“…The calling females exhibit a calling posture by extruding the pheromone gland while bending the abdomen dorsally. This calling posture is similar to that of other crambid moths, e.g., Chilo suppressalis 23 , Dichocrocis punctiferalis 16 , Glyphodes pyloalis 20 , and Diaphania indica 15 . The number of females that performed the calling posture was recorded at 1-h intervals during the observation period.…”

The rice leaf folder, Cnaphalocrocis medinalis, showed a circadian rhythm in its calling behavior at 25 ± 1 o C. Female moths showed calling behavior most frequently 5-7 h into the scotophase under LD 15:9. Female moths at age 4 (days), after entraining at LD 15:9, showed a free-running rhythm for at least two more cycles in continuous darkness. The rhythm was damped out in constant light. The temporal pattern in the calling behavior was affected by different LD cycles (LD 15:9, 12:12, and 9:15), indicating that the rhythm in calling behavior was entrained by the LD cycles. By changing one photoregime condition to another after calling had been initiated, it was shown that C. medinalis females use the light-off signal to phase-set the circadian rhythm of calling behavior. Our results suggest that the rhythm in calling behavior is a circadian rhythm entrained by LD cycles.

“…A rubber septum soaked with a 0.6 mg synthetic sex pheromone mixture containing (Z)-11-hexadecenal, (Z)-13-octadecenal, and (Z)-9-hexadecenal at a ratio of 48 : 6 : 5 (Shin-Etsu Chemical Co. Ltd., Tokyo) was used as an attractant. Although this pheromone blend was identified as a sex pheromone for insects collected from rice (Tatsuki et al, 1983), the blend also showed comparable attractiveness to males of the water-oats population (Tsuchida and Ichihashi, 1995). We replaced sticky traps almost weekly, and rubber septa monthly.…”

The striped stem borer moth, Chilo suppressalis, consists of two host-associated populations: a rice-feeding population and a water-oats-feeding population. We investigated the seasonal occurrence of each population using sex pheromone traps in paddy fields and adjacent water-oats vegetation. Trapped males were individually classified into their respective populations by morphometric analyses of genitalia. Although the first flight of the water-oats population was long, with 1 to 3 poorly resolved peaks during April to June, that of the rice population was much shorter, with a sharp peak in early June. This result supports previous observations that adults of the overwintering generation of the water-oats population occur about two months earlier than those of the rice population; however, it is uncertain how this difference enhances reproductive isolation between the two populations because the occurrence overlaps.

“…The female sex pheromone of the rice stem borer Chilo suppressalis was first identified as a mixture of (Z)-ll-hexadecenal and (Z)-13octadecenal (Nesbitt et al, 1975;Ohta et al, 1976) but failure of this blend to attract males to the same extent as live virgin females suggested the presence of other synergistic components, and subsequently (Z)-9-hexadecenal, a positional isomer of (Z)-ll-hexadecenal, was identified (Tatsuki et al, 1983). This enormously increased the attractant properties of the existing two-blend formulation to male moths in the field and since then the three-blend mixture has formed the basis of experimental and commercial development of controlled release formulations combining aldehyde-stablizing agents (Tatsuki, 1990).…”
