INTRODUCTION in dengue outbreaks or epidemics, the chemical pesticides play a fundamental role to control disease-borne adult mosquitoes and to support the Vector Control program in Cuba. OBJECTIVES to find out the effectiveness and the efficiency of insecticidal formulations in use for the control of Aedes aegypti mosquito in three strains from the City(More)
INTRODUCTION despite the Cuban government's efforts to exert control over the dengue vector Aedes aegypti, this mosquito is still present in several municipalities of the City of Havana and those of other provinces. OBJECTIVE to find out some aspects related to the existence of Ae. aegypti in 2 Cuban regions. METHODS a complete sampling was performed in(More)
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(More)
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(More)
The level of susceptibility and/or resistance in larvae and adults of an Aedes aegypti strain (L.) collected in Santiago de Cuba to lambda-cyhalothrin, chlorpyrifos, and cypermethrin. was determined. The results showed that in the larval stage the strain under study was susceptible to lambda-cyhalothrin (RR90 = 2.1) chlorpyirifos (RR90 = 1.3), and(More)
INTRODUCTION in the fight for environmental protection, finding out alternative ways to control vectors that are important from the medical viewpoint is a must. Those plants having potent active principles and high chemical stability to act as pesticides can contribute to this end. OBJECTIVE to evaluate the possible inhibitory effect of(More)
