Effects on lepidopteran herbivores of feeding on leaves of transgenic birch (Betula pendula) expressing the sugar beet chitinase IV gene

open access: yesEuropean Journal of Entomology, 2013
Transgenic lines of silver birch (Betula pendula) carrying the sugar beet chitinase IV gene were used to study the effects of the heterologous expression of a transgenic chitinase on the performance of lepidopteran herbivores.

Determination of female-biased sexual size dimorphism in moths with a variable instar number: The role of additional instars

open access: yesEuropean Journal of Entomology, 2006
While the ultimate causes and adaptive significance of sexual size dimorphism (SSD) have been extensively studied, the developmental mechanisms behind this phenomenon have received little attention.

Pre-adult development and longevity in natural populations of Lymantria dispar (Lepidoptera: Lymantriidae)

open access: yesEuropean Journal of Entomology, 2007
While most theoretical models for the evolution of ageing assume that duration of pre-adult development does not affect the longevity, experimental data are still controversial and inconsistent.

Size-dependent colouration in larvae of Orgyia antiqua (Lepidoptera: Lymantriidae): A trade-off between warning effect and detectability?

open access: yesEuropean Journal of Entomology, 2007
While the study of colour patterns is a traditional subject of evolutionary ecology, there are various hypotheses which suffer from a lack of experimental evidence.
