Tetropium Fuscum

AbstractWe describe the calling posture of the brown spruce longhorn beetle, Tetropium fuscum (F.), and demonstrate, using solid-phase micro-extraction and gas chromatography – mass spectrometry, that this posture is positively correlated with the release of fuscumol, a male-produced long-range pheromone. The posture is observed only in males and is characterized by an extension of the legs that raises the body entirely off the substrate at an angle of approximately 10°, with the posterior end higher than the head. Characterization of the calling posture is a useful diagnostic tool for future research on the reproductive biology of T. fuscum, since a simple visual assessment can be used instead of chemical analysis to determine when males are emitting fuscumol. In addition, we demonstrate that the presence of conspecific males stimulates calling behaviour in T. fuscum. This study contributes much-needed data on the biology and mating behavior of this invasive wood-boring species.

Tetropium Fuscum

The brown spruce longhorn beetle (BSLB), Tetropium fuscum (Fabr.), is native to Europe but has recently been discovered in Halifax, Nova Scotia, where efforts are underway to eradicate it. If attempts to eradicate this beetle are unsuccessful, phytosanitary measures will have to be developed to ensure continued access to markets. We carried out studies to determine the lethal temperatures for different BSLB life stages in spruce. The beetles were exposed to different temperatures for various time periods in lumber of low and high moisture content. Adults died after 30 and 15 minutes exposure to 40 and 45°C, respectively, and pupae died after 30 minutes exposure to 45°C. Larvae required exposure to 50°C for 30 minutes (or 55°C for 15 minutes) to ensure 100% mortality. Larval survival was slightly higher in wood with low moisture content. The study was repeated a second year for the 50°C/30-minute and 55°C/15-minute treatments for larvae and the 45°C/30-minute for pupae at very low moisture (12-15% oven-dry basis) content, with similar results. Our results demonstrate that heat treatment is an effective phytosanitary method to ensure that wood does not contain any live BSLB.Current phytosanitary guidelines listed by the Canadian Food Inspection Agency in its directive "Canadian Heat-treated Wood Products Certification Program (CHTWPCP) for Export" (56ºC, 30 minutes) are more than adequate to ensure BSLB-free wood.

In 1999, red spruce (Picea rubens Sarg.) trees in a small area of the Halifax Regional Municipality in Nova Scotia, Atlantic Canada, were found to be infested and killed by Tetropium fuscum (Fabr.) (Coleoptera: Cerambycidae), a Eurasian species of longhorn beetle. We isolated and identified the fungi associated with T. fuscum in Halifax and compared them with ophiostomatoid fungi associated with Tetropium spp. on spruce in Europe. Ophiostoma species associated with Tetropium cinnamopterum Kirby (indigenous to and transcontinental in Canada) were also compared with those associated with T. fuscum. Strains were identified based on morphological and molecular characters. Ophiostoma piceae (Münch) Syd. & P. Syd., Pesotum fragrans Mathiesen-Käärik, and Ophiostoma tetropii Mathiesen were the most frequently isolated species. Lack of type material for O. tetropii and discrepancies between the ex-type strain of O. tetropii and its original description prompted us to lectotypify this species and designate epitype material for it. The results suggest that O. tetropii was introduced with T. fuscum from Europe into Atlantic Canada.Key words: Ophiostoma tetropii, Tetropium fuscum, molecular phylogeny, invasive species.

The World

Date palm offshoots represent an important source of planting material in many date palm-growing countries around the world. Infestation by the red palm weevil ((RPW) Rhynchophorus ferrugineus), the longhorn beetle ((LHB) Jebusaea hammerschmidti) and the rhinoceros beetle ((OB) Oryctes spp.) hinders commercialization and movement of these offshoots. An effective quarantine protocol, with exposure period of 72 h at 25 °C using ECO2FUME (EF) with phosphine concentration of 1500 ppm has been developed for date palm offshoots against these coleopteran internal tissue borers.
