Abstract:

An ethylene dibromide-hot water dip treatment for destroying fruit fly infestations and controlling anthracnose rot in papayas is described. Submerging the fruits for 20 minutes in a solution containing l08 or 120 mg. of EDB (ethylene dibromide) per litter of water at temperatures of 115° or 110., respectively, gave mortality of fruit flies exceeding 99.9968%, equal to a probit of 9.0 Most of the organic bromides were lost or converted to inorganic bromides within 3 days after treatment. Continued use could be made of a dip by replacing lost amounts of EDB or starting with an excess of fumigant in the mixture. Posttreatment cooling in cold water did not appear to influence the effectiveness of dosages needed for quarantine security. When complete immersion to control anthracnose was not necessary, fruits were floated in the solution without decreasing mortality of fruit flies. Increasing the concentrations of EDB in the dip permitted use of lower temperatures or shorter time intervals for effective control of fruit fly infestations but not for postharvest rot.
