Abstract

Biological control of eggplant pests in general, and (CPB)Leptinotarsa decemlineata (Say) in particular, is highly problematic.Edovum puttleri Grissell, an exotic egg parasitoid which has been found potentially effective, is being reared to this end. Frozen CPB eggs (−18°C) proved to be accepted and suitable for parasitization byE. puttleri. However, when given a choice between 20 frozen and 20 normal eggs every 2 days, the females exhibited a significant preference for the latter. Parasitization and host predation patterns related to female age are described by 2 opposing fourth-order polynomial functions. Parasitization increased up to day 10, followed by progressive decline. Average life span per female was 31.10±.58, with a recorded maximum of 56 days. High predatory behaviour of older females, which showed a decrease in parasitization, was observed in these experimental conditions.

Résumé

Le «contrôle biologique» des phytophages de l'aubergine sous serre, celui deLeptinotarsa decemlineata Say notamment, est particulièrement difficile. Le parasitoïde exotiqueEdovum puttleri Grissell s'est montré potentiellement efficace et son élevage est pratiqué à ce titre dans les laboratoires de quelques Instituts, dont le nôtre. On a démontré que les œufs congelés de l'hôte (−18°C) étaient propres au parasitisme parE. puttleri. Cependant, si les femelles ont le choix tous les 2 jours, entre 20 œufs congelés et 20 œufs normaux, elles préfèrent ces derniers. Les exemples de parasitisme et de prédation liés à l'âge de la femelle sont représentés par 2 fonctions polynomiales opposées du 4e degré.

La durée moyenne de vie par femelle était de 31,10'±3,58 avec une vie maximale de 56 jours. Dans les conditions expérimentales, on a remarqué une forte propension à la prédation des femelles plus âgées qui manifestent par contre une diminution au parasitisme.
