摘      要：Tephritid flies threaten the production of fruits around the *** the Americas,populations of the genus Anastrepha are monitored with trapping networks as part of pest management ***,we report the formulation of male Anastrepha suspensa(Loew)pheromones,(±)-anastrephin and(±)-epianastrephin,into a poly(vinyl chloride)(PVC)polymer-based lure ready for trap *** PVC polymer disks(100 mg)contain 10%by weight of(±)-epianastrephin and(±)-anastrephin in a naturally occurring 7:3 diastereomeric ratio,*** of the pheromones from the disks into an airstream was evaluated as a function of the abiotic environmental parameters,absolute humidity and *** data supports a diffusion-controlled mechanism of release from the matrix with first-order rate constants that decreased about ten-fold as the temperature was lowered from 30 to 15
*** such,the emission of volatile pheromones from the disks is suitable to last for several weeks in the *** kinetic approach,which can be easily extended to the diffusion-controlled release of other attractants from polymeric matrices,yields laboratory predictions of the potential for environmental loss prior to conducting field bioassays.
