Abstract

Asian cavity-nesting honey bee Apis nigrocincta, a native bee species from Sulawesi and the Philippines, plays a vital role in pollinating flowering plants in local ecosystem and agriculture. In this study, we assessed the intraspecific genetic variation of A. nigrocincta using the sequence of cytochrome c oxidase subunit I (COI). Molecular phylogenetic analysis showed that there were three main clades in A. nigrocincta specimens from Sulawesi based on their respective locations (North, Central, and South Sulawesi). Genetic distance analysis using the Kimura 2-parameter (K2P) model showed that the intraspecific genetic distance in Sulawesi specimens ranged from 0.000 to 0.055. There are 26 nucleotide polymorphic sites within Sulawesi A. nigrocincta. The variation was dominated by transition T ↔ C. The molecular identification result was supported by morphological identification. The results of the two methods agree that the specimen under study was A. nigrocincta. The result of genetic distance calculation indicated that although the tested specimens were derived from remote locations, the genetic variation was still within the range of intraspecific variation.

Summary

Introduction

Asian cavity-nesting honey bee Apis nigrocincta, a native bee species from Sulawesi and the Philippines, plays a vital role in pollinating flowering plants in local ecosystem and agriculture. We assessed the intraspecific genetic variation of A. nigrocincta using the sequence of cytochrome c oxidase subunit I (COI). There are nine species of honey bees known to inhabit the world: Apis dorsata, A. laboriosa, A. mellifera, A. florea, A. andreniformis, A. cerana, A. koschevnikovi, A. nigrocincta (Sulawesi, Indonesia, and Mindanao, the Philippines), and A. nuluensis (Kalimantan, Indonesia), with approximately 44 subspecies [4]. Molecular methods have been applied to study intraspecific genetic variation, species identification, and phylogenetic relationship among close-related taxa [6]. We examined the intraspecific variation in A. nigrocincta to facilitate species identification and analyze their genetic distances
