Fumigant Toxicity and Repellence Activity of Camphor Essential Oil from Cinnamonum camphora Siebold Against Solenopsis invicta Workers (Hymenoptera:Formicidae).

Fu JT, Tang L, Li WS, Wang K, Cheng DM, Zhang ZX - J. Insect Sci. (2015)

Bottom Line: At 2.55 μg/ml, the highest average mortality of the ants was 84.89% after 72 h.Camphor EO exhibited fumigant toxicity against minor and major workers as indicated by the effects on attacking, feeding, and climbing behaviors.This EO was also strongly repellent to the two size workers of the colony as observed in their behavior against Tenebrio molitor treated with 5 µl EO.

iev112-F6: Repellence of the camphor EO to minor and major workers of RIFAs along the time on T. molitor treated with EO at 5 µl/T. molitor.

Mentions: The repellence of camphor EO to RIFAs was presented in Figs. 4 and 6. No significant differences were observed in the percentage of individuals in the Petri dish treatment in terms of exposure time (F = 11.34; P = 0.002) and members of RIFA colonies (F = 11.12; P = 0.012). Camphor EO elicited high repellence for minor and major workers. Approximately 70% of the attack rate of major and minor RIFAs was also reduced. This repellence has also been observed in other insects. As a major component of the EO of aromatic plants, camphor exhibits repellence against Anopheles culicifacies, Culex quinquefasciatus, Anopheles. gambiae, and Anopheles funestus (Ansari and Razdan 1995, Seyoum et al. 2002, 2003). As RIFAs can easily travel in potted plants and vehicles, as well as other places such as nurseries, parks, and truck stops, insect repellent activities of natural substances could be considered as a practical alternative for the control of RIFAs.Fig. 6.
