O objetivo deste trabalho foi verificar a eficiência de inseticidas no tratamento de sementes no controle da cigarrinha-do-milho em viveiro telado. Sementes de milho foram tratadas ou não com inseticidas (imidacloprid, thiamethoxan, thiodicarb + zn, thiodicarb, carbofuran, carbofuran + zn e carbosulfan) e semeadas em vasos plásticos. Nas plantas, foram confinadas cigarrinhas sadias e avaliada a eficiência desses inseticidas no controle desse inseto, em diferentes intervalos de tempo e em períodos sucessivos. Os produtos imidacloprid e thiamethoxan foram os mais eficientes no controle da cigarrinha, proporcionando eficiência de controle de adultos de D. maidis igual ou superior a 70%, até o trigésimo dia de avaliação, após 4 a 24h de confinamento das cigarrinhas. |

Abstract: The formulation of diets that adequately meet energy requirements in the different phases of broiler chicken production is of the utmost importance. The objective of this study was to determine the optimal content of metabolizable energy (ME) for broiler chickens in various production phases using different statistical models. A total of 900 broiler chickens were assigned to 5 treatments with 9 replicates of 20 broiler chickens each from 21 to 42 d of age in a completely randomized design. Experimental diets were based on corn and soybean meal and formulated to meet the nutritional requirements of broiler chickens, except for ME requirements. Dietary treatments consisted of 5 pelleted/crushed diets with increasing levels of ME: T1 to T5 (2,850 to 3,250 kcal/kg), divided into grower (21 to 35 d) and finisher (35 to 42 d) phases. Feed intake (FI), body weight gain (BWG), feed conversion ratio (FCR), total energy intake, efficiency of energy use for BWG, and carcass and cuts yields were determined. The ideal ME content for best FCR was determined with the use of quadratic polynomial (QP), segmented, and linear response plateau models (LRP). In all evaluated periods, BWG was not influenced by ME, whereas FI and FCR decreased linearly with increasing ME. Total energy intake increased and the energy use efficiency for BWG decreased with greater ME (P < 0.05). Neither carcass nor cuts yields were influenced by dietary ME. The ideal dietary ME content differed between statistical models. In conclusion, based on FCR results, the QP regression model presented the best fit of the data in the grower phase, indicating an optimal content of metabolizable energy for feed conversion of 3,264 kcal/kg, whereas LRP presented the best data adjustment in the finisher phase, indicating 3,224 kcal/kg of ME as optimal.
