“…Sphenophorus placidus vestitus has been identifi ed as a major pest of turfgrasses in both its native range and invaded countries, commonly found in golf courses (Hat-sukade, 1997;Yang et al, 2009;León-García et al, 2012) and orchardgrass (Kuhn et al, 2013). The distribution of the species within Cyprus, the presence of established populations and any adverse economic impact on the island are currently unknown, as the presented specimen stands out as the sole individual of S. placidus vestitus detected on the island.…”

Summary The Nearctic weevil Sphenophorus placidus vestitus Chittenden, 1904, an alien pest which is known to infest turfgrasses is reported for the first time on the island of Cyprus. A single specimen was collected from Famagusta (Ammochostos), Protaras in 2012. The species distribution and possible economic impacts are shortly discussed. A checklist for the alien Dryophthorinae of Cyprus is presented.

Volatile and Contact Chemical Cues Associated with Host and Mate Recognition Behavior of Sphenophorus venatus and Sphenophorus parvulus (Coleoptera: Dryophthoridae)

et al. 2018

Beetles in the genus Sphenophorus Schönherr, or billbugs, potentially utilize both volatile and non-volatile behavior-modifying chemical signals. These insects are widely distributed across North America, often occurring in multi-species assemblages in grasses. However, details about their host- and mate-finding behavior are poorly understood. This study tested the hypothesis that volatile organic compounds from host-plants and conspecifics direct the dispersal behavior of hunting billbug S. venatus Say. Further, we characterized the cuticular hydrocarbon profiles of two widespread pest species, S. venatus and bluegrass billbug S. parvulus Gyllenhaal, to assess the potential role of contact pheromones in mate-recognition. In Y-tube olfactometer bioassays, S. venatus males were attracted to a combination of conspecifics and Cynodon dactylon host-plant material, as well as C. dactylon plant material alone. S. venatus females were attracted to a combination of male conspecifics and host-plants but were also attracted to male conspecifics alone. Field evaluation of a putative male-produced aggregation pheromone, 2-methyl-4-octanol, identified from two congeners, S. levis Vaurie and S. incurrens Gyllenhaal, did not support the hypothesis that S. venatus and S. parvulus were also attracted to this compound. Gas chromatography-mass spectrometry analysis of S. venatus and S. parvulus whole-body cuticular extracts indicated a series of hydrocarbons with qualitative and quantitative interspecific variation in addition to intraspecific quantitative variation between males and females. This study provides the first evidence that S. venatus orients toward host- and insect-derived volatile organic compounds and substantiates the presence of species-specific cuticular hydrocarbons that could serve as contact pheromones for sympatric Sphenophorus species.
