The effectiveness of 28S and 16S molecular regions in resolving phylogeny of Malaysian microgastrinae (Hymenoptera: Braconidae)

摘要

The phylogenetic relationships of Microgastrinae remains unclear though some studies have been conducted to resolve it. The function of Microgastrinae as endoparasitoids of Lepidopteran larvae makes this subfamily an ideal and potential species to be applied as biological control agent of infesting crops. In this study, a total of 13 microgastrine samples under 13 genera were collected from nine localities throughout Peninsular Malaysia. Two molecular regions, 28S nuclear marker and 16S mitochondrial marker were utilized in this study to examine the effectiveness of those regions in resolving the relationships within Microgastrinae. Total of 36 sequences were implemented in the analyses of NJ, MP and Bayesian for both markers. Results obtained from this study were supported by morphological and biological characters. Henceforth, the outcome from this study provides a proof of effectiveness of 28S and 16S molecular markers in studying the phylogenetic relationships of Microgastrinae from Malaysia exclusively and Oriental generally.
