Abstract

The susceptibility of female spruce budworm moths to ULV aerial sprays of aminocarb and phosphamidon was dependent on the proportion of the total complement of eggs a female had laid. Females which laid few eggs were not killed by the insecticides whereas spent and almost-spent females were killed. Methods are described for determining the number of eggs a female has laid, the number of eggs she has to lay, and her total fecundity. These methods are used to evaluate the efficacy of ULV aerial sprays against budworm moths.

Résumé

La vulnérabilité des papillons femelles de la Tordeuse des bourgeons de l’Epinette aux arrosages aériens VUF (volume ultrafin) d’aminocarb et de phosphamidon fut proportionnelle à la quantité totale d’oeufs pondus par une femelle. Celles n’ayant pondu que quelques oeufs n’ont pas été tuées par les insecticides alors que celles qui ont pondu tous leurs oeufs ou presque, l’ont été. L’auteur décrit des méthodes déterminant le nombre d’oeufs qu’une femelle a pondus, le nombre d’oeufs qu’elle a à pondre, puis sa fécondité totale. De telles méthodes servent à évaluer l’efficacité des arrosages aériens VUF contre les papillons de la Tordeuse.
