Abstract

An experiment was conducted to determine the aphid pests’ diversity in Jahangirnagar University Campus from January to December, 2015. Total ten aphid pests were identified viz, Acyrthosiphon pisum, Aphis craccivora, Aphis fabae, Aphis gossypii, Aphis nerii, Brevicoryne brassicae, Hyadaphis coriandri, Lipaphis erysimi, Macrosiphum euphorbiae, Myzus persicae.. Exploration of aphid pests showed that they caused serious damage to agricultural crops by attacking different part of plants. Seasonal abundance of aphid pests showed that they had close relation with meteorological factor. From the last of September, aphid populations were found to decrease gradually mainly due to rain and appearance of many natural enemies in the crop. Along with diversity study, phylogenetic relationship of aphid pests was constructed based on mitochondrial COI gene. In sequence alignment, out of ten aphids Acyrthosiphon pisum showed non conserve region than rest. Analysis of interspecific genetic divergence exposed the genetic range of aphid pests was 0.05-0.11. For confirmation of origin and evolution of aphid pests, phylogenetic tree and haplotype analysis was performed. Both Neighbor-Joining and Maximum likelihood methods for tree construction and haplotype analysis showed My. persicae was genetically most diverge among all other studied aphids. Perhaps the control program for one aphid species will be applicable for other aphid pests because they originated from common ancestor and they were closely related to each other. This information would be helpful in Integrated Pest Management program for successful control of aphid pests in Bangladesh.
