Does the Ingestion of Isoxaflutole Herbicide Affect the Midgut and Salivary Glands of Pentatomidae Predators? Planta Daninha
GONÇALVES,T.S.; SOARES,M.A.; SANTOS,C.A.; SANTOS,D.A.; SANTOS,J.B.; BARROSO,G.A..
Podisus nigrispinus is a generalist predator naturally occurring in agricultural and forestry systems that effectively contributes to the population balance of phytophagous insects, especially defoliating caterpillars. Histological changes were evaluated in the salivary glands and midgut of P. nigrispinus caused by ingestion of systemic herbicide isoxaflutole. These predator females were fed with leaves of eucalyptus plants, Tenebrio molitor pupae or water, contaminated or not by herbicide. Salivary glands and midguts were dissected, processed and analyzed under a light microscope. Activity level and cell morphology of the salivary glands and midgut showed differences among insects fed on plants, contaminated water or pupae. The epithelia of the salivary...

Induction of drought tolerance by inoculation of Bacillus aryabhattai on sugarcane seedlings. Repositório Alice
MAY, A.; MOREIRA, B. R. de A.; MASCARIN, G. M.; VIANA, R. da S.; SANTOS, M. S. dos; SILVA, E. H. F. M.; RAMOS, N. P.; MELO, I. S. de.
Abstract: In twenty-first century, free-living endophytic and rhizosphere-competent microbes have become breakthrough strategies to meet global demands for sustainable foods and renewable fuelstocks owing to their great potential to produce stress-tolerant food and energy crops. Here, we investigate how Bacillus aryabhattai could mitigate water stress by drought in sugarcane seedlings. Briefly, the sugarcane genotypes, namely IAC91-1099 and RB85-5156, both exposed to cells-centrifuged B. aryabhattai suspension at 1x108 CFU mL-1 and non-treated were developed under irrigation regimes of 0, 7, 14 and 21 days to simulate different degrees of soil moisture content. The osmotolerant bacterium remarkably enhanced development of aboveground structures and root...
