English : Activity of Peach Twig Borer Anarsia lineatella Zeller and its associated Bio Agents on Peach trees
Arabic : نشاط ثاقبة براعم الخوخ Anarsia lineatella والأعداء الحيوية المصاحبة لها على أشجار الخوخ
Abstract The seasonal activity of the peach twig borer, Anarsia lineatella Zeller was investigated during 2004 and 2005 seasons. The data revealed that the infested twigs empty from larvae (15%) were higher than that with larvae (1.25%) in February. The situation was reverse in April which recorded 8% and 14.75% for both, respectively. In fruits, infestation began to appear in the third week of March which recorded 2% whereas the maximum rate was recorded in May (16.75%) Three species of hymenopterous parasitoids were found, they were; Apanteles ruficrus Haliday (Fam. Braconidae), Diplazon laetatorus Fab. (Fam. Ichneumonidae) and Microgaster tiro Reinhard (Fam. Braconidae). These parasitoids reached its maximum during April (13.5%) which seems to be more active which were positively correlated with the rate of infestation (r = + 0.799). In spite of presence of four predatory species (Coccinella undecimpunctata L, Rodalia cardinalis Mulsant, and Scymnus syriacus Marseul (Coleoptera: Coccinellidae) and Syrphus sp. (Diptera: Syrphidae)), but it seems to be less active which recorded very slight positive correlation with the rate of infestation (r =+0.423)
