Producción y manejo del hongo Metarhizium anisopliae (Metch) sor [1998]

This variability could also explain sensitivity to hohgo chemical products Alves et al. The amplified fragments were separated by horizontal gel electrophoresis in 1.

The fungus then develops inside the body, eventually killing the insect after a few days; this lethal effect is very likely aided by the production of insecticidal cyclic peptides destruxins. These groups demonstrate the existence of genetic heterogeneity among the M.

According to our results, these variables are not related.

Metarhizium anisopliae – Wikipedia

This page was last edited on 29 Decemberat The commercially important isolate M. It is possible that this action mechanism has affected the evaluated strains; however, there are no known reports of the effect of fenhexamid on EF. Regarding isolate geography, the two isolates obtained from A.

Variations in band intensity were not considered as differences. Estimation of fungal genetic diversity.

The area is predominantly characterised by a Cambisol soil type. However, there is background information about the different degrees of EF fungicide tolerance. Dishes were incubated in the same conditions as in the previous stage. One of the subgroups was made up of two isolates CD and AS which were collected in two sugarcane fields that were located nearby 1. Subsequently, the growth rate for each active ingredient, concentration, and strain was calculated for these colonies.


From Wikipedia, the free encyclopedia. Kresoxim-methyl modification of a naturally occurring compound to produce a new fungicide. It is probable that this action mechanism can occur in fungi cultivated in vitrobut not necessarily for in situ conditions. Universidad y Ciencia Chilean Journal of Agricultural Research 70 3: A completely randomized experimental design with three replicates for each fungicide strain and concentration was applied Fry, A linear regression with the OrigenPro software was carried out on the data, adjusting two types of curves sigmoid and exponential depending on the different strain responses to distinct active ingredients Fry, Four replicates were used.

This last clone was genetically similar to isolate AS Historically, sugarcane fields in this area have suffered more damage from this pest given the close proximity to pastures, and some sugarcane farmers have used M. Anthomyiidae in glasshouse and field experiments and effect of fungicides on fungal activity.

Tulloch M The genus Metarhizium. The presence of B. Five sampling points were located in each field, one at each corner and another at the centre. These results coincide with those reported by Chandler and Davidson who point out that iprodione is incompatible with M. The others were collected using the Galleria baiting method. Los resultados indicaron que los fungicidas benomyl y fenhexamid fueron compatibles con las cinco cepas, mientras que azoxystrobin y fludioxonil fueron incompatibles con todas las cepas evaluadas.

Pyralidae larvae baiting method was used to isolate M. The captured insects were transported to the laboratory in mL bottles with perforated tops to allow ventilation.

Intraspecific differentiation of Chilean isolates of the entomopathogenic fungi Metarhizium anisopliae var. One such alternative is Metarhizium anisopliae Metchnikoff Sorokin Moniliales: The plating procedure was carried out under sterile conditions in a laminar flow chamber.


Biological data analysis a practical approach. The molecular size of the fragments was estimated by comparison with a bp DNA ladder Entz et al. Fungal pathogenicity Mortality of M.

Applied and Environmental Microbiology Tierra Adentro Chile These results show that these insect pathogenic fungi have a flexible metabolism that includes the glyoxylate cycle as an integral part of germination, pathogenesis and saprobic growth. Sensitivity of populations of Botrytis cinerea from pear- related sources to benzimidazole and dicarboximide fungicides. When these mitotic asexual spores called conidia of the fungus come into contact with the body of an insect host, they germinate and the hyphae that anizopliae penetrate the cuticle.

The dendrogram indicated a genetic similarity between isolates CD and FC Sugarcane Saccharum officinarum L. Plagas de los berries en la zona centrosur. World Journal of Microbiology and Biotechnology Controle microbiano de insectos. aniwopliae

Addition of the ICL inhibitor anisoplae delayed conidial germination and inhibited appressorium formation. Retrieved from ” https: This inhibition probably generated a decrease in conidia germination and a decrease in germination tube length in those able to germinate, which in turn explains a decline in vegetative growth.

Therefore, there are cases where applying EF anissopliae prior to or follows the application of frequently used fungicides to control disease and which are registered for berries. The reaction mixture consisted of 0.
