摘要: The sugarcane borer, Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae), is a major agronomic pest in the southeastern USA. This study was conducted to investigate performance of D. saccharalis on eight rice cultivars widely grown Louisiana and assess relationship between oviposition preference offspring performance. In previous study, borers found vary same cultivars. this variation larval observed. overall larvae terms relative growth rate boring success highest Priscilla Cocodrie. Larval lower hybrid XL723, Clearfield (herbicide-resistant) variety CL161, medium grain Bengal. Also, took more time enter into stem XL723 compared with Significant positive correlations were observed among preference. measures suggest operation common resistance mechanism. Results laboratory greenhouse extended field, where Cocodrie Cheniere most damaged cultivars, whereas CL161 Jupiter least injured average number borer entry/exit holes per plant. from could contribute use resistant an integrated management program for identified be used as sources breeding programs against borers.
