Attractants for Bactrocera latifrons
The Asian species, Bactrocera latifrons (Diptera: Tephritidae) primarily infests fruits of Solanaceae, but has also been found in some Cucurbitaceae. It was introduced in the 1980s into Hawaii (US). Laboratory and field studies on male attractants were done in Hawaii. They showed that a mixture of a-ionol with cade oil (essential oil produced by distillation of Juniperus oxycedrus twigs) was effective. The captures of males at traps baited with this mixture were three times greater than at traps baited with a-ionol alone. Further studies will be made to identify the active ingredient present in essential oil which is responsible for this synergism.
