Lure Placement:
Do not include lures for other target species in the trap when trapping for this target.
Lure Notes:
Place S. litura and S. littoralis lures in different traps and separate at least 20 meters (65 feet).
Though the lures for Spodoptera littoralis and S. litura are composed of the same two compounds (Z,E,9,11-14:AC and Z,E,9,12-14:AC), the compounds are loaded into the lure dispensers in different amounts depending on the target species. Therefore, it is necessary to use the specific lure for each of the two targets.
Identification
ID/Diagnostic: Morphological
Morphological: Difficult to distinguish from S. littoralis without close examination of the genitalia; consult appropriate keys by Todd and Poole (1980) and Pogue (2002). To separate from other noctuids, use the key developed by Todd and Poole (1980).
Mistaken Identities:
Present in U.S.: Spodoptera dolichos, S. ornithogalli, S. pulchella, and S. latifascia.
Not present in U.S.: Spodoptera littoralis
