“…Los glucosinolatos se sintetizan y almacenan en las plantas al igual que la enzima mirosinasa, la cual hidroliza los glucosinolatos convirtiéndolos en productos biológicamente activos cuando el tejido vegetal se rompe por un daño mecánico, por ejemplo, el daño por M. ochroloma al alimentarse de la planta (Bridges et al 2002, Campas-Baypoli et al 2009). Cuando larvas y adultos muerden la hoja, la mirosinasa es liberada y entra en contacto con los glucosinolatos para iniciar la síntesis de los isotiocianatos (Bridges et al 2002), que poseen propiedades fungistáticas y actúan como un sistema de protección contra patógenos que afectan a las plantas (Lacey et al 1999, Zimmermann 2008. Estas sustancias pueden reducir la sobrevivencia de blastosporas de I. fumosorosea (Inyang et al 1999, Klingen et al 2002.…”

Resumen. El escarabajo de margen amarillo, Microtheca ochroloma Stål (Coleoptera: Chrysomelidae) es una plaga que causa pérdidas económicas en la producción de crucíferas (Brassicaceae) en Argentina y el sureste de los Estados Unidos. El control biológico utilizando el hongo entomopatógeno Isaria fumosorosea Wize (Hypocreales: Cordycipitaceae) es una alternativa para reducir las poblaciones de esta plaga. Este estudio evaluó el efecto que tiene este hongo en la cantidad de herbivoría por los adultos del escarabajo al ser alimentados con hojas aplicadas con I. fumosorosea. Se evaluaron cuatro concentraciones (0.1, 0.5, 1.0 y 2.0 g) de la formulación PFR-97 20% WDG cepa Apopka 97 por 100 ml de agua destilada y se usó como tratamiento control únicamente agua destilada. Se realizaron dos ensayos, cada ensayo con 10 plantas de bok choy por tratamiento, cada planta con seis escarabajos. A los 7 días se midió el área foliar consumida por los escarabajos. En el primer ensayo, las plantas aplicadas con 1.0 y 2.0 g/100 ml sufrieron significativamente menos daño que el control. Para el segundo ensayo hubo diferencia significativa entre el control y la concentración 2.0 g/100 ml. El control tuvo 3.7 y 2.0% más daño comparado con los demás tratamientos en el primer y segundo ensayo, respectivamente.Palabras clave: Brassicaceae, control biológico, hongo entomopatógeno, plaga. Effect of the Fungus Isaria fumosorosea Wize on Herbivory by Adult Yellowmargined Leaf Beetles,Microtheca ochroloma Stål (Coleoptera: Chrysomelidae)Abstract. The yellowmargined leaf beetle, Microtheca ochroloma Stål (Coleoptera: Chrysomelidae), is a pest that causes economic losses in the production of crucifers (Brassicaceae) in Argentina and the southeastern USA. Biological control using the entomopathogenic fungus Isaria fumosorosea Wize (Hypocreales: Cordycipitaceae) is an option for suppressing pest populations. This study evaluated the effect of this fungus on herbivory by adult beetles when they were fed leaves treated with I. fumosorosea. Four concentrations (0.1, 0.5, 1.0, and 2.0 g) of the formulation PFR-97 20% WDG Apopka strain 97 per 100 ml of distilled water and a distilled water only control were evaluated. Two trials each with 10 bok choy plants per treatment were performed, and each plant was infested with six adult beetles. On the seventh day, leaf area consumed by the beetles was measured. In the first trial, plants applied with 1.0 and 2.0 g/100 ml suffered significantly less damage than the control. In the second trial, there was a significant difference between the control and concentration of 2.0 g/100 ml. The control had 3.7 and 2.0% more damage compared to the other treatments in the first and second trials, respectively.

“…In another method, nymphs detached from leaves were kept on glass slides at 100% RH for at least 12h after spraying . A bioassay technique based on root formation of cabbage leaves in specific solutions was recently published by Lacey et al (1999). A simpler method, based on root formation of bean leaves maintained in Oasis  cubes embedded in water, was developed at the University of Vermont (M. Brownbridge -pers.…”

“…In bioassays with nymphs of the biotype B of B. tabaci, data are expressed as LC 50 values (Wraight et al 1998) or as an index based on the developmental stage of the fungus on the host and, less common, as percentage mortality. For example, when conidia or blastospores of two P. fumosoroseus isolates were applied onto eggs and 2 nd instar nymphs of the biotype B using rooted cabbage leaves as substrate, mortality rates ranged from eight to 20% for eggs, and from 27 to 68% for nymphs (Lacey et al 1999). In the referred paper, spraying was performed with a sprayer tower delivering 3.8x10 3 conidia / cm 2 , which is 1/3 of the dose used in the present study.…”

The fruiting body of Paecilomyces fumosoroseus was collected at Mt. Mani, Ganghwa Island, Korea in September, 2001. This study was carried out to obtain the basic informations for the mycelial growth and fruiting body production of P. fumosoroseus in artificial media. The optimal conditions for the mycelial growth were obtained at 25 o C and in the range of pH 6~9, respectively. P. fumosoroseus showed the favorable growth on Hamada medium. The carbon and nitrogen source favorable for mycelial growth were dextrin and histidine, respectively. Optimum C/N ratio suitable for optimal growth of P. fumosoroseus was observed on the culture media adjusted to the ratio of 40:1. The mycelial growth of P. fumosoroseus was optimal on corn meal agar supplemented with 30% of silkworm pupae. The most favorable fruiting body formation of P. fumosoroseus was obtained in the medium containing unpolished rice supplemented with 20% (w/w) silk worm pupae at 25 o C under 100 lux.
