INFLUENCE OF TEMPERATURE AND RELATIVE HUMIDITY ON LARVAL DEVELOPMENT AND SURVIVAL OF THE RICEMOTH, Corcyra cephalonica (STAINTON,

Abstract

Studies were undertaken to find out the influence of temperature and relative humidity on survival and development of the larvae of the ricemoth, Corcyra Cephalonica (Stainton) within a temperature range from 15° to 40° (at 5°C interval) end, selative humidities of 60 to 90 per cent (at 15 per cent interval) at each temperature. Lesser larval period (17.50 days) was observed at 35°C and 90 per cent R. H. Higher percentage of larval survival (78.33) was observed at 25°C and 90 par cent relative humidity.
