Current Knowledge and Perception of Edible Grasshopper/Locusts’ Consumption in Western Kenya

Abstract

Edible insects play an important role as a protein source of high-nutritional value in the western region of Kenya. However, current knowledge on edible grasshopper/locust species consumed in western Kenya and the perception towards these insects as an alternative protein source are not well documented. A questionnaire was issued to 901 respondents in four counties of western Kenya. The results showed that 91.6% of the respondents had heard that grasshoppers/locusts are edible insects and that 51.2% of the respondents had consumed them. The most frequently identified edible species was Cyrtacanthacris tatarica, with 58.6% cases followed by Schistocerca gregaria (25.7%), while Ruspolia differens was the least identified (1.2%). The majority of the consumers (60.0%) were introduced to entomophagy by their relatives, fewer by their friends (34.0%), and 5.7% by themselves. For those who had never eaten them, 53.8% were unwilling to try, while 11.9% were willing. On availability in the market, 97.9% indicated having never bought, while only 2.1% had bought the insect. The highly preferred method of cooking was smoking/roasting at 53.3%. The majority at 50.1% indicated the willingness to rear, while 21.0% were undecided. The frequency of the respondents who highly preferred to rear the insect for food and feed was 50.4%. The results suggest that the study population has knowledge of edible grasshopper/locust species and is willing to rear edible insects as an alternative protein food source.
