Seasonal incidence of leaf miner Chromatomyia horticola (Goureau) infesting pea

MG Raut, BA Bade and VM Rajenimbalkar
The present investigations entitled seasonal incidence of leaf miner, (Chromatomyia horticola Goureau) infesting pea (Pisum Sativum L.) was carried out at experimental farm of Agricultural Entomology Section, College of Agriculture, Pune under Mahatma Phule Krishi Vidvapeeth, Rahuri during Rabi-2020-2021. In order to know the effect of weather parameters on incidence of leaf miner on pea, the study was carried out during Rabi 2020-2021. The leaf infestation (%) by leaf miner was recorded during different meteorological weeks on “Bonneville” variety of field pea. The meteorological data were collected from meteorological observatory at College of Agriculture, Pune. The data on leaf miner infestation was correlated with weather parameters to determine the relationship with the pest. The incidence of C. horticola on pea commenced from 3rd week of December i.e. 51th SMW with an average infestation of 4.12 per cent per plant. The leaf miner infestation is gradually increased and reached its peak level i.e. 47.17 per cent during 3rd week of February (8th SMW). Studies on correlation of pea leaf miner infestation with weather parameters revealed that the pea leaf miner infestation exhibited significant, positive correlation with maximum (r=0.639) and non-significant negative correlation with minimum temperature (r= -0.151) non-significant positive correlation with morning relative humidity (r=0.036) and non-significant negative correlation with evening relative humidity (r= -0.471) wind velocity and sunshine hours showed non-significant positive correlation (=0.193) and (r = 0.374) respectively. However rainfall showed non-significant negative correlation (r = -0.102).
