Seasonal Incidence of Pea Leaf Miner Chromatomyia horticola Goureau Infesting Garden Pea

The seasonal incidence of pea leaf miner Chromatomyia horticola Goureau, on garden pea (Pisum sativum L.) was assessed during 2017 and 2018 at the research farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Chatha. The pooled data revealed that the incidence show continuous fluctuation, with first appearance being during the 49^th standard meteorological week (SMW)- 0.95 miners/ leaf which reached its peak (11.00 miners/ leaf) during the 4^th SMW, then reached to minimum (1.26 miners/ leaf) during the 12^th SMW. The correlation studies indicated highly significant negative association between incidence and maximum temperature (-0.714**), significant positive one with evening relative humidity (RH) (0.544*); and non-significant ones with minimum temperature (-0.385) and wind speed (-0.74), morning RH (0.258), sunshine (0.013) and rainfall (0.356).
