Soil arthropods recovery rates from 5 - 10 cm depth within 5 months period following dichlorov (an organophosphate) pesticide treatment in designated plots in Benin City, Nigeria
Soil arthropods recovery rate was monitored for five months (April - August) 2007 to ascertain whether the application of dichlorov (an organophosphate) pesticide, in varying concentration levels of 0 L (control), 0.25 L (low) and 0.75 L (high) per 25 m2 would adversely affect the rate of sampling soil arthropods within a 5 - 10cm depth.

Studies on some economic traits and biological characters of regular and reciprocal cross between a multivoltine and bivoltine race of the silkworm Bombyx mori
In order to understand the genetics of cross breeding system between multivoltine and bivoltine race, a hybridization experiment was conducted by crossing females of multivoltine Pure Mysore race (PM) with males of a bivoltine race C108 and its reciprocals. The F1 and F2 progenies of the above crosses were derived in order to study the economic traits and biological characters. The results of...
