| Abstract: | Prompted by the previous discovery that (9Z,11E,13E)-9,11,13-octadecatrienoic acid (α-eleostearic acid) was one of the compo-nents responsible for the boll weevil feeding deterrency of tung oil, the seeds of 11 other plant species were extracted with pentane and the oils were evaluated for their feeding deterrency in the laboratory. The oils ofCalendula suffruticosa, Centrantbus macro-siphon, Jacaranda mimosifolia andMomordica cochincbinenis were effective feeding deterrents for the boll weevil. |
