ABSTRACT
Deudorix livia (Klug, 1834) (Lepidoptera: Lycaenidae) is one of the most serious lepidopteran insect pests attacking pomegranate fruit around the world, including Egypt (Assiut Governorate, Upper Egypt). To create an effective program (IPM) to control such harmful pests, accurate identification of the pest morphology and genetic structure is essential. Studies on the morphogenetics of this pest are scarce. So, the goal of this research is to identify it both morphologically and genetically. Pomegranate butterfly immature stages were collected from infested pomegranate fruits and reared in the laboratory until the adult's emergence. By using light and scanning electron microscopy, some morphological structures of males and females were studied. DNA was extracted from the legs of a pomegranate butterfly adult. Also, PCR was conducted by using the mitochondrial CO1 gene for sequencing and phylogenetic tests. The results show that the body scales are a mixture of dark and light gray on the dorsal side and white on the ventral side in both sexes. The average male body length (BL) was 11.674 ± 0.299 mm and was 11.458 ± 1.001 mm for the females. The wing venation is similar in both sexes. For the first time, a partial sequence of the mitochondrial CO1 gene in D. livia was deposited in GenBank (MW463927).
