Insect Fauna, Diversity, Population, Karachi Central District.


Present study was aimed at collection, identification and comparison of species richness, abundance and evenness of insect fauna from various localities of central district of Karachi city during January to December 2019. A total number of 43 species and subspecies belonging to 34 families and representing 10 orders were recorded. Among which Sarcophaga, Musca, Culex, Xylocopa, Apis, Cimex, were found to be most prevalent whereas Necrobia, Acrida, Anacridium, Tabanus, were found least in number during study period. Due to insect pollinators’ relatively small functional requirements, habitat range, life cycle, and nesting behavior relative to larger mammals, we argue that pollinators put high priority and high impact urban conservation within reach. The present insect data base will be helpful in designing future integrated pest management studies.
