Embodiment 1

[0022] To configure 100 grams of RIFA poisonous bait, the following raw materials are required:

[0023] 0.02 grams of spinosad, 0.15 grams of preservatives, 99.83 grams of silkworm chrysalis powder;

[0024] The preparation method is:

[0025] A. Clean the silkworm chrysalis after silkworm cocoon spinning, drain them, dry them in a hot pot, sauté until fragrant, crush them while they are hot, and pass through a 10-mesh sieve to obtain 99.82 grams of silkworm chrysalis powder;

[0026] B, 99.83 grams of silkworm chrysalis powder and 0.15 grams of antiseptic are stirred and mixed;

[0027] C, with ethanol or acetone as solvent, spinosyn 0.02 gram is dissolved, is mixed with the insecticide solution of 0.2% concentration;

[0028] D. Spray the solution obtained in step C into the product obtained in step B, and stir while spraying. After mixing evenly, dry the whole material and pack separately to obtain poisonous baits with a particle size of 10 to 50 mesh.

Embodiment 2

[0030] To configure 100 grams of RIFA poisonous bait, the following raw materials are required:

[0031] 0.05 grams of fipronil, 0.15 grams of preservatives, 99.8 grams of silkworm chrysalis powder;

[0032] The preparation method is:

[0033] A. Clean the silkworm chrysalis after silkworm cocoon spinning, drain them, dry them in a hot pot, sauté until fragrant, crush them while they are hot, and pass through a 30-mesh sieve to obtain silkworm chrysalis powder;

[0034] B, 99.8 grams of silkworm chrysalis powder and 0.15 grams of antiseptic are stirred and mixed;

[0035] C, with ethanol or acetone as solvent, fipronil 0.05 gram is dissolved, and is mixed with the insecticide solution of 0.5% concentration;

[0036] D. Spray the solution obtained in step C into the product obtained in step B, and stir while spraying. After mixing evenly, dry the whole material and pack separately to obtain poisonous baits with a particle size of 10 to 50 mesh.

Embodiment 3

[0038] To configure 100 grams of RIFA poisonous bait, the following raw materials are required:

[0039] Indoxacarb 0.1g, preservative 1.0g, silkworm chrysalis powder 98.90g;

[0040] The preparation method is:

[0041] A. Clean the silkworm chrysalis after the silkworm cocoon has been spun, drained, dry in a hot pot, fry until fragrant, and pulverize while it is hot, and pass through a 50-mesh sieve to obtain silkworm chrysalis powder;

[0042] B, 98.9 grams of silkworm chrysalis powder and 1.0 grams of antiseptic are stirred and mixed;

[0043] C. Dissolve 0.1 g of indoxacarb with ethanol or acetone as a solvent to prepare a 0.5% concentration insecticide solution;

[0044] D. Spray the solution obtained in step C into the product obtained in step B, and stir while spraying. After mixing evenly, dry the whole material and pack separately to obtain poisonous baits with a particle size of 10 to 50 mesh.

Abstract

The invention discloses poison bait for killing solenopsis invicta, and a preparation method of the poison bait. The poison bait is prepared from the following raw materials by weight percent: 0.15-1.0% of a preservative, 0.005-0.8% of pesticide crude drug and 98.20-99.845% of an attractant, wherein the attractant is silkworm chrysalis meal. The preparation method comprises the steps of A. reeling off raw silk from cocoons, cleaning silkworm chrysalis by water, and then draining off; putting the silkworm chrysalis into a hot pot, drying, frying, grinding the silkworm chrysalis when the silkworm chrysalis is hot, and sieving to obtain the silkworm chrysalis meal; B. evenly mixing the silkworm chrysalis meal and the preservative; C. dissolving the pesticide crude drug by taking ethyl alcohol or acetone as a solvent, and preparing a 0.1-5% pesticide solution; D. spraying the solution obtained in the step C onto the product obtained in the step B, stirring while spraying, drying the whole material after evenly mixing, and respectively packaging. The poison bait is remarkable in solenopsis invicta killing effect, and has the effective killing rate of more than 98%; the silkworm chrysalis raw material is enough and convenient and easy to obtain, so that the poison bait is low in production cost; the poison bait belongs to a biological insecticide which is low in toxicity, efficient and less in residue.

Description

technical field [0001] The invention relates to a chemical insecticide, in particular to a poison bait for killing red fire ants and a preparation method thereof. Background technique [0002] The red fire ant (Solenopsis invicta) belongs to the order Hymenoptera (Formicidae) leafcutter ant subfamily (Myrmicinae) fire ant genus (Solenopsis), native to the Parana River (Parana) basin in South America, including Brazil , Paraguay, Argentina and other countries. In 2003, the first report of RIFA invasion was found in Taiwan, my country. In September 2004, after the first RIFA epidemic was discovered in Wuchuan City, Guangdong Province, RIFA invasions were also found in Guangxi, Hunan, Fujian, Hong Kong, Macau and other places. The invasion of RIFA often brings serious ecological disasters to the local area. It is the enemy of biodiversity protection and agricultural and forestry production. In addition to eating soil-dwelling animals in the soil, RIFA also directly eat plant r...
