Specification Parameters

Mode of Action

S-Bioallethrin acts on the nervous system of insects by targeting voltage-gated sodium channels. It prolongs the opening of these channels, causing repetitive nerve firing, leading to rapid paralysis and death of the insect. Its high potency and fast knockdown effect make it particularly effective against mosquitoes, flies, cockroaches, and other household and agricultural pests.

Applications

• Public Health: Widely used in mosquito coils, aerosols, and space sprays for controlling mosquito vectors of diseases like malaria, dengue, and Zika.

• Agriculture: Controls various insect pests on vegetables, fruits, cotton, and other crops.

• Veterinary: Used in formulations for controlling ectoparasites like ticks, fleas, and lice on pets and livestock.

• Household: Ingredient in insecticide sprays, mats, and repellents for domestic pest control.

• Formulations: Used as a raw material in emulsifiable concentrates (EC), aerosols, coils, mosquito mats, and liquid vaporizers.

Toxicological Profile

• Oral LD₅₀ (rat): >500 mg/kg (moderate toxicity)

• Dermal LD₅₀ (rabbit): >2000 mg/kg (low toxicity)

• Skin Irritation: Mild irritant

• Eye Irritation: Mild irritant

• Sensitization: Possible skin sensitizer

• Environmental Impact: Toxic to aquatic organisms and bees; handle with care to minimize environmental exposure.
