Abstract:         The relationship between temperature and eating, and the efficiency of food conversion in Locusta migratoria manilensis (Meyen), was investigated using the contrast weighing method. The results show that the accumulated developmental duration was 56.9, 34.0, 21.3, 17.2, 15.0 d and total food consumption of 3rd to 5th instar nymphs was 0.85, 0.88, 0.82, 0.99 and 0.99 g respectively at 18, 21, 24, 27 and 30. The longevity of male adults was 90.3, 62.8, 47.0 and 38.7 d, and total food consumption was 3.62, 4.67, 4.25 and 4.26 g respectively at 21, 24, 27 and 30. The longevity of female adults was 95.8, 63.0, 46.3 and 40.8 d and total food consumption was 6.97, 10.48, 10.41 and 11.90 g respectively at 21, 24, 27 and 30. Approximate digestibility reduced with increasing temperature. The efficiency of conversion of ingested food increased in nymphs from the 3rd to 5th instar. While the approximate digestibility was significantly different (P<0.05) at 18 and 30, temperature had no effect on the efficiency of conversion of ingested food in adult (P >0.05).
