BACKGROUND Orussus minutus is an uncommonly collected parasitoid sawfly known from the eastern United States. NEW INFORMATION We report specimens Orussus minutus Middlekauff, 1983, from Arkansas, Iowa, Minnesota, and Manitoba, which represent new state and province records and significantly expand the known range of the species west from previous records; provide collection information for un...

Fecal samples from 155 mantled howling monkeys (Alouatta palliata palliata) examined at Centro Ecologico La Pacifica, Guanacaste Province, Costa Rica, revealed 75 (48%) had parasitic infections. A sampling of nine howling monkeys from Santa Rosa National Park. Costa Rica indicated only one infected animal (11%). Only three of 19 (16%) spider monkeys (Ateles geoffroyi) also from Santa Rosa were ...

A total of 489 small mammals belonging to seven species captured in Lithuania during 2013-2014 were investigated for Rickettsia pathogens. The overall prevalence of Rickettsia spp. was 27.6%, with a higher prevalence detected in Micromys minutus (45.9%), followed by Apodemus flavicollis (29.4%), Sorex araneus (25%) and Myodes glareolus (23.7%). Sequence analysis of the gltA gene and the 17 kDa ...

During a survey of fungal diversity of the order Mucorales, three zygomycete isolates, CNUFC-YR113-1, CNUFC-KNU16-7, and CNUFC-BS1-1 were isolated from freshwater and soil samples in Korea. The strains were analyzed both morphologically and phylogenetically based on internal transcribed spacer and 28S rDNA gene sequences. Based on their morphology and phylogeny, the CNUFC-YR113-1 and CNUFC-KNU1...

The biological control program for diffuse knapweed, Centaurea diffusa Lamarck, a Eurasian plant that has invaded large areas of grasslands in western North America, has gone on for over 35 years. This program involved the release of 12 biological control agents of which four are numerous and widely distributed; two species of Tephritid flies, Urophora affinis and Urophora quadrifasciata, the r...

Global warming may affect species abundance and distribution, as well as temperature-dependent morphometric traits. In this study, we first used historical data to document changes in Orius (Heteroptera: Anthocoridae) species assemblage and individual morphometric traits over the past seven decades in Israel. We then tested whether these changes could have been temperature driven by searching f...

The data presented in this paper were obtained to define more accurately the environment of Polymorphus minutus, an acanthocephalan parasite of ducks. This parasite inhabits a region of the duck's intestine extending from 60% to 80% of the intestinal length (Crompton & Whitfield, 1968). In the case of Momliformis dubius, an acanthocephalan parasite of rats, Edmonds (1965) found that nutrients a...

Many of the attempts to culture intestinal helminths in vitro appear to have been made with relatively little knowledge of the physico-chemical conditions which occur in the alimentary tract of vertebrates. For example, only a few measurements have been made on the osmotic pressure of the contents of the intestinal lumen and even fewer have been made on the degree of variation of the osmotic pr...
