摘要

The aim of this Study was to determine the effect of Larger Grain Borer {Prostephanus truncatus Horn) on stored paddy rice. The study was conducted at Sokoine University of Agriculture, Department of Crop Science and Production Laboratory from November, 2005 to March, 2006. Rice varieties TXD 85, TXD 88, TXD 220 and TXD 306 were used. The experimental design was Complete Randomized Design (CRD) with four replications. Ten live P. truncatus were introduced into bottles containing 3000 seeds of paddy rice and allowed to feed. Data collected were number of live insects, damaged and undamaged seeds, percentage damage, weight loss and germination rates of infested seeds. Results showed that there was a significant (p<0.05) difference in number of live P.truncatus among paddy rice varieties at the end of storage time. Varieties TXD 85 and TXD 88 had fewer live P. truncatus than TXD 220 and TXD 306. However, results show that rice varieties did not differ significantly (p>0.05) weight loss. Significant (p<0.05) effect of P. truncatus on percentage germination rate of paddy rice seeds was observed. The infested paddy rice seeds showed low germination rates compared to uninfested seeds. Infested variety of TXD 306 had relatively lowest germination rate compared to other infested varieties indicating relatively resistant to a pest.
