A field study was conducted to evaluate the efficacy of five insecticides viz., Lambdacyhalothrin 5 EC, Novaluron 10 EC, Clothianidin 50 WDG, Indoxacarb 14.5 SC and Quinalphos 25 EC (standard check) against gram pod borer (Helicoverpa armigera H.) on chickpea (Cicer arietinum L.) variety Pratap Channa-1. Lambdacyhalothrin 5 EC gave the highest reduction in the larval population of pod borer and was found statically at par with Indoxacarb 14.5 SC. The next effective treatments were Clothianidin 50 WDG and Quinalphos 25 EC, However, Novaluron 10 EC @ 750ml/ha proved to be the least effective treatment as it resulted in lowest per cent reduction in the larval population. Highest cost benefit ratio of 1:2.10 was obtained from Lambdacyhalothrin 5 EC followed by Indoxacarb 14.5 SC (1: 1.65). The next cost effective treatment in terms of CBR was Quinalphos 25 EC (1:1.64), whereas, Novaluron 10 EC (1:1.15) and Clothianidin 50 WDG @ 500g/ha (1:0.66) could not show any conspicuous gain over cost.

A field experiment on evaluation of biopesticides against gram pod borer (Helicoverpa armigera Hub.) on pigeon pea was carried out during kharif season of 2012-13. The experiment was laid out in randomized block design with three replications. Gram pod borer is a major pest of pigeon pea in India. For the management of this pest seven biopesticides were tested along with control. Among the biopesticides, Beauveria bassiana @ 1 liter / ha (1x1012 spores/ml) was found to be most effective biopesticide as it recorded lowest larval population (6.68 larvae / 5plants). The highest larval population was recorded in control (12.61 larvae /5 plants). The least effective treatment was Paecilomyces fumosoreseus (9.31 larvae /5 plants). Similar trend was observed in the grain yield as 1667.55 kg/ha, 709.41kg/ha and 1025.21kg/ha , respectively.

To determine Incremental Cost-Benefit Ratio (ICBR) of certain bio-pesticides and insecticide against 2nd larval instar of Helicoverpa armigera in chickpea, an experiment was conducted during winter 2011. Certain pesticides as sole treatments were tested with standard, low and high doses and in treatment combinations with one half of standard doses of two respective pesticides only once at 50% flowering and podding stage of the crop. Upon crop maturity; total grain yield, additional yield, increased income and net income were obtained for each respective treatment to determine its ICBR. Overall, the treatment combination of ½ Btk + ½ Azadirachtin had the highest ICBR of 1:27.57. The lowest ICBR of 1:5.25 was obtained with Azadirachtin-0.05 %, when other treatments had ICBR from 1:8.51 to 1:23.28.

Helicoverpa Armigera Hubner

Weekly larval populations of pod borer, Helicoverpa armigera (Hubner) collected from 20 districts of Maharashtra under Crop Pest Surveillance and Advisory Project (CROPSAP) during 2010-2015 were analyzed to work out the effect of weather variables on the incidence of this insect on soybean. The appearance of larva was observed throughout the soybean growing season, and the peak incidence was observed during third week of August to first week of September (34-35 SMW). The correlation analysis of the data revealed that larval population was significantly and positively influenced by the minimum temperature and rainfall of current week as well as previous two weeks. For the development of forewarning model, data for the period from 2010 to 2013 were used as training dataset and two year (2014-2015) data as validation dataset. The mean model used for forewarning the incidence of pod borer larval population was developed by using step-wise multiple regression analysis in polynomial form. The results of mean model revealed that the significant variables affecting the pod borer larval population in soybean were maximum temperature (current and 1st lag week), and rainfall (current week) and the model explained 48.93% variation. The pre-disposing conditions for the incidence of larvae have been worked out as maximum temperature ranging from 26.1 to 31.47 ºC and rainfall ranging from 6.63 to 141.46 mm with low or medium rainfall in previous weeks followed by high in current week. The model was validated with 2014-15 independent dataset with predicted R2 (R2 ) value 28.13%. Two sample t-test showed no Pred significant difference between observed and predicted values (p = 0.3691 > 0.05).

An experiment was conducted for the year 2016-17 to compare the efficacy of neem bio-pesticide and synthetic agrochemicals on the control of larvae of Helicoverpa Armigera. The experiment consisted of a total of six treatments including control. There were a total of six treatments of the pesticides including control with four replicates and two application of the pesticides. The results indicate that the synthetic emamactin (T1) was the superior in controlling the larval population of pod borer with a % reduction of 63 and 88 after 1st and 2nd application. The chloropyifos showed better results next to emamactin 2nd spray. The neem bio-pesticide showed best results next to emamctin after the first application. The acetamiprid showed the least efficacy in control of pod borer larvae than all other treatments of pesticides.

A field experiment on influence of intercropping on the larval population of chickpea pod borer, Helicoverpa armigera (Hub.) in chickpea was conducted at Agricultural Research Farm of Brahmanand Post Graduate College, Rath, Hamirpur, Uttar Pradesh during 2016-17 and 2019-20. In Bundelkhand agro-climatic region the activity of chickpea pod borer was observed from last week of December to last week of March while, its peak activity was noticed at 9th, 10th and 11th SMW in chickpea agro-ecosystem. The infestation of chickpea pod borer (H. armigera) larvae was started from last week of December when the crop was in vegetative growth stage. Thereafter, its population increase gradually to reach maximum (1.72 larvae/mrl) at 10th standard (first fortnight of March) after that its population declined gradually till the harvesting of the crop. The chickpea intercropped with safflower, mustard, linseed, barley and marigold had significant influence in reducing the larval population of chickpea pod borer (H. armigera). The chickpea intercropped with marigold (0.71larva/mrl) and mustard (0.75larva/mrl) was found the most effective in reducing the larval population of H. armigera. It was followed by chickpea + linseed, chickpea + barley and chickpea + safflower intercropping systems. The maximum population of chickpea pod borer was observed in chickpea sole crop (1.07larvae/mrl).
