The perilla leaf pyralid moth, Pyrausta panopealis Walker (Lepidoptera: Pyralidae), is a serious pest damaging to leaf perilla. In order to establish the life parameters of P. panopealis for eventual purpose of control, the developmental span of each stage was investigated under five temperature regimes ($20^{circ}C{sim}30^{circ}C$). The larval period of P. panopealis was longest as 26.8 days at $20^{circ}C$ and shortened as temperature goes up to $30^{circ}C$ as 11.3 days. Survivorship of the larval P. panopealis was the highest at $27.5^{circ}C$ as 82.5%, whereas that of other temperatures ranged from 40% ($20^{circ}C$) to 60.0% ($30^{circ}C$), indicating that the P. panopealis appears to favor somewhat higher temperature. In addition to larval period, the duration of egg, prepupal, and pupal period also were shortened sharply as temperature goes up, whereas the duration of adult stage shortened a maximum of only two days as temperature goes up. After the perilla leaf pyralid moths were successfully stabilized in indoor environment the larvicidal efficacy of ten on-the-market environmentfriendly agricultural materials (EFAMs) that were previously selected from the result of other moth species was tested. Seven of the ten tested showed more than 90% of mortality within 12 hrs and reached nearly up to 100% within 24 hrs, but the remaining three showed less than ~70%.
