Seasonal incidence of leafminer (Achrocercops gemoniela Stainton) in relation to weather parameters on sapota

Author(s): Vijayaraghavendra R and K Basavanagoud
Abstract: The Seasonal incidence of Sapota Leafminer Achrocercops gemoniella Stainton (Gracillaridae: Lepidoptera) infesting in relation to weather parameters was carried out on sapota varieties viz., Kalipatti, DHS-1, DHS-2 and Cricket ball at new orchard College of Agriculture, Dharwad and DHS-2 variety at KVK, Sadapur Farm, Dharwad, Karnataka, India during 2013 June–2014 May. Infestation of leaf miner was appeared more or less throughout the year except April and Maywith peak period of infestation 3.02 % in October and lowest of 0.30 % in March. Maximum incidence (1.60%) in Cricket ball and it was lowest (1.13%) in DHS-1 whereas the pest incidence on other two genotypes varied from 1.39 to 1.53%. Leaf miner incidence had significantly positive correlation with morning, evening relative humidity and rainfall in all the four genotypes. Whereas, maximum and minimum temperature had significantly negative correlation with pest incidence.
