Investigadores del INTA avanzan en la cr\u00eda de Tamarixia radiata, un enemigo natural que disminuye las poblaciones de Diaphorina citri -vector que transmite la enfermedad- y permite el control de la plaga sin productos qu\u00edmicos en zonas urbanas.<\/h3>\n<\/blockquote>\n

Con una producci\u00f3n anual de 2,65 millones de toneladas, limones, naranjas y mandarinas son el motor de las econom\u00edas regionales del NOA y NEA. Sin embargo, para consolidarse en el mercado internacional, t\u00e9cnicos y productores deben agudizar el ingenio para frenar el avance del Huanglongbing en la Argentina. Para esto, el laboratorio de Entomolog\u00eda del INTA Bella Vista \u2013Corrientes\u2013 avanza en la cr\u00eda de Tamarixia radiata, un parasitoide que disminuye las poblaciones de la chicharrita que trasmite la enfermedad. Para el manejo integrado de plagas eval\u00faan, adem\u00e1s, el cris\u00f3pido Ceraeochrysa Sp.<\/p>\n

Alcides Aguirre, referente del laboratorio de Entomolog\u00eda del INTA Bella Vista, destac\u00f3 la importancia de contar con un controlador biol\u00f3gico que regule las poblaciones de Diaphorina citri \u2013chicharrita que transmite HLB\u2013. \u201cNos enfocamos en el estudio de la avispa Tamarixia radiata para conocer su comportamiento, criarla y liberarla en los alrededores de plantaciones citr\u00edcolas\u201d, se\u00f1al\u00f3 en INTA Informa.<\/p>\n

Por la capacidad destructiva que tiene esta enfermedad \u2013una vez infectada la planta no se recupera\u2013, investigadores de todo el mundo trabajan en el desarrollo de tecnolog\u00edas y pr\u00e1cticas para su prevenci\u00f3n. De hecho, estudios experimentales realizados en el Instituto Nacional de Investigaci\u00f3n Agropecuaria (INIA) de Uruguay registraron parasitismos de la avispa cercanos al 80 % en las poblaciones de Diaphorina citri.<\/p>\n

En la Argentina, las reglas para evitar su avance en plantaciones comerciales de citrus son claras. Adem\u00e1s de producir con plantas provenientes de viveros certificados, el control de la chicharrita se puede hacer con productos qu\u00edmicos.<\/p>\n

Sin embargo, \u201cen los programas de prevenci\u00f3n no est\u00e1 prevista ninguna medida para disminuir su poblaci\u00f3n en zonas urbanas con citrus o mirto (arbusto ornamental) ni en quintas abandonadas\u201d, expres\u00f3 Aguirre y agreg\u00f3: \u201cPor esto, desde el laboratorio de Entomolog\u00eda avanzamos en la producci\u00f3n masiva de la avispa que nos permite el control de la plaga sin productos qu\u00edmicos\u201d.<\/p>\n

La avispa Tamarixia radiata es un parasitoide natural de Diaphorina citri \u2013ps\u00edlido asi\u00e1tico de los c\u00edtricos\u2013, esto significa que la hembra pone un huevo sobre su hu\u00e9sped, acci\u00f3n que eventualmente le provocar\u00e1 la muerte. \u201cEstudios realizados en Florida \u2013Estados Unidos\u2013 demostraron que la avispa puede disminuir con \u00e9xito las poblaciones de la chicharrita y reducir el impacto de la enfermedad\u201d, indic\u00f3 Aguirre.<\/p>\n

Para entender todas las dimensiones sobre el comportamiento del vector, en la localidad correntina de Bella Vista, el equipo de investigadores liderado por Aguirre comenz\u00f3 con el cultivo de la planta hospedera \u2013Murraya paniculata\u2013 conocida como mirto, continu\u00f3 con la reproducci\u00f3n masiva del ps\u00edlido asi\u00e1tico de los c\u00edtricos y, ahora, se encuentra en la etapa de multiplicaci\u00f3n del parasitoide.<\/p>\n

\u201cHace varios a\u00f1os que estamos observando y estudiando la chicharrita y el parasitoide\u201d, indic\u00f3 Aguirre, quien a\u00f1adi\u00f3: \u201cSi podemos contar con la infraestructura necesaria se podr\u00eda pensar que, en 2020 a m\u00e1s tardar, podremos hacer las primeras liberaciones masivas de la avispa y evaluar los resultados a campo\u201d.<\/p>","protected":false},"excerpt":{"rendered":"
