Abstract

Damage caused by the black bean aphid, Aphis fabae Scopoli, on the common bean, Phaseolus vulgaris L., was severest when the aphids were transferred onto bean plants during the preftowering stage. There were significant reductions in the average length of the central shoot, production of flowers, pods and seeds per plant. Seed weight per plant was also significantly reduced when aphid infestation occurred during the preflowering stage. Smaller, but significant reductions to the length of the central shoot, quantity of pods and weight of seeds produced per plant caused by A. fabae were also recorded when the aphids were transferred onto plants at anthesis. When aphid infestation occurred during the grain filling stage the damage caused was minimal and insignificant. The results obtained indicated that the preflowering stage was the vulnerable stage of bean development during which aphid attack is most harmful and, if unchecked, could lead to drastic yield losses.

Résumé

Les dommages causés par l’aphid du haricot noir Aphis fabae Scopoli au haricot ordinaire Phaseolus vulgaris L. étaint plus graves quand les aphids étaient transférés sur les plantes de haricot pendant le stade de la préfloraison. Il y avait des réductions notables sur la longueur moyenne de la pousse centrale, sur la production des fleurs, des cosses et des graines par an.

Le poids par plante était aussi considérablement réduit quand l’infestation de l’aphid a eu lieu pendant le stade de la préfloraison. De plus petites mais importantes réductions sur la longueur de la pousse centrale sur la quantité de cosses, et sur le poids de graines produites par plante, causées par A. fabae avaient ete observées quand le aphids étaient transférés sur les plantes à l’anthesis. Quand l’infectation de l’aphid a eu leiu pendant le stade de classement de graines les dégâts étaient minimes et insiginifiants. Les résultats obtenus ont montré que la période de la floraison était le étape la plus vulnerable dans le développement du haricot; pendant cette période l’attaque de l’aphid est plus nuisible et sans la surveiller, elle pouvait conduire à des pertes massives de vécoltes.
