Description

A kind of colloid cockroach bait

technical field

The invention relates to a bait for insecticides, in particular to a bait for trapping and killing cockroaches.

Background technique

There are many insecticide-containing cockroach baits reported at present. In addition to various insecticides, they also contain carbohydrates such as honey, corn syrup, honey, fructose, sucrose, and animal and plant proteins such as silkworm chrysalis powder and soybean protein. , such as U.S. Patent No. 5,676,961, these ingredients are ingredients and feeding stimulants that cockroaches like to eat.

There are also some reports that add some furanone compounds, such as sotolone (3-hydroxyl 4,5-dimethyl-2 (5H)) furanone (Kamzaki et al. (1983), Nippon NogeikagakuKaishi 57 (7), 649-653; 656-658) and furaneol (4-hydroxy-2,5 dimethyl-3 (2H)) furaneol as cockroach attractants, but these compounds are more expensive.

Contents of the invention

Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a new colloidal cockroach bait, which has low cost, strong pertinence, good moisturizing performance and no pollution to the environment.

The purpose of the invention of the present invention is achieved through the following technical solutions:

A kind of colloid cockroach bait, its composition and proportioning are as follows:

Cockroach feeding stimulant 1-10%

Gelling agent 1.5-2%

Moisturizer 5-20%

Preservatives 0.25-0.3%

Carbohydrate food 1-15%

The balance is water

The above percentages are percentages by weight. The feeding stimulant for cockroaches is beef extract powder, the gelling agent is agar powder, the moisturizing agent is glycerin, and the preservative is methylparaben.

The cockroach insecticide can be prepared by mixing the prepared cockroach bait with the pesticide effective to the cockroach. The pesticide may be imidacloprid, sulfluramid, fipronil or hydramethynon, etc.

In the present invention, the main component feeds stimulant, that is, the beef extract powder has the effect of promoting cockroaches to feed, which can be illustrated by the following experiments:

Take a commercially available roll of toilet paper, fold it into 8 layers, and cut it into several pieces of 3.5×3.5CM squares with scissors. All the water-soluble samples to be tested are made into 10% solution with distilled water, drop 200 microliters on different papers, furanone is made into 10% solution with acetone, drop 200 microliters on paper, weigh 100 Milligram egg powder smeared on paper. Put all the papers containing the samples on the glass test paper of 75×75×40CM, place water, cockroach feed and a hiding device made of cardboard in the box, and put about 300 different kinds of cockroaches ( male and female adults and larvae).

At 16:30 every day, put three different samples into a test box at will, and take them out at 8:30 the next day. All the samples were tested at the same time, and each test box tested one kind of cockroach at a time, and tested three kinds of cockroaches in total: Periplaneta melanogaster, Blattella germanica, and Periplaneta americana.

Table 1

Note: The number 1 in Table 1 means that there are about 40-50 bite marks, and so on, the larger the number, the more bite marks.

As can be seen from the above Table 1 (test results of various samples), the paper containing beef extract powder has the most bite marks.

Then honey, fruit pulp and beef extract powder were compounded for testing. The test method was the same as that in Table 1, and the results were shown in Table 2.

Table 2

Note: The number 1 in Table 1 means that there are about 40-50 bite marks, and so on, the larger the number, the more bite marks.

As can be seen from the results in Table 1 and Table 2 above, the beef extract powder is the material that the three cockroaches like to eat most, and has the effect of stimulating feeding.

The cockroach bait of the present invention promotes the feeding of cockroaches due to the addition of the cockroach feeding stimulant beef extract powder, the addition of a moisturizing agent makes the bait not shrink for a long time, prolongs the use time, and the raw materials are easy to obtain, the price is low, No environmental pollution. Therefore the product of the present invention has advantages such as low cost, good effect of luring cockroaches, long service life, and environmental protection.
