Agronomic performance of lettuce cultivars in aquaponics
Mendes, Fábio Teixeira de Carvalho; Freitas, Aurivan Soares de; Alcantra, Eliana; Marques, Rosângela Francisca de Paula VitorLettuce is a vegetable that can be produced in different cultivation systems, such as aquaponics. The objective of this work was to evaluate the performance of lettuce cultivars from the purple, american, smooth and curly lettuce groups in aquaponics. The system consisted of an area of approximately 10 m3, consisting of a 1 m3 fish breeding tank, a 240 L settling filter, a 240 L biological filter and nine 3 m l...
Levantamento e identificação de Collembola em área de cultivo de Persea america...
Souza, Thayne Marilis de; Medeiros, Larissa Lúcio da Mota; Alcantra, Eliana; Oliveira, Alisson Souza de; Marques, Rosângela Francisca de Paula VitorABSTRACT: Organisms like Collembola are indicators of soil quality and act as decomposers that promote litter fragmentation, improve soil structure and aeration. This work aimed to carry out the survey and identification of Collembola in an area with avocado cultivation. The collections were performed using Pitfall traps in an avocado growing area, from April to July. In total, six biweekly field collections we...
Resistência induzida ao pulgão-do-algodoeiro em cultivares de algodão colorido
Alcantra, Eliana; Moraes, Jair Campos; Auad, Alexander Machado; Silva, Alex Antônio; Alvarenga, RobertaObjetivou-se avaliar a resistência de cultivares de algodão colorido por meio de indutores químicos. Diferentes cultivares de algodão foram plantados em vasos e mantidas em sala climatizada (temperatura diurna de 28±2oC e noturna de 25±2oC; 70±10 % de U.R. e 12 horas de fotofase). Ácido silícico ou acibenzolar-S-methyl foram aplicados nas plantas e estas foram ofertadas para o afídeo Aphis gossypii. O delineame...

Santa-Cecília, Lenira Viana Costa; Correa, Lílian Roberta Batista; Souza, Brígida; Prado, Ernesto; Alcantra, ElianaThe citrus mealybug Planococcus citri (Risso, 1813) feeds mainly on flowers and fruits of coffee plants from blooming until harvest. Little is known about its development in coffee although its occurrence is already known for several years. This work aims to study the nymph development of this mealybug in coffee plants. Eggs were isolated from a stock culture kept in laboratory and placed inside Petri dishes co...
Biological aspects of Chrysoperla externa (Hagen) preying on Oligonychus ilicis...
Neto, Marçal Pedro; Carvalho, César Freire; Reis, Paulo Rebelles; Santa-Cecília, Lenira Viana Costa; Souza, Brígida; Alcantra, ElianaThe red mite Oligonychus ilicis (McGregor, 1917) and the mealybug Planococcus citri (Risso, 1813) are considered important pests of the coffee plant (Coffea arabica L.), causing yield losses. The predator Chrysoperla externa (Hagen, 1861) is associated with those pests. The objective of this work was to evaluate the development of the immature and adult phases of the predator fed, in the immature phase, on thos...
