| dc.description.abstract | The leaf infestation pattern as well as population dynamics of five different foliage feeders (Idioscopus clypealis Linnaeus, Drosicha mangiferae Stebbing, Apsylla cistellata Buckton, Popillia japonica Newman, Myllocerus discolour Boheman) was observed in mango crop at Horticulture Research Centre Pattharchatta during 2012 and 2013. The incidence of all insect pests occurred once in a year. The incidence of all the pests was maximum in East direction and minimum incidence was recorded in North direction. The population as well as leaf infestation was significantly different in both the orchards. The abiotic factors (Temperature and Relative humidity) had significant impact on pest incidence. Rainfall was a limiting factor for all the insect pests. The relative abundance of different insect pollinators during the flowering season was found to be maximum in the 4th week of March in East direction. The maximum abundance of Syrphids (3.8 and 4.3 foragers/inflorescence/3min), Musca domestica (3.0 and 1.1 foragers/inflorescence/3min), Coccinella septempunctata (3.7 and 2.3 foragers/inflorescence/3min) and Trigona laeviceps (1.8 and 1.7 foragers/inflorescence/3min) was recorded at 1100 hours during the year 2012 and 2013 respectively. The surrounding environment of inflorescence had more impact on the relative abundance of pollinators than the open environment of location. | en_US |
