Tetranychus urticae Koch (Acari: Tetranychidae) is a serious pest in cotton fields worldwide. Monitoring of T. urticae with time-series of vegetation index and climatic factors based satellite data was applied to near real-time assessing. The current study aimed to determine correlations between T. urticae population dynamic and effects of Aerosol index of Sentinel-5, Sentinal-2-NDVI (10m), The Land Surface Temperature (LST), MODIS-Evapotranspiration (ET) and CHIRPS-precipitation. Spider mite out-breaking has coincided with the wheat harvesting and where experienced several dusty days with high aerosol index 0.167. Rainfall had a significant negative correlation with T. urticae population (R2 = 0.378) and a threshold precipitation level was estimated at least 2 mm to clean up the canopy. We could not find a significant pattern between temperature and T. urticae population until August 2020 and then the significant positive relationships were observed during August 2020, R² = 0.3519, 0.1283, 0.1675 and 0.178, weekly. Evapotranspiration depicted a statistically synchronous relationship R2 = 0.637 with T. urticae dynamism. There was a positive correlation between increasing NDVI and T. urticae population until August 2020 and then was shifted to negative pattern R2 = 0.273 and 0.139. These findings, aerosol index of sentinel-5 and MODIS-evapotranspiration have potential to forecast spider mite population with high temporal resolution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
