BSS249 : Preparedness for borer incursion : Summary of effectiveness of Tebufenozide for control of sugarcane stemborers
Following a search of the literature and discussions with entomologists in Papua New Guinea and Louisiana, tebufenozide (Mimic?, Confirm? or RH-5992) was identified as a potential highly useful candidate insecticide for emergency use in Australia following an incursion of a stemborer.Tebufenozide is an ecdysone agonist that acts by binding to the ecdysone receptor protein. The moulting process of treated insects is lethally accelerated. It is non-phytotoxic and shows little negative effect on populations of stemborer parasites and other beneficial insects. It is registered for use in USA against Diatraea saccharalis and is used successfully in Papua New Guinea against Sesamia grisescens.Data included in this report demonstrate the effectiveness of tebufenozide against these two stemborer species and its minimal effects on beneficials. Data are also included on the chemical composition of the compound, its physico-chemical properties, toxicology and environmental fate.
