Weather forecasting model for lace bug, Cochlochila bullita (Stål) (Hemiptera: Tingidae) on Tulsi crop

Abstract

The present study, Lace bug, Cochlochila bullita (Stal) on Occimum basilicum L. was recorded continuously during the 38th to 1st meteorological weeks of the year 2015-16, 2016-17 and 2017-18. The peak population of Lace bug, Cochlochila bullita (Stal) was recorded on 47th (2015-16), 48th (2016-17) and 44th (2017-18) meteorological week that coincide moderate range of environmental factors of the growing season of crop Occimum basilicum and its population buildup. The influence of weather factor such as rainfall showed negative correlation as well as negative regression. Highly negative significant regression coefficient was found in the year of 2015-16 and 2016-17 in the comparison to 2017-18. The forecasting model was based on rainfall received that could be Y (population number) = intercept + [(-) significant regression coefficient (b) rainfall].
