Ceratitis capitata (medfly) is a globally important horticultural pest that can be controlled using the sterile insect technique (SIT), but the success of SIT depends on the sexual performance of mass-reared males when released into the field. We added "guarana" (Paullinia cupana) powder (derived from an Amazonian fruit that is considered to be a stimulant with aphrodisiac effects, capable of improving human physical stamina) to the diets of adult male medflies to determine whether it increased their sexual performance. The basic diet of a protein extract + sucrose (1:3) was enriched with guarana powder (3 % on a volume basis). Experiments examining sexual competitiveness were performed using lab-reared males fed with the enriched diet vs.lab-reared males fed on the basic diet (and lab-reared females fed on the basic diet), as well as lab-reared males fed with the enriched diet vs. wild males fed on the basic diet (and wild females fed on the basic diet). The results of both experiments indicated that males maintained on diets enriched with guarana powder showed higher copulation successes than males fed only with the basic diet. Guarana powder therefore contributed to the greater mating success of lab-reared males (probably because of its stimulant properties), and may represent a new and viable option for increasing SIT effectiveness.
<p><strong>Objetivo:</strong> analisar as contribuições biotecnológicas empregadas ao combate do mosquito <em>Aedes aegypti</em> sob enfoque patentário. <strong> </strong> <strong>Metodologia:</strong> O software Questel-Orbit foi utilizado como banco de dados para prospecção das patentes empregando o termo “Aedes aegypti” como palavra-chave, a Classificação Internacional de Patentes (IPC) como filtro e biotecnologia como tecnologia dominante. <strong>Resultados e discussão: </strong>mostraram que o número de patentes biotecnológicas cresceu de forma significativa nos últimos vinte anos, sendo a grande maioria protegidas nos Estados unidos (US) e na Organização Mundial de Propriedade Intelectual (WO) pelo PCT. As seções mais frequentes no portfólio de patentes estão relacionadas às áreas de Química e Necessidades Humanas. <strong>Conclusão</strong>: Biotecnologia foi a principal tecnologia dominante empregada em todas as patentes. O crescimento significativo do número de depósitos de patentes evidenciados nos resultados acima demonstra o interesse das empresas e centros de pesquisa.</p><p class="MsoNormal" style="text-align: center;" align="center"><strong><span style="font-size: 14pt; font-family: 'Times New Roman', serif;">Contribuições biotecnológicas empregadas no combate do mosquito <em>Aedes aegypti</em>, sob enfoque patentário</span></strong></p>
The oil/gas, ethanol, biodiesel and biogas industries generate wastewater known as produced water, vinasse, crude glycerin and methanogenic digester´s based effluents, respectively. Microalgal systems have been suggested as a suitable and adaptable biological approach for the treatment of such wastewaters. The advantage of such an approach is the combination of treatment with the accumulation of algal valuable bioproducts. This systematic literature review aims to analyze scientific and patent production with bibliometric analysis. Another aim is to discuss the algal bioremediation strategies that were adopted by the cited industries for treating their distinct effluents. Data was obtained using scientific papers and patents published between 2000 to 2020 (335 scientific papers and 104 patents). The United States contributed with the largest number of articles, followed by China and Brazil. Meanwhile China, South Korea and the United States are the major owners of patents. This work identified that microalgal based system is successful in bioremediating several pollutants and that glycerol significantly improves algal performance for bioproducts production. Nonetheless, the efficiency of this process is hindered either by the adopted strategy applied before the cultivation stage or after this process. For instance, variables such as nutrient supplementation, turbidity and salinity corrections were identified as pivotal for process performance. Thus, the full-scale process is directly associated to the correct integration of wastewater production and proper management of microalgae systems.
