Abstract

The sensitivity of Xylosandrus germanus (Bldf.), X. compactus (Eichh.) and Xyleborus crassiusculus (Motsch.) (semiopacus Eichh.) to irradiation was tested in the laboratory in Japan with a view to the possibility of using radiation for control of ambrosia beetles in cut timber. The LD50's and LD99's for females, determined 12 days after treatment, were 39 and 73 krad, 50 and 91 krad and 94 and 130 krad for the 3 species, respectively. Doses that prevented adult emergence in all species were 3 krad for 5-day-old eggs, 5-7 krad for third-instar larvae and over 10 krad for pupae. The sterilising dose was 2-4 krad for all stages of all the species. Xylosandrus females that mated soon after emergence and were then exposed to 2-4 krad produced only male offspring. Treatment of adults and pupae with 10-30 krad effectively prevented the production not only of progeny surviving to the adult stage but also of further boring damage.
