[The insecticidal activity of thermal aerosols of permethrin]

The aerosols derived from the designed 2% permethrine-containing pyrotechnical formulations (tablets and briquets) were tested for their effects in laboratory and field conditions. When tested in the chamber, its LC50 and LC99 were 0.056 and 0.43 mg/m2 (as calculated for the active ingredient), respectively, for Ae. aegypti mosquitos exposed to 15 min in the polycarprolactam plastic trap and 2.99 and 5.66 mg/m2 (for the active ingredient) for M. domestica flies exposed to an hour. LC99 for C. pipiens ranged 2 to 5 mg/m2 in the field conditions when treating the basements with varying airtightness. The effective dosage ensuring a 100% death of M. domestica in the animal-breeding premises of various types is 10 mg/m2 on an hour exposure.
