Abstract
Ladybird beetles (coleoptera: coccinellidae) were collected from the fields of wheat, barley, alfalfa, beans, mustard, vegetable crops, and ornamental plants from experiment station in the Faculty of agriculture, Cairo university Giza, during two years 2013-2014. Six species (coccinella undecimpunctata, exochomus nigripennis, hyperaspis marmottani, rodolia cardinalis, scymuns syriacus, and Hippodamia variegata) belong to six genera, from five tribes and three subfamilies; were recorded throughout the study and were morphologically identified and a taxonomic key was also given. Using molecular tools based on 28Sr DNA, this study aimed to show the relationship among five species: Coccinella undecimpunctata, C. septempunctata, cydonia vicina isis, C. v. nilotica, and Hippodamia variegata, collected from Giza region throughout the years 2013 and 2014. Results revealed that the species C. undecimpunctata, C. septempunctata and H. variegata were identical to the same specimen species in the gene Bank. Meanwhile, a monophyletic relationship appeared between the species C. v. isis and C. v. nilotica compared to the species cheilomenes sexmaculata. The sequences obtained in this study were deposited in the gene Bank. Analysis of phylogenetic relationships tree database was performed using UPGAMA method by MEGAV6. software
