 en Entomopathogenic fungi isolates selection for egg control of tomato moth Tuta absoluta check for this species in other resources Meyrick (Lepidoptera: gelechiidae) eggs
Rodríguez, Marta S.; Gerding, Marcos P. & France, Andrés I.

Abstract

A pathogenicity study of 64 Metarhizium anisopliae check for this species in other resources var. anisopliae and 70 Beauveria bassiana check for this species in other resources isolates against tomato moth Tuta absoluta check for this species in other resources eggs, was carried out under laboratory conditions. The first evaluation was accomplished by spraying suspensions of 107 conidias mL-1 of each isolate directly on eggs, through a Potter tower. Mortality and conidia production on the eggs were significantly higher with the isolates M. anisopliae Qu-M558 and B. bassiana Qu-B911, Qu-B912 and Qu-B928. These isolates were newly evaluated using increasing conidia concentrations (0 to 108 conidia mL-1) of each of the five selected isolates. The isolates Qu-B912 and Qu-M558 produced the highest mortality percentages based on the area under mortality progress curve for each concentration, 80 and 60%, respectively.

 es Selección de aislamientos de hongos entomopatógenos para el control de huevos de la polilla del tomate, Tuta absoluta check for this species in other resources Meyrick (Lepidoptera: gelechiidae)

Resumen

Se realizó un estudio en laboratorio sobre la patogenicidad de 64 aislamientos de Metarhizium anisopliae check for this species in other resources var. anisopliae y 70 de Beauveria bassiana check for this species in other resources , en huevos de polilla del tomate Tuta absoluta check for this species in other resources . La primera evaluación se realizó por aplicación directa de suspensiones de 107 conidias mL-1 para cada aislamiento, con el sistema de pulverización de la torre de Potter. La mortalidad y esporulación sobre huevos fueron significativamente mayores con los aislamientos M. anisopliae Qu-M558 y B. bassiana Qu-B911, Qu-B912 y Qu-B928. Estos aislamientos fueron evaluados nuevamente en suspensiones crecientes de 0 a 108 conidias mL-1. Los aislamientos Qu-M558 y Qu-B912, produjeron los mayores porcentajes de mortalidad sobre la base del cálculo del área bajo la curva del progreso de mortalidad de huevos, 80 y 60%, respectivamente.

Palabras-clave
control biológico, polilla del tomate, patología de insectos.
