Comparison to yields from insecticide-treated and untreated sugarcane variety plots in 14 experiments conducted from 1959 to 1965 show a wide range in varietal response to damage by the sugarcane borer, Diatraea saccharalis (F.). Yield losses from sugarcane borer damage were much greater for varieties C.P. 48-103 and C.P. 44-101 than for varieties NCO 310, C.P. 36-105, and C.P. 52-68. These data indicate that annual savings of as much as $50.00 per acre may be realized when sugarcane growers utilize borer-resistant varieties. Criteria previously used for selecting sugarcane borer-resistant varieties were found to be inadequate for detecting actual yield losses among varieties.
