Insecticides are a type of pesticide specifically designed to kill or control insect populations. They are widely used in agriculture, public health, and household settings to protect crops, prevent disease transmission, and eliminate pests.
Types of Insecticides:
Contact Insecticides - Kill insects upon direct contact.
Systemic Insecticides - Absorbed by plants and transferred to insects when they feed.
Stomach Poisons - Effective when ingested by insects.
Fumigants - Work through inhalation, often used in enclosed spaces.
Common Chemical Classes:
Organochlorides - Includes DDT, now banned in many countries due to environmental concerns.
Organophosphates - Affect insect nervous systems but can be toxic to humans.
Pyrethroids - Synthetic versions of natural pyrethrins, commonly used in household insecticides.
Neonicotinoids - Systemic insecticides that target sucking pests but have raised concerns about bee populations.
Insecticides play a crucial role in pest management, but their use must be carefully regulated to minimize environmental impact and resistance development in insect populations
