Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) is serious insect- pest of chickpea crop in India. Egg laying behavior of H. armigera in different phase of lunar were studied under field condition during of rabi 2015-16 and 2016-17. Two types of cages one transparent, (cage A) and dark control cage (cage B) were used for the study. The results shows that in cage A egg laying was 11.00 per cent higher and 3.00 percent lower as compared to cage B in ascending and descending phase of lunar cycle and it was 8.00% higher in ascending over descending phase. Data further showed that 20.00% and 4.00% higher egg laying was observed in waxing crescent and waxing gibbous over waning crescent and waning gibbous of ascending and descending cycle respectively. Statically correlation was non-significant.
