Summary in the original language of the document
Testes para avaliar o consumo foliar de batata submetida a diferentes tinturas de Meliáceas e óleo de nim por adultos de Diabrotica speciosa (Ger.) foram conduzidos no Laboratório de Entomologia da Embrapa Clima Temperado, Pelotas, Brasil. Discos foliares de plantas de batata, cultivadas em vaso, foram utilizados nos testes com e sem chance de escolha. No teste sem chance de escolha cada placa de Petri (90 mm) contendo um disco de determinado tratamento recebeu um casal de adultos, no teste com chance de escolha cada placa de Petri (140 mm) contendo um disco de cada tratamento recebeu três casais de adultos. Utilizaram-se a mesma metodologia para os ensaios com óleo de nim. Os produtos a base de Trichilia claussenii C. DC. nas concentrações de 10 e 20% obtiveram as menores áreas consumidas no teste sem chance de escolha. No ensaio com chance de escolha as menores áreas consumidas foram nos tratamento com T. claussenii e Cedrela fissilis L. No ensaio sem chance de escolha com óleo de nim, nenhum tratamento se diferenciou da testemunha com água. No ensaio com chance de escolha todos os tratamentos obtiveram valores de consumo menores do que a testemunha.
Summary translation
Tests were carried out to evaluate the foliar consumption of potato under different dyes of meliáceas and neem oil by Diabrotica speciosa (Ger.) were conducted in Entomologic Laboratory at Embrapa Clima Temperado, Pelotas, Brazil. Leaf discs from potato plants, grown in pots, were used in tests with and without choice. For the essay with meliáceas, in the no-choice test Petri dish (90 mm) containing a disk of determined handling received a couple of adults, in the free-choice test Petri dish (140 mm) containing a disk of each treatment received three couples of adults. They utilized the same methodology for the neem oil essay. The products of Trichilia claussenii C. DC. in the concentrations of 10 and 20% had the smaller areas consumed in the free-chance test. In the no-choice essay the smaller areas consumed were in treatment with T. claussenii and Cedrela fissilis L. In the free-choice essay with neem oil, no treatment was differentiated of the water control. In the free-choice essay all of the treatments had smaller values of consumption than the control.
