Methyl Bromide Quarantine Treatment for Persimmon Fruit Moth in Japanese Persimmons

摘要

Complete mortality of larvae of persimmon fruit moth, Stathmopoda masinissa MEYRICK was confirmed by methyl bromide fumigation schedule with 48g/m~3 for 2 hours at 15°C with 50% loading. The results showed that a total of 31,739 larvae in fresh persimmons obtained from pesticide unsprayed orchards were killed completely in 16 replicated tests conducted in 1992-1999. The methyl bromide standard would provide for sufficient quarantine security for exporting Japanese persimmons.
