Abstract
A survey of coleopterous insects was conducted at Alexandria Governorate (Burg Al-Arab and Al-Amria districts) and Qena Governorate (Quos and Deshna districts) during two successive years from April 2018 till March 2020 using Robinson light traps set up at Alexandria in Burg Al-Arab (Al-Garbaniat and Burg Al-Arab regions) and in Al-Amria (Abo Doma, Rahim & Gurisat and Sidi Masoud regions) and at Qena in Quos and Deshna).
In Alexandria, this survey revealed the collection of (10539 and 11024 individuals) and (96130 and 10821 individuals) in Burg Al-Arab and Al-Gharbaniat regions; (Burg Al-Arab district) throughout the first and second years, while numbers of the whole catches in Al-Amria district were (35715 & 37397 individuals), (5615 & 5582 individuals) and (4721 & 5481 individuals) in Rahim and Gurisat, Sidi Masoud and Abo Doma regions, respectively in the two studied years (2018-2019 and 2019-2020).
The collected individuals in Alexandria, were separated, listed, and identified under their related families, genera, and species (25 families and 76 species). Data also show that, the species of family Staphylinidae dominated the coleopterous catches in all regions of both districts followed by Carabidae, Anthicidae and Tenbrionidae. Other families were less abundant and represented by smaller numbers of individuals. On the other hand, Nitidulidae, Phalacridae, Apionidae, Monotomidae and Mycetophagidae were represented by rare numbers in the regions under study.
In addition, family Coccinellidae was represented by two species: Rodalia cardinalis Muls. and psyllobora renifer Casey which was collected and identified for the first time in the Egyptian fauna. Also, family Ptinidae, included Dignomus irroratus Kiesen was collected and identified for the first time in Egyptian fauna.
In Qena, the number of coleopterous specimens of the whole catches were 47946 & 49146 indivduals in Deshna and 34528 & 34945 indivduals in Qous in the two years, respectively.
In Qena, it was observed that the species of family Scarabaeidae dominated the other coleopterous catches followed by Carabidae, Staphylinidae and Bostrychidae in Deshna district; other families were less abundant and less represented. In Qous district, family Carabidae dominated the coleopterous catches followed by Tenebrionidae, Scarabaeidae, Staphylinidae, Bostrychidae, Dytiscidae and Elateridae.
The population dynamics of the three predators dominated other natural enemies in Alexandria and Qena Governorates was conducted. These predators were Paederus alfierii Koch, Philonthus quisquiliarius Gyllenhal and Cercyon laminatus Sharp. Data indiated that P. alfierii was highly abundant in Al-Amria district followed by Borg Al-Arab and Quos districts and was totally absent in Deshna district in both seasons. Ph. quisquiliarius was highly abundant in Upper Egypt (Qous and Deshna districts) than in Lower Egypt (Al-Amria and Borg Al-Arab districts). C. laminatus was more abundant in Lower Egypt (Al-Amria and Borg Al-Arab districts) than in Upper Egypt (Qous and Deshna districts).
