Cold storage of Trichogramma nerudai using an acclimation period
(Springer, 2018)The availability of suitable storage methods for parasitoids is a valuable tool in biological control programs. Studies were conducted to investigate the effects of cold storage with acclimation period on the quality of ... -
Biological and molecular features of Nosema rachiplusiae sp. n., a microsporidium isolated from the neotropical moth Rachiplusia nu (Guenée) (Lepidoptera: Noctuidae)
(Springer, 2018-05)Light, electron microscopy and DNA analyses were performed to characterize a microsporidium infecting Rachiplusia nu larvae from a laboratory rearing in Argentina. Diplokaryotic spores were oval and measured 3.61 ± 0.29 ... -
Direct effect of ozone pollution on aphids: revisiting the evidence at individual and population scales
(2015-04)Most of our knowledge about the consequences of tropospheric ozone pollution on aphid–plant interaction assumes the absence of a direct effect of ozone on aphids. However, the biological effects of ozone encompass changes ... -
Prospection and molecular analysis of CpGV isolates infecting Cydia pomonella at different geographical locations in Argentina
(2015-01)The occurrence and genetic diversity of Cydia pomonella granulovirus infecting C. pomonella across Argentina were investigated. Larvae were collected from fruit orchards in regions where CpGV‐based biopesticides have been ... -
Natural occurrence of the entomopathogenic genus Pandora on spittlebug pests of crops and pastures in Argentina
(2018-04)The natural occurrence of entomophathogenic fungi infecting spittlebugs (Hemiptera: Cercopidae) considered serious pests to pasture grasses and crops in Argentina was investigated during summer˗autumn (December to May) ... -
Evaluation of compost of swine waste as amendment for production of cut wallflowers (Matthiolaincana)
(2018-02)The intensification of swine production systems generates accumulation of manure, which if not stabilized can generate negative impact on the environment. At the same time, the demand for organic materials to amend the ... -
Removal of organic matter and nutrients from a porcine effluent, through geo-containment filtration
(2018-01)The intensive porcine productions generate effluents with high contents of solids, organic matter, phosphorus and nitrogen; constituting a source of contamination when they are not treated accordingly. Geocontainment ... -
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, ... -
