Description
Technical Field
The invention relates to the technical field of pest control, in particular to a compound solenopsis invicta killing agent without traditional pesticide.
Background
The red fire ants belong to hymenoptera, formicoidae, phylloideae and genus of fire ant, are native to south america, are "invincible" ants by latin, are world quarantine pests and are difficult to control. The red imported fire ants invade China in 2004, and currently spread to 12 provinces, 435 counties and cities in China, and particularly 191 county-level administrative districts where newly added red fire ants occur in nearly five years are doubled compared with 2016.
The red imported fire ant has obvious aggressive and repeated stinging capability to human and animals. It affects the health and quality of life of people in the invaded area, has serious effects on agriculture, livestock, wildlife and natural ecosystems, and it also damages the electronics of public facilities, resulting in financial loss in communication, medical treatment and pest control. The red imported fire ants cause serious ecological disasters in the invaded zone and are large enemies of biodiversity protection and agricultural production. The solenopsis invicta is fed with seeds, roots, fruits and the like of various crops, and the seedlings are damaged, so that the yield is reduced. It damages the irrigation system, reduces work efficiency, attacks livestock, and causes agricultural losses. Solenopsis invicta also has serious effects on wild animals and plants. It can attack eggs of turtles, lizards, birds, etc., and has a negative effect on the density of small mammals and invertebrate communities.
Because of the great harm of the red fire ants, the invasion of the red fire ants arouses the attention of relevant departments, and physical control methods such as burning, nest digging and soaking, mechanical destruction and ant nest boiling water treatment, and chemical control methods such as ant nest pesticide filling, bait trapping and killing and the like are adopted.
The existing prevention and control methods for the solenopsis invicta adopt the traditional agriculture as a main component generally, so that the environment is damaged; the physical prevention and treatment method has the problems of poor effect and the like.
Disclosure of Invention
The invention aims to provide a compound type solenopsis invicta killing agent without traditional pesticides to solve the problems.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a composite solenopsis invicta killing agent without traditional pesticides comprises the following raw materials in parts by weight: 1-30 parts of baeckea frutescens, 1-15 parts of n-butanol, 1-15 parts of coumarin, 1-15 parts of ethanol, 1-50 parts of silicon dioxide and an extraction solvent for extracting the baeckea frutescens.
As a preferred technical scheme: the extraction solvent is petroleum ether. Of course, as will be appreciated by those skilled in the art, other non-polar solvents may be used for the extraction, such as n-hexane and the like, with petroleum ether being preferred because it is simpler to work with.
As a preferred technical scheme: also comprises 1-15 parts of ethyl acetate.
In the components of the invention, the Baeckea frutescens L is a myrtaceae plant, the Baeckea plant is a traditional Chinese medicine, the Baeckea plant is generally used as a branch and leaf part of a traditional Chinese medicine and generally used as a stasis-removing medicine and an analgesic, and a large number of experiments prove that the branch and leaf part of the Baeckea plant is crushed and then extracted by adopting a proper amount of petroleum ether, and the extract can be used for killing red imported fire ants by adding a proper amount of n-butyl alcohol to increase the activity; adding coumarin and silicon dioxide, wherein the coumarin can inhibit the generation of blood coagulation factors of the solenopsis invicta to cause the solenopsis invicta to bleed and die in a large amount, the crystal of the silicon dioxide can pierce the skin of the solenopsis invicta to cause the blood vessel of the solenopsis invicta to rupture and bleed, and the silicon dioxide can block the valve of the solenopsis invicta after entering the body of the solenopsis invicta to cause the solenopsis invicta to suffocate and die; furthermore, the addition of ethyl acetate helps the silica to absorb the water in the red imported fire ant body, so that the red imported fire ant is dried and dead.
As a preferred technical scheme: the composite material comprises the following raw materials in parts by weight:
10-30 parts of baeckea frutescens, 3-10 parts of n-butanol, 3-10 parts of coumarin, 2-8 parts of ethyl acetate, 2-8 parts of ethanol and 10-35 parts of silicon dioxide.
By adopting the proportion, better killing effect can be obtained.
As a further preferable technical scheme: the composite material comprises the following raw materials in parts by weight:
20 parts of baeckea frutescens, 5 parts of n-butyl alcohol, 5 parts of coumarin, 5 parts of ethyl acetate, 5 parts of ethanol and 35 parts of silicon dioxide.
By adopting the proportion, the best killing effect can be obtained.
The preparation method of the compound type solenopsis invicta killing agent without traditional pesticide comprises the following steps: weighing the components, crushing the baeckea frutescens, adding petroleum ether for at least one extraction, combining the petroleum ether layers, adding n-butyl alcohol, then pouring into ethanol, finally adding ethyl acetate and silicon dioxide, and mixing to obtain the baeckea frutescens.
As a preferred technical scheme: pulverizing the Baeckea frutescens to 30-100 meshes.
Compared with the prior art, the invention has the advantages that: the solenopsis invicta killing agent provided by the invention does not contain traditional pesticides, is basically harmless to human and animals except solenopsis invicta, has very good specificity and specificity, is excellent in killing effect, can achieve the killing effect on the solenopsis invicta of more than 99.5%, and is low in raw material cost, easy to obtain and convenient to operate.
Detailed Description

Effect testing
The effect test is to test the killing effect of the solenopsis invicta by using the above examples 1-5 and comparative examples 1-5 as test samples, respectively.
Test samples: use of solenopsis invicta pheromone (commercially available, although sugars and starches may be used instead of pheromone) + the killing agent of the present application;
the test was carried out in divided test numbers 1, 2, 3,4,5, 6, 7,8,9,10, wherein numbers 1-5 used "pheromone + insecticide of examples 1-5", numbers 6-10 used the same pheromone as numbers 1-5 + insecticide of comparative examples 1-5, 10 ant nests per test area, 10 flags were inserted in the test area before application, 10 areas were marked, 10 test specimens (5 g/one) were placed on or around the ant nest with red fire ant traps per area, once per week, 4 times in total, and after placing the traps, it was observed that 10 red fire ants in the area all fell out within 10 minutes to carry the bait.
After being placed for 1 week, dead workers around No. 1,3,4 and 5 and a large number of dead winged breeding ants appear; no. 6, 7,8,9 and 10 workers can move around, and no winged breeding ants are found;
and (3) digging the ant nest to check whether the worker ants of the red fire ants are active or not in the 5 th week, judging the ant nest to be a healthy ant nest if a large number of worker ants are active, and considering the ant nest to be dead if no worker ant activity occurs and no new ant nest occurs in the surrounding 10m by taking the ant nest as the center:
as a result: the 10 No. 1 ant nests have multiple ant nest collapses, no new ant nest appears, and the mortality rate is 100%; the mortality rate of the No. 2 nest is 81%, the mortality rate of the No. 3 nest is 93%, the mortality rate of the No. 4 nest is 92%, the mortality rate of the No. 5 nest is 90%, the mortality rate of the No. 6 nest is 39%, the mortality rate of the No. 7 nest is 77%, the mortality rate of the No. 8 nest is 76%, the mortality rate of the No. 9 nest is 83%, and the mortality rate of the No. 10 nest is 71%.
