PUPA MORTALITY OF ORGYIA TRIGOTEPHRAS BOISDUVAL, 1829 (EREBIDAE LYMANTRIINAE) IN TUNISIA.

Orgyia trigotephras (Boisduval) is a polyphagous moth which is bivoltine in Tunisia, with two generations (spring and autumnal). This work, carried out in northeastern and northwestern Tunisia, aimed at studying pupal mortality of this pest on two host species, Quercus coccifera L. and Pistacia lentiscus L. Two types of antagonist factors were assessed: natural mortality (dried pupae) and mortality caused by parasitoids. Three pupal parasitoids species belonging to Hymenoptera order were identified: Brachymeria tibialis (Walker), Pimpla rufipes (Miller) and Monodontomerus minor (Ratzeburg). [ABSTRACT FROM AUTHOR]
