Abstract: | In flight-tunnel assays, mated femaleHeliothis virescens (F.) moths responded by positive anemotaxis to volatiles from extracts of two host plants (cotton and tobacco), but they did not fly to an extract from elderberry (Sambucus simpsonii Rehd.), a nonhost that contains an oviposition deterrent forH. virescens. When the elderberry extract was mixed with extract from either cotton or tobacco, the flight response by moths to volatiles emanating from the extract blends was reduced significantly at most doses when compared to the positive response to extracts from either host alone. The number of landings (including brief contacts) and landings that resulted in oviposition on the substrates treated with extract blends also were reduced significantly in most tests.This article reports the results of research only.
