摘要: Egg parasitoid Trichogramma strain (TNV) received from Kharga Oasis, New Valley Governorate, Egypt, is used in controlling certain date palm lepidopteran insect pests. The morphological features of adult wasps and genetically identification the was carried out. Scanning electron microscopy (SEM) light microscope were for studying morphology male female adults measurements. Data revealed that body length shorter than female. However, TNV longer species, evanescens West. studied by several authors. In addition, external antennae, wings, genitalia differed TNV Trichogramma. based on molecular genetic techniques using PCR amplification sequencing internal transcribed spacer two (ITS2) region rDNA. BLAST result phylogenetic analysis ITS2 rDNA sequence closely related to turkestanica. Obtained results confirmed sp., as a biological control Valley, T. turkestanica not evanescens.
