SUMMARY:

The Diaspis echinocacti scale (Bouché) (Hemiptera: Diaspididae), Ferrisia dasylirii (Cockerell) and Planococcus citri (Risso, 1813) (Hemiptera: Pseudococcidae), the first known as scale scale scale and the others as floury. Both groups of scale insects are important pests of several plants that are grown in the Northeast region. In addition to the injuries caused, due to feeding on host plants, such as decreased vigor, yellowing of the foliage and deformation and defoliation of the host plant, F. dasylirii and P. citri are important because they transmit viruses to plants. Ladybugs are widely used in the biological control of various pests such as aphids, whiteflies and blackflies, mealybugs and psyllids, lepidopteran eggs and mites. Among the species that occur in the Northeast is Zagreus bimaculosus (Mulsant) (Coleoptera: Coccinellidae), a native predator of D. echinocacti and also frequently found in areas infested with carmine cochineal. Therefore, this study aimed to compare the biological aspects of Z. bimaculosus fed on D. echinocacti and P. citri under laboratory conditions at a temperature of 25 ± 1 ° C, 70 ± 10% rh and 12-hour photophase. The results of comparative biology showed that Z. bimaculosus when fed with P. citri, had a shorter average time between the egg - adult phase, 50.01 days and when fed with D. echinocacti 53.49 days. In the other variables such as number of eggs, each female of Zagreus lays an average of 181.6 eggs and 105.1 new when fed with P. citri, the fertility is 70.63% for those fed with D. echinocacti is 48.7% when the food was P. citri, regarding adult longevity when fed with D. echinocacti males live 110.8 days and females 84.75 days. When the food is P. citri, males live 100.2 days and females 65.1 days.
