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...

Effect of temperature on biology of Myzus persicae (Sulzer) (Hemiptera: Aphidid...
Barbosa, Leonardo Rodrigues; Carvalho, César Freire; Souza, Brigida; Auad, Alexander MachadoThe influence of constant and variable temperatures on biology of M. persicae in sweet pepper was evaluated. The nymphs were individualized on pepper leaf discs and maintained in Petri dishes at constant temperatures of 15, 20, 25, and 30ºC. In greenhouse the temperature was variable with an average of 24.9ºC and the nymphs were kept in appropriate cages and fixed in sweet pepper leaves. The experimental design...

Barbosa, Leonardo Rodrigues; Carvalho, César Freire; Souza, Brigida; Auad, Alexander MachadoThe influence of different densities of Myzus persicae (Sulzer) reared on sweet pepper leaves, Capsicum annuum L., was evaluated on biological aspects and on the predatory capacity of Chrysoperla externa (Hagen). The newly emerged larvae of predator were fed with aphid nymphs, offered in the densities of 50% below the average daily consumption, 50% above that consumption, and on sweet pepper foliar discs mainta...
Effect of female age and environmental factors on reproduction of the predator ...
Macedo, Luciano Pacelli Medeiros; Souza, Brigida; Carvalho, Cesar Freire; Ecole, Carvalho Carlos; Goussain, Marcio MarcosThe biotic and abiotic factors affect the reproductive potential of insects. Thus, the effects of female age and environmental factors on reproduction of Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) were studied. Adults of the predator were reared in "PVC" cages, closed in the upper portion with a thin mesh, organdie, placed on cotton plants at a greenhouse. The largest production of eggs by fema...
