Abstract

Population buildup of pear psylla (Cacopsylla pyricola) Foerster on pear was studied under temperate conditions of Kashmir valley during 2014–2015. The population was correlated with maximum and minimum temperature (°C), morning and evening relative humidity (%), and rainfall (mm). The results revealed that the population of nymphs and adults was observed till harvest (1st week of September) with three peaks during June and July (23rd, 27th and 29th standard week). The maximum population was observed during June i.e. 12.57/12 shoots.
