Proc Natl Acad Sci U S A 99:7508-13. 2002..7 +/- 10 million years ago. This range provides an upper bound on the time during which these wasps and viruses have been functionally associated...
- Reared microgastrine wasps (Hymenoptera: Braconidae) from Yanayacu Biological Station and environs (Napo Province, Ecuador): diversity and host specializationJames B Whitfield
Entomology Department, University of Illinois, Urbana, IL 61801, USA
J Insect Sci 9:31. 2009..An annotated list of microgastrine genera not yet recorded at Yanayacu, but which we expect to eventually find there based on extrapolation from their known geographic distributions, is provided...
- Ancient rapid radiations of insects: challenges for phylogenetic analysisJames B Whitfield
Department of Entomology, University of Illinois, Urbana, IL 61821, USA
Annu Rev Entomol 53:449-72. 2008..At least some historical patterns of divergence may, however, continue to defy our attempts to completely reconstruct them with confidence, at least using current strategies...
- Deciphering ancient rapid radiationsJames B Whitfield
Department of Entomology, 320 Morrill Hall, 505 S Goodwin Ave, University of Illinois, Urbana, IL 61801, USA
Trends Ecol Evol 22:258-65. 2007..Here, we review the underlying causes of difficulty in determining the branching patterns of diversification in ancient rapid radiations, and review novel data exploration tools that can facilitate understanding of these radiations...

Department of Entomology, University of Illinois, Urbana, IL 61801, USA
J Insect Physiol 49:397-405. 2003..Ongoing sequencing studies of entire PDV genomes from diverse wasp species are likely to greatly contribute to our understanding of PDV evolution...

- Dissecting the ancient rapid radiation of microgastrine wasp genera using additional nuclear genesJonathan C Banks
Department of Entomology, University of Illinois Urbana Champaign, 505 S Goodwin Avenue, Urbana, IL 61801, USA
Mol Phylogenet Evol 41:690-703. 2006..Our results suggest that, in some cases, combining morphological and genetic characters may be the most practical way to increase support for short branches deep in a phylogeny...
- A key to new world distatrix mason (Hymenoptera: Braconidae), with descriptions of six new reared neotropical speciesChristopher C Grinter
Department of Entomology, University of Illinois, Urbana, Illinois, 61801 USA
J Insect Sci 9:29. 2009..The new discoveries expand our knowledge of the World's widespread Distatrix fauna by about a third, suggesting that similar survey efforts in other poorly sampled regions will reveal numerous additional undescribed species...
- Experimental support for multiple-locus complementary sex determination in the parasitoid Cotesia vestalisJetske G de Boer
Department of Entomology, University of Minnesota, St Paul, Minnesota 55108, USA
Genetics 180:1525-35. 2008..Our data visually resemble CSD with linked loci because diploid male production in the second generation was lower than that in the first. To our knowledge, our data provide the first experimental support for ml-CSD...

Australian Centre for Evolutionary Biology and Biodiversity, School of Earth and Environmental Science, The University of Adelaide, SA 5005, Australia
Mol Phylogenet Evol 47:378-95. 2008..It is hypothesized that the different parasitism strategies of subfamilies (Chelonines are egg parasitoids and the remainder are larval parasitioids) may have influenced the evolutionary rates of the groups...
