Hymenopteran Parasitoids on Fruit-infesting Tephritidae (Diptera) in Latin America and the Southern United States: Diversity, Distribution, Taxonomic Status and their use in Fruit Fly Biological…
The most pressing needs related to fruit fly biological control in areas of the Neotropics where fruit fly populations severely restrict the development of commercial fruit growing are discussed.
Climatological observations and predicted sublimation rates at Lake Hoare, Antarctica.
The first year-round observations available for any site in Taylor Valley are reported on and a model incorporating nonsteady molecular diffusion into Kolmogorov-scale eddies in the interfacial layer and similarity-theory flux-profiles in the surface sublayer, is used to determine the rate of ice sublimation from the acquired meteorological data.
Key to and status of opiine braconid (Hymenoptera) parasitoids used in biological control of Ceratitis and Dacus s.l. (Diptera: Tephritidae).
A key is presented to the 42 species of opiine Braconidae previously collected in biological control programs directed against Ceratitis and Dacus s. l. Diagnostic features and present nomenclatural…
Viruses in Antarctic lakes
Water samples collected from four perennially ice-covered Antarctic lakes during the austral summer of 1996-1997 contained high densities of extracellular viruses, indicating that viral lysis may be a major factor in the regulation of microbial populations in these extreme environments.
Parasitoids of medfly, Ceratitis capitata, and related tephritids in Kenyan coffee: a predominantly koinobiont assemblage.
Most of the parasitoid species recovered during this study are capable of developing on C. capitata, while several also attack C. rosa, one of the notorious pests of tropical and subtropical fruits.
Physical Controls on the Taylor Valley Ecosystem, Antarctica
Lake Hoare, Antarctica: sedimentation through a thick perennial ice cover.

Sediment traps retrieved from the lake bottom indicate that rates of deposition can vary by large amounts over lateral scales as small as 1 m, and the poor stratigraphic correlation that is observed indicates substantial lateral variability in sedimentation rate.
Cryoconite holes on glaciers.
Cryoconite holes are water-filled depressions on the surface of glaciers. They contain microbial communities and may contribute to glacial wastage and biological colonization of ice-free areas.
