Abstract

Food security is challenged by loss of natural habitats that reflect in reduction of insect population which is an alternative source of protein and a pollinator for flowering plants. The aim of this study was to assess the influence of a habitat type in the distribution and abundance of flying insects. Open-field, botanical-garden and water-shed habitats, 100 m apart were identified. Sweep net was standardized by taking 100 sweeps. Collection was done twice a week but two times a day at 0800 h and 1400 h. Sweep net was swung on short vegetation and in air, collected insects were emptied in killing jar containing 70%-chloroform soaked in cotton-wool, covered with aluminum foil. Edible insects were identified by attaching a photo to a questionnaire, administered to students, teaching and non-teaching staff. High proportion of insect was observed in Botanical garden (41%), compared to water shed (35%) and open field (24%). Mosquitoes were dominant in botanical garden (31.1%) and water shed (20.1%), while butterflies were dominant in open field (28.4%). In three habitats, mosquitoes were most abundant (23.8%). Lake-flies (27%) and grasshopper (26.7%) were highly proposed edible species. However, the profession of an individual does not influence the choice of edible insect (P= 0.763). Botanical garden provided insect high enough, showing a great potential as a future habitat that can protect insect species to help fight food insecurity.
