METHOD: Life Cycle CONDITIONS: Green House - 16h light at 20-26C, RH 60-90% METHOD NARR: Plants were grown in a GH and leaves were removed as needed for each of the different assays. Feeding behavior of GPA was examined with anechnique. The number of probes, preprobe time and total probing time were recorded. Survivorship and fecundity data were obtained on intact leaflets by measuring length of stadia, adult life span, age at first reproduction, and total reproduction. Droplets of type B trichomes were removed and the same life cycle parameters as above were collected. Rate of type B droplet regeneration was determined. Phenolic oxidation activity in trichomes was d Densities of both types of glandular trichomes were significantly less on ncd than on ber. Type B droplets of ncd were significantly larger than those of ber. Regeneration of droplets, after removal, to original dimensions by day 52 was nearly 100%. Preprobe time on ncd was significantly delayed but total feeding time did not differ from tbr. Net replacement rate of GPA was 1.3 on ncd, 5.2 on tbr and 8.2 on ber473334 and there was no reproductions intermediate to tbr and ber310927. Fecundity and the mean number of offspring produced per aphid per day was greater on ncd than tbr. Length of developmental period and survival increased with removal of type B exation activity of ncd was similar to tbr (low) while that of ber was high. AUTHOR EXPLANATION: These findings demonstrate that type B glandular trichomes play an important role in the resistance of ncd to GPA.d survivorship on ncd reflects stress associated with immobilization and struggling in the encounter with very large droplets of extrem
