Rhythms of pheromone titer in 2 sugarcane pest species Chilo sacchariphagus and Chilo infuscatellus (Lepidoptera: Crambidae).

ABSTRACT: Chilo sacchariphagus Bojer and Chilo infuscatellus Snellen are 2 major sugarcane pests in southern China. Both species are nocturnal moths that exhibit sexual activity during the night. However, the rhythms of their sexual activities remain poorly documented. In this study, we investigated the sex pheromone titers of both species to determine the effect of age on pheromone production and to characterize the rhythms of pheromone production during the scotophase, when the highest levels are expected to occur. Gas chromatography-mass spectrometry analysis of hexane extracts from female pheromone glands revealed that the titers of 3 sex pheromone components, (Z)-11-hexadecenyl acetate (Z11-16: Ac), (Z)-13-octadecenyl acetate (Z13-18: Ac), and (Z)-13-octadecen-1-ol (Z13-18: OH) were very low on
