appropriate proportions, slowed down by their state gel
