An in vitro study was conducted to evaluate the optimum roughage to concentrate ratio in complete rations using unconventional sweet sorghum bagasse (SSB), a by product of ethanol industry as sole roughage source. Eight rations were prepared with roughage to concentrate ratio of 100:0 to 30:70. S...

The aleyrodid Aleurodicus dispersus is reported from Nigeria. The first observation was made on cassava in early 1992 at several locations in Ibadan. A survey carried out in January 1993 revealed that several genera, many of them important food and ornamental crops, are food plants of the insect.

Few studies have addressed the relationship between genetic diversity and provision of ecosystem services in agroecosystems. In this review, we argue that the contribution of biological diversity to ecosystem functioning in agricultural production systems is variable, but can be substantial, and ...
