Abstract

Melon is one of the most exported fruits from Brazil. The leafminer fly, Liriomyza sativae (Blanchard) (Diptera: Agromyzidae), is one of the major problems that negatively interfere in the productivity increase in this crop. Chemical control is the most adopted method for this pest; however, producers have reported reduced susceptibility to insecticides. Thus, this study aimed to evaluate the susceptibility of L. sativae larvae to abamectin, cyromazine, and cyantraniliprole from populations collected from two melon crop-producing regions in Northeast Brazil (Juazeiro, BA and Icapuí, CE). The insecticide's lethal concentration 50 (LC50) was obtained in the laboratory using the leaf dip bioassay method with L. sativae larvae. No difference was observed in the LC50 between the populations for the three insecticides. Both populations showed low variation susceptibility for abamectin, cyromazine, and cyantraniliprole.

Summary

Introduction

This study aimed to evaluate the susceptibility of L. sativae larvae to abamectin, cyromazine, and cyantraniliprole from populations collected from two melon crop-producing regions in Northeast Brazil (Juazeiro, BA and Icapuí, CE). The leafminer fly, Liriomyza sativae (Blanchard) (Diptera: Agromyzidae), is one of the major problems that negatively interfere in the productivity increase in this crop (Costa-Lima et al 2015). In the melon-producing regions in Brazil, the problematic control of L. sativae with synthetic insecticides has led to studies aiming to search for different control methods, such as botanical insecticides (Oliveira et al 2020) and biological control (Costa-Lima et al 2019). The present study aimed to evaluate the susceptibility of populations of L. sativae to three major synthetic insecticides used in melonproducing regions in Northeast Brazil
