Potential efficacy of a natural compound (anethole) against Ceratitis capitata
Anethole is an aromatic ether present in high concentrations in the essential oil of fennel (Foeniculum vulgare). Useful biological activity of this compound has been observed on pathogenic fungi, insects (Coleoptera, Diptera, Hymenoptera) and mites. During preliminary studies, it was observed that sugar solutions containing anethole were very attractive to Ceratitis capitata (EPPO A2 quarantine pest) and that their ingestion produced clear signs of systemic toxicity. Further laboratory studies were conducted in Italy to assess the efficacy of anethole mixed with three different commercial protein baits. High values of mortality (85% after 24;h) were obtained after oral administration to adults. A total inhibition of reproductive activity was also observed. The authors felt that their preliminary results are very promising, and further testing in the field is necessary.
