Journal ArticleDOI
Detection of a New Pyrethroid Resistance Mutation (V410L) in the Sodium Channel of Aedes Aegypti: A Potential Challenge for Mosquito Control
Khalid Haddi,Hudson V. V. Tomé,Yuzhe Du,Wilson R. Valbon,Yoshiko Nomura,Gustavo Ferreira Martins,Ke Dong,Eugênio E. Oliveira +7 more
TL;DR: The V410L mutation drastically reduced the sensitivity of mosquito sodium channels expressed in Xenopus oocytes to both type I and type II pyrethroids and presents a serious challenge for the control of A. aegypti in Brazil.
Journal ArticleDOI
Larvicidal effect of essential oils from Brazilian cultivars of guava on Aedes aegypti L.
Luiza Alves Mendes,Gustavo Ferreira Martins,Wilson R. Valbon,Tércio da Silva de Souza,Luciano Menini,Adésio Ferreira,Marcia Flores da Silva Ferreira +6 more
TL;DR: The chromatographic profile of the essential oils evidenced mainly sesquiterpenes; hence, this group of compounds may be responsible for the larvicidal effect of A. aegypti, constituting a larvicide alternative.
Journal ArticleDOI
Diversity and convergence of mechanisms involved in pyrethroid resistance in the stored grain weevils, Sitophilus spp.
Khalid Haddi,Wilson R. Valbon,Luis O. Viteri Jumbo,Luiz Orlando de Oliveira,Raul Narciso C. Guedes,Raul Narciso C. Guedes,Eugênio E. Oliveira +6 more
TL;DR: The results suggest that the selection of pyrethroid-resistant individuals in these weevil species may result from multiple and differential mechanisms because the L1014F mutation was only detected in Latin American rice weevils (e.g., Brazil, Argentina and Uruguay), not in Australian and Turkish riceweevils or Brazilian maize weevILS.
Journal ArticleDOI
Chemical Composition of Essential Oil from Eucalyptus citriodora Leaves and Insecticidal Activity Against Myzus persicae and Frankliniella schultzei
Adilson Vidal Costa,Patrícia Fontes Pinheiro,Vagner Tebaldi de Queiroz,Vando Miossi Rondelli,André Kulitz Marins,Wilson R. Valbon,Dirceu Pratissoli +6 more
TL;DR: Essential oils, volatile compounds obtained from plants, provide an alternative approach for controlling agricultural pests due to problems with conventional chemical products, such as insect resistance, environmental issues and human health concerns.
Journal ArticleDOI

TL;DR: In this paper, the principal components of pyrethrum, pyrethrins, and a minor component, (E)-β-farnesene (EBF), each activate a specific type of olfactory receptor neurons in Aedes aegypti mosquitoes.
