DISTRIBUTION STATEMENT (of this Report)Approved for public release; distribution unlimited. The acute toxicity of JP-4, JP-8 and JP-9 fuels was evaluated for several terrestrial insects by contact exposure. JP-8 was the most toxic fuel to most of the insect species. Shale derived fuels were more toxic than their petroleum derived counterparts, however, species response varied with each type fuel. The order of decreasing susceptibility to petroleum derived JP-4 was earwigsrice weevilsbflour bettles, lady beetles'ptenebrionid beetlegcockroaches.
