Olfactory response ofAnastrepha striata(Diptera: Tephritidae) to guava and sweet orange volatiles

摘要: The behavioral responses of virgin and mated female Anastrepha striata Schiner (Diptera: Tephritidae) to guava (Psidium guajava L.) or sweet orange (Citrus sinensis were evaluated separately using multilure traps in two-choice tests field cages. results showed that flies more attracted volatiles than control (unbaited trap). physiological state (virgin mated) females did not affect their attraction the fruit volatiles. Combined analysis gas chromatography coupled with electroantennography (GC-EAD) volatile extracts both fruits 1 6 compounds from guava, respectively elicited repeatable antennal females. EAD active identified by chromatography-mass spectrometry (GC-MS) as ethyl butyrate, (Z)-3-hexenol, hexanol, hexanoate, hexyl acetate, octanoate. Linalool was only compound extracts. In cage tests, there no significant differences between number captured baited caught 6-component blend formulated according relative proportions Similar occurred when synthetic linalool against From a practical point view, this study could be used for monitoring A. populations.
