Preliminary studies were conducted on the potential for hot water, methyl bromide with or without cold storage, and gamma irradiation as quarantine treatments against eggs of Asynonychus cervinus [Pantomorus cervinus] on oranges intended for export to Japan. There was complete inhibition of egg hatch when infested Valencia oranges were dipped in water at 46 deg C for 75 min but there was severe damage to the fruit. Water dips at 50 deg C for 2 and 10 min and 52 deg C for 2 and 7 min reduced egg hatch by up to 66% with no fruit damage. Fumigation with 20 g/m3 methyl bromide (MB) for 2 h at 17 deg C followed by storage for 8 days at 1 deg C reduced egg hatch by 45%. Fumigation with 45 g/m3 MB at 17 deg C for 2 h and irradiation at 300 Gy reduced egg hatch by 98% and 95%, resp.
