“…The significant increase in the survival of caterpillars exposed to hybrids with Vip3a20 technology within three generations corroborates with the obtained results by Miraldo et al (2016), where the exposure of S. frugiperda to Vip3Aa20 maize resulted in the survival of around 20% of caterpillars. Bernardi et al (2015a) cite that, due to technology misuse, the fall armyworm may develop resistance to Vip3Aa20 toxins.…”

“…Models generally affirm that larval dispersal leads to faster evolution of resistance in a blended than in a block refuge system [17,50], unless substantial (but, unfortunately, realistic) grower noncompliance is included for the latter [51 ]. Recent research indicates that larval movement in several lepidopteran pest species is a threat to the blended refuge strategy [52][53][54]. Although less extensive than lepidopteran caterpillars, dispersal rate of subterranean rootworm larvae between adjacent plants is high enough [55] to potentially compromise a blended refuge strategy, as observed in laboratory evolution experiments [56].…”

“…Como consecuencia, asegurar la adopción de refugio puede ser un problema (Carroll et al, 2013). De hecho, el bajo compromiso de cumplimiento de refugio ha sido considerado como uno de los factores que contribuyeron a generar resistencia en la mayoría de los casos reportados (van Rensburg, 2007;Dhurua & Gujar, 2011;Gassmann et al, 2011;Storer et al, 2012;Monnerat et al, 2015;Miraldo et al, 2016;Chandrasena et al, 2018). En nuestro país, desde los primeros años el nivel de adopción de áreas refugios por parte de los productores que utilizan maíz Bt no estuvo en los niveles esperados (Aragón, 2004).…”

“…En un análisis inicial, Mallet & Porter (1992) utilizaron modelos matemáticos para identificar los aspectos técnicos preocupantes sobre el manejo de la resistencia relacionados al movimiento de larvas en refugios integrados. Primero, el movimiento de un insecto desde una planta Bt a una no Bt luego de una exposición subletal, o desde una planta no Bt a una Bt luego de adquirir mayor tamaño y con ello mayor tolerancia a las toxinas, puede conducir a un mayor fitness relativo de los individuos heterocigotas, acelerando la evolución de la resistencia (Mallet & Porter, 1992;Brévault et al, 2015;Carrière et al, 2016;Miraldo et al, 2016). Este riesgo es mayor para plantas Bt con una sola toxina debido a que la dispersión entre plantas Bt y no Bt reduce la cantidad de toxina recibida por el insecto en movimiento (Onstad & Gould, 1998;Davis & Onstad, 2000).…”
