A pest scout data in pigeonpea (leaf webber, plume moth, pod borer) and chickpea (pod borer) crops including daily insect pest
counts for three successive seasons (2015/16—2017/18) at western and eastern plateau hills (agro-climatic zones) of India was
analysed for spatio-temporal dynamics. Longer infestation (different crop phenological growth stages) behaviour of leaf webber
and pod borer in pigeonpea and chickpea, respectively influenced their increased mean counts (incidence). Weekly mean counts
of leaf webber, plume moth and pod borer in both the crops varied significantly between the seasons. Linear incremental change
in mean counts of leaf webber and pod borer on pigeonpea and chickpea, respectively was observed across the seasons (interseasonal).
Intra-seasonal built-up of plume moth (pigeonpea) and pod borer (pigeonpea and chickpea) mean counts was also
noticed. On pigeonpea, leaf webber and plume moth mean counts never reached an economic threshold level (3 larvae/plant), but
crossed the advisory level (1.5 larvae/plant). It was observed that there was incremental rise in pod borer mean counts and
crossing economic threshold level over seasons in chickpea (1 larvae/m row length), while it was not the case in pigeonpea (1
larvae/ plant). Furthermore, survival and management strategies of leaf webber, plume moth and pod borer in pigeonpea and pod
borer in chickpea were discussed.
