Unsatisfactory quarantine treatment for papayas
Papayas infested with eggs of Dacus cucurbitae and D. dorsalis were subjected to a two-stage hot-water immersion treatment as required by quarantine regulations in the USA.
This quarantine procedure proved to be ineffective against eggs which were oviposited in defective blossom ends of papaya where the holes extended all the way to the seed cavity.
