Abstract
The effects of buprofezin on the life span and reproduction of N. lugens were examined by allowing adults of different ages to feed on rice plants treated with the chemical. Irrespective of adult age at the time of inoculation on the treated plants, the number of nymphs of the next generation was decreased to 0-6% of the control by 250 ppm buprofezin and to 0-2% by 1, 000 ppm. The treatment to adults within 24 hr of emergence considerably inhibited oviposition without interrupting ovarian development and shortened the life span of female adults. Although the treatment to older adults did not affect oviposition, it inhibited the embryo development of deposited eggs, which reached the eye pigmentation stage but failed to hatch.
