Thripid species were represented by seven species in olive groves at Ismailia governorate during 2013 and 2014 on different cultivars (El-Egazy; Manzanillo and Pequal) and weeds in olive groves. The species are Frankliniella occidentalis (Pergaade); Thrips microchatus Karny; Scirtothrips aurantii Faure; Haplothrips cahirensis Karny; Dendrothrips eremicola Priesener; Thrips tabaci Lindeman and Sericothrips kassimanus Priesener. First three species are represented in olive trees as a new host. The second three were represented in olive trees before. The last species was recorded on Cynanchum acutum presented under and between olive trees. The Egyptian species are described and figured. Also, synonyms and geographical distribution are given.

A little attention has been given on molecular identification of thrips (Insecta: Thysanoptera) in Egypt. Thus, the primers ITS4A, 28S rRNA, 18S rRNA and the primer pairs COI-1 + COI-2 + COI-3 were used to identify the three dominant thrips species (Haplothrips cahirensis karny; Dendrothrips eremicola Priesener and Hydatothrips kassimanus Priesener). The samples were collected from a private olive grove during 2013 and 2014 at Ismailia governorate, Egypt. DNA sequence data for 28S rRNA gene showed a positive response to H. cahirensis and D. eremicola only, while 18S rRNA reacted with all species. ITS4A and COI-1 + COI-2 + COI-3 showed a negative response to the studied species. DNA sequences of the species based on 18S rRNA were recorded in the Gene Bank. The phylogenetic tree of the three thrips species was given also.
