title: Hooked trichomes: a physical plant barrier to a major agricultural pest.
abstract: Hooked epidermal appendages (trichomes) on leaves of field bean cultivars effectively capture nymph and adult leafhoppers. Frequency of capture and capture mortality are highly correlated with trichome density. Hooked trichomes inserted at angles less than 30 degrees are ineffective in capture.
