Abstract
The roles of type A and B gladular trichomes in defense of the wild potato species, Solanum berthaultii Hawkes, agamst the green peach aphid, Myzus persicae (Sulzer), and Potato leafhopper, Empoasca fabae (Harris), were assessed. Mortality of fourth-stadium M. persicae and encasement of tarsi and labia by type A exudate increased with a rise in density and volume of type A trichomes. Tarsi coated by type B exudate were highly adhesive and extremely effective in discharging type A trichomes. Immature stages of M. persicae and E. fabae were subject to greater mortality and encasement of body parts by trichome exudate than were adults.This publication has 1 reference indexed in Scilit:
