Biological control of the beanfly,Ophiomyia phaseoli [Dipt.: Agromyzidae], byOpius spp. [Hym.: Braconidae] in the Hawaiian Islands

Abstract

Attention is drawn to the transfer of the beanfliesMelanagromyza phaseoli (Tryon) andM. spencerellaGreathead to the genusOphiomyiaBraschnikov bySpencer (1973). The confusion over the nomenclature of theOpius spp. parasites is discussed and it is shown that the namesO. phaseoliFischer andO. importatusFischer should be used. Their introduction into Hawaii and establishment is briefly discussed in relation to their effectiveness as biological control agents. It is shown that they show a high degree of consistency of parasitism which has resulted in an acceptable degree of control ofOphiomyia phaseoli although there is no evidence that they act in a density dependent manner.

Résumé

On attire l'attention sur le transfert parSpencer (1973) des mouches du haricot,Melanagromyza phaseoli (Tryon) etM. spencerellaGreathead dans le genreOphiomyiaBraschnikov. La confusion dans la nomenclature desOpius parasites est discutée et il est indiqué que les dénominationsO. phaseoliFischer etO. importatusFischer sont à utiliser. L'introduction de ces parasites et leur acclimatation aux Iles Hawaï est brièvement discutée par rapport à leur efficacité comme agents de lutte biologique. Ils ont permis d'obtenir un contrôle suffisant deOphiomyia phaseoli bien qu'il n'y ait pas de preuves qu'ils interviennent d'une manière dépendant de la densité de l'hôte.
