Polytene Chromosome Analysis of Bactrocera carambolae (Diptera: Tephritidae)

The present investigation constitutes a first effort to study the polytene chromosomes of Bactrocera carambolae Drew and Hancock (Diptera: Tephritidae). It is a serious pest of the Bactrocera dorsalis complex group, infesting various types of fruits and vegetables in Southeast Asia, Australia and the Pacific. The aim of this study was to determine and analyse each arm of the salivary gland polytene chromosomes of this species individually. The tips, distinguishing characteristics as well as significant landmarks are recognized in each chromosome arm. Photographic illustrations of the chromosomes is presented and discussed. The information can be used for comparative studies among species of the tephritid genera which facilitate the development of novel control methods.
