Abstract
Surveys conducted on importance of soil pests on groundnut production indicated that the majority of farmers were aware of damage caused by soil pests to groundnut, Bakura, Mamudo, Sada, Ngurore, Girei and Gusau are areas where soil pests cause great damage to groundnut. Experiments conducted elsewhere indicated that millipedes were found to be causing damage at germination and from the 5th to 7th week after planting. Termites on the other hand caused greater damage at crop maturity. Biological studies were conducted to raise colonies of Macrotermef subhyalinus (Rambur) - (a minor pest of groundnut in the Guinea Savanna) in the laboratory. Two methods were successfully adopted, namely; the aluminium foil method and the glass plate method. Observations were made on colony development, brood development, foraging and fungus-comb establishment. This is a significant achievement not only for the purposes of obtaining further information on the biology, feeding habits and food preferences of termites in the laboratory but also for the bioassay of candidate insecticides for subsequent control measures in the field. From the field trials it was found that carbofuran (Furadan 3G) did not give significant control of soil pests of groundnuts.
