“…This parasitoid had two peaks of abundance for the parasitoid during July and November on A. aurantia (Moustafa, 2012), two peaks on H. lataniae (Bayoumy, 2010), one peak on H. lataniae in mid-June and four on Aonidiella orientalis (Mohammad et al, 2002) andC. dictyospermi in Morocco (Benassy andEuverte, 1973). The numbers of scales parasitized by H. aspidioti ranged between 7.5 and 63 individuals of P. ziziphi.…”

The diaspidid black scale, Parlatoria ziziphi (Lucas) is amongst the most destructive pests to citrus in several countries. This study was conducted in navel orange orchard at the experimental farm belonging to Mansoura University during 2017/2018 and 2018/2019. Parlatoria ziziphi had three peaks of abundance annually. The highest peaks occurred in autumn. The ectoparasitoid, Aphytis sp. had four peaks of abundance annually and its populations were synchronized with those of the insect. The endoparasitoid, H. aspidioti exhibited three-four peaks of abundance annually and the parasitoid populations were coincided partially with those of the insect. However, as the population of insect increased, the parasitism rates by Aphytis was significantly decreased, whereas those of H. aspidioti were unstable. Thus, Aphytis seems to be inverse-density mortality agent and its releases must be early in the season on low pest populations. Parasitism% by Aphytis sp. had two peaks annually, almost occurred in the period from May to August. Aphytis parasitism percentages ranged from 14.6 to 35.4%, whereas those of H. aspidioti ranged from 5.7 to 16.5% in both years. Harbolepis aspidioti recorded three peaks of parasitism in January, May, and August annually with the highest one was in January. Predation% in P. ziziphi populations ranged from 5.8 to 18.9%. The highest percentages of unknow mortality (12.3-17.8%) were in the period from December to January annually. The total population mortality ranged from 37.9 to 73.9%. Both parasitoid species contributed with the highest fate in the total population mortality of P. ziziphi in all seasons.

In citrus groves, beneficial insects that reduce abundance of pests are considered a key component of integrated pest management strategies. The aim of this article was to assess the biodiversity of parasitoids and predators in citrus orchards in Moroccoto facilitate future investigations on their potential as biocontrol agents. Data of 105 citrus beneficial insects were gathered and summarized in a data matrix. Variables such nature, target pests, type, establishment, and efficacy were assessed. More than two-thirds of parasitoids and predators species identified in citrus groves of Morocco (105 species) are native (> 70%). Both groups represent only a small fraction of the introduced species. The mostly attack armored scale insects (Diaspididae) and aphids (Aphididae). The ladybeetle Rodolia cardinalis (Mulsant) (Coleoptera: Coccinellidae) is the first beneficial species introduced in 1921 to the Moroccan citrus orchards to control the cottony cushion scale Icerya purchasi (Maskell) (Hemiptera: Monophlebidae). Major introductions of these parasitoids and predators were carried out during the ninetieth to control the main citrus pests whereas they were accidentally introduced. These purposely introduced species are mainly Aphelinidae, Encyrtidae, Eulophidae, Coccinellidae, and Phytoseiidae. Whereas a high proportion of the introduced beneficial insects was established and no species have been reported to be harmful to this date. Considering only the introduced species used in classical biological control context, about 20 and 40% of them are considered as effective or partially effective, respectively.
