Abstract

Abstract:

This study clarifies the preference of newly emerged Pachyrhinus yasumatsui adults for different jujube cultivars, and provides basic data for elucidating the chemical communication mechanism of host orientation and screening resistant varieties of jujube trees. In this experiment, using jujube buds, branches, and leaves of five jujube varieties as plant materials, the olfactory behavioral responses of P. yasumatsui adults to the volatiles of the above plant materials were measured by a Y-tube olfactometer and a disc trap olfactometer. The results of Y-tube olfactory test showed that with the clean air as control, the selection rate of five jujube bud volatiles by P. yasumatsui adults was 69.0%-79.2%. The volatiles from five jujube buds had significant attraction to P. yasumatsui adults (P<0.05), while volatiles from ‘Muzao' buds had extremely significant attraction to adults (P<0.01). The number of odor arms of the five jujube leaves selected by adults was not significantly different from that of the air control arm (P>0.05). The selection rate of volatiles emanating from five jujube branches by P. yasumatsui adults was 66.7%-75.0%, and volatiles from jujube branches of ‘Muzao', ‘Goutouzao', ‘Suanzao' and ‘Junzao' had significant attraction to adults (P<0.05). The results of disk trap olfactory test showed that P. yasumatsui adults had obvious selectivity for volatiles from buds and branches of different jujube cultivars. The selection rate of P. yasumatsui adult for buds and branches of ‘Muzao' was significantly higher than that of air control (P<0.05). The selection rate of female adult to the buds and branches of ‘Zanhuangzao' and ‘Junzao' was not significantly different from that of air control. In conclusion, the volatiles from buds and branches of ‘Muzao' have the strongest attraction to P. yasumatsui. ‘Muzao' has the weakest resistance to P. yasumatsui, while ‘Zanhuangzao' and ‘Junzao' have stronger resistance to them.
