(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 ... -
Effect of the interaction between Anticarsia gemmatalis multiple nucleopolyhedrovirus and Epinotia aporema granulovirus, on A. gemmatalis (Lepidoptera: Noctuidae) larvae
(Elsevier, 2015-12)The bean shoot borer Epinotia aporema Wals. (Lepidoptera: Tortricidae) and the velvet bean caterpillar Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) are key pests of soybean and other legume crops in South America. ... -
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 ... -
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 ... -
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 ... -
