Section VIIFoliage & Seed InsectsPOTENTIAL OF SPINOSAD FOR CONTROLLINGCOLORADO POTATO BEETLEG. Xu and G. E. LongDepartment of EntomologyWashington State UniversityPullman, WA 99164-6382509/335/5504Spinosad (proposed common name) was recently discovered and developedby scientists at DowElanco. Spinosad is a mixture of two spinosyn factors called A andD. Spinosyns are naturally derived metabolites from a new species of Actinomycetesbacterium, Saccharopolvspora spinosa. which demonstrate potential in insect control.Field trials of Spinosad were conducted in 1995 at the Washington StateUniversity Othello Research Station, Othello, Washington. The effects of Spinosad onthe Colorado potato beetle, Leptinotarsa decemlineata (Say), and beneficialorganisms were evaluated. Results demonstrated that Spinosad provided excellentcontrol of beetle larvae under field conditions. This compound appeared to be inactiveon major predators and parasitoids on potato foliage. As a new bioinsecticide,Spinosad has high potential for integrated management practices for the beetle.92
