Abstract
Anomala bengalensis
belongs to subfamily Rutelinae in family Scarabaeidae. These are widely
distributed scarab beetles also known as leaf chafers with ecological and
economic importance in agriculture ecosystem. Adult beetles were collected
during monsoon season by using Light traps fitted with halogen bulb and
installed in open agriculture fields. Specimens were identified by using the
standard keys and then get proceeded for ecological, economical and cytogenetic
analysis. Diploid number 20 was revealed and karyotype exhibit metacentric or
submetacentric type of chromosomes. Mean chiasma frequency and terminalisation
coefficient per bivalent has also been calculated to confirm the recombination
frequency and revealed conservation of chromosomal architecture of Anomala
bengalensis with other species of family Scarabaeidae, while variation of
diploid number in specimens of Anomala bengalensis suggested the important
role of centric fusion and centric fission in evolutionary trend of karyotypic
asymmetry.
