Christian Nansen: Radiometric Energy Indicates When Beetles Are 'Terminally Ill'
But non-healthy insects, just like sick humans, can also show changes in body reflectance.
Newly published research led by a University of California, Davis agricultural entomologist shows that radiometric energy reflected by pesticide-exposed adult beetles indicates when they become “terminally ill.”
Christian Nansen, lead author of “Detection of Temporal Changes in Insect Body Reflectance in Responses to Killing Agents,” published in PLOS ONE, said the first-of-its-kind research is “completely non-destructive and completely non-invasive.” “The results may be of considerable relevance to insect physiologists and toxicologists studying responses to treatments and/or to behavioral entomologists studying adaptations and behavioral responses,” he said. -more-
Our Championship Linnaean Team and How They Did It
Those were two of the questions asked of the three-member team from the Department of Entomology and Nematology, University of California, Davis, when they competed in the Linnaean Games at the Pacific Branch of the Entomological Society of America's recent meeting in Coeur d'Alene, Idaho.
They not only answered those questions correctly but went on to win the branch championship. The UC Davis team--comprised of captain Ralph Washington, Jr., and members Jéssica Gillung, and Brendon Boudinot-- will now compete in November at the national Linnaean Games hosted by the Entomological Society of America (ESA) in Minneapolis. -more-
UC Davis Bees 'Buzz' in National GeographicMay edition of National Geographic.
Staff research associate/beekeeper Billy Synk worked with and assisted photographer Anand Varma's needs for a year in the development of the illustrated article. Extension apiculturist emeritus Eric Mussen, who retired last June after 38 years of service, served as a research fact-checker, contacted by National Geographic. The article, authored by Charles Mann asked “Can the world's most important pollinators be saved?' and pondered “how scientists and breeders are trying to create a hardier honeybee.” -more-

'Astonishing Ant Man' Jack Longino to Present Seminar May 27John "Jack" Longino, professor and associate chair of biology at the University of Utah, Salt Lake City, and the adjunct curator of entomology, Utah Museum of Natural History, University of Utah, will speak on "Project ADMAC or Ant Diversity of the Mesoamerican Corridor" from 12:10 to 1 p.m. in 122 Briggs Hall.
Ant specialist Phil Ward, professor of entomology, UC Davis Department of Entomology and Nematology, will introduce and host him.
"The MesoAmerican corridor is a zone of complex tectonic history, episodic biotic interchange between large continents, and frequent mountain-building," Longino said. "Ants blanket this landscape, forming a tapestry of fine-scale habitat specialization and geographic replacement." -more-
