“…In the sampled stalks, the total number of internodes per meter was counted and the total number of borer holes in each plot was also recorded. Each stalk was longitudinally separated, and the rot incidence was evaluated (Pannuti et al, 2013). The parameters observed were the total number of holes and number of internodes with red rot per meter of cultivation.…”

“…Research has shown that sugarcane yield is positively correlated with the availability of water and nitrogen (Pannuti et al, 2013;Thorburn et al, 2003). However, to achieve the maximum yields with nonlimiting water and nutrients, other factors must be effectively controlled, such as pests and diseases (Waclawovsky et al, 2010).…”

“…Recently, Pannuti et al (2013) reported a positive correlation between water and nitrogen availability and the incidence of and damage caused by the borer-rot complex in sugarcane. Although both factors (nitrogen fertilization and water availability) are known to affect the incidence of important pests (Schoonhoven et al, 2005), there are no studies reporting the effects of nitrogen fertilization in different water regimes on the borer-rot complex.…”

This study aimed to evaluate the effects of nitrogen availability in fertigation and rainfed management, as well as their interactions with the incidence of and damage caused by D. saccharalis and red rot in sugarcane. The experiment consisted of four treatments (0 and 150 kg ha -1 of N-fertilizer with irrigation; 0 and 150 kg ha -1 of N-fertilizer in rainfed management) in a randomized complete block design with four replications. The evaluated parameters were the number of holes and internodes with red rot per meter of cultivation, stalk yield and sugar content. In the laboratory (T = 25 ± 2 °C; R.H. = 70 ± 10%: 12:12-L:D), we evaluated the attractiveness and consumption of fragments of stalks from the different treatments for fourth instar larvae through choice and no-choice tests in a randomized complete block design with ten replications. Nitrogen fertilization via irrigation has favorable effects on borer-rot complex and leads to higher gains in stalk and sugar yields when compared to rainfed management. The increments of stalk and sugar yields due to nitrogen fertilization compensates for the increase in borer-rot complex infestation. In laboratory tests, D. saccharalis larvae were similarly attracted to all treatments regardless of the doses of N-fertilizer or the water regimes evaluated. However, fragments of sugarcane stalks produced with nitrogen fertilization were consumed more by D. saccharalis in both water regimes.

“…Apesar do conhecimento quanto ao benefício do uso da fertirrigação nitrogenada sobre a produtividade de cana-de-açúcar, alguns estudos mostraram que essa prática pode predispor o ataque de alguns insetos-praga, exigindo monitoramento constante (Pannuti et al, 2013). No entanto, faltam informações quanto ao efeito da disponibilidade hídrica e de nitrogênio na incidência de M. fimbriolata.…”

ABSTRACT:Brazil stands out as the world's largest producer of sugarcane and its productivity is closely related to the availability of water and nitrogen during its development and also to the incidence of pest insects. Among the species most harmful to the sugarcane in Brazil, Mahanarva fimbriolata stands out, which has seriously endangered the yields. In this context, the present study aimed to evaluate the effect of the nitrogen fertirrigation on the incidence and damage caused by M. fimbriolata in sugarcane. The experiment was composed of five treatments and four replications in a randomized block design (RBD). The treatments were composed of four doses of N-fertilizer and control (0, 50, 100, 150, 200 kg.ha -1 ) in drip irrigation system. The parameters evaluated were: number of nymphs in the roots, stalk productivity, sugar content, percentage of sugar, total recoverable sugar and the agricultural contribution margin. It was observed that the fertirrigation increases the productivity of stalks and sugar with the increase of nitrogen fertilization by irrigation. The use of 200 kg.ha -1 of N-fertilizer increased the incidence of M. fimbriolata up to the control and economic damage levels. The biggest financial yield was obtained with the dose of 150 kg.ha -1 of N-fertilizer.KEYWORDS: Saccharum sp.; spittlebug; irrigation; nitrogen. RESUMO:O Brasil se destaca como o maior produtor mundial de cana-de-açúcar e sua produtividade está intimamente relacionada à disponibilidade de água e nitrogênio durante seu desenvolvimento e também à incidência de insetos-praga. Dentre as espécies mais nocivas à cana-de-açúcar no Brasil, destaca-se Mahanarva fimbriolata, a qual tem comprometido seriamente sua produtividade. Nesse contexto, o presente trabalho teve como objetivo avaliar o efeito da fertirrigação nitrogenada sobre a incidência e os danos ocasionados por M. fimbriolata em cana-de-açúcar. O experimento foi composto por cinco tratamentos e quatro repetições em delineamento de blocos casualizados (DBC). Os tratamentos foram constituídos por quatro doses de N-fertilizante e controle (0, 50, 100, 150 e 200 kg.ha -1 ) em sistema de irrigação por gotejamento. Os parâmetros avaliados foram: número de ninfas nas raízes, produtividade de colmos (TCH), produtividade de açúcar (TPH), açúcar total recuperável (ATR), pol de cana corrigido (PCC) e margem de contribuição agrícola. Foi observado que a produtividade de colmos e de açúcar aumentou com a adubação nitrogenada por meio da irrigação. O uso de 200 kg.ha -1 de N-fertilizante elevou a incidência de M. fimbriolata até os níveis de controle e dano econômico. O maior rendimento financeiro foi obtido com a dose de 150 kg.ha -1 de N-fertilizante. PALAVRAS-CHAVE:Saccharum sp.; cigarrinha-das-raízes; irrigação; nitrogênio.
