摘要：

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 Fuller's rose weevil on oranges intended for export to Japan. There was complete inhibition of egg hatch when infested Valencia oranges were dipped in water at 46-degrees-C for 75 min but there was severe damage to the fruit. Water dips at 50-degrees-C for 2 and 10 min and 52-degrees-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-degrees-C followed by storage for 8 d at 1-degrees-C reduced egg hatch by 45%. Fumigation with 45 g/m3 MB at 17-degrees-C for 2 h and irradiation at 300 Gy reduced egg hatch by 98% and 95%, respectively.
