Temporal distribution of, and effect of anthropic modifications on, phlebotomine populations in the Chaco Bioregion, Argentina
Abstract
The Phlebotominae (Diptera: Psychodidae) are insects of medical and veterinary importance, because some species are able to transmit pathogens such as Leishmania spp. In the last 20 years, numerous leishmaniasis outbreaks have been reported in the Chaco Bioregion (Argentina), with an increasing trend of cases associated with periurban transmission. The Chaco Bioregion has two sub‐regions according to their climatic and ecological characteristics: the Dry Chaco and the Humid Chaco. In the present study, sandfly captures were performed in both sub‐regions, at sites with different levels of anthropic modificati...

Bionomics of livestock ‐associated Culicoides (biting midge) bluetongue virus vectors under laboratory conditions
This study reports on the bionomics of livestock‐associated vector Culicoides species under laboratory conditions. Insects were collected from the field from spring to autumn 2014 on a cattle farm in Spain. Eggs obtained from gravid females were maintained for larval rearing and pupal development. Culicoides imicola Kieffer took the longest time to oviposit; the highest number of eggs was laid by Culicoides circumscriptus Kieffer (148.7 ± 73.8 eggs). Field‐collected gravid C. imicola and Obsoletus complex females showed the longest lifespans. The longest lifecycle, generally more than 40 days, was recorded for C...

The effects of acaricide treatment of sheep on red grouse Lagopus lagopus scotica tick burdens and productivity in a multi ‐host system
This study examines the effects of sheep management on grouse tick burdens and productivity using sites with a range of wild host densities. Sites at which applications of acaricide were more frequent had lower tick burdens; this relationship was similar on sites with a range of deer densities. However, no direct link was detected between acaricide treatment interval and grouse productivity. Sites with higher deer densities had higher grouse tick burdens and lower productivity [mean ± standard error (SE) young : adult ratio: 1.2 ± 0.2] compared with sites with lower deer densities (mean ± SE young : adul...

Vectorial status of the Asian tiger mosquito Aedes albopictus of La R éunion Island for Zika virus
Abstract
La Réunion Island has been the scene of unusually large epidemics of dengue (DENV) and chikungunya (CHIKV) viruses with Aedes albopictus Diptera, Culicidae (Skuse, 1894) as the sole vector. The emergence of Zika virus (ZIKV) in 2007 and the spread of the epidemic strain of the Asian genotype through the Pacific region and the Americas, mainly via the vector Aedes aegypti (Linnaeus, 1762), has raised concern about its possible introduction to, and transmission in, Ae. albopictus‐infested areas. We performed an experimental oral infection with the Asian genotype of ZIKV in Ae. albopictus from La Réunion and foun...

Co ‐occurrence and seasonal and environmental distributions of the sandflies Lutzomyia longipalpis and Nyssomyia whitmani in the city of Puerto Iguazú, northeastern Argentina
Abstract
The aim of this work was to study the distribution of Phlebotominae (Diptera: Psycodidade) abundance in time and space in an area in northeastern Argentina with vector transmission of visceral and tegumentary leishmaniasis. For this, 51 households were selected using a ‘worst scenario’ criterion where one light trap was set during two consecutive nights in peridomiciles in the transitions between the four seasons, and the environment was surveyed simultaneously. The relationships of phlebotomine assemblage structure and the most abundant species with seasonality and environmental variables were evaluated using...

Insecticide susceptibility status in Mexican populations of Stegomyia aegypti (= Aedes aegypti): a nationwide assessment
Abstract
In Mexico, mosquito vector‐borne diseases are of public health concern as a result of their impact on human morbidity and mortality. The use of insecticides against adult mosquitoes is one of the most common ways of controlling mosquito population densities. However, the use of these compounds has resulted in the development of insecticide resistance. The aim of this study was to estimate susceptibility to six pyrethroids, two carbamates and two organophosphates in Mexican populations of Stegomyia aegypti (Linnaeus, 1762) (= Aedes aegypti) (Diptera: Culicidae) mosquitoes. Bottle insecticide susceptibility test...
