dc.description.abstractThe present investigation entitled “Biology and eco – friendly management of tomato fruit borer Helicoverpa armigera Hubner., (Lepidoptera:Noctuidae) in low hills of Himachal Pradesh” were carried out in the College of Horticulture and Forestry, Neri (Hamirpur), Himachal Pradesh. Experiments were conducted to understand and collect data on biology and eco friendly management of tomato fruit borer using different insecticides and bio - pesticides. The study of the biology revealed that there were six larval instars incase of tomato fruit borer having total larval period of 17- 25 days. Cannibalism was seen from 2nd instar. Males were observed as being greenish grey in colour, while females were described as being light brown with tuft of hairs on the tip of abdomen. Out of the six insecticides and bio-pesticides which were evaluated against tomato fruit borer, spinosad 45 EC were proved best against tomato fruit borer with lowest mean larval count 3.29. Maximum larval count was seen in the agni astra treatment 13.75. Maximum mean yield was seen in spinosad 24.94 kg/plot. All the treatments proved significantly superior to the control.
