Spinosad is a biopesticide, derived from fermentation by the soil-dwelling actinomycete, Saccharopolyspora spinosa, which is used to control a variety of insects. Spinosad kills a wide range of insect pests when ingested or topically applied, by overexciting the nervous system, yet is harmless to mammals and many predatory insects. Other modes of action of this insecticide have not been documented. Here, we report that a non-lethal dose of spinosad causes adult male and female German cockroach, Blattella germanica, to exhibit altered responses to their aggregation pheromone as well as to have a changed cuticular hydrocarbon profile.
