Abstract:

The carpenterworm moth, Holcocerus arenicola is a serious pest of desert thicket. Cis-7-tetradecen-1-ol (Z7-14: OH), cis-5-tetradecen-1-yl acetate (Z5-14: Ac), cis-7-Tetradecen-1-yl acetate (Z7-14: Ac) and cis-9-hexadeceny-1-yl acetate (Z9-16: Ac) were preliminarily identified by gas chromatography (GC) from its sex pheromone gland extracts. These compounds were chemically synthesized in lab and their biological activities were evaluated in lab and field. The results showed that a blend of Z7-14: Ac and Z5-14: Ac had strong attractive activity. Addition of Z7-14: OH to the blend enhanced slightly the trap catches. The synthetic compounds Z7-14: Ac, Z5-14: Ac and Z7-14: OH in a 10∶8∶1 ratio at 760 μg per trap dosage, set in a triangle trap, were able effectively to attract and kill H. arenicola .

Key words: Holcocerus arenicola, sex attractant, chemical synthesis, biological activity evaluation
