Abstract:
Under present studies, hoppers, thrips and fruit fly among the insects and anthracnose and powdery mildew among the diseases had caused both qualitative and quantitative losses in fruit yield during both the years. Activity of different species of hoppers (Amritodus atkinsoni, I. clypaelis, I. niveosparsus) and thrips (Rhiphiphorothrips cruentatusScirtothrips dorsalis, S. mangiferae), persisted throughout the year on different parts of the mango tree while of fruit fly (Bactrocera dorsalis, B. zonatus, B. correctus) from March to July. Hopper population observed significant positive correlation with maximum temperature (‘r’ = 0.3716) and sun shine hours (‘r’ = 0.4364) and significant negative relationship with minimum temperature (‘r’= -0.3964), morning relative humidity (‘r’ = -0.2762), evening relative humidity (r= -0.4825), average relative humidity (r= -0.4708), rainfall (r= -0.2957) and rainfall days (r= -0.4009). R value was however non- significant. Number of hoppers, thrips and per cent fruit damage by fruit fly and intensity of powdery mildew and Anthracnose was reduced as a result of implementation of different components of IPM technology as compared to farmer’s practice where scheduled application of 15-20 sprays was made during both the years. Adoption of IPM module resulted in reduction in number of application of highly toxic pesticides (6) as compared to farmer’s practice (11-12 sprays) thus cutting the cost of plant protection and more economic returns during both the years under studies.
