Investigation of cotton bollworm (Helicoverpa armigera) damage with remote sensing technology.

Abstract

Helicoverpa armigera (cotton bollworm) is an invasive insect pest with significant damage. It is important to clarify the factors affecting its damage localization, as well as to investigate the damage monitoring options. Relationship between damage of cotton bollworm and different elements of environment have been investigated. Strong correlation have been found between the damage and the condition of the vegetation using spectral-based remote sensing technology. There was significant negative correlation between drone as well as satellite recorded NDVI of maize field and Helicoverpa armigera damage. Based on our research, spectral remote sensing is suitable not only for detecting damage caused by pests consuming vegetative plant parts, but also for the localization of pests feeding on generative parts whose damage is not visible directly as discoloration.
