Banana rust thrips, Chaetanaphothrips signipennis (Bagnall) are important pests of bananas in north Queenland. One application of chlorpyrifos, pirimiphos-ethyl and prothiophos to the butt and surrounding soil and one application of ethoprofos to the soil surrounding the butt of banana plants each reduced the incidence of the pest and subsequent damage. Dieldrin as a treatment to the butt and surrounding soil was not effective and thrips numbers and damage were significantly higher on treated than on untreated plants. Diazinon treatments to bunches did not significantly reduce the level of fruit damage when compared to the butt-soil organo phosphate treatments but these bunches consistently had lower thrips numbers and fruit damage
