"Even more than organic production, IPM strives to use the best scientific practices to ensure safe and sustainable agricultural systems. To do this, IPM incorporates practices from conventional and organic production methods, and even biotechnology, a method that has been turned into a bogeyman, but in reality is safer for humans and the environment. IPM has been a national policy for the United States since 1993 and its implementation has resulted in dramatic decreases in the use of harmful pesticides. Much of this decrease has been due to the use of crops produced through biotechnology. As an entomologist whose goal is to develop insect management programs that protect the crop and the environment, I routinely test organic, conventional and biotech practices. " Read more

Larval Debris-Carrying In Green Lacewings: Patterns And Evolution
Mar 18, 2014
The March issue of the Annals of the Entomological Society of America contains a Forum article by three Cornellians (Catherine & Maurice Tauber and their former student - Gilberto Albuquerque, PhD '95). The article features an extensive review of the widely scattered literature on debris-carrying behavior by green lacewing larvae, as well as an analysis of the habit's evolution in lacewings.

Climate, Physiological Tolerance and Sex-Biased Dispersal Shape Genetic Structure of Neotropical Orchid Bees
Margarita M. Lopez-Uribe, Kelly R. Zamudio, Carolina F. Cardoso and Bryan N. Danforth.
Understanding the impact of past climatic events on the demographic history of extant species is critical for predicting species' responses to future climate change. Palaeoclimatic instability is a major mechanism of lineage diversification in taxa with low dispersal and small geographical ranges in tropical ecosystems. However, the impact of these climatic events remains questionable for the diversification of species with high levels of gene flow and large geographical distributions. In this study, we investigate the impact of Pleistocene climate change on three Neotropical orchid bee species (Eulaema bombiformis, E. meriana andE. cingulata) with transcontinental distributions and different physiological tolerances. We first generated ecological niche models to identify species-specific climatically stable areas during Pleistocene climatic oscillations. Read more here.
