Possible Influence of MLP Regulators in Foliage of Host Species on Invasion of Phyllophagous Insects

Abstract

On the northern border of the Gypsy moth area (Lymantria dispar L., 1758), caterpillars are reorient to exogenous regulators of membrane lipid peroxidation in connection with repeated cold periods during feeding. In case of an introduction of host plants with high contents of exogenous regulators of MLP (e.g. Fe2+) in foliage in these areas that may affect diapause duration, the boundaries of spreading and intensity of outbreaks may change.

Na severnoj granici područja rasprostranjenja gubara (Lymantria dispar L., 1758), gusenice se preorijentišu na egzogene regulatore peroksidacije lipada u membrani (MLP) u vezi sa povremenim periodima zahlađenja tokom ishrane. U slučaju uvođenja biljaka domaćina koje imaju povećane sadržaje egzogenih regulatora MLP (npr. Fe2+) u listovima, koji mogu uticati na dužinu dijapauze, mogu se promeniti granice rasprostranjenja i intenzitet napada.
