M. Slovak et al., HEAVY-METALS AND FLUORINE INFLUENCE ON ARYLPHORIN SYNTHESIS IN THE CABBAGE MOTH (MAMESTRA-BRASSICAE, LEPIDOPTERA, NOCTUIDAE), BIOLOGIA, 50(5), 1995, pp. 501-506
Semisynthetic diet contaminated by Cd, Pb, Cu and F was administered t
o cabbage moth larvae: a) on a single occasion, after moulting to the
sixth instar b) continually, from the fourth instar onwards. Changes o
f the arylphorin concentration in the haemolymph of larvae and pupae w
ere determined by means of ELISA. Toxic diet significantly reduced the
arylphorin concentrations in the haemolymph of larvae (except of thos
e continually fed on F and a lower concentration of Cu). There were no
significant differences in the haemolymph arylphorin concentrations o
f pupae, the larvae of which had previously received a single dose of
toxic feed. On the other hand, the arylphorin concentrations of pupae
with larvae under continual toxic pressure were significantly lower (C
d) or higher (Cu).
