Cuticle thickening mediates insecticide penetration resistance in Spodoptera litura.

ABSTRACT:

Introduction

Long-term and extensive use of chemical pesticides has led to the development of resistance in many important agricultural pests. The mechanisms of resistance formation in pests are complex and variable, and unraveling the resistance mechanisms is the key to control resistant pests. Insect cuticle, as the first line of defense for insecticides, plays a non-negligible role in insecticide penetration resistance. Although penetration resistance is widespread in insects, the multiple molecular mechanisms that impede insecticide penetration are unclear, especially in Spodoptera litura.

Objectives

This study aims to reveal the molecular mechanisms of insecticide penetration resistance in S. litura.

Methods

The structure and thickness of cuticle were analyzed by
