Abstract

Varying degrees of ovarian development were induced in overwintered Dendroctonus pseudotsugae Hopk., put on (1) host logs, (2) bark chips, or (3) moist glass paper. In 96 hours the ovaries of beetles on logs reached maturation, those on bark chips showed only slight growth, and the third group failed to show any development.Farnesyl methyl ether induced significant ovarian development in beetles kept on bark chips or glass paper. It appears that production or release of gonadotrophic hormone is withheld in insects kept outside their natural gallery environment. Sensory input associated with gallery excavation may initiate ovary development by stimulating endocrine activity.

Résumé

Divers degrés de croissance ovarienne chez Dendroctonus pseudotsugae Hopk. sur (1) des bûches de bois, (2) des copeaux d’écorce ou (3) du papier de verre humide, après l’hibernation de l’adulte. Développement complet de l’ovaire dans le premier groupe, faible dans le deuxième et nul dans le troisième, au bout de 96 heures.Stimulation significative par le farnesyle-méthyle-éther de la croissance ovarienne chez les Scolytes gardés sur les copeaux d’écorce ou le papier de verre. Inhibition évidente de la sécrétion ou de l’émission de gonadostimuline chez les insectes évoluant hors de leur milieu naturel. Déclenchement probable de la croissance ovarienne par l’énergie sensorielle associée au creusage des galeries, en tant que stimulus de l’activité endocrinienne.
