“…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.

“…The genus Paecilomyces is a mitosporic fungus that has a wide natural distribution and several entomopathogenic species (Alves, 1998;Steinkraus, 2006;Zimmermann, 2008;Sun and Liu, 2008). Although this entomopathogen infects several pests (Alves, 1998), this is the first record of its attack on N. ribisnigri.…”

Nasonovia ribisnigri is a key pest of lettuce (Lactuca sativa L.) in Brazil that requires alternative control methods to synthetic pesticides. We report, for the first time, the occurrence of Paecilomyces niveus as an entomopathogen of the aphid Nasonovia ribisnigri in Pinhais, Paraná, Brazil. Samples of mummified aphids were collected from lettuce crops. The fungus P. niveus (PaePR) was isolated from the insect bodies and identified by macro and micromorphology. The species was confirmed by sequencing Internal Transcribed Spacer (ITS) rDNA. We obtained a sequence of 528 bp (accession number HQ441751), which aligned with Byssochlamys nivea strains (100% identities). In a bioassay, 120 h after inoculation of N. ribisnigri with pathogenic P. niveus had an average mortality of 74%. The presence of P. niveus as a natural pathogen of N. ribisnigri in Brazil suggests that it may be possible to employ P. niveus to minimize the use of chemical insecticides.Keywords: Lactuca sativa, Aphididae, entomopathogenic fungi, biological control.

“…fumosorosea (formerly known as Paecilomyces fumosoroseus) is a well-known entomopathogenic fungus with a worldwide distribution in temperate and tropical zones (Zimmermann 2008). This fungus is utilized for controlling many pest species worldwide (Mesquita et al 1996;Gökçe and Er 2005;Zimmermann 2008;Avery et al 2010). Chapin et al (2006) showed that there was a decrease of 52% of the winter population of C. ciliata within 14 days after spraying of P. fumosoroseus.…”

IntroductionCoastal zones, considered to be a valuable economic and environmental resource for human and marine habitats, are the most dynamic natural environment of any region on earth. Changes in the ocean-climate system and increasing human activities in these regions make the coastal areas more susceptible to natural hazards and more costly to live in. One of the most serious problems is the accelerated sea level rise and its resulting physical impacts on the coastal zones. Any rise in the mean sea level may result in the retreat of unprotected coastlines due to coastal inundation, erosion, and increased storm flooding (Nicholls et al. 1995). As emphasized in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4), the global sea level rose by 1.8 to 3.1 mm/year during the last century and present estimates of future rise range from 18 cm to 59 cm by the year 2100 (Solomon et al. 2007). Low lying areas such as beach ridges, coastal plains, deltas, estuaries, lagoons, and bays would be the areas that would suffer the most as a result of the enhanced sea level rise. Thus, it is essential to quantify the response of coastal systems to sea level change, as well as to assess the potential threats posed to human and marine biodiversity.A near global comparative analysis by Dasgupta et al. (2007) regarding the impact of permanent inundation due to sea level rise on 84 developing countries revealed that hundreds of millions of people in the developing world are likely to be displaced by a sea level rise of 1 to 5 m within this century. Accompanying economic and ecological damage will be severe for many. Approximately 0.3% (194,000 km 2 ) of the territory of the 84 developing countries would be impacted by a 1-m rise. This would increase to 1.2% in areas where the sea level rose 5 m. Nearly 56 million people (approximately 1.28% of the population) in these countries would be impacted under a 1-m rise scenario. This would increase to 89 million people for 2 m and 245 million people (approximately 5.57%) for a 5-m rise. The impact of sea level rise on gross domestic product (GDP) is slightly greater than the impact on population, because GDP per capita is generally above average for coastal populations and cities. Wetlands would experience significant impact even with a 1-m rise. Up to 7.3% of wetlands in the 84 countries would be impacted Abstract: With the rising sea level becoming a more pressing issue to coastal areas, a comprehensive analysis has been conducted to assess the vulnerability of the Çukurova Delta under the projected inundation by the end of the century. The level of inundation was estimated from a multimission satellite altimetry sea level anomaly and significant wave height data between September 1992 and February 2012. Superposed to the clear annual oscillation with 6.2 cm amplitude peaking around the beginning of October, the mean sea level signal exhibits a positive trend of 3.4 ± 0.1 mm/year over the altimetric data period. The extreme wave height with a 100-year ...
