Resumo: | The objective of this study was to evaluate the larvicidal activity of essential oil aqueous solutions (hydrolates) obtained by steam distillation of stalks and leaves of Croton argyrophylloides, Croton nepetaefolius, Croton sonderianus and Croton zehntneri against Aedes aegypti larvae. Twenty-five larvae of third instar were placed in plastic beckers, containing the hydrolates (50 mL), in a four repetitions scheme. Water was used as control and the number of dead larvae was counted after 24 hours. The data obtained were submitted to Variance Analysis and Tukey test. Significant differences were observed among the hydrolates from different species and from different parts of each plant (p < 0.001). The hydrolates of stalk and leaf from C. nepetaefolius and C. zehntneri and leaf hydrolate of C. argyrophylloides presented 100% mortality against larvae. The compounds present in C. zenhtneri and C. nepetaefolius are oxygenated phenylpropanoids that are more soluble in water than the monoterpenes and sesquiterpenes detected in the oils of C. argyrophylloides and C. sonderianus. This study showed that all species analyzed presented compounds with larvicidal properties, with differences between each plant parts. |

O objetivo deste trabalho foi avaliar a atividade larvicida dos hidrolatos obtidos por destilação à vapor de caule e folha das espécies de Croton argyrophylloides, Croton nepetaefolius, Croton sonderianus e Croton zehntneri contra Aedes aegypti. Em cada bioensaio foram utilizadas 25 larvas de 3º estádio juntamente com 50 mL de cada hidrolato, dispostos em recipientes plásticos, num esquema de quatro repetições, utilizando-se como controle a água e avaliando-se a mortalidade com 24 horas de tratamento. Os dados foram submetidos à análise de variância e ao teste de Tukey. Verificou-se que houve diferença significativa tanto em relação aos hidrolatos das diferentes espécies vegetais, quanto em relação às diferentes partes de cada planta (p < 0,001). Os hidrolatos referentes ao caule e folha de C. nepetaefolius e C. zehntneri causaram 100% de mortalidade das larvas e diferiram das demais espécies, exceto da folha do C. argyrophylloides que apresentou o mesmo resultado. Os compostos presentes em C. zehntneri e C. nepetaefolius são fenil propanóides mais solúveis em água que os monoterpenos e sesquiterpenos detectados em C. argyrophylloides e C. sonderianus. Esta pesquisa evidenciou que todas as espécies testadas possuem compostos com propriedades larvicidas, com diferenças entre as partes da planta analisadas. Universidade de São Paulo.
