Abstract
Pteroptrix smithi (Compere) is a gregarious internal parasite of the diaspine scaleChrysomphalus aonidum. During the last few years, both host and parasite were mass reared in the laboratory on squash fruits. Releases were made in scaleinfested citrus orchards that were not reached by the parasite’s natural spread. Parasites were recovered from many of the release sites.
Résumé
Pteroptrix smithi (Compere) est un parasite interne de la cochenilleChrysomphalus aonidum. Ces dernières années, les hôtes ainsi que les parasites ont été élevés en masse en laboratoire sur des fruits de citronelle. Ces parasites furent libérés dans des vergers d’agrumes infestés de cochenilles qui n’étaient pas atteints par l’expansion naturelle de l’Aphelinide. Des parasites ont été repris de plusieurs sites de lâchers.
