Genetic variation and correlations of life-history in gypsy moths (Lymantria dispar L.) from two populations in Serbia
Periodic fluctuations in density impose different selection pressures on populations of outbreaking Lepidoptera due to changes in the their nutritional environment. The maternal effects hypothesis of insect outbreak predicts the transmission of this nutritional information to subsequent generations...

Zusammenfassung: | Periodic fluctuations in density impose different selection pressures on populations of outbreaking Lepidoptera due to changes in the their nutritional environment. The maternal effects hypothesis of insect outbreak predicts the transmission of this nutritional information to subsequent generations and alterations in offspring life-history traits. To test for these time-delayed effects of the parental generation, we compared life-history traits and their variation and covariation among laboratory-reared gypsy moths hatched from egg masses collected from low- and medium-density populations. |
