Impact of biochemical constituents of host plants on the rugose spiraling whitefly, Aleurodicus rugioperculatus martin infestation levelsinandhra pradesh.


The rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus Martin is an invasive pest of polyphagous in nature and attacks a wide range of host plants. RSW has become a consequential pest and identified in the several regions of India, including Godavari districts of Andhra Pradesh. Since, it is a new species, lack of information necessitated immediate attention of scientific community to focus on detailed studies of the pest. In this scenario, a study has been conducted to know the impact of biochemical constituents of host plants in relation to RSW infestation. Results revealed that, a lower level of total phenol content resulted highest RSW infestation in oil palm in which other constituents viz moisture, chlorophyll, proteins and total sugars were in higher levels among the host plants studied, coconut, guava, banana and cocoa. Lowest RSW infestation was observed in cocoa leaves in which higher level of total phenols and lower levels of moisture, chlorophyll, proteins and total sugars were recorded. The correlation coefficients of RSW infestation were strong and negative with total phenols whereas positive and significant with respect to moisture, chlorophyll, proteins, total sugars; non significant with fiber and lignin.
