Definition of Insecticide
Insecticides kill insects. They control pests and insects carrying disease. The main types are organochlorines, organophosphates, carbamates, pyrethroids, neonicotinoids, and regulators. Insecticides penetrate insects through contact or ingestion. Insecticides also kill insects by fumigation through respiration.
Mode of Action of Insecticides
Insecticides disrupt physiological processes in insects. The mode of action describes how the pesticide kills or inactivates a pest. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds, and mammals.
Examples of Insecticides
Insecticides kill insects. They control pests and insects carrying disease. Some insecticides target only larvae or pupae. Using biological insecticides can reduce toxicity to humans.
Insect populations can develop resistance. Their susceptible members die off. The resistant strains survive and multiply. They may form a new majority. Many insects acquired resistance to synthetic organic pesticides.
Insecticides are chemicals to kill fungus, bacteria, insects, diseases, snails, or weeds. Insecticides’ purpose is killing or dispelling insects. This is used in agriculture, forestry, storage, protection, and hygiene.
Deltamethrin is considered one of the most powerful synthetic pyrethroid insecticides. It seems slightly less toxic than bifenthrin. Its uses are less restricted indoors. Insecticides kill insects through contact, ingestion, or respiration. Fungal insecticides attack externally then penetrate internally.
