“…Insects, particularly dung beetles of the subfamily Scarabaeinae (Coleoptera, Scarabaeidae), play an important ecological role in several biological processes occurring in terrestrial environments (NICHOLS et al 2008), such as the control of some vertebrate parasites (BORNEMISSZA 1970, KLEIN 1989, FLECHTMANN et al 1995, soil bioperturbation and pollination (KÜCHMEISTER et al 1998, SAKAI & INOUE 1999, seed dispersal (FEER 1999, ANDRESEN 2002, and nutrient cycling (GUERRA et al 2007).…”

ABSTRACT. The study was conducted at the Mata dos Godoy State Park in Londrina, state of Paraná, Brazil. Baited pitfall traps were installed in the forest, in adjacent abandoned pasture land, and on the borders between these two environments. Every two weeks, from June 1999 to May 2000, the traps were placed for 24 hours and the material was collected every 12 hours. The 4687 specimens of Scarabaeinae collected belong to 13 genera and 27 species. The most frequent were different. Sulcophanaeus menelas, Canthidium aff. trinodosum, O. hirculus, and E. parallelus were the most abundant species, being predominantly diurnal; the first three species were more active on abandoned pasture. Most of the Dichothomius assifer (Eschscholtz, 1822) and D. mormon specimens were captured at night. The latter species was the most abundant in edges, whereas D. assifer, Scybalochantum aff. zischkai, and O. catharinensis can be considered bioindicators because they were either exclusively or highly predominant in the best preserved areas. A larger number of individuals was observed from December 1999 through March 2000, which is the time of the year when adults of Scarabaeinae normally emerge and fly, in the studied region. The highest diversity (88.89%) was observed in February.

“…This amount is sufficient to produce 20 l of extract. Furthermore, the use of NR from colonies of other Atta species is also possible, as the colonies can be artificially maintained in plastic containers in a laboratory, allowing for the production of the NR (Guerra et al, 2007).…”

Nest refuse extract deters ant herbivory

Leaf-cutting ants (LCA) try to reduce the risk of contamination in their colonies by avoiding contact with their nest refuse (NR), as it can harbor substances harmful to them and their symbiotic fungi. Here, we tested whether an aqueous extract with 10% (vol/vol) of NR of the leaf-cutting ant Atta opaciceps Borgmeier (Hymenoptera: Formicidae, Attini) causes a deterrent effect. We placed leaves of Hibiscus rosa-sinensis L. (Malvaceae) sprayed with NR extract or distilled water (control) in the foraging areas of 12 colonies -eight colonies of A. opaciceps and four of Atta sexdens (L.) -for 60 min, on three consecutive days. The fresh weight of remaining leaf fragments between treatments was compared using linear-mixed effect models. Leaf consumption was significantly lower in the presence of NR extract for 48 h, indicating that the NR odor impregnated in the leaves may have been the responsible factor for the deterrence. Further studies are needed to establish a deterrent extract with a broad spectrum and lasting effect on plants, and to better understand the mechanisms involved in deterrence.
