چکیده

olive leaf moth, palpita :union:alis (hübner) is an injurious pest of nurseries, of young olivetrees, and also of the suckers of old trees. in feeds on some other such host plants as ash,jasmine and privet. knowledge of the biology and life table parameters of the pest species isneeded in any pest management program. in this work, life history traits and life tableparameters as well as the population projection of p. :union:alis were studied at 25± 1oc, 65±5% r.h. and photoperiodism of 16:8 (l: d) on three olive cultivars of: zard, rowghani andkronaiki. the age- stage, two-sex life table is made used of incorporate both sexes and thevariation in developmental rate among individuals and as well to obtain accurate populationparameters. the developmental time of immature stages (egg to adult emergence) on kronaiki,rowghani and zard recorded were 35.05, 33.78 and 36.08 days, respectively. the longevity ofthe female vs male adults in the three varieties were (9.33 and 7.00), (10.64 and 10.60) and(10.21 and 8.10) days, respectively. there was no significant difference observed among thelife table parameters of the three tested varieties. the intrinsic rates of population increase onkronaiki, rowghani and zard were 0.044, 0.049 and 0.047 d-1, respectively. the highest netreproductivity was found to be 8.61 offsprings per individual on rowghani. mean generationtimes (t) on the three varieties were 43.56, 42.12 and 42.04, respectively. overall, kronaikiwas evaluated as the most undesirable as regards the pest. therefore, considering otheradvantages of the variety and also considering the other pest species, this variety could berecommended as the most suitable one to largely reduce the pest problem.
