Incidence of the yellow jute mite Polyphagotarsonemus latus (Acari: Tarsonemidae) depending on the growing season, day hours, sowing time, plant canopy and plant age in Bangladesh (original) (raw)

2020, Israel Journal of Entomology

The yellow jute mite<em> Polyphagotarsonemus latus</em> is one of the major pests of jute in Bangladesh. The objectives of this research focussed on establishing the incidence of the yellow jute mite depending on the sowing date, plant age, growing season, hours of the day, environmental variables (temperature, relative humidity (RH) and rainfall), and plant morphology. Three major peaks of the mite population density were recorded: 80.75 mites/cm<sup>2</sup> on 9 June, 74.25 mite/cm<sup>2</sup> on 2 June, and 63.75 mites/cm<sup>2</sup> on 26 May 2011. The prevailing dry conditions (ca. 80 % RH) with moderately high temperatures and without rainfall were found to be favourable for the population build-up; rainfall had a strong negative direct effect on the yellow mite population density. The highest mite population density was observed at noon (64.42 mites/cm<sup>2</sup>), with significantly lower counts during morning (48....
