Development and Fecundity of Orius sauteri (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 examined using the following three diets at 25°C, 15L-9D conditions: Aphis gossypii GLOVER (aphid), corn pollen (pollen) and pollen+aphid. The developmental time and survival rate (in parentheses) of nymphs 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 number or 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 on aphid, 10.1 days on pollen and 16.3 days on pollen+aphid. These results suggest that corn pollen alone is not sufficient for rearing O. sauteri. However, Aphis gossypii is a sufficient diet for rearing this species, compared to Thrips palmi, a suitable diet reported by NAGAI (1993).
