众所周知，雄性诱蚊剂是许多伤寒果蝇种类的首选诱蚊剂，由于其高特异性和在大范围内吸引苍蝇的能力，通常比基于食物的诱捕器更受欢迎。α -离子醇已被鉴定为一种雄性诱蚊剂，用于引诱麻风果蝇小实蝇。然而，这种化合物对雄性latifrons个体的吸引力不如其他麻风果蝇对各自雄性诱饵的吸引力那么强。凯德油是一种由杜松（Juniperus oxycedrus L.）树枝的破坏性蒸馏产生的精油，它能协同α -离子醇对雄性白桦的吸引力。用-离子醇和油混合诱捕器诱捕的雄性白腹小蠊的渔获量是单独诱捕器诱捕量的3倍以上。在检测程序中用α -离子醇+ cade油代替α -离子醇可以显著提高检测入侵种群或早期种群的机会。然而，检测程序不应仅仅依赖于这种诱饵，还应利用蛋白质诱捕器和水果收集。进一步的研究可能有助于鉴定其有效成分，从而进一步改善这种雄性诱饵的效果。
Male lures are known for many tephritid fruit fly species and are often preferred over food based traps for detection trapping because of their high specificity and ability to attract flies over a wide area. Alpha-ionol has been identified as a male lure for the tephritid fruit fly Bactrocera latifrons (Hendel). The attraction of this compound to male B. latifrons individuals, however, is not as strong as is the attraction of other tephritid fruit fly species to their respective male lures. Cade oil, an essential oil produced by destructive distillation of juniper (Juniperus oxycedrus L.) twigs, synergized the attraction of alpha -ionol to male B. latifrons. Catches of male B. latifrons at traps baited with a mixture of alpha -ionol and cade oil were more than three times greater than at traps baited with alpha -ionol alone. Substitution of alpha -ionol + cade oil for alpha -ionol alone in detection programs could considerably improve the chance of detecting invading or incipient populations of B. latifrons. However, detection programs should not rely solely on this lure but also make use of protein baited traps as well as fruit collections. Further work with fractions of cade oil may help to identify the active ingredient(s), which could help to further improve this male lure for B. latifrons.
