Objective: To evaluate the presence of Elizabethkingia anophelis infection in Aedes albopictus wild populations of Southern Mexico.
Materials And Methods: Eight sites were selected to collect Aedes albopictus in the Soconusco region, Chiapas, females were analyzed to amplify the Gyrase B gene by PCR, the minimum infection rate of E. anopheliswas calculated and its species was determined by sequencing and phylogeny.
Results: The presence of E. anophelis was only observed in Huehuetán with a minimum infection rate of 37.8%.
Conclusion: A local strain of E. anophelis was detected for the first time in Ae. albopictus from Chiapas and this bacterium could be considered a candidate for study as a probable control agent or as a vehicle for transgenesis.

Background: The risk of mosquito-borne disease transmission is increasing in temperate climates with the colonization and proliferation of the Asian tiger mosquito vector Aedes albopictus and the rapid mass transport of passengers returning from tropical regions where viruses are endemic. The prevention of major Aedes-borne viruses heavily relies on the use of insecticides for vector control, mainly pyrethroids. In Europe, only deltamethrin is authorized.

Aedes aegypti and Aedes albopictus are the main vectors of arboviruses such as dengue, Zika virus, and chikungunya. Ae. aegypti is a widely spread mosquito in tropical and subtropical regions, whereas Ae.

Chikungunya virus (CHIKV) is mainly transmitted by the invasive mosquito () in tropical and subtropical regions worldwide. However, genetic adaptations of the virus to the peri domestic mosquito vector () has resulted in enhanced vector competence and associated epidemics and may contribute to further geographic expansion of CHIKV. However, evidence-based data on the relative role of in CHIKV transmission dynamics are scarce, especially in regions where is the main vector, such as in Brazil.

Introduction: Mosquitoes represent a way of spreading infectious diseases, as vectors of pathogens. Many types of ultrasonic devices have recently been promoted as effective and suitable alternatives to the use of biocides known as toxic to humans and environment.
Materials And Methods: Four ultrasonic mosquito repellers have been analysed and tested on females of two species, Culex pipiens and Aedes albopictus, in laboratory conditions.
