Abstract
Citrus trees in Egypt infested with different insects and mites. The scale insects, leaf miner, fruit flies and phytophagous mites are the most important citrus pests. The present work dealt with incidence of these pests, on four citrus varieties (Balady Mandarin, Valencia, Navel and Balady orange), and their associated insect and mite predators. The study indicated that there are seven species of insect pests and two of predators as well as four species of phytophagous mites and two species of predacious mites. Also, the current study showed that parlatoria black scale, Parlatoria ziziphi (Lucas) was most common inhabiting the four tested varieties, as, it was preferred to infect the mandarin trees followed by Navel orange, Valencia and Balady orange, respectively. The four species of phytophagous mites which the study dealt with them were, Panonychus citrii, Phyllocoptruta olievora, Eutetranychus orientalis and Brevipalpus californicus. Navel orange was be more infestation with Phyllocoptruta olievera than the other varieties of citrus, while the highest number of Panonychus citrii and Brevipalpus californicus recorded on mandarin (85.63 , 45.3) as a sum of averages, respectively. The results obtained showed a fluctuation in the med-fly and peach fly during study season. On the other hand, the study proved the effectiveness of some pesticides in the control of insect and mite pests, where the percentage reduction of each has been reached 100% after 30 days post application.
