“…The number of dead hearts (DH) and/ or white ear heads (WEH) were counted and the percent incidence of stem borer was arrived at by using the formula given by Justin and Preetha (2013). The incidence of leaf folder was recorded based on the percentage of leaf damage calculated as formula given by Kumar et al (1996). Data on various weather parameters, viz., temperature (maximum and minimum), humidity (morning and evening), rainfall and wind speed were recorded at the agrometeorology observatory, College of Agriculture, Balaghat, Madhya Pradesh.…”

The production and productivity of rice is constrained by various insect pests but very meagre information is available on the seasonal incidence of the Crambidae pests of rice in the subtropical region of Madhya Pradesh. The present study was undertaken on the seasonal incidence of Crambidae pests at the Regional Agricultural Research Station, College of Agriculture, Balaghat, Madhya Pradesh during January -May, 2022. Rice variety JRB-1 was sown in a 300 m2 plot, damage of pests were recorded and correlated with the weather data. Stem borer damage manifested in the form of deadhearts and white ears, started from second fortnight of February and gradually increased till late April. Leaf folder incidence was observed from early March to early April. Incidence of these were found to be correlated positively with temperature and wind velocity whereas, negatively with relative humidity and rainfall. The pattern of incidence of these pests of rice in the subtropical region of central India (Balaghat, MP) were more or less similar to those of the tropics.

“…Pigeon pea pod fly M. obtusa (Malloch) is a more detrimental pest and infests 12 to 100 per cent pods. The pod fly emerged as a key pest and causing10 to 80 per cent damage (Kumar et al, 2003) and estimated to cause a monitory annual loss of US$256 million (Arbind et al, 2013). It was observed that the damage of 22.5%, 21% and 13.2% in North India, Central India and South India, respectively, (Lateef et al, 1981).…”

Background: The pod fly, Melanagromyza obtusa (Malloch) is one of the major biotic constraints in increasing production and productivity of pigeonpea crop throughout the country and it causes up to 100 per cent losses in field condition. Injudicious use of pesticides against this destructive pest, further ignites the problem of resistance, resurgence and environmental and ecological imbalances. Methods: Experiments were conducted at Banda University of Agricultural and Technology, Banda during kharif, 2020 and 2021. To estimate the bio-efficacy of insecticides for the management of M. obtusa in pigeonpea the experiment was laid out in randomized block design (RBD) with eight treatments and three replications. Pod and grain damage were assessed and C:B ratio was calculated. Result: First appearance of pod fly was noticed in third standard week. Throughout cropping period highest pod damage was recorded in eighth standard week and lowest pod damage was recorded in twelfth standard week. Emamectin benzoate 5 SG @ 11g a.i./ha + Dimethoate 30 EC @ 300 g a.i./ha was the best treatment as it exhibited minimum pod damage and highest yield.
