Sulfuryl fluoride fumigation against wood pests
Studies were carried out in Japan on the efficacy of sulfuryl fluoride, as an alternative to methyl bromide fumigation, against 7 species of forest pests;: Semanotus japonicus, Callidiellum rufipenne, Monochamus alternatus (EPPO A1 quarantine pest), Cryphalus fulvus, Ips cembrae (EU Annex II/B), Phloeosinus perlatus, Sirahoshizo sp. Five to seven different doses were applied at 15 °C during 24 h (larval, pupal and adults stages) and during 48 h (eggs). It was observed that the most resistant stage was the egg stage in all species, and the most resistant eggs were those of Cryphalus fulvus. It was estimated that in order to obtain 100 % mortality of C. fulvus eggs, the practical dose of sulfuryl fluoride should be at least 130 g/m3 and applied for 24 h at 15 °C. However, it is felt that this high dose may not be practical in normal quarantine fumigation units and that further studies under higher temperatures or using mixtures with other fumigants are needed.
