The jute yellow mite Polyphagotarsonemus latus constitutes one of the major pests of jute crop in Bangladesh. The objective of this work was to study the biology of the P.latus, to determine its temperature-humidity responces in jute (Corchorus olitorius L.) var. O-9897. Bionomics of jute yellow mite, Polyphagotarsonemus laenerationtus (Banks) were studied in the laboratory of Bangladesh Jute Research Institute during March 2013 to September 2013. The incubation period of yellow mite on the variety O-9897 was 1.95 days for female and 1.90 days for male; larval period of 1.00 days for female, 0.75 days for male ; pupal period of 0.70 days for female and 0.71 days for male ; egg-adult period of 3.65 days for female and 3.44 days for male were highest in the 1st generation with 25.55±0.15oC and 56±1.47% relative humidity among three generations. pre-oviposition and oviposition period was o.65 days and 12.25 days. The highest longevity 13.45 days for female and 8.50 days for male. The daily mean of eggs were 2.20, 1.91 and 1.75 eggs in three successive generations. The number of eggs laid per female in her life time was 28.6, 24.8 and 12.2 eggs.
