Abstract
The exotic root weevil egg parasite,Tetrastichus haitiensis Gahan, imported from Puerto Rico and released in Florida between 1969 and 1971, was found established on citrus root weevil egg masses in 1978 near Oakhill, Florida. It was also recovered there from field-collected weevil egg masses from June to August 1978 and from citrus bouquets containing egg masses placed in the grove during July and August 1978. In addition, a new species ofTrichogramma was discovered. In the laboratory, this species parasitized egg masses of 4 species of weevils that attack citrus in Florida. These areDiaprepes abbreviatus (L.),Pachnaeus litus (Germar),P. opalus (Olivier) andArtipus floridanus Horn.
Résumé
On a observé en 1978 l'établissement dans les pontes du charançon des racines de citrus du parasite exotique du charançon des racines,Tetrastichus haitiensis Gahan, lâché en Floride entre 1969 et 1971. Ce parasite a été signalé dans des pontes du charançon récoltées dans les champs de juin à août 1978 et dans des bouquets de citrus renfermant des pontes placées dans les vergers en juillet et août 1978. Une nouvelle espèce deTrichogramma a été découverte. En laboratoire ce trichogramme parasite les pontes de 4 espèces de charançons nuisibles aux Citrus en Floride:Diaprepes abbreviatus (L.),Pachnaeus latus (Germar)P. opalus (Olivier) etArtipus floridanus Horm.
