Selection of Bacillus thuringiensis strains toxic to cotton boll weevil (Anthonomus grandis, Coleoptera: Curculionidae) larvae = Selección de cepas de Bacillus thuringiensis tóxicas para larvas del picudo del algodonero (Anthonomus grandis, Coleoptera: Curculionidae)
(Asociación Argentina de Microbiología, 2017-09)Preliminary bioassays with whole cultures (WC) of 124 Bacillus thuringiensis strains were performed with neonate larvae of Anthonomus grandis, a major cotton pest in Argentina and other regions of the Americas. Three exotic ... -
Sex Chromosome Turnover in Moths of the Diverse Superfamily Gelechioidea
(Oxford University Press, 2019-04-08)Sex chromosomes play a central role in genetics of speciation and their turnover was suggested to promote divergence. Invertebrates, sex chromosome–autosome fusions resulting in neo-sex chromosomes occur frequently in male ... -
Signs of a phyllospheric lifestyle in the genome of the stress-tolerant strain Azospirillum brasilense Az19
(Elsevier, 2020-11)Azospirillum brasilense Az19 is a plant-beneficial bacterium capable of protecting plants from the negative effects of drought. The objective of this study was to determine and analyze the genomic sequence of strain Az19 ... -
Solid state culture conditions for improved conidial production of the mycoparasitic fungus Escovopsis weberi
(Taylor & Francis, 2023-11-15)We evaluated culture conditions (temperature, substrate moisture content, agitation and light conditions) for optimising conidia production of Escovopsis weberi Ew1 using solid state culture. In addition, several substrates ... -
Solid Substrate Production and Formulation of an Isolate of Metarhizium anisopliae for Biological Control of Stem Bug Tibraca limbativentris
(IDOSI Publications, 2014)One isolate of Metarhizium anisopliae (Ma 72) previously selected for its virulence against rice-stem bugs, Tibraca limbativentris, was studied. Its conidial production and quality parameters in several solid substrates, ... -
Soybean in rotation with cereals attenuates nitrous oxide emissions as compared with soybean monoculture in the Pampas region
(Elsevier, 2021-11)Nitrous oxide (N-N2O) emissions in the agricultural sector represent ca. 25% of total N-N2O emissions on a global scale. In Argentina, information on agricultural emissions is scarce, and thus, N-N2O emissions are estimated ... -
Species diversity of Cladorrhinum in Argentina and description of a new species, Cladorrhinum australe
(Springer, 2015-10)The genus Cladorrhinum constitutes a fungal group of prime importance for agriculture and livestock, since some species have biocontrol potential or were shown to promote plant growth and to produce phytases, which are ... -
Susceptibility of agricultural pests of regional importance in South America to a Bacillus thuringiensis Cry1Ia protein
(Elsevier, 2020-05)Bacillus thuringiensis toxins of the Cry1I class have dual specificity for insects in the orders Coleoptera and Lepidoptera. We assessed the toxicity of a Cry1Ia protein from an Argentinian B. thuringiensis strain against ... -
Talaromyces systylus, a new synnematous species from Argentinean semi-arid soil
(2016)The discovery of an interesting new synnematous Talaromyces species from Argentinean semi-arid soil has enlarged the number of synnema-producing species. Talaromyces systylus sp. nov. is characterized by the production of ... -
Temporal variation of physico-chemical, microbiological, and parasitological properties of poultry manure from two egg production systems
(Springer, 2020-03)Egg production has increased worldwide and, consequently, there is a large volume of poultry manure generated. The principal egg production systems are the caged ones, namely the conventional and the automated. The aim of ... -
The benefits of foliar inoculation with Azospirillum brasilense in soybean are explained by an auxin signaling model
(2018-09)Azospirillum sp. is one of the most studied genera of plant growth-promoting rhizobacteria (PGPR). The ability of Azospirillum sp. to promote plant growth has been associated with its ability to produce several phytohormones, ... -
