Quarantine treatment against Anastrepha suspensa

The mortality of larvae of A. suspensa infesting mangoes was compared when a hot water quarantine treatment was followed either by an immediate hydrocooling procedure or by air cooling.
The two cooling procedures were not significantly different but one larva survived the hot water treatment followed by hydrocooling.
The same cooling procedures were applied after carambolas infested with Anastrepha suspensa were subjected to a vapour - heat treatment.
The vapour-heat treatment combined with the air cooling procedure achieved a sufficient mortality rate of A. suspensa (probit 9). Rapid hydrocooling, however, reduced larval mortality.
