Abstract:

Population growth curves of Tribojium castaneum for various media at 26 , 1°C and 60—70% R.!?. showed a decline tn the adult populations during the first four months of rearing for the media containing fenugreek seed flour. After this period this effect was not evident because of the influences-of ecological factors affecting the popula tions such as food shortage and overcrowding effect. Mortality data revealed that the addition of fenugreek seed flour did not increase the adult mortalities for T. castaneum and Sitophilus oryae during the first five months ز7 rearing under the eriimental conditions. The rate of growth for T. castaneum was found markedly higher than that of S. ory3ae. In contrast to the results achieved forthe popuLation growth curves of T. castaneum, the fenugreek addition to the diet of S. oryae induced higher adult populations during the first eight months of rearing; when compared with the untreated media. After this period the populations decreased to tower levels in the different diets.
