A survey study was conducted on pine trees species in Egypt for the first time.
The survey was comprised the insects and non insects species (spp.). The study
was carried out between the two successive years 2009-2011 in Alexandria and
north coast. It was revealed that a total of 39 spp. belonging to 19 families
and 10 orders were identified. Order Hemiptera had the largest number of species
(13 spp.) under four families. Order Mantodea came in the second place represented
by 6 spp. Then in the next place Diptera represented by 5 spp., both Coleoptera
and Hymenoptera each represented by 4 spp. Then, Thysanoptera represented by
3 spp., followed by Lepidoptera and Orthoptera each represented by 2 spp. Lucaspis
pusilla was considered the most dominant insect in most regions of study,
as it appeared with high frequency and high density. The non insect species
was mainly represented by the dominant phytophagous mite Cenopalpus fewstrii
(Acarina: Tenuipalpidae), in addition to the true spider species. The most abundant
natural enemies were: Aphytis sp. and Encarsia sp. as parasites
and Pharoscymnus varius Kirsch, Cydonia vicina Mulsant and Chilocorus
bipustulatus Linn. as predators. Aspidiotus nerii (Bouche) and Chrysomphalus
aonidum (Linn.) were recorded for the first time on pine species as a host.
Whereas, Leucaspis pini (Hartig) and L. pusilla (Low) were recorded
for the first time on pine trees in Alexandria and north coast although they
were recorded in other regions in Egypt.
