Eave ribbons treated with the spatial repellent, transfluthrin, can effectively protect against indoor-biting and outdoor-biting malaria mosquitoes.

Malar J 2018 Oct 17;17(1):368. Epub 2018 Oct 17.

Environmental Health and Ecological Sciences Department, Ifakara Health Institute, Ifakara, Tanzania.

Background: Long-lasting insecticide-treated nets and indoor residual spraying protect against indoor-biting and indoor-resting mosquitoes but are largely ineffective for early-biting and outdoor-biting malaria vectors. Complementary tools are, therefore, needed to accelerate control efforts. This paper describes simple hessian ribbons treated with spatial repellents and wrapped around eaves of houses to prevent outdoor-biting and indoor-biting mosquitoes over long periods of time.

Impact of Consumption of Bananas on Attraction of to Humans.

Insects 2018 Sep 28;9(4). Epub 2018 Sep 28.

Department of Entomology, University of Wisconsin, Madison, WI 53706, USA.

Humans vary in attractiveness to mosquitoes, a phenomenon that is largely attributed to differences in physical cues such as heat and volatile odors emanating from breath and skin. Diet can change human odors but whether specific dietary components alter host attractiveness is largely unexplored. We identified bananas as a target for study following a survey of the internet for advice on avoiding mosquito bites. Read More

Breakfast, lunch, and dinner sign: a hallmark of flea and bedbug bites.

An Bras Dermatol 2018 Sep-Oct;93(5):759-760

Department of Dermatology and Radiotherapy, Faculdade de Medicina de Botucatu, Universidade Estadual Paulista, Botucatu (SP), Brazil.

Human, dog, and cat fleas, as well as bedbugs, feed by biting their victims, causing acute prurigo, which is aggravated in sensitized victims (papular urticaria). The lesions appear in the classic "breakfast, lunch, and dinner" pattern. There are two main explanations: the parasites "map" the skin area in search of the best places to bite, and their removal when victim scratches, and then reattach to the skin. Read More

A highly secure method for rearing mosquitoes.

Trop Med Health 2018 23;46:16. Epub 2018 May 23.

1Department of Tropical Medicine, The Jikei University School of Medicine, Tokyo, Japan.

Background: Vector-borne infectious diseases are caused by pathogenic microorganisms transmitted mainly by blood-sucking arthropod vectors. In laboratories, the handling of insects carrying human pathogens requires extra caution because of safety concerns over their escape risk. Based on standard insect containment practices, there have been cases where costly enhancements were required to definitely protect laboratory workers and neighbors from potential infection through mosquito bites.

Modelling the impact of larviciding on the population dynamics and biting rates of Simulium damnosum (s.l.): implications for vector control as a complementary strategy for onchocerciasis elimination in Africa.

Parasit Vectors 2018 May 29;11(1):316. Epub 2018 May 29.

MRC Centre for Outbreak Analysis and Modelling, Department of Infectious Disease Epidemiology, School of Public Health, Faculty of Medicine (St Mary's campus), Imperial College London, Norfolk Place, London, W2 1PG, UK.

Background: In 2012, the World Health Organization set goals for the elimination of onchocerciasis transmission by 2020 in selected African countries. Epidemiological data and mathematical modelling have indicated that elimination may not be achieved with annual ivermectin distribution in all endemic foci. Complementary and alternative treatment strategies (ATS), including vector control, will be necessary. Read More

Aedes communis Reactivity Is Associated with Bee Venom Hypersensitivity: An in vitro and in vivo Study.

Int Arch Allergy Immunol 2018 22;176(2):101-105. Epub 2018 May 22.

Ambulatorio di Allergologia, Clinica San Carlo, Paderno Dugnano, Milan, Italy.

Mosquito bite is usually followed by a local reaction, but severe or systemic reaction may, in rare cases, occur. Allergic reactions to Aedes communis (Ac) may be underestimated due to the lack of reliable diagnostic tools. In this multicenter study, 205 individuals reporting large local reactions to Ac were enrolled and studied for cutaneous or IgE reactivity to Ac, Blattella germanica, Penaeus monodon, and Dermatophagoides pteronyssinus.

