A study on the effects of certain abiotic factors on the activity ofAdoretus epipleuralis Arrow (Coleoptera: Scarabaeidae)
The effect of certain abiotic factors viz. temperature relative humidity and soil moisture has been revealed on the activity ofAdoretus epipleuralis Arrow. This beetle was caught with the help of Pilani type light trap operated daily for 2 years (1976, 1977) from dusk to dawn at Pilani (Pilani is on the North-eastern side of Jhunjhunu District of Shekhawati Region in semi-arid zone of Rajasthan, India. Its geographical position is 28°20′ N latitude and 75°35′ E longitude and 330 mase.) To ascertain in mathematical terms the extent of relationship between the prevailing weather conditions and the light trap catches ofAdoretus epipleuralis, regression analysis, partial regression analysis, multiple linear regression analysis and β-coefficient analysis have been exercised.
