Although the so called "green islands" of the semi-arid Brazilian "Nordeste" are economically, socially, and ecologically important, relatively little is known about their biodiversity. We present the results of the first survey of the ground-dwellin

Crematogaster ants use their contact venoms to compete with other ants. Although those venoms are used primarily as repellent and toxic secretions, they may have other functions. The present study aimed to test the antibacterial property of abdominal

Bioassays were performed to investigate and compare the toxic properties of the contact venoms of three Neotropical Crematogaster species (C. sp. prox. abstinens, C. distans and C. brevispinosa rochai), whose main venom compounds are chemically diffe

Defensive behaviour and biological activities of the abdominal secretion in the ant Crematogaster scutellaris (Hymenoptera: Myrmicinae)

Publikováno v: Behavioural Processes. 67:427-440

Using bioassays, the defensive behaviour of Crematogaster scutellaris and the biological activities of its abdominal secretion were investigated. Beside classical aggressive behaviours such as grips, C. scutellaris workers performed frequent characte

Fourteen new long-chain derivatives (1j-11, 2j-21, 4a-4f, 6, and 7) have been isolated, together with the known 4-oxo-2,5-dienyl acetates 1g-1i and 4-oxo-2,5-dienals 2g-2i, from the defensive secretions of three species of Crematogaster ants from Pap
