Título:  From plant scent defense to biopesticide discovery: evaluation of toxicity and acetylcholinesterase docking properties for Lamiaceae monoterpenes.

Conteúdo:  Monoterpenes are a highly diverse group of chemical scents that originate from plant secondary metabolic processes, one purpose of which is to serve as a defense against herbivores. Plant-derived monoterpenes pro- duced from Lamiaceae species have demonstrated acaricidal activity against pest mites and ticks. However, the mechanism by which these compounds carry out the demise of this group of arachnids is poorly understood. Here, we review the chemistry and bioactivity of these promising compounds and subsequently assess their potential toxicity to mites and ticks through measurement of their docking ability to amino acid residues of the binding pocket of Drosophila melanogaster acetylcholinesterase (AChE). We identified 27 monoterpenes of the Lamiaceae family from the literature that were effective against mite (Varroidae, Tetranychidae, Eriophyidae) and tick (Ixodidae) species that are problematic in agricultural production. Screening of these compounds showed that monoterpenoids possessing methyl groups, such as carvacrol, linalool, ?-terpineol, bornyl acetate, and terpine-4-ol, strongly bind to D. melanogaster AChE. Linalool, which fits into the binding pocket in the amino acid catalytic triad of AChE (oxyanion hole residues, hydrogen bond interaction with GLU 237, and anionic binding with TRP 83), was identified as the most promising target for further optimization studies. We propose that monoterpenes which interact strongly with amino acid residues of the AChE recept... Mostrar Tudo

Título:  Water application efficiency of a microsprinkler irrigation system in banana crop.

Conteúdo:  The food production will be limited in a near future due to the shortening of water resources. The irrigated agriculture must seek for solutions in order to guarantee high yields using water with high efficiency. This work had as objective to determine deep percolation and application efficiency by using TDR technique in the water balance method for banana crop in a trickle irrigation system. The work was carried out at Embrapa Casava & Tropical fruits, Cruz das Almas city - Bahia State. Three different microsprinkler irrigation systems were evaluated: T1 - One 32 L h-¹-emitter per four plants (pseudostems) with one single lateral line per two crop rows; T2 - One 60 L h-¹-emitter per four plants (pseudostems) with one single lateral line per two crop rows and T3 - One 60 L h-¹-emitter per two plants (pseudostems) with one single lateral line per two crop rows. The irrigation systems that applies water at the soil with smaller variations of infiltrated water depths at all distances from the pseudostem are the more efficients. The water application efficiency for the systems with a 32 L h-¹ microsprinkler per four plants, 60 L h-1 microsprinkler per four plants and 60 L h-¹ microsprinkler per two were 85.01%, 79.72% e 89.54%, respectively.
