Introducción. El desarrollo de la resistencia a insecticidas de Aedes aegypti representa una gran amenaza para la salud pública. La vigilancia y el monitoreo de la eficacia biológica a los insecticidas y la sensibilidad de las poblaciones de Aedes aegypti es de fundamental importancia para prolongar l...
Introducción. El dengue es un problema de salud pública para el departamento de La Guajira. El control se ha enfocado en el vector con el uso de insecticidas, entre ellos los organofosforados. Objetivo. Evaluar el estado de la sensibilidad a insecticidas organofosforados de quince poblaciones de Aedes ...
Abstract Development of insecticides resistance mainly hinge with managements techniques for the control of Jassid, Amrasca biguttutla biguttutla. Five insecticides were applied against field collected and laboratory rared jassid populations during the years of 2017 to 2019 to profile their resistance le...
Abstract Application of different fertilizers to check the efficiency of expression of Bt (Bacillus thuringiensis) gene in one of the leading commercialized crops (cotton) against Lepidopteran species is of great concern. The expression of Cry protein level can be controlled by the improvement of nutrien...

Introdução: cerca de quatro bilhões de pessoas residem em áreas com risco de dengue, uma arbovirose transmitida pelo mosquito Aedes (Stegomyia) aegypti (Linnaeus, 1762) (Insecta, Diptera, Culicidae). Na tentativa de combater esse vetor e reduzir a disseminação da dengue, o meio de controle vetorial...
Background
Triatoma infestans is the main vector of Chagas disease in the Southern Cone. The resistance to pyrethroid insecticides developed by populations of this species impairs the effectiveness of vector control campaigns in wide regions of Argentina. The study of the global transcriptomic response t...
We assessed whether fluralaner administered to outbred healthy dogs reduced or supressed site infestation and abundance of pyrethroid-resistant populations of Triatoma infestans Klug (Heteroptera: Reduviidae). We conducted a placebo-controlled before-and-after efficacy trial in 28 infested sites in Caste...
O mosquito Aedes aegypti é vetor competente para a transmissão dos vírus dengue, chikungunya, Zika e febre amarela. O controle químico do vetor é amplamente utilizado, mas vem sendo ameaçado pela disseminação da resistência a inseticidas (RI), caracterizando-se pela seleção de alterações no ...
Abstract INTRODUCTION: Since 2013, major Cimex lectularius infestations have been detected in public shelters in Belo Horizonte (Brazil). Due to this, insecticide resistance has been investigated as one of the possible causes for the failure to control bedbugs. METHODS: Cimicids were subjected to bio...
ABSTRACT OBJECTIVE: To evaluate locomotor activity in four field populations of Ae. aegypti with different insecticide resistance profiles from the state of São Paulo for two years. METHODS: This study comprised the susceptible Rockefeller strain and four populations from São Paulo, Brazil: two consi...
