Abstract
Oil soluble dyes, Congo Red and Sudan Red 7B were evaluated as markers for mass reared Asian cornborer (ACB). Aliquot of the oil soluble dye was added to the IPB Modified CIMMYT artificial diet and was fed to F1 ACB neonates wherein growth and development were monitored. The Congo Red was tested at 100, 250, 400 and 600 ppm concentrations, while Sudan Red 7B was tested at 600, 700 and 800 ppm. Based on the results of the test using Congo Red, there were no markings on the egg masses laid by the marked adults. It was also found out that Congo Red dye had an adverse effect to pupal weight and it also exhibited poor marking ability on pupae. Test results using the Sudan Red 7B dye on 600 and 700 ppm concentrations showed no adverse effects on the larval and the pupal development. In addition, Sudan Red 7B was able to mark ACB pupae including egg masses laid by the marked adults. Without altering the duration of the development, 700 ppm Sudan Red 7B was used effectively as marker for mass-reared ACB with enhanced effect on the pupal weight, the larval length, and the larval width. In conclusion, the use of Sudan Red 7B that successfully marked pupae can be used for field studies on adult dispersal and behavior.
