Abstract: Food consumption and utilization of adult Catantops pinguis(Stal) (Orthoptera:Catantopidae) were investigated under different temperatures.The results showed that temperature affected the food consumption remarkably,and food consumption increased with the rise of temperature.The temperature had a negative effect on the approximate digestibility(AD).The temperature affected the growth of this insect as well,but rather complicatedly.The weight of body did not increase with the rise of temperature linearly.The results indicated that food consumption,approximate digestibility and growth of C.pinguis(Stal)depended on the temperature.Between the two sexes,the food consumption of the female was notably higher than that of the male,being10.3 mg and 4.7 mg respectively.The male was higher than the female in approximate digestibility(82.11 % and 78.65%,respectivery)and the growth of body(-5.3 mg and -6.4 mg respectively),but the differences were not significant.
