Abstract

The parasitic wasp,Edovum puttleri Grissell, was successfully reared onLeptinotarsa decemlineata (Say) in the laboratory and increased in sufficient numbers for inoculative release studies in the spring and summer. The effects of temperature on parasite development, and host-parasite ratios in the laboratory are presented. The sex ratio of parasites reared in the laboratory are compared to those released and recovered in the field.

Résumé

L'Hyménoptère parasite,Edovum puttleri, a été élevé avec succès au laboratoire sur doryphore et s'est suffisament multiplié pour permettre des lâchers inoculatifs au printemps et en été. Un rapport parasite/hôte de 1 pour 3 œufs dans les programmes d'élevage au laboratoire aboutit à un sex-ratio de 2 femelles pour 1 mâle dans les échantillons examinés au laboratoire et en plein champ.
