DEVELOPMENT AND FECUNDITY OF ORIUS-SAUTER I (POPPIUS) (HEMIPTERA, ANTHOCORIDAE) REARED ON APHIS-GOSSYPII GLOVER AND CORN POLLEN

The developmental time and survival rate of nymphs, and the longevity and fecundity of adult females of Orius sauteri (POPPIUS) were examine d using tile following three diets at 25 degrees C, 15L-9D conditions : Aphis gossypii GLOVER (aphid), corn pollen (pollen) and pollen + aph id. The developmental time and survival rate (in parentheses) of nymph s fed on aphid, pollen and pollen + aphid, were 14.9 days (90.0%), 17. 2 days (21.2%) and 13.3 days (93.3%), respectively. The mean total num ber of eggs deposited per female was 29.2 on aphid, 15.4 on pollen and 30.4 on pollen + aphid. The mean longevity of females was 15.3 days o n aphid, 10.1 days on pollen and 16.3 days on pollen + aphid. These re sults suggest that corn pollen alone is not sufficient for rearing O. sauteri. However, Aphis gossypii is a sufficient dirt for rearing this species, compared to Thrips palmi a suitable diet reported by NAGAI ( 1993).
