Abstract

The litchi, Litchi chinensis Sonn. is an important sub-tropical evergreen fruit crop. Among various insect pests of litchi, stink bug, Tessaratoma papillosa (Drury) is a major one causing extensive damage in Mizoram. The forecasting model to predict stink bug incidence in litchi was developed by ARIMAX model of weekly cases and weather factors. In exploring different prediction models by fitting covariates to the time series data, model × (mean maximum and minimum temperature, morning and evening relative humidity and rainfall) was found best model for predicting the stink bug incidence; all covariates were found significant predictors except evening RH, which did not have any significant covariates as predictor of stink bug incidence.
