Description

Insect-paste

The present invention relates to a kind of medicine of killing sanitary insect pest, specifically a kind of medicine of killing various pests such as cockroach, ant, fly, termite.

Cockroach is a kind of spreading disease, serious harm people's lives and healthy a kind of sanitary insect pest, and it haunts about kitchen, dining room, food processing factory etc. and locates, and it relatively likes sweet, fragrant, the soft food of food, very troublesome.The deinsectization articles for use kind of killing cockroach on the market is a lot, and the method for various granules, tablet, propellant and some physics is arranged.Have his own strong points, but a kind of existing effect of luring preferably and killing is not arranged as yet, and the deinsectization articles for use that keep better effects are chronically arranged simultaneously.(USP 4,812,309-1989) disclose a kind of insect-paste prescription of killing cockroach, and Maxforce is a kind of colloid of killing cockroach that better stomach poison function is arranged, but this colloid in a short time will soon be dry and cracked, greatly reduces its allure for United States Patent (USP).

The purpose of this invention is to provide a kind of allure and poisoning power is strong, can make colloid keep long-term soft simultaneously again, surface wettability, thus make it that insect-paste agent prescription of longer residual effect and preparation method thereof be arranged.

Other has better stomach poison function to cockroach to the insecticide composition that the present invention proposes with the decis of 0.01-3% etc., but does not have the insecticide of food refusal effect, also can select other insecticide for use according to the requirement of killing different insects.Adding 2-20% gel, 20-30% water, 5-25% wetting agent, 10-20% attractant, 0.1-1% preservative and 0.1-1% antioxidant forms.Wherein gel is generally carboxymethyl cellulose and agar etc., and wetting agent is a glycerine, and attractant is dry powder, corn flour, analysis for soybean powder of sucrose, milk powder, dusty yeast, honey, maltose, beef extract and various animal visceras etc.Preservative is methyl p-hydroxybenzoate, propylparaben or sorbic acid etc.Antioxidant is BHT (2, the 6-2 tert-butyl group-4-methylphenol).

The preparation method is as follows:

In first container, the wetting agent that adds gel in the A component, water, attractant and 70% by weight percentage successively mixes heated and stirred, temperature remains on 80-100 ℃, treat that gel dissolves, each component fully mixes, and continues insulation under the 80-90 ℃ of condition.Preservative, antioxidant and remaining 30% softening agent with the B component in another container mix the back heating, and remain under the 70-90 ℃ of condition standby.Insecticide is joined in the A component, add the B component while stirring simultaneously, after waiting to stir, stop heating, and in stirring, make temperature reduce to room temperature rapidly.Be poured into while hot in the special mould, can change the denseness of its colloid according to different instructions for uses, increase the content of gel, can increase the denseness of colloid, otherwise reduce the consumption of gel, the consumption that increases wetting agent then can reduce the denseness of colloid, the polytype insect-paste of the suitable preparation of this program.

The present invention can be prepared into the insect-paste that matches with the cockroach feeding habit.Therefore, allure and poisoning power are strong, and have characteristics such as residual effect is lasting and not dry for a long time.Because wetting agent has used glycerine in the prescription, can keep moistening for a long time at normal temperatures, thereby extremely strong to the palatability of various cockroaches.Simultaneously and can keep this wet characteristic for a long time, a large amount of take in malicious glue and be detained in the deadly cockroach body a certain amount of insecticide is arranged, the habit that the similar corpse of ingesting is arranged because of cockroach, so after cockroach eats this corpse, also can be poisoned to death, this is referred to as chain effect, and the experiment of table one will further confirm positive effect of the present invention.
