Description

A kind of fruit fly attractant

technical field

The invention relates to the field of pest control, in particular to a fruit fly trapping agent for fruits.

Background technique

At present, a major pest in the orchard is the fruit fly. The female fruit fly lays eggs on the mature fruit mast, and the hatched larvae grow by eating the fruit, which makes the surface of the damaged fruit uneven and the juice overflows, seriously affecting the quality of the fruit. yield, and the quality of the fruit deteriorates, affecting fresh sales, storage, processing and product prices. Although the traditional method of spraying the fruit surface with insecticides can remove pests including fruit flies, as the publication number is CN1322477 (2001-11-21) Patents, but most of the pesticides are chemical agents, the residues and residues cannot be well controlled, and they will damage the environment.

Contents of the invention

The purpose of the present invention is to solve the above problems, and provide a fruit fly attractant, which can confuse and lure fruit flies and kill them.

Above-mentioned technical purpose of the present invention is achieved through the following technical solutions:

A fruit fly attractant, characterized in that it comprises the following components and contents: fruit: 10-50 parts by weight, yeast: 1-10 parts by weight, vinegar: 1-7 parts by weight, sweet Agent: 2-6 parts by weight, insecticide: 1-3 parts by weight, water: 5-15 parts by weight;

Wherein the fruit includes the following types, and each fruit includes fresh and rotten ones and is mixed according to a mass ratio of 3/1. The fruit includes the following types and contents: grapes: 3-18 parts by weight, apples: 0- 12 parts by weight, banana: 0-12 parts by weight, bayberry: 5-22 parts by weight, pear: 0-5 parts by weight, peach: 0-5 parts by weight.

The present invention is through observation and experiment, finds that fruit fly adult is followed by red bayberry, grape, apple, banana, peach, pear to the order of strength and weakness of all kinds of fruit hobbies; Fruit fly larva is greater than peach, pear to red bayberry, grape, banana preference. And apples, aiming at this characteristic, the present invention utilizes fruit flies to the liking of fruit to make the trapping agent that lures fruit flies, this trapping agent is natural, does not affect the fragrance that fruit itself has, lures fruit flies sucking and sucking together with trapping agent, thereby Trapping occurs naturally without the fruit flies knowing.

Preferably, the sweetener is any one of sugar or honey or a mixture of two in any ratio. Smells are very attractive to fruit flies.

As preferably, the insecticide includes hormonal drugs or chemical drugs, hormonal drugs are only harmful to fruit flies, and do not pose a hazard to the environment and human life. If the chemical drugs are implemented in large quantities, they will have an impact on the environment. But its effect of trapping and killing fruit flies is remarkable.

Preferably, the hormonal drugs include juvenile hormones and sex pheromone analogs.

Juvenile hormone, also known as "rejuvenating hormone", is a hormone secreted by the pharyngeal body during the development of insects. In the larval stage, it can inhibit the appearance of adult characteristics, so that the larva remains in the larval state after moulting; in the adult stage , has the functions of controlling sexual development, producing sexual temptation, and promoting egg maturation. Spraying on insect larvae can increase the number of molting times of larvae; spraying on adult insects will cause infertility; spraying on eggs can prevent embryonic development and cause abnormal phenomena in various stages of insects, so it can be used to control pests.

Sex pheromone analogs refer to a hormone that attracts the opposite sex. By spraying or attracting, the sex ratio of fruit flies can be seriously imbalanced, and the birth rate of larvae can be reduced, so as to achieve the purpose of preventing and controlling pests.

As preferably, described juvenile hormone and sex pheromone analogue are carried out proportioning by 2/1, and content of sex pheromone analogue is less mainly in order to attract fruit flies of the same sex, and then it acts on it with juvenile hormone, and then Reduce the number of fruit flies and control the number of offspring.

Preferably, the chemical drugs include stomach poisons and contact killers. Stomach poison is a medicament that acts on the stomach and other digestive systems of pests to produce poisonous and lethal effects. Contact killers are medicaments that enter the body to destroy physiological functions by touching the epidermis of pests, or corrode the outer skin, resulting in the death of pests.

Preferably, any one of the stomach poison trichlorfon, diflubenzuron, imtabu, and Bacillus thuringiensis. Wherein the diflubenzuron enters the digestive tract of the pest, inhibits the synthesis of chitin of the pest, hinders the molting of the larvae, and causes the abnormal development of the worm body to death.

Preferably, the contact killer includes one or both of pyrethroids or mineral oil emulsions. Among them, the mineral oil emulsion can form a thin film on the surface of the pest, and close the valve to suffocate the pest to death.

Pyrethroid pesticides are a class of insecticides artificially synthesized by simulating natural pyrethrins, and the active ingredient is natural inulins. Because of its wide insecticidal spectrum, good effect, low residue and no accumulation effect, it has been widely used in the past 30 years. In addition to preventing and controlling agricultural pests, it has also achieved good results in controlling pests in vegetables and fruit trees; it also has a satisfactory killing effect on mosquitoes, cockroaches, head lice and other pests.

Preferably, the yeast is a food yeast, which is used to decompose fruit and make the fruit volatilize the smell that fruit flies like. Yeast is some single-celled fungi, not a unit of phylogenetic evolution classification, but a single-celled family of ascomycetes, basidiomycetes, etc. A general term for fungi, which can be used in brewing production, some are pathogenic bacteria, and are model organisms for genetic engineering and cell cycle research. Yeast is the earliest microorganism used in the history of human civilization, and can survive in an anoxic environment.

In summary, the present invention has the following beneficial effects:

The components required by the present invention are edible for humans except insecticides, non-toxic and harmless, simple to make, and the dose of insecticides is small, and the impact on the environment in the actual use of less toxic insecticides is almost Zero, but it has a fatal effect on trapping fruit flies.

Experimental data

experiment one

With the prepared traps of Examples 1-3 and Comparative Examples 1 and 2, get 5g respectively and pack them into the center of 5 identical petri dishes, put them evenly into the same square box, and put the square box Open it and place it indoors, take it out for observation after 6 hours, and find that most of the fruit flies are in the trap culture dishes of Examples 1-3, and only one or two fruit flies fall into the trap culture dishes of Comparative Examples 1 and 2.

From the above experiments, it can be known that the attractant effect of the attractants of Examples 1-3 on fruit flies is better than that of Comparative Examples 1 and 2.

Experiment 2

The experimental site is set in the orchard, a self-made trap is placed every 10m, and its weight is weighed, then the traps of embodiment 1-3 and the traps of comparative examples 1 and 2 get 100g respectively and put into the trap, Three decoys repeated three experiments to get the average value. Observe once at 24 hours, once at 48 hours, and once at 96 hours. During the observation, the fruit flies were cleaned and the traps were weighed. The observation results are as follows (the data is the average value of repeated experiments):

As can be seen from the above data, the trapping effect of the fruit fly trap of the present invention is far greater than that of the comparative example, and the fruit fly trap of the present invention can effectively lure and kill fruit flies, as long as a sufficient amount is added. , long duration of drug effect, which greatly solves the situation of fruit flies killing orchards, and also reduces manpower and material resources.
