| dc.description.abstract | Seasonal fluctuations in the population density of tea mosquito, Helopeltis antonii Signoret, were studied during June 1972 to May 1977 at weekly intervals. The build up of pest population commenced in October - November synchro^ nising with the emergence of new flushes in cashew after the cessation of monsoon showers. The pest population reached its peak in January. Tea mosquito was active in the field in different degrees of intensity till May. The population build up of the pest was found to be negatively correlated with the meteorological factors like minimum temperature, minimum relative humidity and rainfall and positively with sunshine. The most favourable period for the rapid multiplication and population build up of the pest was between December to February. During the monsoon season, tea mosquito population was totally absent. | en_US |
