Fruit fly attractant concentrated solution and matched fruit fly attractant thereof

Abstract

The invention provides a fruit fly attractant concentrated solution and a matched fruit fly attractant thereof. The fruit fly attractant concentrated solution is prepared from, by weight, 0.1-10 parts of sweet orange oil, 0.1-12 parts of citral, 0.1-15 parts of glycerol ester of rosin, 0.1-10 parts of sucrose acetate isobutyrate, 0.1-8 parts of 4-p-carboxylphenyl-2-butanone, 3-70 parts of brown sugar, 0.1-5 parts of ethyl alcohol, 0.1-6 parts of acetic acid, 0.1-15 parts of ethyl acetate and 0.1-30 parts of protein hydrolysate. The fruit fly attractant concentrated solution has the advantages of increasing the attractant effect and improving the stability of applied liquid chemical.

Description

technical field [0001] The invention relates to the field of fruit tree pest control, in particular to a fruit fly attractant concentrate and a matching fruit fly attractant. Background technique [0002] Fruit flies are a major pest. In the existing control technology, the methods of fruit fly control include trapping by spraying, sticking and trapping by hanging bottles. [0003] Among them, the method of trapping and killing adults by spraying insecticides on Bactrocera is as follows: use 100 grams (2 taels) of 90% crystal trichlorfon + 3 catties of brown sugar + 100 catties of water during the adult period (middle and late May to early July) Prepare 500-800 times of liquid medicine, before the adults start to feed at 9 o'clock in the morning, the large mist is sprayed on the back of the citrus leaves with dense branches and leaves and more results in the citrus orchard. Spray 1 / 3 of the trees in the whole garden, spray 1 / 3 of the crown of each tree, change the directio...

AI Technical Summary

Problems solved by technology

At the same time, the liquid medicine should be prepared according to the standard, and the dosage of crystal trichlorfon should not be increased or decreased casually, so as not to reduce the trapping and killing effect.

[0005] The above-mentioned spraying method and the hanging pot method all have the following disadvantages: 1) crystal trichlorfon is used as a component in the above-mentioned method, although crystal trichlorfon has the effect of killing fruit flies, but it will become highly toxic in an alkaline environment. , so in the spray or hanging cans, care should be taken to prevent the liquid medicine from entering the mouth and prevent the liquid medicine from contacting the skin, which will cause trouble to the operation. At the same time, the stability of trichlorfon is poor in an alkaline environment, and Its stability is also not very good, so in the above-mentioned method all will change a medicinal liquid or spray a medicinal liquid again in 5 to 7 days, to make up for the shortcoming that it is very easy to fail; 2) all only adopt brown sugar as the lure in the above-mentioned operation To lure fruit flies, because the smell of citrus is quite different from that of citrus, after long-term use, fruit flies will distinguish it from citrus fruit, and the attracting effect will gradually weaken
