The population of the Platynectes beetles in the rubber plantations of Kerala, was found to be governed by the climatic factors - like rainfall and temperature. These Climatic factors were found to influence the prevalence of beetle population and its density as well in the study areas. The number of rainy days per month and temperature were found to influence prevalence (%) of beetle in the rubber plantation areas of Kerala. The rainfall showed a positive linear correlation with the prevalence of Platynectes beetles in all the three study areas included in the study viz., Aimcompu (r = 0.609, p = 0.035), Chethackal, (r = 0.550, p = 0.063) and in Pampady, (r = 0.509, p = 0.090). However temperature showed a negative linear correlation with prevalence of Platynectes beetles in Aimcompu, (r = - 0.658, p = 0.019), Chethackal, (r = - 0.710, p = 0.096) and in Pampady, (r = - 0.806, p = 0. 001). Also the rainfall showed a positive linear correlation with the density of Platynectes beetles in all the three study areas included in the study viz., Aimcompu (r = 0.595, p = 0.041), Chethackal, (r = 0.785, p = 0.002) and in Pampady, (r = 0.589, p = 0.043). However temperature showed a negative linear Correlation with density of Platynectes beetles in Aimcompu, (r = - 0.586, p = 0.045) Chethackal, (r = - 0.682, p = 0.014) and in Pampady, (r = - 0.800, p = 0. 001).
