Abstract

Field studies were conducted with the synthetic pheromone of peach twig borer to determine the effect of trap distance from host plant, pheromone concentration on number of captured males and seasonal flight patterns in plum and apricot orchards. Traps placed in pomegranate plantation and in fallow land caught significantly fewer males than those placed at the centre and border of plum orchard. However, significantly more moths were caught in traps placed in pomegranate orchard than those in fallow ground. Males captured increased as the concentration of synthetic pheromone increased from 2 to 6 mg per septa. Thereafter, males captured decreased as the concentration increased.

Résumé

Ces études ont été conduites dans le champ avec les pheromone synthétique sur le ver à pêche pour detérminer l'effect dupiège distance de la plant hâte, la concentration de pheromone par numbre des maies capturés, et l'activité devol saisonal dans les vergers de prune et l'abricot. Les résultats obtenus ont montrés que les numbres des maies capturés avec les pièges placées dans les champ de grenadier et en tèrre jachère moin de celles placés dans le centre et la bordure dela prune verger. Cependant, les mites attrapées par les pièges placées dans la plantation de grenadier ont été significantivement plus que cells capturées par les pièges placée sur la tèrre jachère. Maies capturés augment avec L'augumentation de la concentration de pheromone synthétique de 2 à 6mg/septum par la suite, capture des males diminues par l'augmentation de la concentration.
