Abstract: Pochoniachlamydosporia and Purpureocilliumlilacinum are fungal bioagents used for the sustainable management of plant parasitic nematodes. However, their production through submerged liquid fermentation and their use in seed treatment have been underexplored. Therefore, our goal was to assess the effect of different liquid media on the gr...
Abstract: This study evaluated the effects of potassium and sodium carbonate and bicarbonate, Bacillus subtilis (Cohn, 1872) QST-713, Bacillus pumilus (Meyer & Gottheil, 1901) QST-2808, and crude and roasted coffee oils on the inhibition of mycelial growth and conidial germination in Botrytis cinerea Pers.: Fr and the colonization of begonia (Begon...
Melanaphis sorghi (Theobald, 1904) is an invasive species recently introduced in the American continent and has been causing great losses in the sorghum crop. In surveys carried out in the cities of Uberlândia and Sete Lagoas, state of Minas Gerais, Brazil, during the year 2021, mummified specimens of M. sorghi were collected on sorghum plants, fro...
Este trabalho estimou o tempo de desenvolvimento médio da fase imatura (T_imaturos) e o número de gerações (NG) de Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) (DS), praga exótica de importância econômica no Brasil, considerando suas demandas térmicas em cinco municípios no período de um ano. A mesma estimativa foi realizada para o...
O presente estudo avaliou, em laboratório, a patogenicidade do nematoide Heterorhabditis bacteriophora HP88 sobre fêmeas de Rhipicephalus microplus com diferentes níveis de ingurgitamento (150, 200, 250, 300 e 350 mg), e sobre fêmeas provenientes de diferentes populações (1 a 8). / Evento online.
O uso de microrganismos com atividades antagônicas no controle biológico tem se tornado uma alternativa promissora contra doenças de plantas (1). Recentemente, bactérias do gênero Bacillus tem chamado a atenção na busca por novos agentes de biocontrole por serem microrganismos com capacidade de produzir uma ampla gama de compostos bioativos como pe...
Biological control is an environmentally safe alternative in the management of nematodes. The selection of new biocontrol agents has focused on the potential of Bacillus species in in vitro and in vivo studies. In this study, twenty-three local Bacillus isolates were characterised and evaluated for metabolisable carbon source, secondary metabolite ...
Melon is one of the most exported fruits from Brazil. The leafminer fly, Liriomyza sativae (Blanchard) (Diptera: Agromyzidae), is one of the major problems that negatively interfere in the productivity increase in this crop. Chemical control is the most adopted method for this pest; however, producers have reported reduced susceptibility to insecti...
The coconut mite, Aceria guerreronis Keifer, is one of the main pests of the coconut tree (Cocos nucifera L.) worldwide. Its control is mainly based on the use of acaricides. However, due to the habitat of this pest mite, which is protected by fruit bracts that act as a physical barrier, chemical control is often inefficient. Thus, natural enemies ...
