Toxicity and repellency of semiochemicals extracted from a dolichoderine ant (Hymenoptera: Formicidae) to the Formosan subterranean termite (Isoptera: Rhinotermitidae)
Environmental Entomology 24 (5), 1263-1269
Abstract: The anal gland secretions of ants in the subfamily Dolichoderinae contain terpenoids that are known to have insecticidal properties. The repellency and toxicity of whole-body extracts and chemical fractions of such extracts from the dolichoderine ant Ochetellus glaber (Mayr) to Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae) were examined. Extract-treated sand caused significant termite mortality in a direct-exposure assay. Termites were also repelled by extract-treated sand and the chemical repellency lasted for at least one month in treated sand. The principal repellent components of O. glaber secretions were determined to be cis,trans-and trans,cis-isomers of dolichodial in a 3:1 ratio.
