Abstract

The effect of planting dates on beanfly infestation was investigated in successively planted bean plants during cropping seasons. The population tended to build up in the course of the season following the initial invasion by egg-laying females. Ophiomyia spencerella (Greathead) and Ophiomyia phaseoli (Tryon) were the species of beanflies infesting the bean plants in all seasons. The number of beanfly leaf punctures, eggs, larvae and puparia were more in late planted than early planted bean crop. The bean crop planted late in the season was severely damaged due to the generally higher population levels which had been building up in the course of the season.

Résumé

L'effet des jours de plantations des haricots sur l'infestation des haricots par Ophiomyia spencerella (Greathead) et O. phaseoli (Tryon) a èté analysé. Les populations des insectes ont tendance à se former pendant la saison de cultures aprés l'invasion initiale par les femelles prêtes à pondre des ouefs. Le nombre des perforations sur les feuilles par les insectes, celui des oeufs, des larves et chrysallides furent tres elevés sur les haricots plantés tard par rapport a ceux plantés très tôt. Les haricots plantes tard ont étè severement endommagé par les populations des insectes qui sont entrain de se former pendant la saison.
