Description
Technical Field
The invention relates to the technical field of pest control, in particular to a population regulator for controlling soil termites, a preparation method and application thereof.
Background
Soil termites are a class of termites that nest in the subsurface, and feed on trees, leaves, fungi, and the like. Subterranean termites, such as black-wing subterranean termites and yellow-wing large termites, are the most common two types of subterranean termites in China, and take living trees, stumps, branches of dried plants, shrubs, herbaceous herbivores, herbivores and the like as food. In natural environment, they build large nests underground, and by going out to forage, they cause harm to new forestation sites, landscaping and hydraulic engineering.
In order to prevent and treat the harm of soil termites such as black wing termites, yellow wing termites and the like, chemical barriers are established in a mode of mixing chemical agents in soil or spraying chemical agents on the surface of the soil in China for a long time. For example, chinese patent publication No. CN107410352a discloses a termite control agent comprising: 2 to 5 weight percent of bifenthrin, 2 to 5 weight percent of chlorpyrifos and 1 to 2 weight percent of hexaflumuron. The Chinese patent document with publication number CN1234274C discloses a termite control agent which comprises, by weight, 0.28-0.6 of permethrin, 0.001-0.01 of deltamethrin, 1.3-2.6 of synergistic agent and a proper amount of solvent. However, the chemical agent has short duration and pollutes the environment, so the termite control industry in China is forced to need a long duration and environment-friendly technology and method for controlling the harm of termites to forests, greening and hydraulic engineering.
Under the field condition, when the external condition is proper, winged adults in the soil-dwelling termite nest fly out of the nest, the male and female pairing is carried out, a new place 'Anjia' is found, and a new population is established again after the next generation is generated after the settlement. Then, the workers take the tasks of establishing a nest, taking food outside and forming a fungus garden, and the breeding ants are responsible for breeding offspring. Therefore, if the fertility of the breeding termites can be regulated, the harm of the soil termites can be effectively controlled.
Arachidonic acid plays an important role as a phospholipid-bound structural lipid in animal blood, liver, muscle and other organ systems, and is a direct precursor of many circulating eicosanoic acid derivatives, such as prostaglandin E2 (PGE 2), prostacyclin (PGI 2), thromboxane A2 (TXA 2) and leukotrienes and C4 (LTC 4). These bioactive substances have important regulatory effects on lipoprotein metabolism, haemorheology, vascular elasticity, leukocyte function, platelet activation, etc.
