Insecticidal Efficacy of SABRUKA Formulations as Protectants of Cowpea Against Field Pests

Oparaeke A.M., M.C. Dike and C.I. Amatobi
The efficacy of SABRUKA (a mixture of soap, water and kerosene) and its mixture with naphthalene (camphor) was evaluated for the control of insect pests of cowpea during the 1998 and 1999 cropping seasons in the Research Farm of the Institute for Agricultural Research, Samaru, Nigeria. The SABRUKA products were tested against the three major post flowering insect pests of cowpea in the northern Guinea Savanna ecological zone. These pests were Megalurothrips sjostedti Trybom (Thysanoptera: Thripidae) legume flower bud thrips, larvae of Maruca vitrata Fab. (Lepidoptera: Pyralidae), the legume pod borer and Clavigralla tomentosicollis Stal (Hemiptera: Coreidae), the coreid bug. SAMPEA 7, an improved local cowpea variety was used in the study. Four SABRUKA products- camphorated SABRUKA, concentrated SABRUKA, diluted camphorated SABRUKA and diluted SABRUKA. Camphorated SABRUKA and concentrated SABRUKA were effective in reducing the numbers of all the tested pests during the four weekly applications of the products. Pod damage was least on camphorated SABRUKA, consequently leading to higher grain yield compared to other SABRUKA products and the untreated control. From the results, camphorated SABRUKA was recommended for use on farms managed by limited resource farmers in Africa and other third world countries.
