Abstract Background Bacillus thuringiensis ( Bt) is a widely used biopesticide. The bioinsecticide based on Bt obtained by fermentation, but the substrates currently for its production constitute ingredients of high commercial value. In this context, use agro-industrial residues as an alternative to make fermentation process viable large scale, in addition minimizing environmental problems and contributing destination these biotechnological purposes. Results first part study, previously...
The morphological traits of the female reproductive system Diaphorina citri were examined in detail. has telotrophic ovaries with ovarioles organized as a "bouquet", displaying rudimentary terminal filament and syncytial tropharium. vitellarium carries single growing oocyte at each maturation cycle, which is connected tropharium by nutritive cord. Morpho-functional changes occur during development, mainly mid to late vitellogenesis. Morphological events such patency follicular cells intense...
As many other insects with a restricted diet, the citrus psyllid Diaphorina citri Kuwayama, which vector causing agent of Huanglongbing, bacteria Candidatus Liberibacter spp., is intimately associated symbiotic microorganisms. These mutualist symbionts play key role on their host nutritional ecology, and are vertically transmitted to progeny. However, despite development reproduction, growing opportunities exploitation association insect-symbiont control insect vectored-pathogens, there very...
Abstract BACKGROUND Bacillus thuringiensis (Bt) is a Gram‐positive bacterium that synthesizes specific protein toxins, which can be exploited for control of various insect pests, including Diatraea saccharalis , lepidopteran severely damages sugarcane crops. Although studies have described the effects Bt in larval phases D. few examined its effect on eggs. Herein, we studied entomopathogenic potential serovar Aizawai GC‐91 (Bta) during embryo development with aim understanding mechanism and...
Global warming may impact biodiversity by disrupting biological interactions, including long-term insect-microbe mutualistic associations. Symbiont-mediated insect tolerance to high temperatures is an ecologically important trait that significantly influences insect's life history. Disruption of microbial symbionts are required insects would substantially their pest status. Diaphorina citri, a worldwide citrus pest, associated with the Candidatus Carsonella ruddii and Profftella armatura....
<title>Abstract</title> In this manuscript, we describe the effectiveness of crystal proteins from Gram-positive sporulating bacteria against <italic>Acanthamoeba castellanii</italic> trophozoites. Light and scanning electron microscopy were used initially to confirm presence in newly isolated soil bacteria. Toxicity tests conducted using 75 crystal-forming bacterial isolates <italic>A. The MA8, CAB7, AB5 displayed significant antiparasitic activity, with MA8 CAB7 showing IC50 values 4.1 4.3...
Embryonic development in Diatraea saccharalis F. (Lepidoptera: Crambidae) has been studied by means of whole mounts, histochemical techniques, and light microscopy. Three embryonic stages were identified up to larval eclosion. In the first stage, 0–10 h, intense multiplication energids occurred, significant changes RNA levels detected distinct zones before start blastulation. During second 10–24 new protein sites egg’s periphery. This was probably because migration formation blastula....
