Technical Field

The invention belongs to the technical field of pesticides, and particularly relates to an environment-friendly bait for killing Taiwan lactotermite.

Background

The main methods for termite control are: physical control and chemical control. Physical control is mainly to establish a barrier (such as sand, stainless steel mesh, etc.) for preventing termites from entering by using a physical method. The physical prevention and treatment in China are still in a groping and exploring stage, and the practical application is few. In China, chemical control is still the main control for termite control, and commonly used control medicines include imidacloprid, bifenthrin, chlorpyrifos and the like. Imidacloprid is a nicotine high-efficiency pesticide, has multiple effects of contact poisoning, stomach toxicity, systemic absorption and the like, has a good control effect on termites, has extremely high toxicity on highly toxic pesticides of silkworms and shrimps, and has potential toxicity (especially genetic toxicity) on bees. In 8 months 2017, the european union proposed that imidacloprid be banned from use in open air environments. Bifenthrin is a high-efficiency synthetic pyrethrin insecticide and acaricide, has a special chemical structure, has both high-efficiency poisoning effect and unique repelling effect, has a longer lasting period than chlorpyrifos, so that the bifenthrin has longer effective control time and better control effect when being used for preventing termites in a newly-built house, can exist in the environment for a long time, has potential biological enrichment effect and biological amplification risk at the same time, can cause unacceptable risk to the aquatic environment, and European Committee decides to gradually eliminate bifenthrin as insecticide and acaricide and is planned to be prohibited to be used in a greenhouse. Chlorpyrifos is an organophosphorus insecticide, has the effects of contact poisoning, stomach poisoning and fumigation, and has strong stomach poisoning and contact poisoning effects on odontotermes formosanus and formosanus. However, high doses of chlorpyrifos can lead to a reduction in cognitive ability of the animal, and prolonged exposure to low doses can also affect higher cognitive functions in the central nervous system. In recent years, due to the continuous discovery of the biotoxicity of chlorpyrifos and the environmental safety issues that it creates, the united states and european union countries have banned chlorpyrifos to some extent.

Since 2009, termite monitoring and control systems have been rapidly developed domestically. The termite monitoring and controlling system is characterized in that a monitoring and controlling device is buried in soil around a house building, when termites invade into the monitoring and controlling device to eat, the termites are treated by bait or powder, and the purpose of killing the termites in a whole nest is achieved through the virulence transmission function. The method can monitor the termites in the building construction area for a long time, prevent the termites from invading due to the failure of the chemical barrier, use a very small amount of medicine when discovering the termites invade, release a very small amount of toxic chemicals in the environment, and avoid the possible environmental pollution risk caused by the release of a large amount of toxic chemicals in the soil barrier treatment. At present, the termite control powder inquired on a pesticide information network comprises the following components: the pesticide composition comprises 0.5% of fipronil powder (fipronil is medium in toxicity, wide in insecticidal spectrum, has contact toxicity, stomach toxicity and moderate systemic action, has great toxicity to bees and aquatic organisms and is not friendly to the environment, and the requirement of the ministry of agriculture is that from 7.1.2009, pesticide preparations containing fipronil components are stopped selling and used in other aspects in China except for sanitary and part of upland field seed coating agents), 98% of disodium octaborate tetrahydrate (used for pressure soaking of wood), 98.8% of zinc borate (used for adding in board processing), cypermethrin (medium in toxicity, has stimulation to skin mucosa and is not suitable for being used as a soil pesticide).

Termite control medicines belong to sanitary pesticides and are closely related to daily life of people. The traditional control method has large dosage and high application concentration; conventional drugs present potential safety hazards to ecology, humans, livestock and non-target organisms. And the ecological environment of China is generally fragile and ecological safety is severe at the present stage, and the termite control bait is efficient and environment-friendly, can better relieve the problems that chemical pesticides destroy ecology and the like, and conforms to the trend of the progress of the times.

Disclosure of Invention

The invention aims to provide an environment-friendly bait for killing the Taiwan lactotermite so as to solve the problems that the existing termite pesticide pollutes the environment and destroys the ecology.

In order to achieve the technical purpose, the invention specifically adopts the following technical scheme:

the environment-friendly bait for killing the Opiophoides formosanus comprises the following components: the flonicamid-borne pesticide comprises flonicamid and a carrier, wherein the mass ratio of the flonicamid to the carrier is more than or equal to 5mg:14 g.

Preferably, the minimum content of flonicamid is 357 mg/kg.

The bait agent also comprises a solvent, and the solvent is selected from 75% alcohol.

The carrier is selected from masson pine blocks.

The invention also provides a preparation method of the bait for killing the Opiophoides formosanus, which comprises the following steps:

1) taking a masson pine block, placing the masson pine block in a constant-temperature drying oven, keeping the temperature for 24 hours at the temperature of 60 +/-1 ℃, and weighing the masson pine block after the temperature is restored to room temperature;

2) weighing flonicamid in a beaker, adding 75% alcohol for dissolving to form 2500mg/kg of liquid medicine;

3) immersing the masson pine blocks in the liquid medicine, and sealing the beaker;

4) taking out the wood block after 24 hours, weighing, and calculating the weight of the liquid medicine absorbed by the wood block and the content of the medicament;

5) standing in indoor environment for 3 days, and calculating the content of the dried wood block medicament to be 357mg/kg when the alcohol is completely volatilized;

6) packaging to obtain the environment-friendly bait for killing the Taiwan lactotermite.

When the bait is used, bait is firstly put in to lure a large number of termites, and then the bait is put in, according to the fact that the termites are social insects and have obvious grade differentiation and life habits of sympodial behaviors, after workers eat the bait, the workers feed soldiers and queen termites and then transmit the toxicity of the medicine to the whole termite nest group. Under the use concentration of the pesticide, the flonicamid is not less than 357mg/kg, has no evasion to termites, has slow drug toxicity, and can achieve the purpose of killing the termites in a whole nest with little drug dosage.

The invention has the beneficial effects that:

the environment-friendly bait for killing the Taiwan lactotermites, disclosed by the invention, has the main component content of flonicamid, has a poisoning effect on the termites and has no evasion to the termites. Flonicamid is a novel low-toxicity pyridine amide insect growth regulator pesticide, has the effects of contact poisoning and stomach poisoning, also has good nerve toxicant and quick antifeedant effect, and is widely used for preventing and treating piercing-sucking mouthpart pests. The problem of bee venom causes that neonicotinoid insecticides are forbidden or limited to be used in a plurality of countries and regions in the world, and flonicamid has low toxicity to bees, good safety to people, livestock, ecological environment and the like, and good development prospect. Termite control medicines belong to sanitary pesticides and are closely related to daily life of people. The traditional control method has large dosage and high application concentration; conventional drugs present a potential safety hazard to ecology, humans, animals and non-target organisms. The research and development of the green environment-friendly drug for preventing and controlling the termites are in line with the trend of the era. The environment-friendly bait for killing the Opiophoides formosanus can achieve the aim of killing the whole nest of termites with small dosage.
