In 2006, we examined the flight responses of 43 species of longhorn beetles (Coleoptera: Cerambycidae) to multiple-funnel traps baited with binary lure blends of (1) ipsenol + ipsdienol, (2) ethanol + alpha-pinene, and a quaternary lure blend of (3) ipsenol + ipsdienol + ethanol + alpha-pinene in the southeastern United States. In addition, we monitored responses of Buprestidae, Elateridae, and...

Two new species of the genus Hydrometra Latreille, 1796, are described from the Oriental Region. Hydrometra cherukolensis sp. nov. is described from Kanyakumari District, Tamil Nadu, India, belongs to the Hydrometra julieni species group, and is closely related to H. julieni Hungerford & Evans, 1934 and H. julienoidea Polhemus & Polhemus, 1995. Hydrometra nicobarensis sp. nov. is described from...

Five traditionally used antidiabetic native medicinal plants of Mauritius, namely, Stillingia lineata (SL), Faujasiopsis flexuosa (FF), Erythroxylum laurifolium (EL), Elaeodendron orientale (EO), and Antidesma madagascariensis (AM), were studied for possible α -amylase and α -glucosidase inhibitory property, glucose entrapment, and amylolysis kinetics in vitro. Only methanolic extracts of EL, E...

The Island of Martin Garcia lies at the confluence of the Uruguay and Paraná Rivers (upper Río de la Plata). This island is an outcrop of the crystalline basement. Due to basalt exploitation the island exhibits several ponds covered by carpets of free-floating macrophytes. Seven major environmental variables were measured: water and air temperature, percentage of oxygen saturation, dissolved ox...

A single-round polymerase chain reaction (PCR) diagnostic assay was developed from a small subunit ribosomal DNA (SSU rDNA) gene sequence to detect the myxozoan parasite Kudoa neurophila, the causative agent of myxozoan disease in the hatchery reared marine finfish, striped trumpeter Latris lineata (Forster). The assay was developed for use as a disease control management tool in a hatchery sys...

A total of 239 individuals of 50 bird species were examined for chewing lice (Insecta: Phthiraptera) in southern Vietnam. Fifty-six birds of 20 species were parasitised by 15 species of lice belonging to 10 genera from two suborders, Amblycera: Menacanthus, Meromenopon, Myrsidea, and Ischnocera: Alcedoecus, Brueelia, Cuculicola, Meropoecus, Penenirmus, Philopteroides and Philopterus. Thirteen l...

The evolution of warning coloration (aposematism) has been difficult to explain because rare conspicuous mutants should suffer a higher cost of discovery by predators relative to the cryptic majority, while at frequencies too low to facilitate predator aversion learning. Traditional models for the evolution of aposematism have assumed conspicuous prey phenotypes to be genetically determined and...
