The insecticidal effect of the essential oil of Piper aduncum (EOPA), and of its constituent dillapiole [1-allyl-2,3-dimethoxy-4,5-(methylenedioxy) benzene] in particular, is well documented in the literature and can be associated with its interference with the enzymatic detoxification in arthropods. However, no data exist on the range of dillapiole content associated with insecticidal activity, which is necessary to establish reliable dose-activity parameters for a formulated product. The oil composition can also change during storage after distillation, mainly due to environmental factors such as light incidence, atmospheric oxygen and temperature, which can be deleterious to oil quality. In this study, EOPA subjected to different storage conditions over four years and its rectified fractions were submitted to bioassays to evaluate their insecticidal effect by topical contact and residual contact against Spodoptera frugiperda. Our objectives were to determine the relationship between dillapiole content and the insecticidal activity of EOPA, and to evaluate its chemical and toxicological properties over time under different conditions. Our results showed that EOPA was stable with respect to the dillapiole content and the toxicological effect against S. frugiperda under different storage conditions for four years. The overall chemical composition of the EOPA did not vary significantly among storage conditions. EOPA with dillapiole content ranging between 68% and 100% showed greater insecticidal toxicity by residual and topical contact against S. frugiperda larvae.
O efeito inseticida do óleo essencial de Piper aduncum (OEPA) e, particularmente, de seu constituinte dilapiol [1-alil-2,3-dimetoxi-4,5-(metilenodioxi) benzeno], está bem documentado na literatura e pode estar associado à sua interferência na desintoxicação enzimática em artrópodes. No entanto, não existem dados sobre a amplitude de teores de dilapiol associados à atividade inseticida, o que é necessário para estabelecer parâmetros de dose-atividade confiáveis para um produto formulado. A composição do óleo também pode sofrer alterações durante seu armazenamento após a destilação, principalmente devido a fatores ambientais como incidência de luz, oxigênio atmosférico e temperatura, que podem ser deletérios à qualidade do óleo. Neste estudo, durante quatro anos, OEPA submetido a diferentes condições de armazenamento e suas frações retificadas foram submetidos a bioensaios para avaliar seu efeito inseticida por contato tópico e contato residual contra Spodoptera frugiperda. Nossos objetivos foram determinar a relação entre o teor de dilapiol e a atividade inseticida do OEPA, e avaliar suas propriedades químicas e toxicológicas ao longo do tempo sob diferentes condições. Nossos resultados mostraram que o OEPA foi estável em relação ao teor de dilapiol e o efeito toxicológico contra S. frugiperda sob diferentes condições de armazenamento durante quatro anos. A composição química do OEPA não variou significativamente entre as condições de armazenamento. OEPA com teor de dilapiol entre 68% e 100% apresentou maior toxicidade inseticida por contato residual e tópico contra larvas de S. frugiperda.

Summary. The difference between the allelic expression of a gene is known as allele-specific expression (ASE), and it is a common event in mammal?s transcriptome. ASE is named genomic imprinting when guided by epigenetics mechanisms regarding the allele parental origin. Although these events are an important sources of phenotypic variation, knowledge thereof regarding cattle and effects on economically important traits are still incipient. Therefore, analysis and characterization of ASE profile in the muscle of adult Nelore animals were performed, and besides that, the ASE pattern and gene imprinting occurrence were checked in genes previously associated with meat tenderness. For this, RNA sequencing data of 146 Nelore steer muscles were used, and these animals were also genotyped for approximately 770,000 SNPs using Illumina BovineHD BeadChip. For each animal, a diploid genome was built based on their genotypes, and afterward, RNA-Seq reads were mapped to this genome. After counting the reads considering each SNP allele, a binomial test was applied to identify whether the allele contribution to total expression significantly diverged from 50%, followed by false discovery rate (FDR) test (0.05). Among 519 analyzed SNPs, 402 showed at least one sample with ASE, and they were spread among all autosomal chromosomes. SNPs showing ASE in more than five samples were tested regarding ASE extension, and most presented an incomplete pattern. Four ASE genes were previously identified in a Genome-Wide Association Study (GWAS) and five were found differentially expressed between extreme phenotype animals for meat tenderness. Therefore, the results will complement the bovine imprinted genes database, further they can provide new information to genetic effects prediction in animal breeding increasing the accuracy of meat tenderness selection.
