Abundance and Distribution of the Invasive Ant, Solenopsis invicta (Hymenoptera: Formicidae), in Cypress Savannas of North Carolina
Authors:  Kelly, L.; Sellers, J.
Source: Annals of the Entomological Society of America, Volume 107, Number 6, November 2014, pp. 1072-1080(9)
Abstract:  The ecological effects of invasive ants on ecosystems will depend largely on ant abundance. Cypress savannas of the southeastern United States have high conservation worth, supporting diverse and rare assemblages of species. Distance sampling was used to determine the abundance and distribution of colonies of the invasive ant, Solenopsis invicta Buren, in cypress savannas of two Carolina bays. Colonies were distributed throughout the savannas, save for areas of dense tree or shrub cover. Colony densities were much less ... (Full abstract

Predicting the Geographical Distribution of Two Invasive Termite Species From Occurrence Data
Authors:  Tonini, Francesco; Divino, Fabio; Lasinio, Giovanna Jona; Hochmair, Hartwig H.; Scheffrahn, Rudolf H.
Source: Environmental Entomology, Volume 43, Number 5, October 2014, pp. 1135-1144(10)
Abstract:  Predicting the potential habitat of species under both current and future climate change scenarios is crucial for monitoring invasive species and understanding a species' response to different environmental conditions. Frequently, the only data available on a species is the location of its occurrence (presence-only data). Using occurrence records only, two models were used to predict the geographical distribution of two destructive invasive termite species, Coptotermes gestroi (Wasmann) and Coptotermes formosanus Shiraki...

Water Transport by Coptotermes formosanus (Isoptera: Rhinotermitidae)
Authors:  Gautam, Bal K.; Henderson, Gregg
Source: Environmental Entomology, Volume 43, Number 5, October 2014, pp. 1399-1405(7)
Abstract:  Subterranean termites are extremely vulnerable to desiccation, and high moisture makes their habitat and food favorable for survival and colony growth. Although there is a general perception that termites can manipulate moisture, documentation is surprisingly scanty with regard to how termites transport water and the factors that impact it. There has been no study of water transfer by Coptotermes formosanus Shiraki, a notoriously invasive termite in the southern United States... (Full abstract

Cold Tolerance of the Mediterranean Fruit Fly in Date and Mandarin
Authors:  Gazit, Yoav; Akiva, Ruti; Gavriel, Sagi
Source: Journal of Economic Entomology, Volume 107, Number 5, October 2014, pp. 1745-1750(6)
Abstract:  The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is an endemic pest in Israel and there can be low levels of infestation of dates (Phoenix dactylifera L.). Because C. capitata is considered a quarantine pest by several major importing countries, the export of fresh dates requires the elimination of this pest. For mandarin, cold storage at 1.11°C for 15 d is considered to be an effective treatment for the elimination of C. capitata. In this study, we compared the cold tolerance of C. capitata in ...

Abstract:  Intrinsic toxicities of chlorantraniliprole, fipronil, and imidacloprid were evaluated with topical applications on worker termites. Worker termites were exposed to substrates treated with formulated chlorantraniliprole to study contact toxicity, tunneling, and postexposure behaviors. The intrinsic toxicities (LD50, ng/termite) of chlorantraniliprole (1.25, 0.96, and 0.44) and fipronil (0.12, 0.11, and 0.13) at 11 d were similar for workers from three termite colonies. Imidacloprid toxicity (LD50) values were highly variable among ... (Full abstract

Field and Laboratory Evaluations of Chlorantraniliprole as a Termiticide in Southern Arizona
Authors:  Baker, Paul B.; Miguelena, Javier G.
Source: Journal of Economic Entomology, Volume 107, Number 5, October 2014, pp. 1890-1899(10)
Abstract:  The desert subterranean termite, Heterotermes aureus (Snyder), is the predominant termite of economic importance in the arid southwest. Chlorantraniliprole, a relatively new nonrepellent, slow acting termiticide has been shown to be capable of being transferred among colony members through social interactions, and thus may be effective beyond its original site of application. Using field grids, we evaluated the colony-level effects of chlorantraniliprole on H. aureus foraging activity. Repeated laboratory soil ...  (Full abstract
