QU Biology Professor Published in Science Journal

Quincy University’s professor of biology, 约瑟夫·R. 科埃略,Ph值.D., in collaboration with Charles W. 霍利迪,Ph值.D., of Lafayette College in Easton, 宾西法尼亚 and Jon M. 黑斯廷斯,Ph值.D., of Northern 肯塔基州 University in Highland Heights, 肯塔基州, recently published an article entitled “Intra-and Interspecific Prey Theft in Cicada Killers.” The study examines prey theft in two cicada killer wasp aggregations: the Pacific cicada killer wasp in Ruby, Arizona and the Eastern cicada killer wasp in Easton, 宾西法尼亚.

Using sand-filled trap nests baited with a cicada, the researchers tested the hypothesis that conspecific females might kleptoparasitize by laying an egg on the cicada and closing the nest cell. Kleptoparasitism is a term to describe the act of taking another creature’s prey. 类似的, the researchers have christened the behavior of wasps appropriating cicadas from their fellow wasps as “provisioned nest cell kleptoparasitism.” The study suggests that provisioned nest cell kleptoparasitism may have evolved in cicada killers as an alternative strategy to standard provisioning, given the dual uncertainties of adult body size and prey availability.

The paper was published in The Journal of Insect Science, Volume 19, Issue 1. The fully open access journal publishes papers in all aspects of the biology of insects and other arthropods from the molecular to the ecological and their agricultural and medical impact.

Dr. 约瑟夫·R. Coelho obtained a B.S. in Biology from the University of California at Riverside and a Ph.D. in Environmental, Population and Organismic Biology from the University of Colorado. He came to Quincy University in 2004. His research primarily focuses on the physiological ecology of insects, especially solitary wasps, and also includes studies in cultural entomology, such as insects in music. He teaches all of the field courses, including Ecology, Environmental Science, 昆虫学, Plant Field Biology and Vertebrate Field Biology.
