Abstract
Different colour papers have been shown to attrat the first and third instar larvae of Chilo partellus in different degrees. Green bice (No. 329) and light green (No. 323) elicited maximum larval attraction; followed by foliage green (No. 328) and cadmium yellow (No. 307). The green bice paper has been found to be much more effective than foliage green or cadmium yellow aper as a cylindrical sticky trap for the larvae. Even when competing with the host plant, sorghum, these colour paper traps proved more effective than the plants for attracting and trapping the larvae.
