Interpretive Summary:
- Exotic
quarantine pests like fruit flies represent one of the greatest
threats to California agriculture if populations of these pests
were to become established in the state. Quarantine security
against these pests in a variety of agricultural commodities
is presently ensured by 2 to 4 hr fumigation treatments using
methyl bromide. Because methyl bromide production is being phased
out, we tested the effectiveness of sulfuryl fluoride as an
alternative treatment against the Mediterranean fruit fly, Ceratitis
capitata Wiedemann, the Oriental fruit fly, Bactrocera dorsalis,
and the Melon fly, B. cucurbitae. Results of our laboratory
tests showed that sulfuryl fluoride was very toxic to larval
stages of each of the 3 species of fruit fly in 4 hr fumigations.
Conversely, eggs of these fruit flies were relatively tolerant
to sulfuryl fluoride in the short, 4-hr exposure periods. Effective
control of the eggs would require exposures to sulfuryl fluoride
of 24 to 48 hrs. These results indicate
that sulfuryl fluoride is not an effective replacement of methyl
bromide as a quarantine fumigant for these fruit flies because
of the relative tolerance of the egg stage in short exposure
periods.
