The inhibitory effects of several alcohols identified from male hairpencil of cotton bollworm on conspecific male behavior responses were studied. In the wind tunnel dose tests ranging from 4 × lo p4 to 40 pg , male moths of cotton bollworm produced the highest response to the binary components of 29–16: Ald and Z11 —16: Ald in a ratio of 5 : 95 at the dosage of 0.4 μg. When 211–16:OH was added to 0.4 μg dose of binary blend, 5% of the alcohol completely inhibited male orientation behavior. Further increment of percentage of alcohol in binary blend inhibited not only orientation behavior but also takeoff behavior. Comparisons among 211 —16: OH and other three saturated alcohols, 14 : OH, 16 : OH, and 18 : OH as well as structurally similar compound Z9–16: OH indicated that Z11–16: OH was more effective in inhibiting male orientation behavior than other tested alcohols. Field application of 211–16: OH decreased egg hatch rate from untreated 34% to 17% by spraying or coating the alcohal on plastic tubes.
