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 ... -
Intersex and liver alterations induced by long-term sublethal exposure to 17α-ethinylestradiol in adult male Cnesterodon decemmaculatus (Pisces: Poeciliidae)
(2017)The aim of the present study was to assess the responses of the gonopodium morphology and the gonadal and liver histology of adult male Cnesterodon decemmaculatus to sublethal long-term exposure concentrations of ... -
Molecular identification of Azospirillum spp.: limitations of 16S rRNA and qualities of rpoD as genetic markers
(2017)Since their discovery, plant-growth promoting rhizobacteria from the genus Azospirillum have been sub-jected to intensive research due to their biotechnological potential as crop inoculants. Phylogeneticanalysis of ... -

Nuclear acridine orange fluorescence in Rhizoctonia isolates from rice
(2015-04-01)The genus Rhizoctonia DC (1805) has long been studied as an important soilborne pathogen that causes a wide variety of symptoms because it is a non-specialized pathogen3. Rhizoctonia sensu lato is characterized by the lack ... -
Inherited sterility in Tuta absoluta (Lepidoptera: Gelechiidae): Pest population suppression and potential for combined use with a generalist predator
(2016)Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of the most devastating pests of tomato. We studied whether partially sterile T. absoluta males and fully sterile females were capable of suppressing wild populations ... -
Light microscopy of microsporidian spores and baculovirus occlusion bodies in Epinotia aporema and Helicoverpa gelotopoeon larval tissues, respectively
(2016)Entomopathogens help regulate natural insect populations, and their use in pest management is the subject of active research. Classical and molecular techniques are currently available to elucidate disease etiology and ... -
