Quarantine treatment against Anastrepha suspensa
A new quarantine treatment against Anastrepha suspensa (EPPO Al pest) in carambolas has been developed in the USA.
Infested carambolas were treated with hot air at a temperature of 47° C at an air flow rate of 0,75 m3s-1. Probit 9 (99,9968% mortality estimate) was reached when the carambolas were subjected for about 65 minutes to the hot-air treatment. The treatment did not damage the fruit quality and is, therefore, considered more practicable than the vapor-heat treatment or the hot-water immersion treatment.
