Hirsutella rhossiliensis and Verticillium chlamydosporium infected second-stage juveniles (J2) and eggs of Meloidogyne hapla, respectively, in petri dishes and in organic soil in pots planted to lettuce in the greenhouse. In vitro, H. rhossiliensis produced 78 to 124 spores/infected J2 of M. hapla. The number of J2 in roots of lettuce seedlings decreased exponentially with increasing numbers of...

Hirsutella thompsonii (Ht) is a fungal pathogen of acarines and the primary cause of epizootics among mites. The draft genomes of two isolates of Ht (MTCC 3556: Ht3, 34.6 Mb and MTCC 6686: Ht6, 34.7 Mb) are presented and compared with the genomes of Beauveria bassiana (Bb) ARSEF 2860 and Ophiocordyceps sinensis (Os) CO18. Comparative analysis of carbohydrate active enzymes, pathogen-host intera...

We report fungal pathogens of invertebrates (FPI) (Entomophthorales, Hypocreales, and Orbiliales) from roots an endemic Mexican pine, Pinus greggii Engelm. ex Parl., at four primary montane forests using next-generation sequencing. found twenty-nine OTUs 18 genera FPI associated to the P. greggii. New records for Mexico are: Beauveria felina (DC.) J.W.Carmich., Dactylella mammillata S.M. Dixon,...

The aim of the study was to determine effect temperature on growth four species acaropathogenic fungi genus Hirsutella (isolated from mites) grown in vitro Sabouraud (SDA) and Czapek-Dox media. effects seven ranges (5–35°C) were tested under laboratory conditions. Observations colony carried out every 5 days until day 25 by measuring diameter colonies mm. rate test isolates calculated mm per da...

Ribotoxins are fungal extracellular ribonucleases highly toxic due to their ability to enter host cells and their effective ribonucleolytic activity against the ribosome. The natural role of these proteins in the producing fungi is still unsolved. Nevertheless, recent studies showing the insecticidal properties of two ribotoxins from different origin support their involvement in defense mechani...
