Pest spectra, succession and its yield losses in mungbean and urdbean underchanging climatic scenario

Performance of Improved Integrated Pest Management (IPM) Technology Component for Enhancing the Productivity of kharif Black Gram (Vigna mungo L.) under Cluster Front Line Demonstration at Malda, West Bengal

“…This project was implemented by Krishi Vigyan Kendra, Malegaon of Zone-V with main objective to boost the production and productivity of pulses through CFLDs with latest and specific technologies (Khedkar et al, 2017). According to Duraimurugan and Tyagi (2014), the avoidable losses due to pest complex on different varieties of urdbean ranged from 15.62 to 30.96% with an average of 24.03%.The annual yield loss due to the insect pests has been estimated at about 30 per cent in urd bean and mung bean (Gupta and Bhattacharya, 2008).Fungal foliar diseases especially Cercospora leaf spot, web blight and powdery mildew have emerged as the most important ones and have been found causing immense loss in farmers' field (Akhtaret al, 2014). Cercospora leaf spot causes 0.0-100.0 per cent yield loss in wet season (Pandey et al, 2009).…”

Estimation of Avoidable Yield Loss Due to Sucking Pest Complex in Blackgram

“…monocrotophos 36% SC and fipronil 5% SC at ten days intervals against sucking pests viz., whiteflies, thrips, aphids and leafhoppers in blackgram. (Duraimurugan and Tyagi, 2014). Estimation of avoidable yield losses makes one to understand the damage levels caused by the insect pests and allows one to take preventive measures without causing economic damage.…”

“…Gupta and Bhattacharya (2008) reported that the annual yield loss due to the insect pests has been at about 30 per cent in blackgram and greengram. Duraimurugan and Tyagi (2014) reported that the avoidable yield losses due to pest complex on different varieties of greengram ranged from 27.03 to 38.06 percent with an average of 32.97 per cent. The avoidable yield losses due to pest complex on different varieties of blackgram ranged from 15.62 to 30.96 per cent with an average of 24.03 per cent.…”

Abundance of Major Insect-Pests Infesting Green Gram and Its Associated Natural Enemies

“…The population increased gradually and reached to its peak in the 1 st week of September (36 th SMW) with mean population of 10.45/5 plants. Pawar et al, (2014), Duraimurugan and Tyagi (2014), Singh and Singh (2014), Kumar and Kumar (2015) and Yadav et al, (2015).…”
