Plant Glucosinolate Content and Host-Plant Preference and Suitability in the Small White Butterfly (Lepidoptera: Pieridae) and Comparison with Another Specialist Lepidopteran.

Glucosinolates are used in host-plant recognition by insects specialized on Brassicaceae, such as L. (Lepidoptera: Pieridae). This research investigated the association between oviposition and larval survival and host-plant glucosinolate content using 17 plant species in which glucosinolate content had previously been determined.

Plant-Insect Interactions.

The central part of the study of plant-insect interactions comes from our quest for knowledge on why and how these interactions occur [...

Glucosinolate Induction and Resistance to the Cabbage Moth, , Differs among Kale Genotypes with High and Low Content of Sinigrin and Glucobrassicin.

The cabbage moth, L. (Lepidoptera: Noctuidae), is a generalist insect pest of cruciferous crops. We tested glucosinolate induction by jasmonic acid (JA) and salicylic acid (SA), and by these phytohormones combined with feeding by larvae in four genotypes of kale, L.

Phylloplane location of glucosinolates in Barbarea spp. (Brassicaceae) and misleading assessment of host suitability by a specialist herbivore.

Glucosinolates are plant secondary metabolites used in host plant recognition by insects specialized on Brassicaceae, such as the diamondback moth (DBM), Plutella xylostella. Their perception as oviposition cues by females would seem to require their occurrence on the leaf surface, yet previous studies have reached opposite conclusions about whether glucosinolates are actually present on the surface of crucifer leaves. DBM oviposits extensively on Barbarea vulgaris, despite its larvae not being able to survive on this plant because of its content of feeding-deterrent saponins.
