The Culicoides (Diptera: Ceratopogonidae) of Belize, Central America

The Culicoides fauna of Belize is poorly known, and until 197 4 only 3 species were recorded. Nineteen species of Culicoides from Belize were identified from six collection sites: C. barbosai Wirth & Blanton, C. crepuscularis Malloch, C. debilipalpis Lutz, C. diabolic us Hoffman, C. foxi Ortiz, C. furens (Poey), C. gabaldoni Ortiz, C. heliconiae Fox & Hoffman, C. hoffmani Fox, C. imitator Ortiz, C. insignis Lutz, C. jamaicensis Edwards, C. leopoldoi Ortiz, C. limai Barretto, C. paraensis (Goeldi), C. pifanoi Ortiz, C. pusilloides Wirth & Blanton, C. pusillus Lutz, and a new species, C. mckeeveri Brickle & Hagan is described and illustrated

A Small Target Neutrino Deep-Inelastic Scattering Experiment at the First Muon Collider

Several different scenarios for neutrino scattering experiments using a neutrino beam from the muon collider complex are discussed. The physics reach of a neutrino experiment at the front end of a muon collider is shown to extend far beyond that of current neutrino experiments, since the high intensity neutrino beams one would see at the muon collider allow for a large flexibility in choosing neutrino targets. Measurements of quark spin, A-dependence of the structure function $xF_3$ and neutral current chiral couplings to quarks are outlined.Comment: 7 pages, 2 figures, to appear in the proceedings of the Workshop on Physics at the First Muon Collider and at the Front End of a Muon Collider, November 1997, Fermila

Aggregation Behavior of a Willow Flea Beetle, \u3ci\u3eAltica Subplicata\u3c/i\u3e (Coleoptera: Chrysomelidae)

This study examined the aggregation behavior of a specialist insect herbivore, Altica subplicata (Coleoptera: Chrysomelidae), on its host plant, Salix cordata. Mark-recapture experiments were conducted in patches of S. cordata growing along the shores of Lake Huron. Beetles aggregated on individual host plants, but did not aggregate in larger areas containing many host plants. Plants colonized by marked beetles had significantly higher abundances of unmarked beetles than did plants that were not colonized by marked beetles. Experimental manipulations of the number of beetles present on plants showed that colonization rates by marked beetles were higher on plants with conspecifics than on plants which had all beetles removed the previous day. The sex of beetles, however, did not influence colonization behavior; both male and female beetles colonized plants regardless of the sex of beetles already present on plants. These results are discussed with respect to possible explanations for aggregation, and the role of aggregation and movement in influencing insect distributions

Laboratory Rearing of \u3ci\u3eLycaeides Melissa Samuelis\u3c/i\u3e (Lepidoptera: Lycaenidae), An Endangered Butterfly in Michigan

The Karner blue butterfly (Lycaeides melissa samuelis) is listed as a federally endangered species in the United States. It occurs in oak savanna and pine barren habitats from eastern Minnesota to New Hampshire. In 1994, we successfully reared Karner blue larvae under controlled laboratory conditions for experimental purposes, and report on those rearing methods here. We collected 20 female Karner blue adults of the spring generation from two areas in Michigan, and housed them in cages in an environmental chamber at 240 -26°C for 5 days. The female butterflies produced 154 eggs, of which 72 hatched in an average of 4.5 days, and 68 first instars survived. Eggs, larvae and pupae were kept in a growth chamber at 24°C. Developmental time from egg to adult averaged 26 days; the average duration of each instar ranged from 3 to 4 days, and the average pupal duration was 8 days. Thirty three lab- oratory-reared Karner blue larvae successfully completed the 4 instars, and were released as adults into maternal collection sites. Laboratory rearing may be a viable means of providing Karner blue individuals for reintroduction into areas where the species is extirpated, for supplementation of small populations, or for research. Ultimately, such methods may become an integral part in the recovery of this and other rare invertebrate species

Fermi Condensates

Ultracold atomic gases have proven to be remarkable model systems for exploring quantum mechanical phenomena. Experimental work on gases of fermionic atoms in particular has seen large recent progress including the attainment of so-called Fermi condensates. In this article we will discuss this recent development and the unique control over interparticle interactions that made it possible.Comment: Proceedings of ICAP-2004 (Rio de Janeiro).
