Atualmente existem no mercado inúmeras substâncias químicas empregadas controle de insetos-praga. Entre eles, os inseticidas são um grupo numeroso e destacado. Este trabalho teve como objetivo avaliar a compatibilidade “in vitro” entre Permetrina (Pounce®) Acefato (Orthene®) isolados UFMS 06 07 do fungo Metarhizium rileyi. Para tanto, o crescimento micelial, produção germinação dos esporos fora...

Cecropins are the most potent induced peptides to resist invading microorganisms. In the present study, two full length cDNA encoding cecropin2 (Px-cec2) and cecropin3 (Px-cec3) were obtained from P. xylostella by integrated analysis of genome and transcriptome data. qRT-PCR analysis revealed the high levels of transcripts of Px-cecs (Px-cec1, Px-cec2 and Px-cec3) in epidermis, fat body and hem...

Fungi of the Metarhizium genus are a very versatile model for understanding pathogenicity in insects and their symbiotic relationship with plants. To establish a co-transformation system for the transformation of multiple M. robertsii genes using Agrobacterium tumefaciens, we evaluated whether the antibiotic nourseothricin has the same marker selection efficiency as phosphinothricin using separ...
