Planococcus citri (RISSO) (HEMIPTERA: PSEUDOCOCCIDAE): Male/female relationship...
Santa-Cecília, Lenira Viana Costa; Prado, Ernesto; Pereira, Andressa Barbosa; Souza, Brígida; Sales, LaraThe reproduction of the citrus mealybug, Planococcus citri (Hemiptera: Pseudococcidae) has been reported as biparental with facultative parthenogenesis or exclusively biparental. Parthenogenesis may be an attribute of local populations, thus geographic variations could be determinant for the type of reproduction. Therefore, this work aimed to increase our knowledge on the reproduction of P. citri by evaluating ...
Fertility life table of the planococcus citri (risso) and planococcus minor (ma...
Costa, Marlice Botelho; Souza, Brigida; Prado, Ernesto; Santa-Cecília, Lenira Viana CostaThe mealybugs Planococcus citri and Planococcus minor (Hemiptera: Pseudococcidae) have increased their importance in brazilian coffee and cause similar damage to plants. Our objective was to determine the characteristics related to the development of these species, testing the hypothesis that, despite of considered cryptic, they have different biological characteristics. Mealybugs crawlers were individually iso...

Evaluation of silicon on the probing behavior of the citrus mealybug [Planococc...
Santa-Cecília, Lenira Viana Costa; Prado, Ernesto; Morais, Jair Campos deSeveral researches focusing the use of silicon in plants have demonstrated an increase of plant resistance to stress and pests. This work aims to determine the effect of silicon, applied as calcium silicate (CaSiO3) on mealybug probing behavior by using the technique of Electrical Penetration Graphs (EPG). The citrus mealybug, [Planococcus citri (Pseudococcidae)], and coffee plants cvs. Catuaí and Catucaí were ...

Moraes, Jair Campos; Goussain, Márcio Marcos; Vilela, Michelle; Prado, ErnestoNo presente trabalho objetivou-se avaliar o efeito do silício e do inseticida dimetoato no comportamento de prova do pulgão-verde Schizaphis graminum (Rond.) (Hemiptera: Aphididae) em plantas de trigo. Os tratamentos foram: 1) silício no solo, 2) silício no solo + foliar, 3) silício via foliar, 4) silício no solo + aplicação de inseticida, 5) silício no solo + foliar e aplicação de inseticida, 6) silício via fo...
Effects of temperature in the development and survival of the mealybug Pseudoco...
Santa-Cecília, Lenira Viana Costa; Prado, Ernesto; Sousa, Marcella Viana de; Sousa, Ana Luiza Viana de; Correa, Lilian Roberta BatistaThe mealybug Pseudococcus longispinus (Targioni Tozzetti, 1867) (Hemiptera: Pseudococcidae) has been reported attacking coffee crops and causing fruit fall in the State of Minas Gerais, Brazil. The knowledge of its biology is necessary to implement control measures. Its development was studied at temperatures of 15, 20, 25, 30 and 35ºC. The insects were confined inside a Petri dish containing a foliar disc of 4...

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...
Mealybugs (Pseudococcidae) on coffee (Coffea arabica L.) in Minas Gerais State,...
Souza, Brígida; Santa-Cecília, Lenira Viana Costa; Prado, Ernesto; Souza, Júlio César deMealybugs can be found in roots and shoots of coffee trees, producing withering and damaging fruits. The correct identification of species is important to establish a biological control program and other management strategies. The aim of this study was to survey and identify mealybug species present in coffee, Coffea arabica L., in the state of Minas Gerais, Brazil. Samples were taken in some towns of the South...
