Aims: Evaluate the insecticidal effect of the aqueous extract of neem leaves on the control of Costalimaita ferruginea in eucalyptus. Place and Duration of Study: Entomology Laboratory of the Center for Agricultural Sciences (CCA) of the State University of the Tocantina Region of Maranhão (UEMASUL) between November 2016 and July 2017. Methodology: Neem aqueous extract solutions were tested at concentrations of 40, 60 and 80%, and the control group treated with mineral water. Leaves of eucalyptus seedlings were immersed in each concentration and individualized in Petri dishes together with the insects. The design was completely randomized with four treatments and ten repetitions, each repetition consisting of a Petri dish with an insect and a eucalyptus leaf. The evaluations were carried out daily, analyzing the mortality of adults, and the leaves were replaced by others submitted to the same treatment and procedure described above. Results: In the evaluations of 12, 60, 72 and 84 hours there was no significant difference. 36 hours after the implementation of the experiment, the 60% neem concentration resulted in 100% mortality of specimens. Conclusion: The 60% neem concentration is the most efficient due to its rapid effect on C. ferruginea mortality and economy of raw material for production.

ResumoO objetivo deste estudo foi selecionar artigos de dois produtos naturais própolis e Aroeira (Myracrodruon urundeuva), que apresentassem ação anti-inflamatória na odontologia. Acessou-se a base de dados PubMed, entre os meses AbstractThis study's aim was select Aroeira (Myracrodruon urundeuva) and propolis natural products articles that submit anti-inflammatory action in dentistry. Accessed the PubMed data base in 2015 Abril to August months. The descriptors used in the search were "Anti-Inflammatory AND Propolis" AND "Anti-Inflammatory AND M. urundeuva", without language, articles publication year or type limits established, but only the studies with natural products with application in anti-inflammatory activity in dentistry were selected. 207 articles were obtained, and after the thorough analyze realized for two evaluators, 193 were excluded, once 154 weren't suitable to the

The açaí berry processing activity generates a large amount of waste that is a problem in several cities, mainly in the Amazon region of Brazil, due to the large production of açaí juice. This study aimed to reuse the waste from açaí berry’s processing as a substrate in the production of aroeira native seedlings, studying the effects of its application and evaluating the morphological parameters results. The experiment was carried out in the greenhouse in the city of Imperatriz - MA, with waste collection carried out in 2015. After collection, part of the waste was charred and transformed into the substrate through grinding and sieving. Subsequently, the substrates were mixed with the local soil in different proportions. Thus, the 9 treatments were obtained. To test the substrate the native aroeira species was used. The effects of different treatments were evaluated 15, 30, 45 and 60 days after germination, by plant height (H), neck diameter (ND) and leaf number (NL). The results showed that the use of this residue is not promising as a substrate because they do not have good performances for the parameters evaluated in the seedlings.
