COMPARATIVE BEHAVIORAL RESPONSES OF Β-CARYOPHYLLENE AGAINST ANOPHELES MOSQUITO SPECIES, POTENTIAL VECTORS OF MALARIA IN THAILAND.
Insecticide-based mosquito control poses risks of environmental harm and resistance development. As a safer alternative, β-caryophyllene, a nontoxic compound derived from plants, was evaluated as a safer alternative for its excito-repellency against four Anopheles mosquito species. Using an excito-repellency assay, An. minimus showed the highest escape rates (100%) at 2.5% (contact) and 5% (noncontact) concentrations. An. harrisoni also exhibited strong responses at 7.5%, with 94.34% (contact) and 72.73% (noncontact) escape. In contrast, An. epiroticus showed minimal response (12-25.42%). Significant differences between contact and noncontact trials were noted only in An. minimus and An. harrisoni. No knockdown or mortality occurred. Kaplan-Meier analysis revealed faster escape in contact conditions, especially for An. minimus. Log-rank tests confirmed dose-dependent repellency effects. These findings suggest β-caryophyllene has promising potential as a natural spatial repellent against malaria vectors.
期刊介绍：
The Journal of the American Mosquito Control Association (JAMCA) encourages the submission
of previously unpublished manuscripts contributing to the advancement of knowledge of
mosquitoes and other arthropod vectors. The Journal encourages submission of a wide range of
scientific studies that include all aspects of biology, ecology, systematics, and integrated pest
management. Manuscripts exceeding normal length (e. g., monographs) may be accepted for
publication as a supplement to the regular issue.
