Messor ants

Heredia A. and Detrain C. (2000) Worker size polymorphism and ethological role of sting associated glands in the harvester ant Messor barbarus. Insectes Soc. 47, 383-389. 

Analysis of hydrocarbons from anal fluids (feces) involved in nest marking by the ant Messor capitatus (Grasso et al., 2005) suggests that territory marking using abdominal secretions issued from the rectal sac may be another labeling function by the way of abdominal secretions. The same authors reported that the hydrocarbons in the feces were similar to those hydrocarbons on the cuticle of workers. 

New sources of anabasine (11) continue to be reported. Anabasine was isolated from Saurauia excelsa, representing the first report of 11 in this genus [75]. Out of nineteen hoplonemertine species surveyed, 11 was found only in Zygonemertes virescens and Amphiporus lactifloreus [76]. It was found to be the major component in the poison gland of the ants Messor ebeninus [77] and M. bouvieri [78], and a minor component in M. capensis [79].
