Abstract

Abstract: The haemolymph ecdysteroid titres of the last instar and diapausing prepupa of the sawfly Chinolyda flagellicornis were determined by radioimmunoassy. The results showed that two peaks were present on the second and the fourth day of the last instar respectively. The haemolymph ecdysteroid titres of diapausing prepupa remained at a relatively high level (about 20 ng/mL). From about one week before pupation (the last instar) haemolymph ecdysteroid titres went up forming two separated peaks. It seems that the diapause of Chinolyda flagellicornis is regulated by ecdysteroids.

Key words: Chinolyda flagellicornis, ecdysteroid, radioimmunoassay
