METHOD: Oviposition CONDITIONS: Green House - 16h light with 70% RH and 24C METHOD NARR: An antibiosis test was carried out by recording # of pupae and their weight after confining first instar larvae on detached leaves of each pition preference was determined by a 2 X 2 comparison including a control cultivar, and a 4 X 4 comparison only some of which contained the control cultivar. A feeding preference assay was also completed using those accessioting and characterization of trichomes was performed using samples found in the previous tests. RESULTS NARR: A lack of association between trichome A density and antixenosis was demonstrated. No correlations between larvalwas found. All tested clones of pnt exerted some antibiotic effect on the larvae. The pnt clone tested foor antixenosis proved to repel the ovipositing female. Ber genotypes with a high rate of type b trichomes repulsed oviposition.
