Abstract

Spodoptera litura is a polyphagous pest that destroy the agricultural and horticultural crops, especially maize, okra, cabbage, and cotton in the globe. There are different host pantons that Spodoptera litura feed. The current study was conducted to check the host preference of pest on different hosts. The study resulted in the feeding preference of Spodoptera litura in cabbage followed by okra and alfalfa. The growth and development of pest was significantly shorter on cabbage and could complete properly on cabbage leaves than other tested hosts (okra and alfalfa). The mean developmental period of 1st, 2nd, 3rd, 4th, 5th, and 6th larval instar on cabbage was 3.30, 3.40, 3.61, 4.33, 6.44, and 5.29 days, respectively, while 4.00, 3.59, 4.69, 4.43, 6.99, and 6.68 days on alfalfa, respectively. The total developmental period of 1st-6th larval instar on cabbage, alfalfa and okra was 26.19, 33.74 and 29.38 days, respectively. The survival rate, fecundity, fertility and longevity of Spodoptera litura were higher in cabbage. Therefore, cabbage was recorded as the most suitable and preferable host for its population growth.
