Abstract : We have been the work of field and laboratory study on the most important insect pests on the main fruits of juniper (Juniperus procera Hoschst) during the period from February to October. This study has focused on the work of field and laboratory surveys in four different geographic locations Abha province included a rosette protected and cherished and loan and Anumeis. Where different techniques were used to identify the most important pests and their growth curves with a hook density of the most densely complex natural enemies of insect predators and parasites and true spiders. Add to that identified the incidence of lesions during the period of fruit maturation of these fruits with the ratio of incidence to 61% in the study site Protectorate rosette. It turns out that the most important pests that cause heavy casualties on the fruits of juniper included injected two major first track to the rank of squamous wings (order: Lepidoptera) a worm fruits of juniper Strepsicrates cryptosema which follow the family of worms, seeds and fruits (Tortricidae) The scourge of other major it bugs the fruits of juniper Taylorilygus sp . And follow the rank of half wings (order: Hemiptera) and the family of plant bugs (Miridae). It emerged from this study also bug nymphs, eggs and fruits of juniper attacking the first two types of parasites parasites parasites on eggs Egg parasitoids and tracking of sex in the family Scelionidae Telenomus The nymphs Vtm Note parasites exit tracking sex Megastigmus Torymidae in the family and the fruits of juniper worm larvae attack the parasites follow the family Ichneumonidae. It was evident from the nursery laboratory to determine the percentage of parasitism that parasite eggs bugs fruits of juniper accounted intrusion in the amount of 17.41%, while the parasites nymphs bugs fruits of juniper and formed the proportion of parasitism of nymphs and of 69.92%, while the parasite larvae fruits of juniper and formed the proportion of parasitism and of 12.67%, especially during periods of activity of these lesions. Add to that have been identified complex the most important natural enemies of predator insects, spiders, true, but remain parasite insect is a biological filters Bioagent that we recommend focusing on the work of biological studies include the number of atomic and Education Laboratory, and all organized within the natural ecosystems of forests of juniper to determine their effectiveness in reducing and curbing the fruits of juniper communities lesions Home. The other hand, this study will continue until the completion of a full year.
