Abstract

Sex gland extracts of Ostrinia nubilalis females collected in the wild or laboratory-reared from Switzerland, Italy, and Hungary were analyzed. Individuals collected in the north of Switzerland contained (Z)- and (E)-11-tetradecenyl acetate at the approximate ratio of 97:3 (Z type), in accordance with field responses of males and previous findings. On the other hand, females from a laboratory culture derived from field collections made in the same area and reared for four to five generations contained the Z and E isomers at ratios of ca. 3:97 and 35:65, respectively. In the south, one of the eight wild females analyzed was of the Z type and the rest intermediate, whereas males were predominantly trapped with blends of the two isomers containing 60 to 97 E. In a laboratory culture reared for one to two generations from corn borers collected in Hungary, three of nine females were of the intermediate type and the rest Z. Small amounts of (Z)-11-hexadecenyl acetate were detected in female glands of the E strain; however, no effect of this compound could be observed in the field.
