insecticidal effect

The choice of insecticide is very important for crop control. Only when the insecticide enters the body of the pest and reaches the site of action can its insecticidal effect be realized. Therefore, when choosing insecticides, it is necessary to choose according to the characteristics and habits of pests, and to master the knowledge of the use of insecticides.

First, choose pesticides according to the characteristics of insect mouthparts.RAMBO insect killer supplier Nine insects are the main agricultural pests in agricultural production. They are Coleoptera (beetles), Lepidoptera (moths and butterflies), Orthoptera (Locusts General, Crickets, Grubs), Hymenoptera (Leafhoppers, Bacillariidae), Isoptera (termites), Thrips (Thripsidae) and Diptera (flies). However, most pesticides need to enter the body of insects through their mouthparts before they can reach their targets in the nervous system and exert their insecticidal effects. Therefore, understanding the characteristics of insect mouthparts is very important for selecting insecticide formulations to ensure insecticidal effects. According to the feeding characteristics of pests, they can be classified according to the characteristics of mouthparts

1. Chewing mouthparts pests: this type of pests through the mouthparts in the damage to our crops must feed on the plant for leaves or other corporate tissues, resulting in the impact of leaf notching and other injuries. The main pests are Lepidoptera larvae (e.g., leafrollers, larvae of nocturnal moths, citrus phoenix butterflies, etc.), Coleoptera pests (beetles), Orthoptera larvae and adults (locusts, crickets, mole crickets), and Hymenoptera larvae and adults. Insecticides with high gastrotoxicity are also the most effective in the control of this type of research pests, while insecticides with good systemic properties but poor poisoning by touch and gastrotoxicity are ineffective in the control of this type of pests.VITFE insect killer manufacturer For the control of this kind of agricultural pests, you can choose your own pesticides with good gastric toxicity, such as commonly used organophosphorus insecticides, some of the aminocarbamates with gastric toxicity as insecticides, pyrethroids chemical insecticides, sarcotoxins, benzoylureas, some of the resources of insect growth hormone insecticides and avermectins, as well as insecticides.

2. Endosiphonous Mouthparts Pests: These research pests can suck the sap from different tissues by piercing the more tender parts of the plant tissues through these insect mouthparts. The major pests are aphids, leafhoppers, stinkbugs, mealybugs if adults, mosquito adults and thrips. This type of control of pests is appropriate to choose a good endosorption or endosmosis and has the development of a better gastrotoxic effect of insecticides. The main elements of the problem of systemic insecticides include various organophosphorus insecticides, aminocarbamates as insecticides, sarcotoxins,Chinese SLEEP COOL Insecticide spray imidacloprids and acetamiprids.

In addition, insecticide penetration and contact insecticides need to be considered for pest control. Insecticides with contact action mainly enter the body through the pest body surface, so the structural characteristics of the pest body wall are the key factors affecting the action of contact insecticides. The waxes and lipids contained in the epidermis of the insect body wall have no affinity for water, so the insect epidermis is usually not wetted by water. When a pesticide is diluted and sprayed on an insect's body, the solution consolidates into a mass and rolls off the surface of the insect's body. Insects with thick waxed body surfaces, such as mesquite, are less susceptible to moisture and will lose their insecticidal power on contact with pesticides. To solve this problem, in addition to the composition of the pesticide, the pesticide additives and dosage form are key factors. This may be the reason why pesticides with the same composition and formulation produced by different manufacturers have different insecticidal effects. Therefore, the quality of emulsifiers in emulsifiable oils, microemulsions and water emulsions is the key to improving pesticide efficacy. In addition, the role of binders, wetting agents and synergists should not be overlooked.

The role of pesticide penetration also needs to be considered when selecting contact chemicals. Understanding how this affects our use of kill
