Abstract:"Mating experience could not affect the production of sex pheromone in the female glands 24 h later, which meant that the beet armyworm females might call and mate again in next scotophase. This result explained the phenomenon why the beet armyworm could mate several times in their life under field conditions. On the contrary, ambient temperature greatly influenced the pheromone biosynthesis in the beet armyworm females. The optimal temperature for the biosynthesis of sex pheromone was between 15-25 degrees C. Under the temperature beyond this range, the biosynthesis of the pheromone components was disturbed in terms of absolute titers, proportions, and their CVs. The biosynthesis of component B was suppressed under 35 degrees C, and the proportion of A to B was significantly higher. In contrast, under 10 degrees C, the titer of A and the proportions of A to B were disturbed significantly, and the proportions of A in AB and AD binary blends changed significantly. Furthermore, the CVs of the ratios of A to B and A to D became larger than 10% under 10 degrees C"
