Item Efeito do óleo de pequi (Caryocar brasiliense Camb) obtido na feira livre de Princesa Isabel – PB, sobre Callosobruchus maculatus em feijão armazenado(2018) Lima, Edna Alves de; Silva, Renato Augusto da; http://lattes.cnpq.br/5111987334920733; http://lattes.cnpq.br/3607195370784211The Cowpea bean, Vigna unguiculata (Fabaceae), has an extraordinary role in feeding the population of the north and northeast regions of the country. However this culture is still detrimental to the loss of 10% of production due to the attack of insect-pests and use of synthetic chemical pesticides. In the present work the effect of the oil of Pequi (Caryocar brasiliense Camb.) As natural defensive, was studied on the dry rot (Callosobruchus maculatus) in Beanscowpea both acquired in the city of Princess Isabelle, Sertão of Paraíba. The methodology is very simple and can be reproduced in a domestic environment, because there is no need for the use of toxic substances, the oil of pequi used in cooking and alternative medicine. For the experiment it was used only of plastic containers, account drops and domestic balance, all low cost and commercially accessible. Concentration of 0.0 mg to 167.0 mg of oil per 20g of beans were analyzed and as a result was estimated the average lethal concentration (LC50) = 98.24 by means of linear regression. The good results presented here revealed that Pequi oil can be an economically viable and affordable alternative to the management of the rot in stored beancowpea beans.Item Extração do óleo fixo do Syagrus cearensis Noblick e atividade inseticida sobre o Callosobruchus maculatus em feijão armazenado(2019) Lemos, Cleide Maria de; Silva, Renato Augusto da; http://lattes.cnpq.br/5111987334920733The Cowpea bean, Vigna unguiculata, has an extraordinary role in feeding the population of the North and Northeast regions of the country. However, this crop is still harmed by the significant loss of production due to insect pest attack and poor product quality due to the use of synthetic chemical pesticides. In the present work the effect of the oil of the catolé Syagrus cearensis Noblick as natural defensive was studied on the carouscho Callosobruchus maculatus in cowpea, both purchased in the city of São José do Belmonte, sertão of Pernambuco. The methodology can be reproduced in domestic environment since the oil of catolé is used in cooking and folk medicine and there are no reports of intoxication. For the bio-insecticidal tests only plastic containers, syringes and household scales, all of low cost and commercially available, were used. The concentration of 0.0 mg to 123.2 mg of the oil per 20g of beans were analyzed and as a result the Lethal Concentration (LC50) = 64.96 was estimated using the "trend line" option of the Excel 2010 program, Office, Microsoft. The good results presented here, where there was 100% mortality of C. maculatus with the dosages of (88.0 mg and 123.2 mg), revealing that the catolé oil is an economically viable bioinseticide and accessible for the handling of the caruncho on stored cowpea beans.
