Responses of parasitoids to volatiles induced by Chilo partellus oviposition on teosinte, a wild ancestor of maize.

abstract：:Red imported fire ants, Solenopsis invicta Buren, build nests by excavating soil. Incorporation of ant-derived chemicals in nesting material has long been known; however, only a few chemicals have been identified. This paucity of identified ant-derived chemicals may be due to the interference from soil-borne compounds...
