A list of organisms associated with yellow pitaya crop, Selenicereus megalanthus (K. Schum. ex Vaupel) Moran in Colombia is provided. The main pests of yellow pitaya in Colombia are the flower-bud fly Dasiops saltans Townsend (Diptera: Lonchaeidae) and Leptoglossus zonatus (Dallas) (Hemiptera: Coreidae). In this study we report 29 organisms affecting yellow pitaya: 4 Classes, i.e., Arachnida (1 sp.), Aves (1 sp.), ...

The lack of postharvest alternatives to maintain pitahaya quality is partly responsible for the technological limitations to better position the fruit for international commercialization. Cold temperatures from harvest to the consumer are the best option for quality assurance but it is not economically attractive because of the high cost of refrigeration. A prototype storage system suited for the pitahaya producers was ...

The absence of economically competitive alternative technologies for the preservation of pitahaya fruits has slowed the development of this fruit agrochain in the country. Colombia is one of the main pitahaya producers but with a minimal market share. Post harvest management deficiencies are reflected in a short shelf life, significant postharvest losses and a wide price fluctuation, which limits the agrochain growth ...

Three baits for trapping the pitaya flower-bud fly, Dasiops saltans Townsend (Diptera: Lonchaeidae) in yellow pitaya, Selenicereus megalanthus (Cactaceae) orchards were evaluated. The tested baits were hydrolyzed soy protein (without monosodium glutamate), hydrolyzed soy protein with monosodium glutamate (commercial soy sauce), and hydrolyzed corn protein (without monosodium glutamate), which were put into McPhail traps ...
