Abstract

Effect of gas mixtures of sulfuryl fluoride and phosphine on forest insect pests.

Abstract

Ten species of forest insect pests were fumigated with mixtures of sulfuryl fluoride (SO2F2, at 30 and 50 g m-3) and phosphine (PH3, at 1 and 2 g m-3) for 24 and 48 hours at 15°C. Fumigation for 24 hours at 15°C resulted in complete mortality in eggs of Callidiellum rufipenne, Monochamus alternatus, Cryphalus fulvus, Ips cembrae and Phloeosinus perlatus, all stages of Scolytoplatypus tycon and Xyleborus validus, while eggs of Semanotus japonicus and Pissodes nitidus, and all stages of X. pfeili, were not killed completely. However, mortality of S. japonicus and P. nitidus, except X. pfeili, was 100% after 48 hours at 15°C.
