38. Efeito da adubação, coberturas vivas do solo e do controle na população de Corythaica cyathicollis (COSTA, 1864) (HEMIPTERA, TINGIDAE) em plantas de Solanum melongena (LINNEAUS, 1767) (SOLANACEAE) cultivadas em sistema convencional e orgânico. / Effect of the fertilization, soil lives coverings and of the control in the population of Corythaica cyathicollis (COSTA, 1864) (HEMIPTERA, TINGIDAE).in plants of Solanum melongena (LINNEAUS, 1767) (SOLANACEAE) cultivated in conventional and organic system
Solanum melongena L., eggplant, is a culture that has many problems, presenting itself as a hostess of diverse species of bacteria, fungi, mites and insects. The "chinch-bug", Corythaica cyathicollis (COSTA, 1864) is known to cause serious damage to the culture. The research was conducted at the Federal Rural University of Rio de Janeiro (UFRRJ) from August,
