Abstract

A Latin square design field experiment using treatment, site, and occasion as main effects was set up in spring 1981 to assess the responses of Trypodendron lineatum (Olivier) and Gnathotrichus sulcatus (LeConte) to traps baited with the pheromones lineatin and sulcatol alone and in combination with each other and with ethanol plus α-pinene. Addition of sulcatol to either lineatin or lineatin plus ethanol plus α-pinene resulted in significantly reduced catches of T. lineatum. Addition of ethanol plus α-pinene to sulcatol or lineatin resulted in significantly greater catches of both sexes of G. sulcatus and T. lineatum. These results suggest that separate traps be set out for each species in mass trapping suppression programs in timber processing areas and that ethanol and α-pinene be included with the pheromone to maximize catches of both of these ambrosia beetle species.

Résumé

Un plan expérimental de type carré latin, dont les facteurs principaux étaient le traitement, le site et l'occasion, a été mis à l'essai au printemps de 1981 afin d'évaluer les réponses du Trypodendron linéatum (Olivier) et du Gnathotrichus sulcatus (LeConte) à des pièges appâtés avec les phéromones linéatine et sulcatol, seules et en combinaison l'une avec l'autre ou avec l'éthanol plus l'α-pinène. L'addition de sulcatol soit à la linéatine, ou à la linéatine avec l'éthanol plus l'α-pinène, a causé une réduction significative des captures du T. lineatum. L'addition de l'éthanol plus l'α-pinène au sulcatol ou à la linéatine, a augmenté significativement les captures des 2 sexes des G. sulcatus et T. lineatum. Ces résultats indiquent que des pièges séparés devraient être installés pour ces 2 espèces lors des campagnes de suppression en masse dans les régions entourant les sites de conversion du bois, et que l'éthanol et l'α-pinène devraient être ajoutés à la phéromone afin de maximiser les captures de ces 2 espèces de scolytes du bois.
