Sublethal effects associated with resistance to indoxacarb in diamondback moth

Plutella xylostella is one of the most important pests of brassicaceous crops around the world. Indoxacarb is widely used to control lepidopteran pest larvae. This insecticide has slow activity and prolonged residual effects which impact the habits and physiology of pests. The objective was to evalu...

Indoxacarb is widely used to control lepidopteran pest larvae. This insecticide has slow activity and prolonged residual effects which impact the habits and physiology of pests. The objective was to evaluate the effect of sublethal concentrations of indoxacarb on the biology and development time of the diamondback moth. Selection pressure of the insecticide indoxacarb was carried out on P. xylostella, applying the LC20 of the previous generation for the next ten generations, the LC20 of the resistant line (G10) was calculated and this concentration was subsequently applied to L3 larvae. The effect on the percentage and weight of pupae, adult emergence and oviposition for two generations was evaluated; in addition, the development time of egg, larva, pupa and adult. The results showed that resistance and exposure to LC20 of indoxacarb caused changes in the biology and development of P. xyllostella. This was manifested in an increase in the percentage and weight of formed pupae and emergence of adults, along with a prolongation of development time of more than 10 days. However, a decrease of more than 50% in the number of eggs per female was observed. Plutella xylostella es una plaga de las más importantes en los cultivos de brassicaceas alrededor del mundo. El indoxacarb se utiliza ampliamente para el control de larvas de lepidópteros plaga. Este insecticida presenta una actividad lenta y efectos residuales prolongados los cuales impactan los hábitos y la fisiología de las plagas. Como objetivo se estableció la evaluación del efecto de concentraciones subletales de indoxacarb en la biología y tiempo de desarrollo de la palomilla dorso de diamante. Se realizó presión de selección del insecticida indoxacarb sobre P. xylostella, aplicando la CL20 de la generación anterior por las siguientes diez generaciones, se calculó la CL20 de la línea resistente (G10) y posteriormente se aplicó esta concentración a larvas de L3. Se evaluó el efecto en el porcentaje y peso de pupas, emergencia de adultos y oviposición para dos generaciones; además, del tiempo de desarrollo de huevo, larva, pupa y adulto. Los resultados mostraron que la resistencia y la exposición a CL20 de indoxacarb provocaron cambios en la biología y el desarrollo de P. xyllostella. Esto se manifestó en un aumento del porcentaje y peso de pupas formadas y emergencia de adultos, junto con una prolongación del tiempo de desarrollo de más de 10 días. Sin embargo, se observó una disminución de más del 50% en el número de huevos por hembra.
