| Seven nests of T. fuscus Emery, 1834 have been studied for their structure. These nests, which opened at the soil surface, had two to four chambers located one above the other. Externally all of these nests presented a heap of brownish-yellow debris that was constituted basically by remains of vegetable material. The total nest population was, on average, 1,048 individuais. The diel pattern of foraging of this species was studied for four consecuti ve months on two nests. This activity occurred predominantly in the night period, and the workers transported, mainly, dry vegetation to the nest. |

| While population foraging behaviour of herbivores has been extensively studied, individual choice is still poorly understood. Very few studies have focused on the individual consistency of foraging behaviour in marine herbivores. Because marine ectotherms are strongly influenced by their environment and because a mixed diet is appropriate for herbivores, we hypothesized that Haliotis tuberculata, a large marine gastropod, would not exhibit significant individual consistency in foraging activity and would display generalist food choices. To test these hypotheses, the behaviour of 120 abalone was studied using a choice test of eight macroalgal species over 3 weeks, with video recording 24 hr a day. In addition, primary components, secondary metabolites and... |

| ABSTRACT: The main of this research was to report an atypical foraging behavior in a colony of Trachymyrmex fuscus, situated in "Cerrado" (savanna ecoregion of Goiás, Brazil). The colony foraging activity was performed only by sexual caste. Comparison of the foraging rhythm of this colony with another of the same specie where foraging was performed only by worker caste, showed that working time hours were very similar. After observations on the foraging behavior, both colonies were excavated in order to characterize them (nest size, population composition and estimating of the symbiotic fungus volume). Besides the foraging activity performed only by sexual females, other important observations were highlighted in that colony: low number of workers,... |

| The social wasps are predators of several species of insects and the study of their preys can reveal their potential for programs of biological pest control. During the period of September 2000 to January 2002, were accomplished 70h of collections of the preys captured in twelve nests of Polybia platycephala Richards, placed in urban areas of Juiz de Fora municipality, Minas Gerais State, Brazil. The preys captured by P. platycephala include five orders of insects: Diptera (33.4%), Lepidoptera (28.6%), Hemiptera (12.0%), Hymenoptera (9.4%) e Coleoptera (7.2%). The mean weight of protein charge carried by the wasps was 1.9 ±1.6mg (n = 34, 0.3 - 6.2 mg), and the mean of protein transported per day was 22.8 mg. According to the results, we could estimate that... |
