Effect of Different Growing Environments of Pigeonpea Cultivars on Population Dynamics of Clavigralla gibbosa and its Relationship with Microclimate

The field experiment was carried out at research farm of Department Agricultural Meteorology, Chaudhary Charan Singh Haryana University, Hisar, during Kharif season 2017-18 to study the influence different growing environments on Clavigralla gibbosa population dynamics and its relationship with microclimate pigeonpea cultivars. results revealed that egg masses adult C. were first recorded 38th SMW continued until crop harvesting in all cultivars D1 (First fortnight May), D2 June) sown crops, whereas it observed 40th 39th D3 (Second crop, respectively. Mean number (0.15 masses/plant) adults (1.24 adults/plant) highest under whereas, among cultivars, found higher (1.18 cultivar Paras. nymphal initially noticed Manak D2, while, Paras UPAS-120, SMW.