Clinical consequences of toxic envenomations by Hymenoptera.

Authors:
Justin O Schmidt

Toxicon 2018 Aug 19;150:96-104. Epub 2018 May 19.

Southwestern Biological Institute, 1961 W. Brichta Drive, Tucson, AZ 85745, USA. Electronic address:

Many familiar Hymenoptera are brightly colored and can sting painfully-thus, their threat and clinical importance may be exaggerated. Most stinging insects only sting to defend themselves or their colonies from predators. The clinical nature of Hymenoptera envenomations contrasts that of other venomous animals, including other arthropods, primarily because allergic reaction, not direct intoxication, is the usual main concern.

In vitro comparison of three common essential oils mosquito repellents as inhibitors of the Ross River virus.

PLoS One 2018 17;13(5):e0196757. Epub 2018 May 17.

Université de la Réunion, UM 134 Processus Infectieux en Milieu Insulaire Tropical (PIMIT), INSERM U1187, CNRS UMR9192, IRD UMR249, Plateforme Technologique CYROI, Sainte Clotilde, France.

Background: The essential oils of Cymbopogon citratus (CC), Pelargonium graveolens (PG) and Vetiveria zizanioides (VZ) are commonly used topically to prevent mosquito bites and thus the risk of infection by their vectored pathogens such as arboviruses. However, since mosquito bites are not fully prevented, the effect of these products on the level of viral infection remains unknown.

Objectives: To evaluate in vitro the essentials oils from Reunion Island against one archetypal arbovirus, the Ross River virus (RRV), and investigate the viral cycle step that was impaired by these oils. Read More

Mosquito saliva alone has profound effects on the human immune system.

PLoS Negl Trop Dis 2018 05 17;12(5):e0006439. Epub 2018 May 17.

Department of Molecular Virology and Microbiology, Baylor College of Medicine, Houston, Texas, United States of America.

Mosquito saliva is a very complex concoction of >100 proteins, many of which have unknown functions. The effects of mosquito saliva proteins injected into our skin during blood feeding have been studied mainly in mouse models of injection or biting, with many of these systems producing results that may not be relevant to human disease. Here, we describe the numerous effects that mosquito bites have on human immune cells in mice engrafted with human hematopoietic stem cells. Read More

Pyrethroid insecticides maintain repellent effect on knock-down resistant populations of Aedes aegypti mosquitoes.

PLoS One 2018 15;13(5):e0196410. Epub 2018 May 15.

Department of Epidemiology, University of North Carolina Gillings School of Global Public Health, Chapel Hill, North Carolina, United States of America.

Pyrethroid-treated clothing is commonly worn for protection against mosquitoes; pyrethroids are both insecticides and repellents. Pyrethroid resistance has become increasingly common in Aedes aegypti, the vector of dengue, Zika, and other arboviruses, but it is not clear whether resistance is associated with reductions in repellency. In order to determine whether long-lasting permethrin impregnated (LLPI) clothing is protective, we used Aedes aegypti from New Orleans, LA (pyrethroid-sensitive) and San Juan, PR (resistant) to measure both lethality and repellency.

Safety and Efficacy of a Progressively Prolonged Maintenance Interval of Venom Immunotherapy.

Int Arch Allergy Immunol 2018 12;176(1):39-43. Epub 2018 Apr 12.

Allergology Department, Laikon General Hospital, Athens, Greece.

Background: The long-term protection provided by venom immunotherapy (VIT) is related to the dose administered and to its long duration; the latter, however, becomes inconvenient for patients in countries like Greece, with many islanders or inhabitants of distant mountainous areas. Maintenance interval prolongation reduces the number of office visits - saving time and money - and as a consequence contributes to the patients' compliance. The aim of this prospective study was to evaluate the safety and efficacy of VIT on a progressively prolonged maintenance interval (PPMI). Read More
