Oviposition, larval survival and leaf damage by the willow leaf blotch miner, Micrurapteryx salicifoliella, in relation to leaf trichomes across 10 Salix species

摘要

1. Foliar trichomes clearly reduce chewing damage and efficiency of movement by some insect herbivores, but the effect of trichomes on insect oviposition is less well characterised. Trichomes are likely to have particularly strong, negative effects on species that require secure attachment of the egg to the leaf epidermis for successful transition to the feeding stage - a group that includes many leaf mining insects.
