Meta-análisis sobre el conocimiento científico publicado acerca de procesos de extracción y formulación de bioinsecticidas provenientes de plantas neotropicales.

Abstract

This investigation aims to make a meta -analysis about scientific knowledge published about the processes of extraction and formulation of bio insecticides coming from the neotropical plants by means the available information in important data basis national and international, so that quantity and quality of current situation of this knowledge area can be determined. About 120 reference works focused on the control of insects by botanic extracts were found. From the total, 60 were excluded because they are not indexed identifying only publications about indexed magazines. We could found 60 articles of different virtual sources (national and international) but we investigated about 33 articles corresponding to evaluation with extraction process. The publications showed comparative data of the botanic efficiency in field and laboratory. The insects are changing every day and they are resistant to the synthetic pesticide application. This is very worrying around the world because the crops are reaching a high point of tolerance against the pesticides. A systematic revision was applied as a one of the protocols for the application of meta-analysis, for the studies of extraction processes and extracts that are used in the studies to control the plagues and a meta-analysis to synthetize the comments about methods and processes of botanic extracts to control insects. The results in the forest plot diagram show that the method of extraction used by the investigators is effective to control pets. The meta analysis about extraction processes and formulation of bio insecticides coming from neotropical plants let us show that a right process of botanic extraction increases the probability or risk that the pest insect die compared with the control. We should know theory and protocols of the meta-analysis to carry it out.
