Often, several parasitoid species may share a common host species. Five species of Ooencyrtus Ashmead (Hymenoptera: Encyrtidae) co-inhabit the egg clusters of Stenozygum coloratum Klug (Hemiptera: Pentatomidae), in the East Mediterranean region. Their relative abundance and spatial and seasonal occurrence were investigated. Parasitism and parasitoid male ratios gradually increased to about 50 and 26.8%, respectively, from May to October. O. telenomicida Vassiliev was dominant in Mediterranean climatic regions and absent from arid areas, O. fecundus Ferrière and Voegelè dominated semi-arid areas, and O. near nigerrimus was the commonest in hot-arid areas. O. near fecundus occurred everywhere but was most abundant in the more extreme weather conditions. O. pityocampae Mercet was uncommon in most areas and absent from arid ones. O. telenomicida abundance was positively, and that of O. fecundus negatively, correlated with annual rainfall. O. near fecundus and O. near nigerrimus abundance was positively correlated with temperature extremes. The results display a clear picture for climatic based spatial niche partitioning, although there is evidence that interspecific competition also plays a significant role in the frequency of occurrence of the studied Ooencyrtus spp. International Organization for Biological Control (IOBC), 2015 Egg parasitism nationallicence Encyrtidae nationallicence Hymenoptera nationallicence Niche partitioning nationallicence Sex ratio nationallicence Variegated caper bug nationallicence Samra Shahar Department of Entomology, The Volcani Center, P.O.
