Blue pectolite from the Dominican Republic, also known by the trade name Larimar, has recently entered the U.S. market. Large quantities of this attractive ornamental stone have been found i n cavities and veins of altered basalt. Most of the gemologiccil properties are consistent with those previously reported for pectolite; the cause of color in this material is believed to be related to the presence of small amounts of Cu2+. The color appears to be stable to light, but does react to irradiation and to the heat of a jeweler's torch. It is easily separated from similar-appearing materials.
The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is one of the world's most destructive fruit pests. The species originated in sub-Saharan Africa and is not known to be established in the United States. When it has been detected in Florida and California, especially in recent years, each infestation necessitated intensive and massive eradication and detection procedures so that the pest did not become established. This document is EENY-214 (originally published as DPI Entomology Circulars 4, 230 and 273), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Male antennae of Phyllophaga tristis (Fabricius) (Coleoptera: Scarabaeidae: Melolonthinae) were tested using a coupled gas chromatograph-electroantennogram detector (GC-EAD) system for electrophysiological responses to five sex pheromones identified from other Phyllophaga species including L-valine methyl ester, L-isoleucine methyl ester, L-leucine methyl ester, methyl 2(methylthio)benzoate and methyl 2-amino benzoate. Male antennae responded only to methyl 2(methylthio)benzoate. In a 2003 field test near Greensburg, Kansas, cross-vane traps baited with rubber septa containing 1 mg of methyl 2-(methylthio)benzoate captured 466 male P. tristis. Control traps baited with rubber septa loaded with only hexane captured none. Similarly, in a field test in 2010 in Gainesville, Florida, 265 male P. apicata Reinhard were captured in traps baited with 1 mg of methyl 2-(methylthio)benzoate whereas control traps captured only a single male.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
