Abstract
Lymantria dispar caterpillars were reared under two different rearing
densities for the first three days of the 4th larval instar: 5 larvae that
were kept in a Petri dish (V = 80 ml) belonged to the intense stress (D1
group); 5 larvae that were kept in a plastic cup (V = 300ml) belonged to the
group exposed to less intense stress (D2 group). In the control group, single
larvae were reared in a Petri dish. Morphometric changes in L1, L2 and L2?
dorsolateral neurosecretory neurons (nsn) were analyzed. After keeping 5
larvae in a Petri dish, the size of L2 neurosecretory neurons (nsn)
significantly increased. Rearing 5 larvae in a plastic cup significantly
increased the size of L1 nsn nuclei and the number of L2?nsn. A decrease in
relative band densities in the region of molecular masses (11-15 kD) that
correspond to prothoracicotropic hormones in the gypsy moth was observed in
the electrophoretic profiles that were obtained after both treatments in
comparison to the control group.
