A preparation method of a solid pesticide for controlling wood bees comprises the following steps: heating and dissolving the curing agent in an organic solvent, adding the active ingredients, fully dissolving, uniformly mixing, pouring into a mould, cooling and shaping to obtain the finished product of the product.
The invention also provides a use method of the solid pesticide for controlling wood bees, which comprises the following steps:
taking about 2g of finished product, and plugging at the wood honeycomb cave entrance, wherein the solid medicament is softer before the organic solvent is completely volatilized, is easy to shape, and can well plug the wood honeycomb cave entrance. And killing all wood bees in the nest within 3-7 days.
In the invention, the harmful pests in the wood structure building are mainly different types of wood bees, such as Huang Xiongmu bees, trichogramma, longhorn bees and the like, and also can be longhorn beetles and larvae thereof. When the solid insecticide is used, the solid insecticide can be directly plugged into nest inlets of pests, and the pests in the whole nest can be killed through fumigation.
According to the characteristics of nest holes left when wood is damaged by wood bees, the medicament is manufactured into a medicament strip with the diameter of about 8-10mm, and the medicament is directly put into the entrance of the wood bees when in use, or directly seals the entrance of the nest, can be further firmly adhered by adhesive tapes, and can kill the whole nest wood bees through fumigation.
Biological Activity test
According to the method, the solid insecticide agent 1 is prepared, 100g of the solid insecticide agent 1 is prepared, about 3g of the solid insecticide agent 1 is taken in the evening of 29 days of 4 months of 2022, the solid insecticide agent 1 is directly plugged into the entrance of a wooden honeycomb hole, and after 5 days, the wooden honeycomb is planed to observe the survival state of the wooden honeycomb. 6 wood beehives are treated in total. Table 1 is statistics of survival status of wood bees after treatment.
TABLE 1 insecticidal Activity of solid insecticide blocking Apis cerana nest (5 days)
From table 1 it can be seen that the solid insecticide is fast and effective in killing wood wasp adults in the hives, the adult mortality rate of 6 hives is 100%, and only the outermost one of the larvae is killed. Analyzing the reason, the wood bee larvae have intervals formed by wood chips, and as shown in figure 1, the gas medicament is difficult to quickly permeate, so that the medicament has low activity of killing the larvae in a short time; moreover, the nest inlet is blocked, the adult tries to fly out of the nest inlet and is necessarily contacted with the solid insecticide, and the contact killing and stomach poisoning effects of the insecticide can also accelerate death of the adult. The solid insecticide is used for preventing and controlling the timing of taking the medicine, the wooden bees just end hibernation and do not lay eggs in the beginning of 3 months in winter every year, the habit of the wooden bees for homing in the evening can be utilized, and the solid insecticide is used for killing the adult wooden bees in a concentrated time.
