Mating behavior in the ant, Myrmecina graminicola (Myrmicinae)
Insectes Sociaux, 2003Sexual behavior of Myrmecina graminicola in laboratory conditions is described. Virgin females, both gynomorphs and intermorphs, exhibit an inconspicuous "sexual calling", apparently depositing a sex pheromone on the substrate close by. The sexual pheromone is produced in the poison gland.

Direct homing behaviour in the antTetramorium caespitum(Formicidae, Myrmicinae)
Animal Behaviour, 1998Direct homing refers to the behaviour whereby an ant with food runs in an almost straight line to the nest. We determined whether non-polarized light acts as a directional cue in the direct homing behaviour of the grass ant, Tetramorium caespitum. We carried out tests (1) under a blue sky or in total overcast conditions in the field, and (2) with a ...

A hitherto unknown ethological factor in the ant Tetramorium impurum (Myrmicinae)
Behavioural Processes, 1991In Tetramorium impurum, an ethological factor can be found on workers' last visible abdominal sternite. For a short time, it attracts ants, increases their linear speed and enhances the efficiency of the trail pheromone. This factor is not colony-specific but may play a role in the foraging and recruiting systems of the species.

Social organization and reproduction inOcymyrmex foreli (Formicidae: Myrmicinae)
Insectes Sociaux, 1989Colonies ofOcymyrmex foreli contained 16–1586 adults of which 4–20% were ergatoid queens the remainder being sterile workers. Each colony contained one inseminated ergatoid queen only and colonies were monogynous. Workers and virgin queens were similar in size and appearance but had distinctive ovaries; queens had significantly more ovarioles than ...

Two new species of the ant genus Myrmecina (Hymenoptera: Formicidae: Myrmicinae) from Sumatra
Zoosystematica Rossica, 2019Two new species of the ant genus Myrmecina Curtis, 1829 are described and illustrated based on the worker and queen castes collected in Sumatra, Indonesia under the names M. andalas sp. nov. and M. nitidiuscula sp. nov.

Orientation of mounds in the antSolenopsis invicta (Hymenoptera, Formicidae, Myrmicinae)
Insectes Sociaux, 1977Most mounds of the myrmicine antSolenopsis invicta in the area of Tallahassee (Florida, U.S.A.), were found to be oval in shape with the long axis of the mound oriented in a north-south direction. This «magnetic» orientation is of probable thermoregulatory significance and is comparable to mound orientation phenomena found in the ant subfamily ...

Identification of trail pheromone of the antTetramorium caespitum L. (Hymenoptera: Myrmicinae)
Journal of Chemical Ecology, 1984The trail pheromone of the antTetramorium caespitum L. is a 70∶30 mixture of 2,5-dimethylpyrazine and 3-ethyl-2, 5-dimethylpyrazine. The average total amount of the two pyrazines present in the poison vesicle was found to be 3.9 ng per ant, of which 2.7 ± 0.4 ng is 2,5-dimethylpyrazine and 1.15 ±0.25 ng is 3-ethyl-2,5-dimethylpyrazine.
