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...

Let G be a simple and simply connected complex Lie group, g its Lie algebra. In the following, I remove the restriction “G is of classical type or G2” made on G in the papers of Beauville, Laszlo and myself [L-S],[B-L-S] on the moduli of principal G-bundles on a curve. As I will just “patch” the missing technical points, this note should be seen as an appendix to the above cited papers. Let MG,...

This paper explores the effects of monetary shocks on the allocation of factors of production. We analyze these effects when money plays a role in improving the timing of the transactions undertaken by entrepreneurs. Such improvement is facilitated by money’s important role in providing liquidity to entrepreneurs. Using a model in which production processes take time to mature and where credit ...
