Feeding and Mobility of the Potato Leafhopper Impaired by Glandular Trichomes of Solanum berthaultii and S. polyadenium 

 -  Journal of Economic Entomology, 71(6), p.856-858, 1978 .
<br/><br/> Glandular trichomes on foliage of 2 wild potato species, Solanum berthaultii Hawkes, and S.polyadenium Greenm., defend against infestation of Empoasca fabae (Harris)by encasing the mouthparts and tarsi with a viscous exudate that rapidly darkens and hardens. Feeding and mobility are impaired, leading to early death and reduced field populations.
