Estudio Cienciométrico de la producción científica publicada durante los años 2009-2021 para especies vegetales distribuidas en Colombia y Brasil con actividades Repelentes e Insecticidas

Abstract

This work describes the results of the scientometric study of the scientific production published during the years 2009-2021 for plant species distributed in Colombia and Brazil with repellent and insecticidal activities, through journals with an impact factor Q1-Q4 at the international level and others, with national categories A1-C for Colombia and Brazil. These publications were collected from databases such as Science Direct, Scielo, Springer Link, UNESP Institutional Repository, Dialnet, ACS publications, Taylor & Francis Online, Biblat, NCBI, colciencias repository (Minciencias), among others. The information was collected and recorded in a matrix, where scientometric indicators were established such as, number of publications of articles according to the country and year, species and plant organ studied, insect of interest, animal husbandry protocol and bioassay, extraction methodology plant and determination of the chemical composition, major secondary metabolites in the extracts and the biological activity reported together with its percentage. Based on scientometric indicators, it was possible to establish that 70% of the publications belong to studies of Brazilian plant species and the remaining 30% to Colombia, with Piper being the genus with the highest number of investigations; the most studied plant organ were the leaves with 182 investigations of the plant species exhibited in the 100 selected articles; the most frequent components in all the articles are α-pinene, β-pinene, limonene, 1,8-cineole, bicyclogermacrene, p-cymene, trans-β-caryophyllene, β-caryophyllene, germacrene-D, linalool, extracted and determined mainly by hydrodistillation and GC-MS; It is determined that few studies have performed tests on individual metabolites, however, in most cases, biological activity is attributed to the synergistic effect present in the components of the extract, sometimes with greater potential than the compound. synthetic used as a positive control; Additionally, the species of the insect class of greatest interest were Aedes Aegypti, Tribolium castaneum, Sitophilus zeamais and Bemisia tabaci, representing 36.8%, 11.4%, 8.8% and 3.5% respectively of the investigations; Within the bioassay and rearing protocols, it is found that the contact method was the most used and that feeding depended on the crops that attacked these insects, presenting variations according to their biological stage. In general, each bioassay presents an objective, an example of this, the biocidal bioassay, seeks the blocking of the binding sites to the Octopamine receptor, the inhibition of the Acetylcholinesterase enzyme e, interference in physiological activities until causing the death of the insect; on the other hand, the repellency, oviposition and antifeedant tests seek a behavioral modification of the insect; for these bioassays, there is mostly an extract dose-response relationship of the insect, dependent and dependent on the species. Taking into account the publications analyzed and the activities reported regarding their high repellent and biocide potential, the use of these plant extracts can be considered as an attractive natural alternative as a commercial product that promotes care for the environment and is an economical solution; effective and simple for the control of vectors of the insect class.
