Field Evaluation of Certain Chemicals and Biopesticides against Pod Borer, Helicoverpa armigera (Hubner) in Chickpea: An Experimental Research| Chapter 5 | Research Highlights in Agricultural Sciences Vol. 6

 The basic goal concerning this study search out learn about the belongings of chemicals and biopesticides on H.armigera control. An experiment was completed activity at the research plot of the Department of Agricultural Entomology at Central Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj all the while the rabi season of 2021. With seven treatments and individual controls plot, the field was laid out in a randomised block design (RBD). The mean fundamental population plant was calculated the era before, three, seven, and fourteen days after each spray. When distinguished to the control, all of the pesticides tested considerably diminished pest scourge. Based on pest culture, seed yield, and B: C ratio, the following results were acquired: T4 Spinosad 45% SC is the most active treatment against grandam pod drill of Mean larvae population bearing maximum yield and recording excellent Cost-Benefit percentage compared to additional treatments. When the cost-benefit percentage was determined, an interesting result was acquired.  The best and most cost-effective situation among those proven was Spinosad 45% SC (1:3.98), Spinetoram 11.7 SC (1:3.95), understood by Chlorantraniliprole 18.5% SC (1:3.82), Flubendamide 39.35% SC (1:3.73), Bacillus thuringiensis 1x108 CFU/ml (1:3.21), and Beauveria bassiana 1x108 CFU/ml (1:2.96), The lowest cost benefit ratio was written in Metarhizium anisopilae 1x108 CFU/ml (1:2.80) when compared to Control (1:1.95).

Forecasting of Losses Due to Pod Borer, Pod Fly and Yield of Pigeonpea (Cajanus cajan) for Central Zone (CZ) of India by Using Artificial Neural Network | Chapter 08 | Current Topics in Agricultural Sciences Vol. 5

 Pigeonpea (Cajanus cajan L.) is a valuable food legume that may be cultivated with minimal inputs under rainfed conditions. Starch, protein, calcium, manganese, crude fibre, fat, trace elements, and minerals abound in pigeonpea. The need of having a timely forecast of productivity and pod damage caused by key insect-pests in pigeonpea has become a serious issue due to high domestic consumption and large losses due to major insect-pests. The built Artificial Neural Network (ANN) model for forecasting productivity (Kg/ha.) and percent pod damage by two important insect-pests, Helicoverpa armigera and Melanagromyza obtusa, of medium ripening pigeonpea in the Central Zone (CZ) of India, is reported in this paper. The model's performance was evaluated using mean squared error values, and it was determined to be suitable for the task at hand.

Plant Bio-chemicals against Helicoverpa armigera (Hübner): A Study in Tomato |Chapter 11 | Cutting-edge Research in Agricultural Sciences Vol. 10

 The mechanism of host plant resistance in tomato varieties was evaluated and compared to the attack of the tomato fruit borer, Helicoverpa armigera (Hubner), in the Solan district, known as the “Tomato Bowl of Himachal Pradesh.” Understanding the mechanisms of induced resistance allows us to predict which pests will be affected by induced responses. Induced response elicitors can be sprayed on crop plants to strengthen the natural defense system against herbivore damage. Three self pollinating indeterminate varieties developed by selection (Solan Lalima, Solan Vajar, and Palam Pink) and four hybrids (Naveen 2000+, Heem Sohna, and Palam Pink) were used in the experiment. Researchers extracted various macro and micronutrients from the foliage of these varieties, as well as estimating the chemical composition of tomato fruits, such as total phenols, titrable acidity, reducing sugars, and total sugars, to compare for different levels of resistance to Helicoverpa armigera. Fruit infestation was found to be inversely related to phenol and sugar content in tomato fruits, as measured by correlation coefficient values (r= -0.895) and (r= -0.650), respectively, indicating that less susceptible varieties were high in phenols and sugars, protecting them from pest attack. Nitrogen (r= 0.660), potassium (r=0.679), magnesium (r=0.698), and iron (r= 0.547) are all related. Phosphorus (r= -0.857) and zinc (r= -0.801) content were found to be positively correlated with percent fruit infestation, whereas manganese (r=0.546) content was found to be negatively correlated with percent fruit infestation. This resistance can be used to create crop cultivars that rapidly produce the inducible response in the face of a mild infestation, and it can be used as an important component of integrated pest management alongside other techniques such as biological, cultural, and chemical control.

Investigation of Avoidable Losses Due to Effect of Pod Borer, Helicoverpa armigera (Hubner) in Chickpea | Chapter 8 | Cutting-edge Research in Agricultural Sciences Vol. 3

 The purpose of this study is to quantify losses due to the major chickpea pest. Borer pod, Armigera helicoverpa. Chickpea is one of the most important crops for pulses. Considering the financial value Protective measures for this crop need to be taken well in advance to avoid damage to the pod due to Borer pod. During the 2009-10 rabi season, an experiment was performed at the Experimental Area of The Entomology Department, Live Stock Farm, Adhartal, JNKVV, Jabalpur (M.P.), India. This research adopted similar dimensions in two care and untreated plots. For the analysis, the Chickpea variety, JG-130, was selected and planted. During sowing, all of the prescribed package of practises were followed.  The findings have shown that the Pod borer is a notorious chickpea pest found in Jabalpur, Madhya. Pradesh and avoidable losses were estimated at 63.64 percent due to this chickpea pest. The Gram pod borer has been  The key chickpea pest, which significantly reduced the yield, was found to be…
