A Note on the Effect of Aqueous Filtrates of Argel Plant Parts (Solenostemma argel, Del Hyne) on the Mortality of Cotton Soil Termite (Microtermes thoracalis Sjost.) (Isoptera: Termitidae)

Abstract

A laboratory experiment was carried out to evaluate the efficacy of three
concentrations (5 %, 7.5 % and 10 %) of aqueous filtrate of argel (Solenostemma argel)
against workers and soldiers of the cotton soil termite (Microtermes thoracalis). The
synthetic insecticide Morisban 4 was used as a standard. Statistical analysis showed
significant differences between the tested concentrations of argel aqueous filtrates and
Morisban 4 compared with the untreated control. The highest concentration (10%) of
argel aqueous filtrates and Morisban 4 gave 100% mortality for termites. The study
proved the suitability of argel parts for controlling termites, and represents a good
environmental and alternative method for synthetic insecticides of termites.
