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 and placed in the pitaya orchards using a completely randomized design. As a result, four species of Lonchaeidae were trapped, namely: D. saltans, Lonchaea cristula, Neosilba batesi and Neosilba sp. Hydrolyzed corn protein captured the highest number of loncheids, followed by commercial soy sauce and hydrolyzed soy protein (without monosodium glutamate) respectively. Of the captured species of Lonchaeidae, only D. saltans is known to cause damage on flower buds. Whilst, very few individuals of D. saltans were caught in McPhail traps baited with the above attractants compared to the other trapped Lonchaeidae, and there is a great difficulty for the differentiation of loncheid species in the field with the naked eye, thus McPhail traps baited with these hydrolyzed proteins are not recommended as a population monitoring system nor for taking decisions on pesticide applications. Key words: bait, Selenicereus megalanthus, McPhail trap, trapping, Cactaceae.
