Abstract
The present invention adopts low methoxylation pectin with high content to coat cockroach alluring bait and insect killing medicine for poisoning and killing cockroaches. The low methoxylation pectin is gummed under certain conditions to form jelly colloid poison bait. After the jelly colloid poison bait is placed in a poisoning and killing position, the colloid shape of the jelly colloid poison bait can be still kept for a long time. The jelly colloid poison bait is suitable for the characteristic that cockroaches like gnawing and eating colloids, and favorable poisoning and killing effect is achieved. Besides, the jelly colloid poison bait can be suitable for poisoning and killing cockroaches in the common placement mode and a coating mode, and the jelly colloid poison bait is particularly suitable for implementing gap injection to achieve the purpose of alluring and killing cockroaches in a needle cylinder injection mode.
Description
Technical field
The present invention is applicable to that cockroach poisoning use the glue bait, is specially adapted in the needle cylinder injection mode, carries out the slit and injects the purpose of trapping and killing cockroach to reach.
Background technology
Cockroach is liked inhabiting among the slit, on the market catch roach box, cockroach room etc., only can eliminate the male cockroach that some come out to look for food from the habitat.As for female cockroach, if in the still habitats such as occuping slot, crack of hideing of cockroach (nymph) more; Even adopt the spray-type insecticide, it is limited to spray the dosage that enters slot inside, the poor effect of poisoning cockroach.The processing mode that these are traditional, that kills mostly is male cockroach, and female cockroach and if cockroach still survives, control efficiency is had a greatly reduced quality; Have only the female cockroach of elimination and could put out cockroach group completely as if cockroach.So, become cockroach prevention and cure new technology in vogue in recent years at female cockroach, if " slit injection " formula that the stealthy site of cockroach is handled is killed the roach method.This kind technology can be killed each worm phase of cockroach, especially female cockroach with if cockroach.
Prior art such as United States Patent (USP) 6,007,832 is described, is to present viscose shape colloid the initial stage, is placed in the sclerosis gradually later on of poisoning position, this skill then is to adopt the pectin of high level, gum deposit constitutes jelly shape colloid poison bait under certain condition, is placed in after the poisoning position, still keeps the colloid shape with the long time, be particularly suitable for the cockroach hobby and gnaw the characteristic of colloid, reach preferable toxic effect.
Summary of the invention
The present invention keeps luring of jelly shape to draw paste roach bait at the long period of utilizing low methoxyl pectin to make, add hypotoxicity, the roach medicament (insecticide) that kills safe in utilization again, be specially adapted to injection system, spot application is often haunted and latent my place in cockroach, as various slits, corner, hole, kitchen cabinet corner etc., as far as possible near nest or the movable place of cockroach, can keep to lure and draw and kill the long-lasting of cockroach.This gel can reach the depths, slit with the bait formulation spray, is located in gel sealing cockroach gateway at mark simultaneously, increases the chance of medicament contact cockroach, reaches the maximum cockroach effect of killing.Bait formulation and kill the roach medicament and under the colloid protection, can have the long time to keep the jelly shape, avoid moisture fast volatilization lose drug effect.This soft jelly formula colloid especially is fit to cockroach gnaws, and generally speaking, cockroach can be got food fully, can not stay surplus body, if any not got the food colloid, also can not stay the residue that is difficult to clean after stiff.
Pectin is 300-1000 galactonic acid (methylated ester ofpolygalacturonic acid) the long-chain structure for methyl-esterified, the pectin of general merchandiseization is extracted under slightly acidic condition by orange peel or pomace usually and gets, define according to FCC (Food Chemicals Codex): pectin methoxylation degree surpasses 50%, be called high methoxyl pectin (High Methoxyl Pectin, HMP); Be lower than 50%, then be called low methoxylated pectin (Low Methoxyl Pectin, LMP), these two kinds of pectin at room temperature all can be formed colloid, but the gum deposit condition has a great difference each other, HMP need be under the low pH-value of high solute could gum deposit; The gum deposit condition and range of LMP is then comparatively tolerant, and general pectin solute is 10% below more than 0.6%, pH 1.0-7.0, and adding divalent ion such as calcium ion are just can impel its gum deposit.Low methoxylated pectin gum deposit Ji Zhi Yes connects into bridge formation (bridge junction) with carbon oxygen base (carboxyl group) between the different galactonic acid long-chains and divalent ion, this zone easy dehydration crystallization of building bridge forms irregular colloid, the general bivalent verbal metal ion all has this to promote the gel ability to be called Alginates, and its short glue ability is magnesium ion (Mg in regular turn
