Antibacterial properties of contact defensive secretions in neotropical Crematogaster ants J. Venom. Anim. Toxins incl. Trop. Dis.
Quinet,Y; Vieira,RHSF; Sousa,MR; Evangelista-Barreto,NS; Carvalho,FCT; Guedes,MIF; Alves,CR; de Biseau,JC; Heredia,A.
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 venom of three neotropical Crematogaster ant species (C. distans, C. pygmaea and C. rochai) against gram-negative (Escherichia coli and Pseudomonas aeruginosa) and gram-positive (Enterococcus faecalis and Staphylococcus aureus) bacteria. Sterile filter paper was soaked with C. distans, C. pygmaea or C. rochai crude venom and placed on an agar dish that was inoculated with bacterial suspensions. The agar dish was incubated overnight at 37ºC and examined for zones of growth inhibition. For each tested venom and...

Ants monopolise plant resources by shelter-construction Acta Amazonica
ESKILDSEN,Louise I.; LINDBERG,Annika Büchert; OLESEN,Jens M..
In Ecuadorean Amazonas, Crematogaster ants (Myrmicinae) were observed to construct shelters of debris and plant trichomes covering and hiding extrafloral nectaries of Passiflora auriculata vines. This is seen as an advanced way of excluding competing ants from a food source.
