Abstract: O objetivo deste trabalho foi avaliar o efeito de inseticidas no controle da mosca-branca (Bemisia argentifolii Bellows & Perring, 1994) na incidência do vírus-do-mosaico-dourado e na produtividade do feijoeiro. Utilizou-se de tratamento de sementes com imidacloprid ou thiamethoxam, e de pulveriza es de inseticidas, em intervalos semanais. O experimento foi realizado no campo, em área irrigada, em Petrolina, PE, em blocos ao acaso, com cinco tratamentos e quatro repeti es. Houve redu o significativa no número médio de ovos, de ninfas e de adultos da mosca-branca e na porcentagem de infec o pelo vírus-do-mosaico-dourado do feijoeiro. A produtividade nas parcelas tratadas variou de 1.930 a 2.405 kg/ha, enquanto na testemunha foi de 1.490 kg/ha. N o foi observada diferen a significativa entre os tratamentos, no número de vagens/planta e peso de 100 sementes.

Abstract: Diabetes mellitus is a disease characterized by the excess of sugar in the blood and urine. The two most common types of diabetes are insulin-dependent diabetes mellitus and insulin-resistant diabetes mellitus, both presenting glycemic regulation-damage caused by insulin. Nevertheless, there is another type of diabetes that is less known but not less important, the diabetes insipidus, which is characterized by a problem with the synthesis, secretion or action of the ADH (anti-diuretic hormone) that can result in polyuric syndromes with increased excretion of hypotonic urine. Physiologically, variations in the osmotic pressure activate osmoceptors that stimulate the ADH secretion, increasing water reabsorption in the kidney collection tubes. This article intends to revise a wide-ranging study on diabetes insipidus, aiming at a comparative analysis of the incidence, diagnosis, causes, types, treatment and consequences between diabetes insidipus and diabetes mellitus. Diabetes mellitus and insipidus are two different pathologies with a single similarity that is the diabetes itself, that is, the polyuria established. The knowledge of the significant differences between the pathologies studied is important once diabetes insipidus is less known, but can lead to serious complications if not properly treated. O diabetes mellitus é uma doen a caracterizada pelo excesso de a úcar no sangue e na urina. Os dois tipos mais comuns de diabetes s o diabetes mellitus insulino-dependente e diabetes mellitus insulino – resistente, e que ambos apresentam comprometimento da regula o da glicemia por a o da insulina. No entanto, existe outra forma de diabetes menos conhecida, mas n o menos importante, o diabetes insipidus, que é caracterizado por um distúrbio na síntese, secre o ou a o do ADH (horm nio antidiurético), que pode resultar em síndromes poliúricas com excre o aumentada de urina hipot nica. Fisiologicamente, varia es na press o osmótica ativam osmorreceptores que estimulam a secre o do ADH e esse aumenta a reabsor o de água nos túbulos coletores renais. O presente artigo prop e revisar um estudo abrangente do diabetes insipidus, visando a uma análise comparativa da incidência, diagnóstico, causas, tipos, tratamento e conseqüências entre diabetes insipidus e diabetes mellitus. Diabetes mellitus e insipidus s o duas patologias diferentes com a única semelhan a que é o próprio diabetes, isto é, poliúria estabelecida. O conhecimento das significativas diferen as entre as patologias estudadas é importante, uma vez que o diabetes insipidus é menos conhecido, poré

Abstract: Na busca de alternativas ao controle químico do caruncho Zabrotes subfasciatus (Coleoptera:Bruchidae), avaliou-se, em feijoeiro (Phaseolus vulgaris L.), o efeito de três genótipos, cv. Carioca e duas linhagens contendo a proteína arcelina (Arc1 e Arc3), e da adi o nos gr os armazenados de óleo de soja (Glycine max Merrill); óleo de nim (Azadirachta indica A. Juss.), munha (resíduo de trilha da colheita), calcário dolomítico e terra de formigueiro, comparativamente aos gr os n o tratados e ao controle químico com malathion 500 CE. O experimento foi realizado no laboratório da Embrapa-Centro Nacional de Pesquisa de Arroz e Feij o, localizado no Município de Santo Ant nio de Goiás, GO, em condi es n o controladas. Na linhagem Arc1, constatou-se maior prote o aos danos do caruncho, observando-se redu o do número de ovos e de adultos emergidos e da porcentagem de sementes danificadas em rela o à Arc3 e à cv. Carioca. Quando os gr os foram tratados com malathion, óleo de nim e óleo de soja, observou-se menor número de ovos e de adultos emergidos e redu o de danos, e n o houve diferen a na porcentagem de sementes danificadas entre o malathion e o óleo de nim. A mistura das sementes com terra de formigueiro conferiu baixa prote o ao caruncho, enquanto os tratamentos com munha e calcário dolomítico n o apresentaram eficiência na redu o da progênie e dos danos de Z. subfasciatus.
