Abstract

A mathematical model is developed which simulates the effect of the number of eggs in females, food source, and soil conditions, on ovogenesis and oviposition of Japanese beetle populations. The number of eggs in females is used as the state indicator, and simulated trends are compared to field data. Potential applications in pest management are discussed.

Résumé

Un modèle mathématique est décrit, simulant l’effet du nombre d’oeufs matures contenus dans les voies génitales des femelles, de la source de nourriture, et de conditions édaphiques, sur l’ovogènese et l’oviposition d’une population de scarabées japonais. La variable indicatrice utilisée pour fins de comparaisons avec des populations naturelles est le nombre d’oeufs dans les femelles. Certaines applications en amenagement sont mentionnées.
