Based on examination of the type specimens and additional material from various localities, Acinopus lepeletieri Lucas, 1846 is treated as a distinct species from Algeria and Tunisia, not as a synonym of A. sabulosus (Fabricius, 1792). The distinctive features of these two species and their distribution are described. The absence of any newly collected material of A. lepeletieri argues for the ...

An outbreak of encephalitis due to West Nile (WN) virus occurred in New York City and the surrounding areas during 1999. Mosquitoes were collected as part of a comprehensive surveillance program implemented to monitor the outbreak. More than 32,000 mosquitoes representing 24 species were tested, and 15 WN virus isolates were obtained. Molecular techniques were used to identify the species repre...

Three species of Caribbomerus Vitali are newly recorded for the Dominican Republic: Caribbomerus decoratus (Zayas), Caribbomerus elongatus (Fisher), and Caribbomerus asperatus (Fisher). The first two also represent first records for Hispaniola. Caribbomerus elongatus (Fisher) is redescribed based on additional material, including the first known males. Caribbomerus similis (Fisher) is newly rec...

INTRODUCTION The burden of chronic diseases is rapidly increasing worldwide. In Australia rural populations have a greater burden of disease. Chronic diseases are largely preventable with diet as a key risk factor. With respect to diet-related chronic disease, dietary risk may be due to poor food access, namely, poor availability and/or the high cost of healthy food. It is likely that poor food...

A comprehensive study of geomagnetic field variations has been carried out at the dip equatorial latitudes of West Africa. The data obtained during the 1993 French participation in the International Equatorial Electrojet Year experiment in Africa was used for the analysis. Only the quiet condition was examined. Variation in the three geomagnetic field elements (H, D, and Z) showed more variabil...

BACKGROUND Social-ecological resilience refers to the dynamic process of adaptive learning, reorganization and meaning-making demonstrated in linked human, animal, and plant ecosystems often organized in formal and/or informal social institutions, as they anticipate, withstand and/or judiciously engage with adversity while maintaining function without fundamentally losing their identity. OBJE...

Twelve Hartmann's mountain zebra, Equus zebra hartmannae, were shot for arthropod parasite recovery during the period June 1980-June 1981 on a farm in the Khomas Hochland region of South West Africa/Namibia. Four species of Gasterophilus larvae, 1 species of Rhinoestrus larvae and 3 ixodid tick species were recovered. The seasonal prevalence of the Gasterophilus species larvae and of Rhipicepha...

In this paper we present new evidence of cross-border shopping in response to sales taxation. While several instructive studies provide estimates of the cross-border shopping effect, we utilize a unique opportunity to evaluate the effect of a large discrete change in sales tax policy. Using county level data on food income and sales tax data for West Virginia over the 1982-2000 period we estima...

The objective of this study was to conduct a preliminary survey of diseases that might be present in the wild Nile crocodile population in the Okavango Delta, Botswana. Blood samples were collected from crocodiles ranging in size from 34.0 cm to 463.0 cm total length. Samples were examined for blood parasites and underwent a haematological analysis. Before release the crocodiles were examined f...

Psoquilla infuscata Badonnel, previously known from a single locality in coastal West Africa, is recorded from southern Mexico, Belize, Panamá, Suriname, and Perú. The original description is based entirely on macropterous females, while our material includes brachypterous forms of both sexes as well as macropterous specimens. Augmented descriptions of adults of this species and its only congen...
