SOTO-GIRALDO, Alberto. Olfactory response of Trigonospila unicaldasi (Díptera: Tachinidae) to volatiles from citrus plants attacked by Compsus viridivittatus (Coleoptera: Curculionidae) and sprayed with calcium polysulfide. Bol. Cient. Mus. Hist. Nat. Univ. Caldas [online]. 2023, vol.27, n.1, pp.85-93. Epub 04-Set-2023. ISSN 0123-3068. https://doi.org/10.17151/bccm.2023.27.1.5.
Objetives:
To evaluate the effect of calcium polysulfide on the olfactory response of Trigonospila unicaldasi to odors from citrus plants not attacked and attacked by Compsus viridivittatus.
Scope:
Calcium polysulfide in sublethal doses does not affect the olfactory response of T. unicaldasi.
Methodology:
The sublethal effects of calcium polysulfide on the ability of T. unicaldasi to detect volatiles from citrus plants infested with C. viridivittatus were evaluated through olfactometric experiments.
Main results:
The parasitoid T. unicaldasi can differentiate between odors of unattacked citrus plants and citrus plants attacked by C. viridivittatus and sprayed with calcium polysulfide.
Conclusions:
Calcium polysulfide at a concentration of 1.75% did not interfere with the olfactory response of T. unicaldasi fed on sprayed prey.
