Species Composition and Relative Abundance of Some Insects on Citrus Plants in Lel Pyin Village, Thazi Township Pont Pont Han Tin Abstract The present study was conducted to investigate the occurrence of some insects on some citrus plants in Lel Pyin Village situated east of Thazi. A total of 34 species of insects belonging to 33 genera, 21 families and seven orders were recorded during December 2018 to July 2019. The specimens were collected twice per month. The species composition was (44.12%) in the order Coleoptera, (26.47%) in Hemiptera, (8.82%) each in Diptera and Hymenoptera, (5.88%) in Blattodea and (2.94%) each in Orthoptera and Lepidoptera.

During the eight month study, the highest numbers of individuals were observed in March and the lowest in December. Among the 34 species recorded, the highest number of 30 species was revealed in June, the lowest number of 10 species in January and February. Papilio demoleus and Lasius niger were recorded as very common (vC), 15 species were recorded as common (C), 17 species were recorded as uncommon (uC) throughout the study period.
