Abstract

The southern pine beetle, Dendroctonus frontalis Zimmermann, was studied in the laboratory to determine the influence of associated fungi on its reproduction. First-generation (P) surface-sterilized beetles associated with mycangial fungi (Ceratocystis minor [Hedgecock] Hunt var. barrasii Taylor or SJB 122) constructed more galleries and laid more eggs, at faster rates, than P beetles not associated with these mycangial fungi. No significant differences occurred among non-surface-sterilized P beetles associated with the phoretic blue staining fungus Ceratocystis minor (Hedgecock) Hunt and mycangial fungi or among progeny of P beetles (F1 generation) carrying mycangial fungi. P and F1 surface-sterilized beetles produced more eggs at a greater density than non-surface-sterilized beetles associated with blue stain, but gallery length and the rate of construction were not different. P and F1 surface-sterilized beetles laid more eggs and constructed galleries faster than surface-sterilized beetles that carried no mycangial fungi. The re-emergence rate of beetles was fastest for P beetles associated with C. minor and significantly slower for fungus-free P beetles, P beetles carrying only mycangial fungi, and F1 beetles, respectively. The F1 generation emerged fastest when associated with both mycangial fungi and slowest when associated with SJB 122, and C. minor var. barrasii or no fungus, respectively. This study employed a successful new rearing technique for isolating specific southern pine beetle/fungal associations.

Résumé

Le dendroctone méridional du pin, Dendroctonus frontalis Zimmermann, a été étudié en laboratoire afin de déterminer l’influence de champignons qui lui sont associés sur sa reproduction. Des dendroctones de première génération (P) stérélisés en surface et associés à des champignons mycangiaux (Ceratocystis minor [Hedgecock] Hunt var. barrasii Taylor ou SJB 122) ont construit plus de galleries et ont pondu plus d’oeufs, et à un taux plus élevé, que des dendroctones P non-associés à ces champignons mycangiaux. Il n’y a pas eu de différence significative parmi les dendroctones P non-stérélisés en surface et associés à Ceratocystis minor (Hedgecock) Hunt et au champignons mycangiaux, ou parmi les descendants (génération F1) des dendroctones portant les champignons mycangiaux. Des dendroctones P et F1 stérélisés en surface ont produit plus d’oeufs, à une densité plus élevée, que des dendroctones non-stérélisés associés à C. minor, mais la longueur des galleries et le taux de construction n’étaient pas différents. Des dendroctones P et F1 stérélisés en surface ont produit plus d’oeufs et ont construit des galleries plus rapidement que des dendroctones stérélisés en surface qui ne portaient pas de champignons mycangiaux. Le taux de ré-émergence des dendroctones a été plus élevé pour des individus P associés à C. minor et significativement plus faible pour des individus P dépourvus de champignons, des individus P portant seulement des champignons mycangiaux et des individus F1, respectivement. Le taux d’émergence de la génération F1 a été maximal lorsque les dendroctones étaient associés aux deux champignons mycangiaux et minimal lorsqu’associés à SJB 122 et C. minor var. barrasii ou aucun champignon, respectivement. Cette étude a utilisé, avec succès, une nouvelle méthode d’élevage pour l’isolation d’associations dendroctone/champignon spécifiques.
