Abstract
The invention discloses a kind of killing red ants bait formulation, including insecticidal constituent, preservative, phagostimulant and water, also include the inclusion agents of insecticidal constituent described in inclusion. This bait formulation adopts inclusion agents inclusion insecticidal constituent, it is possible to speed sent out by the degradation speed and the poison that slow down insecticidal constituent, and red fire ant is slowly poisoned to death after taking food, and eliminates the red fire ant not the taken food warning to this bait formulation, thus large area killing red ants; Insecticidal constituent in this bait formulation is higher than red fire ant lethal dose, and killing effect is notable.
Description
Technical field
The present invention relates to parasite killing bait formulation technical field, especially a kind of killing red ants bait formulation.
Background technology
Red fire ant, is subordinate to Hymenoptera: Formicidae insecticide, and health is brownish red, and build is bigger than general Formica fusca, becomes polypide length 3 millimeters��6 millimeters. Red fire ant is one of biological invasion with destructive power most that World Conservation Union includes, and the mankind and animals and plants are had huge lethality. Red fire ant is derived from South America, and in the incoming U.S. thirties in 20th century, and in spreading to Australia and Taiwan from the U.S. by cabinet case and turf at the beginning of 21 century, then further through household refuse from Taiwan Wuchuan City of incoming Chinese Guangdong province again, then spread to other cities and Hong Kong, Macao inside the province.
Red fire ant strong adaptability, feeding habits are assorted, have stronger reproductive capacity and aggressivity, and new incoming area can be broken out in a short time and cause disaster. The harm that red fire ant produces mainly has: one is harm agricultural production security, and red fire ant takes food the seed of crop, fruit, plumelet and root system, destroys the normal growth of plant, causes crops Severe Reduction even to have no harvest; Two is that red fire ant stings and stings people and animals, after human body is bitten by red fire ant, often can just like fire burn as pain, there will be thereafter blister, it is even dead that minority allergic human population also can produce anaphylactic shock; Three is destroy communal facility, and red fire ant is often built ant nest in the equipment such as electrical equipment, causes wire short-circuiting or facility failure. Therefore, the preventing and treating of red fire ant is always up the key subjects of international concern.
At present, main employing chemistry bait formulation preventing and treating red fire ant both at home and abroad, existing chemistry bait formulation is mainly prepared from by insecticidal constituent, attractant, bait, preservative etc., its preventing and treating red fire ant effect is better, but there is also obvious shortcoming: insecticidal constituent is degraded too fast in nature on the one hand, once insecticidal constituent is lower than lethal dose in bait formulation, not only can not kill red fire ant, become a kind of food on the contrary; On the other hand, insecticidal constituent is scattered in food, and red fire ant produces poisoning symptom immediately after taking food, and the red fire ant not taken food can be produced warning signal, and can not large area killing red ants. Between above two reason, existing bait formulation is difficult to thorough killing red ants, causes the wasting of resources and contaminated environment, and cost accounting is high.
Summary of the invention
It is an object of the invention to provide a kind of killing red ants bait formulation, this bait formulation can solve the problem that the insecticidal constituent degraded in existing killing red ants bait formulation is too fast and is difficult to large area killing red ants.
In order to solve the problems referred to above, the technical solution used in the present invention is:
A kind of killing red ants bait formulation, including insecticidal constituent, preservative, phagostimulant and water, also includes the inclusion agents of insecticidal constituent described in inclusion; Described insecticidal constituent is ethiprole or sulfluramid; Wherein, described ethiprole is the 0.05%��0.2% of described killing red ants bait formulation gross weight, and described sulfluramid is the 0.5%��2.0% of described killing red ants bait formulation gross weight.
In technique scheme, technical scheme is it may also is that described inclusion agents is ethyl cellulose or cyclodextrin more specifically; Wherein, described ethyl cellulose or cyclodextrin are the 0.1%��1.0% of described killing red ants bait formulation gross weight.
Further, described preservative is Nipagin complex esters; Wherein, described Nipagin complex esters is the 0.2%��0.5% of described killing red ants bait formulation gross weight.
Further, described phagostimulant includes tapioca starch, brown sugar and cracker meal; Wherein, 50%��60%, 10%��20% and the 10%��20% of described tapioca starch, brown sugar and cracker meal respectively described killing red ants bait formulation gross weight.
Described ethiprole is a kind of phenyl pyrazoles insecticidal constituent, to insect based on stomach poison function, having concurrently and tag and certain systemic action, its mechanism of action is in that the chloride metabolism hindering insecticide ��-aminobutyric acid to control, to crop without poisoning, there is higher safety.
Described sulfluramid is novel chronic Organic fluoride insecticidal constituent, good disinsection effect, and its mechanism of action is the energy metabolism suppressing insect, because this product active constituent content is low, mammal is safer, and dosage is few, the less pollution to environment.
The mechanism of described ethyl cellulose inclusion medicine is: be dissolved in organic solvent by ethyl cellulose; owing to ethyl cellulose molecule has mesh skeleton structure; when in medicine dissolution to the organic solution of ethyl cellulose; medicine enters in mesh skeleton structure with molecular conformation; then organic solvent is evaporated; medicine is wrapped in ethyl cellulose mesh skeleton structure with molecule or crystallite form; namely obtaining ethyl cellulose clathrate can protect medicine to exempt from destruction; delay the degradation speed of medicine, increase the curative effect of medicine.
The mechanism of described cyclodextrin inclusion compound medicine is: cyclodextrin has the tubular structure structure of " outer hydrophilic, interior hydrophobic ", can inclusion multi-medicament molecule, drug molecule by the tubular structure of inclusion or embedded rings dextrin formed ultra micron dispersion. Obtained cyclodextrin clathrate dispersion effect is good, it is easy to absorb, and release is slow, and side reaction is few, it is also possible to avoid the impact of the factors such as medicine light, oxygen, heat, strengthens medicine stability, makes pharmaceutical efficacy and storage life extend.
Described Nipagin complex esters plays antiseptical effect in this bait formulation.
Described phagostimulant includes tapioca starch, brown sugar and cracker meal, and tapioca starch is cheap, and nutritional labeling, brown sugar and the cookies such as the starch of ingesting required rich in red fire ant, protein are red fire ant and like having good palatability for the food of picked-up.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, this bait formulation adopts ethyl cellulose and cyclodextrin inclusion compound insecticidal constituent, it is possible to slow down insecticidal constituent degradation speed in the red fire ant body taken food and speed sent out by poison, eliminate the red fire ant not the taken food warning to this bait formulation, thus large area killing red ants.
2, the insecticidal constituent in this bait formulation is higher than red fire ant lethal dose, and killing effect is notable.
3. this bait formulation selects tapioca starch, brown sugar and cracker meal as phagostimulant, and it is with low cost, and good palatability, food ingestion are big, and bait formulation can be propagated fast and effectively in ant colony.
