Description India is the largest producer and consumer of pulses
accounting for almost 33% of world area. The chickpea
marked a significant increase in area (9.96 million ha) for
the year 2013-14 which is highest in last 10 years. Similarly,
the chickpea production (9.92 million tonnes) also
surpassed record with in the history of India since last 50
years (Anonymous, 2014). Helicoverpa armigera is a
conundrum and one of the most dominant insect pests
in agriculture, accounting for half of the total
insecticides usage in India for protection of crops. The
problem of this pest is magnified due to its direct
attack on fruiting structures, voracious feeding habits,
high mobility and fecundity, multivoltine nature,
overlapping generations, nocturnal behaviour etc.,
(Sarode, 1999). At the same time adequate ecological data
is prerequisite for integrated pest management, which
can therefore be enhanced after determining the
seasonal abundance (Mathur et al., 2003). There are
many environmental factors which influence the insect
pest populations (Lode and Sharma, 1993). Among them
abiotic factors play a vital role in multiplication and
distribution of insect pests. The knowledge on the
seasonal incidence of gram pod borer will certainly found
to be helpful in formulating the insect pest management
strategies for Helicoverpa armigera at Pantnagar
condition. Therefore, an attempt has been made to work
out the effect of different abiotic factors on the seasonal
incidence of pod borer, H. armigera in chickpea...
