Abstract
Resistance in accession PI 134417 of Lycopersicon hirsutum f. glabratum to Manduca sexta L. results from the presence of the methyl ketones 2‐tridecanone and 2‐undecanone in the type VI trichome glands on foliage of these plants. Short (24 h) and long term (neonate to adult) laboratory experiments using M. sexta‐resistant and susceptible foliage and methyl ketone treated filter paper disks were conducted to evaluate the direct (plant‐mediated) and indirect (prey‐mediated) effects of this resistance on two predators of Helicoverpa zea eggs, Coleomegilla maculata (DeGeer) and Geocoris punctipes (Say). Direct effects of resistance were manifest as reduced egg consumption and increased mortality for both predators. Indirect effects were manifest as reduced egg consumption by G. punctipes, but were not observed for C. maculata. Results of experiments using methyl ketone‐treated filter paper disks instead of foliage were similar.This publication has 25 references indexed in Scilit:
