Abstract

The red flour beetle (RFB), Tribolium castaneum (Herbst), is a stored-product insect commonly found in rice mills. To understand how RFBs develop on different types of rice fractions occurring in a rice mill, I conducted three studies. I examined egg to adult development on nine rice fractions (rough rice, rice hulls, paddy rice dust, brown rice, rice bran, milled broken kernels, milled whole kernels, milled rice dust and rice flour) and identified brown rice, bran, milled kernels and rice flour were best for development. A second study examined neonate adult development using rice fractions and temperature as variables and found RFB developed best on bran at 32°C. The final study examined the effect of colony origin and rearing media on female oviposition. Wheat flour was the preferred media for oviposition regardless of colony origin. Results of these studies provide information on the RFB’s ability to develop and oviposit on rice milling fractions, which can be useful to rice mill operators when making decisions for Integrated Pest Management (IPM) programs.
