| dc.description.abstract | Among the entomopathogenic fungal and viral biopesticides tested against H. armigera and S. litura, Metarhizium rileyi (1×108 cfu/g) 1.15% WP found most superior treatment against both the pest. HaNPV @ 500 LE/ha and SlNPV @ 500 LE/ha were also effective treatments against H. armigera and S. litura respectively. As regards seed yield M. rileyi (1×108 cfu/g) 1.15% WP recorded highest seed yield (3.20 q/ha.) with ICBR 1:28.07. Whereas, the treatment with spraying Metarhizium anisopliae (1×108 cfu/g) 1.15% WP found at par with this treatment in respect of yield and recorded (3.12 q/ha) yield of seeds with ICBR 1:26.41. All the tested entomopathogenic fungal sprays, viral sprays and their combinations did not affect the activities of honey bees in the treated field of lucerne seed crop. Study on the pollinator fauna, their relative abundance in lucerne revealed that as many as 12 species of pollinators were foraging on lucerne flowers. Out of these, hymenopterans included eight species forming 83.60 percent of total pollinators. lepidopterans included three species and dipterans included two species which altogether constituted 16.40 percent of total pollinators. The most dominant pollinator was Apis florea (29.60 %) followed by A. cerena (13.60 %), A. dorsata (12.50 %) and A. melifera (8 %) | |
