The effects of three sulfur products (calcium polysulfide [= lime sulfur], dry flowable sulfur, and ammonium thiosulfate, a plant nutrient), were tested in bioassays against a predatory mite, Galandromus occidentalis (Nesbitt), and two species of tetranychid (pest) mites, twospotted spider mite (Tetranychus urticae Koch) and European red mite [Panonychus ulmi (Koch)]. Calcium polysulfide and am...

Hamulonema gen. nov. is proposed for Teladorsagia hamata and Ostertagia kenyensis in the ostertagiine nematode fauna found in artiodactyl hosts from Africa. Monomorphic species representing this genus are characterized by a bilaterally symmetrical and parallel synlophe in males and females, a 2-2-1 bursal formula, an accessory bursal membrane that is strongly cuticularized and reduced, a strong...

A 2 year study was conducted to evaluate the effects of first-season strategic or tactical treatments with ivermectin on trichostrongylosis in heifer calves in the first and second-season grazing. Three groups of each eight Holstein-Friesian calves were turned out in early May onto a permanent pasture naturally contaminated with trichostrongyle larvae. Two of these groups were given ivermectin ...

Telfairia occidentalis Hook. f., Cucurbitaceae, is a leafy vegetable used in soup and folk medicine in southern Nigeria. This study was conducted to investigate the anxiolytic and sedative activities of the hydroethanolic extract of the leaves of T. occidentalis in mice. The hole-board, elevated plus maze, open-field, light-dark, and social interaction tests were used in this study. T. occident...

The prevalence of helminthiasis was found to be 15.2 % in buffaloes. Out of 500 samples examined, 9.2 % and 5.4 % were infected with nematodes and trematodes respectively. Mixed infection was observed in 0.6 %. The chief helminths identified were: Toxocara vitulorum (3.6 %), Fasciola gigantica (3.2 %) Oesophagostomum radiatum (3.0 %) Strongyloides papillosus (2.4 %), Fasciola hepatica (2.2 %), ...

Human activities have continuously increased the level of heavy metal ions circulating in the environment. It is important to understand the tolerance of plant species to high concentrations of heavy metals. Very little is known on the response of Eucalyptus species to Zn and Cu toxic concentrations Eucalyptus camaldulensis, E. microtheca, and E. occidentalis seeds were grown in silt and irriga...

Since the mid-1990s, Bombus occidentalis (Green) has declined from being one of the most common to one of the rarest bumble bee species in the Pacific Northwest of the United States. Although its conservation status is unresolved, a petition to list this species as endangered or threatened was recently submitted to the U.S. Fish and Wildlife Service. To shed light on the conservation situation ...
