Abstract: The eucalyptus snout beetle (ESB), Gonipterus platensis, is endemic to Australia but has become a major invasive, destructive pest of Brazilian eucalyptus plantations. Efforts to develop insecticides based on entomopathogenic fungi against ESB are limited by the lack of known virulent strains. We therefore explored the virulence of indige...
Abstract: Microsporidia are naturally occurring fungal-related parasites that can infect nearly all animal hosts, but their biocontrol potential of insect pests is routinely overlooked in agriculture and forestry. This research brings the first report describing the natural occurrence of a microsporidium causing disease in field-collected populatio...
Abstract: Culturing the entomopathogenic fungus, Beauveria bassiana, under high glucose concentrations coupled with high aeration results in a fungal developmental shift from hyphal growth to mostly blastospores (yeast-like cells). The underlying molecular mechanisms involved in this shift remain elusive. A systematic transcriptome analysis of the ...
O objetivo deste trabalho foi avaliar a patogenicidade de diferentes fungos entomopatogênicos a adultos do bicudo-do-algodoeiro, Anthonomus grandis, e a ninfas de segundo ínstar do percevejo-marrom, Euschistus heros. / bitstream/item/224259/1/jt-p75.pdf
Abstract: The tick Rhipicephalus microplus poses a serious threat to the cattle industry, resulting in economic losses aggravated by tick resistance to chemical acaricides. Strains of Metarhizium spp., a well-known group of entomopathogenic fungi, can contribute to managing this ectoparasite. We explored two novel granular, microsclerotia- or blast...
Abastract: The interaction between Metarhizium spp. and plant roots may induce host plant growth and help control below- and above-ground pests and diseases. We conducted in vivo and in vitro bioassays using native Brazilian isolates of Metarhizium robertsii (ESALQ 1635), M. humberi (ESALQ 1638), and M. anisopliae (ESALQ 1669) to better understand ...
O objetivo deste trabalho foi avaliar a patogenicidade de diferentes fungos entomopatogênicos a adultos do bicudo-do-algodoeiro Anthonomus grandis Boheman, 1843 (Coleoptera: Curculionidae). / bitstream/item/207414/1/35686.pdf
O objetivo deste trabalho foi determinar a temperatura mínima, ótima e máxima para o crescimento e esporulação de Beauveria bassiana, Cordyceps javanica e Metarhizium anisopliae. / bitstream/item/207412/1/35685.pdf
O objetivo desse trabalho foi avaliar o efeito do metilparabeno (Nipagin®), um composto antifúngico que pode ser adicionado às dietas de criação massal, na sobrevivência de machos tsl Vienna-8 e na eficiência de transferência horizontal à fêmeas de C. capitata. / bitstream/item/205730/1/Aumentando-a-tolerancia-de-machos-estereis-de-Ceratitis-capita...
