Abstract:
Present investigations entitled “Varietal preference of mango leaf hoppers and its management through biopesticides” was conducted at the Horticultural mango orchard, B.T.C. College of agriculture and research station, Sarkanda, Bilaspur, Chhattisgarh during November-2020 to May-2021.
Five varieties of mango viz. Langra, Amrapali, Himsagar, Sunderja and Alphonso were tested for biochemical preference to mango leaf hoppers. Overall average minimum moisture percentage was recorded in leaf of varieties Sunderja (49.18%) followed by Himsagar (50.21%) and Langra (51.28%). The maximum moisture percentage was recorded in leaf of varieties Alphonso (53.82%) followed by Amrapali (52.47%).Overall average minimum total chlorophyll was recorded in leaf of varieties Sunderja (2.38 mg) followed by Himsagar (2.51 mg) and Langra (2.61 mg). The maximum total chlorophyll was recorded in leaf of varieties Alphonso (2.91 mg) followed by Amrapali (2.79 mg). Similarly, Overall average minimum chlorophyll-a was recorded in leaf of varieties Sunderja (1.69 mg) followed by Himsagar (1.75 mg) and Langra (1.81 mg). The maximum chlorophyll-a was recorded in leaf of varieties Alphonso (1.94 mg) followed by Amrapali (1.89 mg).and Overall average minimum chlorophyll-b was recorded in leaf of varieties Sunderja (0.69 mg) followed by Himsagar (0.76 mg) and Langra (0.81 mg). The maximum chlorophyll-b was recorded in leaf of varieties Alphonso (0.95 mg) followed by Amrapali (0.90 mg). In case of wax content in leaf average minimum wax content was recorded in leaf of varieties Alphonso (2.42 mg) followed by Amrapali (2.53 mg) and Langra (2.57 mg) and maximum wax content was found in leaf of varieties Sunderja (2.81 mg) followed by Himsagar (2.62 mg).
In correlation with important biochemical parameter, moisture percentage is significantly positive correlated with leaf hopper population with r value 0.945, similaraly Total Chlorophyll, chlorophyll-a and chlorophyll-b had significantly positive correlated with leaf hopper population with r value 0.944, 0.960, 0.952. respectively. Whereas wax content of leaf had significantly negative correlation with leaf hopper population with r value -0.907.
