Study the influence of climate change on Clavigralla gibbosa(Spinola)in pigeonpea

Abstract

Monitoring and population dynamics of tur pod bug, Clavigralla gibbosa in unprotected pigeonpea crop during kharif seasons from 2011 to 2014 at the Farmers field of Jurdcial area of S.D. Agricultural University, S.K. Nagar, North Gujarat, India. Temperature, rainfall and host-plant species were analyzed with respect to population fluctuation of the tur pod bug. The observations revealed that, the average number of larval population per plant in the season (from 27 th to 3 rd standard weeks) was 0.97, 0.32, 0.30 and 0.38 larvae per plant during 2011, 2012, 2013 and 2014 respectively. Population of C. gibbosa had significant and negative correlation with maximum temperature (r= -0.73), rainfall (r= -0.29) and relative humidity (r= -0.79, r= -0.58 morning and evening, respectively).

Analysis of Microenvironment Data Using Low-Cost Portable Data Logger Based on a Microcontroller

“…Temperature and humidity data from the respective environment are critical, especially in this era of global warming. Climate change has an indirect and direct impact on forests because it affects a wide range of tree species with varying ecological requirements, as well as all organisms of the ecosystem (3). Temperature and humidity also have a considerable impact on the physiological and ecological features of plants as one of the key factors regulating plant productivity and distribution (4).…”
