| Summary, etc | Tomato (Lycopersicon esculentum Mill.), belonging to the Solanaceae family is one of the most important vegetable crops. There are certain factors that plague its productivity and overall output, the most important being insect pest attacks. Therefore, the present study was undertaken with the objectives of studying the insect diversity in tomato ecosystem and evaluating the efficacy of various bio-pesticides for the management of borer complex of tomato. The experiment to study diversity of insects was conducted at Experimental Field, CPGS-AS, Umiam for two cropping seasons viz., October, 2022 - January, 2023 and February, 2023 - May, 2023. The tomato variety Pusa Ruby was transplanted in ten plots with each plot having 12 plants. A total of 29 insect species were recorded which belonged to 7 orders and 22 families, the most abundant order being Coleoptera with 9 species followed by Hemiptera (6), Diptera(5), Lepidoptera (3), Hymenoptera (3), Odonata (2) and Orthoptera (1). A total of 19615 nos. of insect pests, 411 nos. of natural enemies and 56 nos. of pollinators were recorded during October, 2022- May, 2023. During winter and spring-summer, Simpson’s indices were 0.283 and 0.271, and Shannon indices were 1.398 and 1.447, respectively. 15 insect species were identified to be insect pests of tomato, while 10 species as natural enemies of pests of tomato and 4 species as pollinators. Aphis gossypii Glover was the most abundant insect pest with a relative abundance of 42.51 %, followed by Tuta absoluta Meyrick (25.48 %) and Helicoverpa armigera Hubner (20.74 %). Nesidiocoris tenuis (31.75 %) and Allograpta obliqua (42.86 %) were the dominating natural enemy and pollinator of tomato, respectively. Aphis gossypii attained a peak population (38.4 adults/3 leaves) at 48th SMW i.e., 4th week of November, whereas, Helicoverpa armigera reached peak population (7.1 larvae/plant) at 49th SMW i.e., 1st week of December and Tuta absoluta (7.3 larvae/plant) at 47th SMW i.e., 3rd week of November. The incidence of the major insect pests had a significant positive correlation with maximum temperature and a negative correlation with relative humidity. To evaluate the efficacy of biopesticides for the management of borer complex of tomato, the experiment was laid in Randomised Block Design with 7 treatments and 3 replications during March, 2023 – June, 2023. The treatments included Bacillus thuringiensis, Spinosad 45 % SC, Spinatoram 11.7 % SC, Azadirachtin 0.03 %, Consortium of Beauvaria bassiana, Metarhizium robertsii (M. anisopliae),Trichoderma harzianum, Lecanicillium lecanii (Verticillium lecanii), Pseudomonas fluorescens and Chlorantraniliprole 18.5 % SC. All the treatments were significant over control in reducing percent fruit damage. Chlorantraniliprole 18.5 % SC was found to be the most effective in controlling borers with a percent reduction of 72.38 over control, followed by Spinosad 45 % SC with a percent reduction of 77.64 and both are statistically at par with each other. Maximum yield was obtained from plots treated with Chlorantraniliprole 18.5 % SC (12.5 t/ha), followed by Spinosad 45 % SC (11.8 t/ha). The highest B:C ratio was also obtained from Chlorantraniliprole 18.5 % SC (3.05:1), tailed by Spinosad 45 % SC (2.42:1). |
