Evaluation of diatomaceaous earth, methoprene, and varietal resistance to control the Lesser Grain Borer in stored rice

Research

Diatomaceous earth (DE) and methoprene, two insecticides with low mammalian toxicity, will be evaluated against the lesser grain borer, Rhyzopertha dominica (F.) on rough rice (Oryza sativa L.). Since DE or methoprene alone may not completely control lesser grain borers, a combination approach may be required to give effective protection. Long grain, medium grain, and short grain rough rice will be tested for varietal resistance to the lesser grain borer, and resistance characters will be measured by assessing development effects. Varietal resistance will be integrated with the chemical treatments to employ a combination approach to control the lesser grain borer on rough rice.
