The genera Tenupedunculus Schultz, 1982 and Stenobermuda Schultz, 1979 are recorded for the first time from beyond the Southern Ocean, at the Great Barrier Reef, Australia. Tenupedunculus serrulatussp. n. and Stenobermuda waroogasp. n. are described from Heron Island and Lizard Island respectively, both in the Great Barrier Reef. The genus Tenupedunculus is revised and a new diagnosis presented...

Behavioral tactics play a crucial role in the evolution of species and are likely to be found in host-parasitoid interactions where host quality may differ between host developmental stages. We investigated foraging decisions, parasitism and related fitness in a gregarious ectoparasitoid, Sclerodermus harmandi in relation to two distinct host developmental stages: larvae and pupae. Two colonies...

The effects of biotic and abiotic factors on stem borer parasitoid diversity, abundance, and parasitism were studied in cultivated and natural habitats in four agroecological zones in Kenya. Comparing habitat types, we found partial support for the "natural enemy" hypothesis, whereby, across all localities, parasitoid diversity was higher in more diverse host plant communities in natural habita...

Department of Entomology, University of California, Davis, heim and Hongkham 1996). Multiple egg clutches may California 95616 be selected for if the additional eggs serve as ‘‘insurance eggs,’’ thereby increasing the probability that one offSubmitted November 10, 1997; Accepted May 19, 1998 spring will successfully emerge from a host (Rosenheim 1993; Rosenheim and Hongkham 1996). Once multiple...

A large number of repeats of a satellite DNA (stDNA) family have been cloned and sequenced from species and populations of the genus Pimelia (Tenebrionidae, Coleoptera). The beetles were collected in the Canary Islands, Morocco, the Iberian Peninsula, and the Balearic Islands in order to analyze the evolutionary forces and processes acting on abundant stDNAs conserved at the genus level. This r...

The response to intra- and interspecific faecal assembling signals was tested in Rhodnius prolixus. Papers impregnated with excrement of R. prolixus induced the aggregation of larvae of this species, but also of those of Triatoma infestans. However, faeces belonging to T. infestans were not able to assemble larvae of R. prolixus. On the other hand, there was no response of R. prolixus to putati...

Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae), a gregarious larval endo-parasitoid, is one of three biocontrol agents from Asia currently being released in the United States to combat the invasive emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae). The current protocol for rearing T. planipennisi involves presenting the wasps with artificially infested ash sti...

A major obstacle to part-of-speech (=POS) tagging of Northern Sotho (Bantu, S 32) are ambiguous function words. Many are highly polysemous and very frequent in texts, and their local context is not always distinctive. With certain taggers, this issue leads to comparatively poor results (between 88 and 92 % accuracy), especially when sizeable tagsets (over 100 tags) are used. We use the RF-tagge...

Generalised obesity is increasing in prevalence globally, however trends in abdominal obesity are less well known. In 2003, 1,999 women of childbearing age participated in the Croatian Adult Health Survey, of whom 598 (29.9%) participated in the second cycle in 2008. For 2008, the prevalence of abdominal obesity using the International Diabetes Federation (IDF) criterion (waist circumference > ...

Raw buffalo milk samples from the agroindustrial zone in upper Egypt were analyzed for the presence of organochlorine and organophosphorus pesticides using gas chromatography-mass spectroscopy. Five organochlorine pesticides namely, alachlor, dieldrin, hexachlorobenzene, lindane and methoxychlor and three organophosphorus pesticides chlorpyrifos, malathion, and parathion-methyl were detected in...
