    Pupae of the bean webworm, Pleuroptya ruralis, were collected from soybean fields in Toyama and Niigata, and the sex pheromone glands were removed from 24 virgin females that emerged from the pupae. The extract from sex pheromone glands was analyzed by GC-EAD and GC-MS, and then (E)- and (Z)-10-hexadenal were realized as candidates of the sex pheromones. Forty-five feral males were captured with a white sticky trap baited with an 84 : 16 mixture of (E)- and (Z)-10-hexedecenal from 14 to 29 July 2005 in Toyama. These results suggest that the mixture of aldehydes is a sex attractant of the bean webworm.

    In order to examine the daily periodicity of the attraction of males to females in the sorghum plant bug, Stenotus rubrovittatus, males captured on sticky traps baited with 10 virgin females were investigated every four hours. Male bugs were captured in traps, but the number of males captured was none or few from noon to four o'clock in the afternoon in a day. This result suggests the daily periodicity of attraction of males to females. To examine the daily periodicity of mating, thirty pairs of virgin adults six days after emergence were released into a rearing cage in the laboratory at different times of day. The number of mated females was checked 4 h later. The percentage of mated females did not differ regardless of the time of release and the light conditions. This result suggests that there is no daily periodicity in mating.

    To establish a simple method for discriminating Okinawa and Ogasawara strains of the sweet potato weevil, Cylas formicarius, about 560 bp of the internal transcribed spacer-1 (ITS-1) region of the ribosomal DNA (rDNA) of C. formicarius was collected from several islands of Okinawa Prefecture and Ogasawara Islands and analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The 345 weevils collected in Okinawa and Ogasawara were discriminated correctly by the RFLP patterns with the restriction enzyme RsaI. The results suggest that C. formicarius originating from Ogasawara Islands is an effective genetic marking strain for an eradication project using the sterile insect technique implemented by the Okinawa prefectural government.
