Essential plant oils contain biopesticides that could be used to control many crop pests. Tetranychus spp. are mites that cause damage to several crops and are primarily controlled by synthetic pesticides. Literature showed that mites can be controlled with essential oils of plants containing eugenol. In this work, we evaluated the bioactivity of basil (Ocimum basicilum) accessions for peanut-spider mites control based on molecular, biochemical and agronomic assays. RNA from four basil accessions, previously chosen by divergence genetic analysis, were used to estimate the expression of eugenol synthase (EGS I) transcripts, by semiquantitative and polymerase chain reaction (qPCR) assays. Chromatography was, thereafter, performed in order to estimate the eugenol concentration. Feeding bioassays were performed using basil leaf extracts in order to estimate oviposition and mortality of spider mites females. Finally, a validation assay was carried out in greenhouse, using peanut plants previously infested with spider mites and weekly sprayed with basil water-extract. One basil accession, OVRS, revealed high phytotoxicity to spider mite females, at 15% water-extract. The mortality rate was 75% and complete inhibition of fecundity was found in BOD assays. In the greenhouse assay, the most severe damage due to mite infestations was found to plant height, number of pods and pod yield, which were reduced to 28, 53 and 52% in non-treated plants (control). Considering that basil is a short-cycle plant, with easy reproduction and management, these results represent an accessible alternative to organic control spider mites in peanut.

A formação e distribuição de raízes bem como o conteúdo de macronutrientes e AI foram estudadas em Ceiba pentandra e ViroIa surinamensis. As raízes foram separadas em raízes finas « 2 mm); casca e madeira das raízes grossas (> 2 mm) e casca e madeira da raiz pivotante. C. pentandra produziu 11,82 kg de biomassa seca de raízes, enquanto V. s'urinamensis 2,53 kg. Em C. pentandra estas distribuíram-se na seguinte ordem decrescente: madeira da raiz pivotante (6,66 kg); casca da raiz pivotante (2,98 kg); madeira da raiz grossa (1,49 kg); casca da raiz grossa (0,63 kg) e raiz fina (0,06 kq). enquanto em V. surinamensis a distribuição foi: madeira da raiz grossa (1,00 kg); madeira da raiz pivotante (0,82 kg); casca da raiz grossa (0,29 kg); raiz fina (0,25 kg) e casca da raiz pivotante (0,17 kg). Quanto aos elementos minerais, em C. pentandra os maiores acúmulos foram para: N nas raízes finas; K na casca e madeira das raízes grossas; Ca na casca e K na madeira da raiz pivotante. Em V. surinamensis estes foram promovidos por K nas raízes finas; AI na casca e K na madeira das raízes grossas; AI na casca e N na madeira da raiz pivotante. |
