PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY - 2012 - Insecticide resistance in the major dengue vectors Aedes albopictus and Aedes aegypti. PLOS 10/04/17 Carboxylesterase gene amplifications associated with insecticide resistance in Aedes albopictus: Geographical distribution and evolutionary origin. Abstract Background Aedes albopictus is one of the most invasive human disease vectors.
Its control has been largely based on insecticides, such as the larvicide temephos. Temephos resistance has been associated with the up-regulation, through gene amplification, of two carboxylesterase (CCE) genes closely linked on the genome, capable of sequestering and metabolizing temephos oxon, the activated form of temephos. Principal findings Here, we investigated the occurrence, geographical distribution and origin of the CCE amplicon in Ae. albopictus populations from several geographical regions worldwide.
Significance The importance of passive transportation of disease vectors, including individuals carrying resistance mechanisms, is discussed in the light of efficient and sustainable vector control strategies. Author summary Control of mosquito borne diseases is being seriously challenged by the ongoing development of insecticide resistance. Introduction. PLOS 24/03/17 Rapid Surveillance for Vector Presence (RSVP): Development of a novel system for detecting Aedes aegypti and Aedes albopictus. Abstract Background The globally important Zika, dengue and chikungunya viruses are primarily transmitted by the invasive mosquitoes, Aedes aegypti and Aedes albopictus.
In Australia, there is an increasing risk that these species may invade highly urbanized regions and trigger outbreaks. We describe the development of a Rapid Surveillance for Vector Presence (RSVP) system to expedite presence- absence surveys for both species. Methodology/Principal findings We developed a methodology that uses molecular assays to efficiently screen pooled ovitrap (egg trap) samples for traces of target species ribosomal RNA. Conclusions/Significance RSVP can rapidly detect nucleic acids from low numbers of target species within large samples of endemic species aggregated from multiple ovitraps.
Author summary. PLOS 13/01/17 European Aedes albopictus and Culex pipiens are Competent Vectors for Japanese Encephalitis Virus. Abstract Background Japanese encephalitis virus (JEV) is the causative agent of Japanese encephalitis, the leading cause of viral encephalitis in Asia.
JEV transmission cycle involves mosquitoes and vertebrate hosts. The detection of JEV RNA in a pool of Culex pipiens caught in 2010 in Italy raised the concern of a putative emergence of the virus in Europe. We aimed to study the vector competence of European mosquito populations, such as Cx. pipiens and Aedes albopictus for JEV genotypes 3 and 5. Findings After oral feeding on an infectious blood meal, mosquitoes were dissected at various times post-virus exposure. Conclusions In this study, we demonstrated that European populations of Ae. albopictus and Cx. pipiens were efficient vectors for JEV transmission. J. Med.

Parasites & Vectors 2015 8:348 Standard operating procedures for standardized mass rearing of the dengue and chikungunya vectors Aedes aegypti and Aedes albopictus (Diptera: Culicidae) - II - Egg storage and hatching. Aedes albopictus and Ae. aegypti eggs hatch efficiently in a solution of bacterial broth while there is lower hatching in deionized water.
Fallis and Slow  observed such differences in Ae. punctor eggs, with no eggs hatching in deionized water alone and a variable rate between 30 and 90 % with the addition of bacterial broth. The fact that the bacterial broth hatching medium is efficient in inducing hatching of both Ae. albopictus and Ae. aegypti is interesting. Indeed, it is known that hatching can be induced by a different concentration of dissolved oxygen depending on the species, as observed by Judson al.  for Ae. sierrensis and Ae. aegypti.
Moreover, Schwan and Anderson  also observed variation in dissolved oxygen concentration required for optimal hatching of different strains of Ae. sierrensis. The decrease in quality could be due to a lethal loss of water; a strong correlation between changes in weight and hatch rate has been already demonstrated [28, 34].

Controlling Aedes albopictus, commonly known as the Asian tiger mosquito, presents particular challenges.
An interesting pilot study being conducted in Italy has seen researchers adapt a method which was the subject of experimentation in South America to control Aedes aegypti. The ‘auto-dissemination’ method uses adult mosquitoes to transfer insecticides (juvenile hormone analogues or JHA) to larval habitats (you can read more about the work conducted in Peru in the Proceedings of the National Academy of Sciences of the United States of America . EDENext caught up with Alessandra della Torre, of the University of Rome ‘La Sapienza’ and EDENext’s mosquito-borne disease group, to find out more.
EDENext: Why is the control of Aedes albopictus difficult and how does this new method work? The idea was that if the natural wild adult females contaminate their legs with these hormones, when they lay eggs they contaminate the breeding sites and in this way larvae cannot grow. PLOS 29/03/13 Effects of Biogents Sentinel Trap Field Placement on Capture Rates of Adult Asian Tiger Mosquitoes, Aedes albopict. The Biogents® Sentinel (BGS) trap is the standard tool to monitor adult Aedes (Stegomyia) albopictus (Skuse) (Diptera: Culicidae), the Asian tiger mosquito.
BGS traps are commonly placed in residential properties during surveillance operations, but locations within properties may have significant differences in ambient light, temperature, and humidity (e.g. between a sunlit lawn and shady underbrush). We examined the effect of BGS trap placement on Ae. albopictus capture rates in three residential properties in Monmouth County, New Jersey, USA. In each property we visually selected locations as shade, partial shade, and sun. Traps in “partial shade” locations were under vegetation and were exposed to filtered sunlight during some parts of the day while “shaded” locations were never exposed to direct sunlight.
Locations defined as “sun” were exposed to direct sunlight for large parts of the day. Figures Editor: Rick Edward Paul, Institut Pasteur, France.

Aedes albopictus. Description Name and systematics In 1894, a British-Australian entomologist, Frederick A.
Askew Skuse, was the first to describe scientifically the Asian tiger mosquito, which he named Culex albopictus (lat. Culex “gnat, midge” and albopictus “white embroided”). Later, the species was assigned to the genus Aedes (gr. άηδής, "unpleasant") and referred to as Aedes albopictus. Like the yellow fever mosquito, it belongs to the subgenus Stegomyia (Gr. στέγος, "covered, roofed", referring to the scales that completely cover the dorsal surface in this Subgenus, and μυία, "fly") within the Aedes genus. In 2004, scientists explored higher-level relationships and proposed a new classification within the Aedes genus and Stegomyia was elevated to the Genus level, making Aedes albopictus now Stegomyia albopicta.
This is, however, a controversial matter, and the use of Stegomyia albopicta versus Aedes albopictus is continually debated. Characteristics Vector-Borne and Zoonotic Diseases. 8: 25-34 2008 Geographic distribution and developmental sites of Aedes albopictus (Diptera:
