The consumption and digestion of two Ghanaian eggplant cultivars (Asesewa and Odwanhwoa) and two exotic cultivars (Black Beauty and Florida Market) by larval Selepa docilis were studied in the laboratory. Daily food consumption was highest on Asesewa and lowest on Florida Market. Total food consumption was significantly highest on Asesewa, followed by Odwanhwoa, Black Beauty and Florida Market. The dry weight of food consumed per unit of larval fresh weight per day was highest on Asesewa, followed by Odwanhwoa, Florida Market and Black Beauty. In general, food consumption was higher on the Ghanaian than on the exotic cultivars. The efficiency of food digestion was significantly higher on the Ghanaian than on the exotic cultivars. Growth of S. docilis larvae, recorded by the daily larval fresh weights, was highest on Asesewa, followed by Odwanhwoa, Black Beauty and Florida Market. The conclusion is made that S. docilis is best adapted to Asesewa, then Odwanhwoa, Black Beauty and Florida Market. Furthermore, S. docilis is better adapted to the Ghanaian than to the exotic cultivars.
