Effect of temperature on biology of red spider mite (Oligonychus coffeae)on three different TV clones

An experiment to study the effect of temperature and diet on growth and development of the red spider mite (RSM), Oligonychus coffeae Nietner (Acarina : Tetranychidae) revealed prolongation of life cycle period up to 18.79 days at 20°C, which, however, was reduced to 8.06 days at 35°C. The longevity...

Description
Summary:An experiment to study the effect of temperature and diet on growth and development of the red spider mite (RSM), Oligonychus coffeae Nietner (Acarina : Tetranychidae) revealed prolongation of life cycle period up to 18.79 days at 20°C, which, however, was reduced to 8.06 days at 35°C. The longevity of adult male and female were 12.7 and 28.3 days, respectively at 20°C. Amongst the TV (Tocklai Vegetative) clones of tea, TV was found to be the most preferred diet, followed by TV 10 and TV 6 1 . Fecundity was 120.7±21.74, 114.7±14.88 and 102.0±24.75 on TV 1 , TV respectivelyThe thermal constant needed for egg to adult formation ranged from 149.60 to 185.38 day°C on TV 6 and TV 1 10 clone.
