Abstract:
Studies were carried out to assess the influence of biochemical constituents of oil palm on the incidence of invasive whitefly species, Rugose spiralling whitefly, Aleurodicus rugioperculatus Martin and Bondar’s nesting whitefly, Paraleyrodes bondari Peracchi. The biochemical characters viz., moisture content (%), total protein content (g/100g), total sugars(%), reducing sugars(%), total phenol (mg/g), fibre content (%), chlorophyll content (SPAD Units) and tannin (mg/g) were studied. It was observed that among all the biochemical constituents moisture (r= 0.929), proteins (r= 0.947), total sugars (r= 0.938), reducing sugars (r= 0.934) and chlorophyll content (r= 0.938) exhibited significant positive correlation with pest intensity and whereas phenols (r= -0.934) and tannins (r= -0.848) showed negative correlation with pest intensity and fibre content (r= -0.053) showed no significant correlation with pest intensity.
