Bacillus thuringiensis and their endophytic capabilities
(2017-07)The main characteristic of Bacillus thuringiensis is that during sporulation produces a parasporal inclusion formed by one or more proteinaceous bodies that exhibit insecticidal activity upon ingestion by susceptible ... -
In vitro PGPR properties and osmotic tolerance of different Azospirillum native strains and their effects on growth of maize under drought stress
(2017-09)Osmotic variations in the soil can affect bacterial growth diminishing the number of inoculated bacteria. In a scenario of water deficit having tolerant bacteria would be beneficial to achieve a better response of the plant ... -
Characterization of Fusarium graminearum isolates recovered from wheat samples from Argentina by Fourier transform infrared spectroscopy : phenotypic diversity and detection of specific markers of aggressiveness
(2017-03)Fusarium graminearum is the primary causal agent of Fusarium head blight of wheat in Argentina. This disease affects crop yields and grain quality also reducing the wheat end-use, and causing mycotoxin contamination. The ... -
Characterization of a new Helicoverpa armigera nucleopolyhedrovirus variant causing epizootic on a previously unreported host, Helicoverpa gelotopoeon (Lepidoptera: Noctuidae)
(2016)This paper reports the first biological and molecular characterization of a nucleopolyhedrovirus isolated from the soybean and cotton pest Helicoverpa gelotopoeon. Studies were performed following a virus outbreak in a ... -
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 ... -
Assessing the specificity of a herbivore on a plant of uncertain phylogenetic placing: Listronotus elongatus a herbivore of Hydrocotyle ranunculoides
(2017)Hydrocotyle ranunculoides (Araliaceae) is an aquatic plant native to the Americas and invasive in Europe. This work reports laboratory and garden studies on the host range of its main natural enemy, the weevil Listronotus ... -
Discrimination of infested cotton squares by females of Anthonomus grandis
(2017)The avoidance of infested squares of Gossypium hirsutum as oviposition substrate by females of Anthonomus grandis was studied following two approaches. First, the preference for oviposition in infested versus non-infested ... -
Genotoxic effects induced by Cd+2, Cr+6, Cu+2 in the Gill and Liver of Odontesthes bonariensis (Piscies, Atherinopsidae)
(2016)Genotoxic effects of Cd?2, Cr?6, and Cu?2 on the gill and liver of the Argentinean Silverside (Odontesthes bonariensis) were studied using the comet assay and in relation with the metal tissue accumulation. Fish were exposed ... -
Development of phytotoxicity indexes and their correlation with ecotoxicological, stability and physicochemical parameters during passive composting of poultry manure
(2016-08)Both raw and composted poultry manure is applied as soil amendment. The aims of this study were: (1) to develop phytotoxicity indexes for organic wastes and composts, and (2) to assess the correlation among phytotoxicity ... -
Acceptability and suitability of Tuta absoluta eggs from irradiated parents to parasitism by Trichogramma nerudai and Trichogramma pretiosum (Hymenoptera: Trichogrammatidae)
(2016)Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of the most devastatingpests of tomato crops. We studied the acceptability and suitability of eggs laid byirradiated T. absoluta pairs to parasitism by the parasitoids ... -
