Abstract

The objective of this work was to study the biology of predator Cycloneda sanguinea (L.,1763), having as prey aphids of genus Dactynotus sp. The observations were realized in the Entomo1ogy Laboratory of Phytosanitary Department - EA/UFG. The environmental conditions of temperature and relative humidity presented during the study period an average of 23°C and 79,4%, respectively. The coccinelideos were collected in field and packed in breeding cages. The studies were initiated with larvae originated from these insects layings. The hatching period of eggs was of 3 days with a viability of 86%. The 1arvae were observed every day, checking the biologic parameters as: larva period of 9.43 days, having each instar an average duration of 2.43, 1.57, 1.86 and 3.57 days, respectively for the 1st, 2nd, 3rd, and 4th instars. The period of pre-pupa and pupa were of 0.86 and 4.14 days, respectively. The biologic cycle from larva to adult was of 14.43 days. Larva as well as adults are predators. The larva consumption was an average of 14.6 aphids/day and consumption during all larva period was of 137.76 aphids. It was observed an increase in quantity of consumed aphids from the 1st to the 4th stages.
