“…The encapsulation has the purpose of increasing the viability of the oils by stabilizing the solution, protecting the molecules from environmental weathering, which can prolong their effect in field and/or greenhouse conditions (AZEVEDO et DELOS: Desarrollo Local Sostenible, Curitiba, v.16, n.42, p. 219-230, 2023jan. 2021VIEIRA;NEVES, 2019;CORREA et al, 2019). However, there are few studies that evaluate the efficiency of emulsifiers and encapsulating agents as stabilizers of bioinsecticides, since the application of encapsulants in the management of agricultural pests is very incipient, constituting a vast field to be explored.…”

Diaphania hyalinata, Plutella xylostella and Spodoptera eridania are considered important pests in vegetable crops, causing significant production losses. The most common method for managing these pests is the use of synthetic insecticides that cause chain damage, from human health to the environment. A less aggressive alternative is the use of botanical insecticides, such as essential oils, which present themselves as potential for the composition of bioinsecticides. In the present study, the efficiency of formulations based on d-limonene (major compound of the orange peel oil - Citrus sinensis) on the mortality of D. hyalinata, P. xylostella and S. eridania was evaluated. For this purpose, formulations containing d-limonene (2.0%), Tween 80 (0.05%) and water were prepared, combined with different encapsulating agents (xanthan gum, guar gum and maltodextrin) diluted to 2% (v /v). The formulations were sprayed on plants using a sprayer and five second-instar caterpillars were distributed on each plant. The mortality of caterpillars was evaluated 72 h after the application of the formulas. Formulation based on the compound d-limonene with the encapsulating agent guar gum had an effect on the mortality of P. xylostella and S. eridania and formulation with the encapsulating agent maltodextrin had an effect on the mortality of S. eridania.

Saberes tradicionais, etnobotânica e o ensino de ciências: estudo em escolas públicas do Maciço de Baturité, Ceará, Brasil

2019

O presente estudo objetivou compreender como os saberes tradicionais da Etnobotânica podem contribuir para o ensino-aprendizagem de Ciências. O estudo foi desenvolvido em duas escolas públicas de ensino fundamental II do Ceará. Caracteriza-se como uma pesquisa-ação de abordagem qualitativa. Os dados foram coletados no início do primeiro semestre de 2016, através da aplicação de um questionário com 50 discentes do 7º ano de duas escolas públicas. Após a interpretação dos dados, realizou-se uma oficina nas duas escolas, o que permitiu a troca de conhecimento e experiências entre os discentes. O estudo revelou que os estudantes possuem um amplo nível de informações acerca das plantas medicinais, porém esse conhecimento não é disseminado dentro do ambiente escolar, demonstrando a necessidade de valorização do conhecimento empírico dos discentes para promover uma aprendizagem contextualizada, fomentando a elaboração significativa do conhecimento.
