Survey of eriophyid mites on some fruit trees, with re-descriptions of two newly recorded species and a checklist of eriophyid mites in Egypt (Acari: Eriophyoidea)

In a field survey, 16 eriophyoid mite species were collected from eight species of fruit trees, among which two species were found to be new record to Egypt. They were Tegolophus guavae (Boczek, 1960) on Psidium guajava L. (Myrtaceae) which causes rust on leaves, and Aceria ziziphi Mohanasundaram, 1990, vagrant without damage on Ziziphus spina-christi Willd (Rhamnaceae). These species were redescribed and illustrated from local material. A total of 65 eriophyoid mite species in superfamily Eriophyoidea has been recorded in Egypt due to literature. These species belong to three families, seven sub families, seven tribes and 27 genera. A list of these species has been constructed and presented herein.

(PPRI), Agricultural Research Center (ARC) for mite extraction.A microscope with an attached drawing tube was used for examination and drawing the mite species Tegolophus guavae and Aceria ziziphi which were recorded for the first time in Egypt.The oil lens was used to examine the fetherclaw, microtubercles and male and female genitalia.The measurements are given in micrometer (µm) and GPS technique is used to identify located samples.The terminology and morphological characteristics used in this study are based on Lindquist (1996) and Amrine et al. (2003).All specimens were deposited in the Fruit Acarology Department, Plant Protection Research Institute collection, Agricultural Research Center.
More than 28 original scientific papers published on eriophyid mites from Egypt were collected from different libraries in Egyptian Universities and Research Centers.On the other side, the references collected from Egypt were confirmed by the Catalogue of the Eriophyoidea of the world (Version computer of Filemaker Pro 4.0.(De Lillo & Amrine, 2009) personal communication).All eriophyid species recorded in Egypt and their host plants are now up to date.

Checklist of Eriophyid mites
Although the diversity of Egyptian agro-ecosystem, the total number of eriophyid mites in Egypt does not exceed 1.5% of the recorded number in the world.The collected references on the eriophyid mites in Egypt recorded 65 species during the period from 1919 up to date.The collective work on eriophyid mites in Egypt was conducted in 1984 and 47 species have been recorded in this work.These species included all eriophyid mite species which recorded before 1984 except four species, namely: Aceria alfierii Sayed, Aceria arabicae Meyer, Cecidophyes violae (Nalepa) and Oxycenus maxwelli (Keifer).On the other hand, 12 species have been recorded during the period after 1984 up to date.Table (1) includes 65 eriophyoid mite species in super family Eriophyoidea reported from Egypt.These species belong to three families, seven sub families, seven tribes and 27 genera.Eriophyidae is the largest family represented by 24 genera and 63 species.Family Phytoptidae contains two genera and two species.Diptilomiopidae contains one genus and one species.
