Abstract
Studies on the seasonal abundance of Acalitus hibisci Mondal and Chakrabarti on Hibiscus vitifolius indicate that the variation in the population of the mites is positively correlated with different abiotic factors, such as, temperature, relative humidity and rainfall. It has been found that the population of mites during winter months is 5 times less than that in the summer months. Mite movement during daytime is the least during noon i.e. from 12.30 hrs to 13.30 hrs while number of mites coming out of the gall shows a notable increase during morning. A slight increase in activity was also found during afternoon in some months.
