Other claims from this paper (13)
- Observation M. obtusa larvae first appeared in the 41st meteorological standard week.
- Observation M. obtusa pupae first appeared in the 39th meteorological standard week.
- Observation Peak larval populations were 52.00 and 41.00 larvae per 100 pods in the 44th MSW in the respective years.
- Observation Peak pupal populations were 49.00 and 40.00 pupae per 100 pods in the 50th and 45th MSW.
- Observation Euderus lividus was found parasitizing the pigeon pea pod fly.
- Observation Ormyrus orientalis was found parasitizing the pigeon pea pod fly.
- Observation E. lividus parasitism declined from 31.82 to 10.53 per cent from the 46th to 52nd MSW.
- Observation E. lividus parasitism declined from 29.72 to 7.14 per cent from the 45th to 50th MSW.
- Observation O. orientalis pupal parasitism was high at 24.32% in the 44th MSW.
- Observation O. orientalis pupal parasitism was low at 3.22% in the 1st MSW.
- Observation O. orientalis pupal parasitism was low at 3.84% in the 51st MSW.
- Association Pod fly larval population had a significant positive association with maximum temperature in both years (r=0.646 and r=0.746).
- Recommendation The authors suggest E. lividus and O. orientalis could improve biological control of M. obtuse.
