Abstract
Studies on some ecological aspects of Milviscutulus mangiferae (Green) and its  associated parasitoid  on Laurus nobilis L. (Lauraceae) trees were carried out atOrman botanical garden, Giza Governorate, during two successive years 2016-2017 and 2017-2018. Results revealed that total alive stages had four main peaks of high activity on Laurus nobilis and it passed throughout three generations per  year. The first  generation with duration 3.5 months during two years. The second generation with duration of 5& 4.5 months for the two years,  respectively. The third generation with duration of  3.5&4months for two successive years, respectively. Coccophagus scutellaris (Dalman)( Hymenoptera : Aphelinidae) was recorded as a parasitoid associated with M.  mangiferae . The high activity of the two years of study recorded on (mid-October, 1st December, 1st June and the highest one was in 1st August) and (mid-October, mid- December, mid-April and mid-July).The total effects of seven abiotic factors; Max., Mean, Min., Temp. °C, RH%, Wind, Dew point(°C), solar radiation, and (biotic factor) parasitism % on the mean numbers of alive stages during the two years were74.18% and 80.55%, respectively.
