[Efficacy of the intradomiciliary treatments with cypermethrin, lambda-cyhalothrin and chlorpyrifos insecticides in an Aedes aegypti strain].

Field bioassays were conducted to determine the efficacy of the intradomiciliary treatments of thermal fogging and ULV with formulations of cypermethrin, lambda-cyhalothrin and chlorpyrifos by using an Aedes aegypti strain from Playa municipality, Havana City, Cuba. The results show in all cases that the thermal treatments are more efficient than those of ULV. As regards chlorpyrifos 48 EC insecticide it caused in both types of treatment 100% of mortality without adding DDVP (Dichlorvos 50%), whereas for cypermethrin 25 EC it was obtained 100% of mortality in thermal treatments with DDVP or without it.
