METHOD: Life Cycle CONDITIONS: Green House - 16h light at 20-26C with 60-90% RH METHOD NARR: Neonate larvae were caged on plants. Some of the ncd had exudate of trichomes removed by wiping. Living and dead larvae were recorded. and relative consumption rate were calculated. Oviposition behavior was also examined. In field trials 2 ber accessions were added to the ncd and tbr groups for defoliation assessment. RESULTS NARR: Larvae confined to night, and experienced significantly higher mortality than on tbr. Removing exudate did not improve survival. On ncd, most larvae died as first instars and those that survived, did not complete the second stadium in the time alncd contained few eggs and those females fed on ncd virtually ceased oviposition. Defoliation of ncd was very low and were < or = to ber. AUTHOR EXPLANATION: Resistance appears to be largely independent of glandular trichomes. Feeterred and it is difficult to determine the relative importance of behavioral inhibition versus metabolic toxicity since few larvae fed sufficiently to allow accurate determination of growth efficiency.
