Figure 2.

Proportion of male H. armigera selecting linalool (of total number of moths selecting either linalool or phenylacetaldehyde) following conditioning on C. cajan, N. tabacum, A. frutescens or after no conditioning. Numbers of moths responding to odours after training (total number trained in parentheses) are presented under conditioning treatments (not applicable for no conditioning trial). Symbols within bars denote whether proportions were significantly different from 0.5 (equal preference; ^**p<0.005; n.s., not significant). Bars with different letters denote significant differences between treatments (p<0.005), common letters are not significantly different (p>0.05).
