Morphometrics of Brown Planthopper, Nilaparvata lugens (Stål) Populations Collected from Different Locations of India

V. Ratnakar, V. Jhansi Lakshmi, C. Srinivas, R. Jagadeeshwar & Satendra K Mangrauthia · Journal of Experimental Agriculture International · 2025

Morphometrics -the quantitative analysis of form-serves as a powerful tool in this context. It involves precise measurements of various body parts and is widely used in systematics to study morphogenesis, population structure, and the effects of environmental stress on organisms,...
