Abstract: Moths of the armyworm Pseudaletia unipuncta have been found to be attracted strongly to mixtures of three or four chemical compounds. The mixtures found to be the most powerful and specific attractants are those comprising:(a) (Z)-11-hexadecenyl acetate(b) (Z)-11-hexadecenol and(c) (Z)-11-hexadecenal, preferably with(d) (Z)-9-tetradecenyl acetate.The respective weight ratios for the best effect were found to be approximately 10000:20:4:1.

Abstract: A cone-orifice insect trap comprising an intermediate annular member carrying a lure and two truncated-cone-shaped casing members with perforated, funnel-shaped, insect trapping end walls extending inwardly from each end of the casing members. The modular construction ensures ease of assembly while the casing members may be nested together to avoid occupying an unduly large volume during, for example, transport. Close manufacturing tolerances for the insect trap entrances and positioning the lure reduce trap-to-trap performance variability. The trap has a long field life and a wide variety of uses.

Abstract: Mixtures of two compounds Z-11-hexadecen-1-ol acetate (A) and Z-9-tetradecen-1-ol acetate (B) exhibit high and species specific attractancy for the male Bertha Armyworm moth. The optimum attractant and specificity effect has been observed at proportions of about 95% A and 5% B. A dose of about 0.1 to 10 mg of the attractant per insect trap has been found effective. Neither A nor B alone are good attractants for the Bertha moth, although A alone has slight attractancy.
