The cyclopoid copepod Macrocyclops albidus was evaluated as a biological control agent of Aedes aegypti and Culex quinquefasciatus larvae, culicides that frequently live in containers of domestic use in urban zones. The experiments were made under controlled laboratory conditions. Plastic containers with 5 L of dechlorinated water and 3 g of dry leaves were used.

The level of susceptibility and/or resistance of adult mosquitoes to lambda-cyhalothrin, clorpirifos and cypermethrin insecticides was determined in a strain of Aedes aegypti (L) collected in Playa municipality, Havana City. According to the results, the strain under study is not resistant to lambda-cyhalothrin and cypermethrin (FR < 5X), and it is as susceptible as the CAREC reference strain (FR=1) to chlorpyrifos.

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.
