This thesis focuses on flavonoids, a subgroup of phenolic compounds produced by plants,
and how they affect the herbivorous larvae of lepidopterans and sawflies. The first part of the …

Larvae of nine species of sawflies (Symphyta) were fed with the foliage of three birch
species, after which the larval hemolymph composition was studied by HPLC–DAD and …

Lepidopteran larvae encounter a variety of phenolic compounds while consuming their host
plants. Some phenolics may oxidize under alkaline conditions prevailing in the larval guts …

Jeffrey Harborne and colleagues have been responsible for collating the majority of data on
the role of flavonoids in insect–plant interactions. This article examines some of this …

We investigated the biochemical transformation of individual phenolic compounds of
mountain birch leaves in larvae of six birch-feeding sawfly species: Amauronematus amplus …

The use of insects in traditional medicine and unveiling the chemical structure of the bright
pigments in butterfly wings led to the discovery of bioactive phenolic compounds in the …

The metabolic modifications of birch (Betula pubescens Ehrh.) leaf phenolics in the digestive
tract of its major defoliator, larvae of the autumnal moth Epirrita autumnata, were studied …

Early instars of gypsy moth (Lymantria dispar L.) generally do not feed on pine (Pinus)
species, perhaps due to secondary compounds found in pines. To test this hypothesis …

Attempts to characterize tannin activity in biological systems have met with mixed success.
Although there are many examples in which tannins inhibit fungal, bacterial, and/or viral …
