Longitudinal monitoring of anti ‐saliva antibodies as markers of repellent efficacy against Phlebotomus perniciosus and Phlebotomus papatasi in dogs
Dogs naturally exposed toLeishmania vectors, the sandfliesPhlebotomus perniciosus andPhlebotomus papatasi, and treated preventively with sandfly repellents developed antibodies against the insects' salivary proteins. Anti ‐P. perniciosus and ‐P. papatasi saliva antibody concentrations were low, which suggests the repellent limited sandfly bites and is useful in canine leishmaniasis control. Longitudinal monitoring of anti ‐saliva antibodies is a good method of marking insect repellent efficacy againstP. perniciosus andP. papatasi in dogs. AbstractA 2 ‐year longitudinal study of enzyme‐linked immunosorbent assay (...

Fewer Scientists Are Studying Insects. Here ’s Why That’s So Dangerous
In the summer of 2016, Jerome Goddard, a medical entomologist in Mississippi, received an email from the U.S. Centers for Disease Control and Prevention (CDC) with a desperate ask. The agency was conducting an “urgent” search for insect scientists around the U.S. who could take up to a six-month paid leave from work to help the CDC fight the Zika outbreak in the U.S., and possibly respond to areas with local transmission if needed. “That’s how bad it is—they need to borrow someone,” says Goddard, an extension professor of medical entomology at Mississippi State University. “We can&...

Falciparum Malaria Outbreak in Sabah Linked to an Immigrant Rubber Tapper.
In conclusion, an outbreak of P. falciparum malaria was introduced into a malaria-free village by a migrant rubber tapper, by whom the imported parasite was introduced to the community via vector Anopheles balabacensis. Living near stagnant water bodies was the risk factor in this outbreak. PMID: 29141714 [PubMed - as supplied by publisher]

Molecular detection of Wolbachia pipientis in natural populations of sandfly vectors of Leishmania infantum in endemic areas: first detection in Lutzomyia longipalpis
Abstract A polymerase chain reaction‐based method was used to screen sandflies for infection with Wolbachia (Rickettsiales: Rickettsiaceae), an intracellular bacterial endosymbiont found in many arthropods and filarial hosts. Positive results were obtained in five of 200 field‐collected sandflies and were confirmed by sequencing. All sandflies were Lutzomyia longipalpis (Diptera: Psychodidae) captured in a region endemic for visceral leishmaniasis in Brazil. This is the first study to identify Wolbachia infection in this Lutzomyia species, which is the main vector of leishmaniasis in the study area. The low infection r...

Assessment of the Probability of Autochthonous Transmission of Chikungunya Virus in Canada under Recent and Projected Climate Change
This study identifies that southern Canada may be the very northern limit for transmission of these pathogens with climate change. Other factors need to be explored however, which include understanding when and where Canadian travelers are likely to return, infrastructure in Canada that may support vector populations in what would be expected to be climatically unsuitable regions, and whether or not there are other competent vectors in Canada. Further research to close the gap on our current understanding of CHIKV and CHIKV vectors, improved surveillance on Ae. albopictus in North America, and enhanced climate projection m...

Studies on the behaviour and control of phlebotomine sandflies using experimental houses
Abstract Programmes for the control of phlebotomine sandflies (Diptera: Psychodidae), the vectors of leishmaniases, mainly target adults because larval breeding sites are generally unknown or inaccessible. To determine how blood‐questing sandfly females enter homes and to develop means for their control, an experimental house (EH) was constructed in a village endemic for cutaneous leishmaniasis. Initially, carbon dioxide (CO2)‐baited suction traps were installed inside the EH to attract and capture sandflies. For other experiments, the windows of the EH were fitted with CO2‐baited window entrance traps (WETs) that al...

Diversity of Triatominae (Hemiptera: Reduviidae) in Santander, Colombia: Epidemiological implications.
CONCLUSIONS: Results revealed differences in the diversity of the two regions and the potential of wild species to occupy artificial ecotopes. Triatomines intrusion and the recent involvement of wild species in the transmission of Trypanosoma cruzi emphasize the need to further investigate the ecology of these vectors in order to guide population control strategies.

Phlebotomine sandfly ecology on the Indian subcontinent: does village vegetation play a role in sandfly distribution in Bihar, India?
Abstract Visceral leishmaniasis (VL) is a disease that results in approximately 50 000 human deaths annually. It is transmitted through the bites of phlebotomine sandflies and around two‐thirds of cases occur on the Indian subcontinent. Indoor residual spraying (IRS), the efficacy of which depends upon sandfly adults resting indoors, is the only sandfly control method used in India. Recently, in Bihar, India, considerable sandfly numbers have been recorded outdoors in village vegetation, which suggests that IRS may control only a portion of the population. The purpose of this study was to revisit previously published res...

Spatial Distribution of Phlebotomine Sand Fly Species (Diptera: Psychodidae) in Qom Province, Central Iran
Zoonotic cutaneous leishmaniasis (ZCL) is transmitted to humans by phlebotomine sand fly bites. ZCL is a major health problem in Iran, where basic knowledge gaps about sand fly species diversity persist in some ZCL-endemic areas. This paper describes the richness and spatial distribution of sand fly species, collected with sticky traps, in Qom province, a ZCL-endemic area in central Iran, where sand fly fauna has been poorly studied. Collected species were mapped on urban and rural digital maps based on a scale of 1/50,000. All analyses were undertaken with rural- and urban-level precision, i.e., rural and urban levels wer...
