| Abstract: | Acid fuchsin staining is widely used as a method for easy detection of egg plugs deposited by Sitophilus spp. The effect of increasing grain moisture content through staining on some life history characters of three geographical strains of Sitophilus oryzae was examined. The results show that staining increases development rate and survival from egg to adult and there is also a suggestion of a strain × treatment interaction. Factors requiring consideration if staining is carried out are discussed. |
