Foraging Area Marking in Two Related Tetramorium Ant Species (Hymenoptera: Formicidae)

The related ants Tetramorium caespitum and T. impurum mark their foraging area in a species-specific, home range and short-lasting manner. Indeed, ants reaching a new area have a slow linear speed which increases during the marking. Conspecific ants are arrested and attracted by marked areas, while heterospecific ants are reluctant to visit them. However, when the latter do visit marked areas, they move more quickly and less sinuously than conspecific ants and do not stay on the areas. The marking is performed in about 3 min by T. caespitum and in 3 to 6 min by T. impurum. If not reinforced, the marking vanishes in the same time intervals. Neither poison gland nor last sternite extracts reproduce the activity of naturally marked areas, whereas a Dufour gland extract does exactly that. Foraging ants touch the ground with the tip of their gaster. Consequently, we can postulate that the workers mark their foraging area with the contents of this gland, which is associated with the sting apparatus, and that they deposit with the extremity of the gaster. Alien conspecific ants are seldom aggressive to one another, even on marked areas. When encountering each other on unmarked areas, heterospecific ants present some aggressive reactions. On marked areas, their aggressiveness is enhanced and intruder ants are restless, while resident ones walk freely. On ground marked by T. impurum, ants of this species are more aggressive than antagonistic T. caespitum workers. The marking of foraging areas thus induces defense against heterospecifics but not against conspecific ants.

Predatory Behavior in Dominant Arboreal Ant Species: The Case of Crematogaster sp. (Hymenoptera: Formicidae)

Crematogaster sp. is a dominant arboreal ant species that captures and retrieves very large prey. Hunting workers forage collectively thanks to short-range recruitment. They detect prey by contact, then rapidly attack, seizing small prey by the body and large prey by a leg. In this study, almost all the active prey were spread-eagled by several workers, even when small enough to permit a single worker to easily master them. While certain workers spread-eagled the prey, others deposited venom on the prey body using their spatulated sting (topical action of the venom). The well-developed arolia on the pretarsus of workers' legs have crucial importance for the success of prey capture (spread-eagling) and transport in an arboreal habitat. These results are compared with those known for other arboreal-dwelling generalist predator ant species.     

Marking of Nest Entrances and Vicinity in Two Related Tetramorium Ant Species (Hymenoptera: Formicidae)

Workers of the related ants Tetramorium impurum and T. caespitum mark the vicinity of their nest entrances in a species-specific manner, as seen by similarities between the behavior of nestmates and that of alien conspecifics (e.g., concerning aggregation, locomotion, orientation, tendency to move, and agonistic behavior). Additionally, they mark the inside of their nest entrances in a colony-specific manner, as seen by the following differences in behavior. Nestmates aggregate on these areas, walk rather slowly, but freely and essentially in the middle of the areas, come toward and very near such areas, are not inclined to escape, and are ready to attack possible intruders. Alien conspecifics do not aggregate, walk quickly, and are reluctant to stay on the areas, come neither toward nor very near the areas, are inclined to escape, and often open their mandibles, mainly when in front of a resident. The marking of the nest entrances is performed by T. impurum in 30 min and by T. caespitum in 15 min. If not reinforced, the marking by both species vanishes in 60 and 50 min, respectively. Extracts of hindlegs, metathorax, or metapleural glands produce in unmarked areas the ethological effect of marked entrances. It may be hypothesized that the marking factor is produced by the workers' metapleural glands and deposited onto the ground, via the hindlegs of ants leaving the nest. A worker's head has a species- but not a colony-specific ethological effect. An isolated alien conspecific's head is never attacked, whereas a thorax with abdomen is. This explains why, by opening its mandibles (and then presumably emitting a mandibular gland pheromone), a conspecific ant momentarily inhibits the attack of a nonnestmate. According to Hölldobler and Wilson (1990), the marking of the inside of T. impurum and T. caespitum nest entrances is a territorial and nest-entrance marking, whereas the marking of the close vicinity of the entrances is a home-range marking, as is the marking of the foraging area. These markings are in accordance with the fact that T. impurum foragers deposit their trail pheromone as far as the opening of the nest entrance.

Recruitment Behavior in the Ant Genus Polyrhachis (Hymenoptera, Formicidae)

We present a detailed behavioral analysis of the signals involved in recruitment of 11 syntopic Polyrhachis species from West Malaysia. We found a considerable variety of recruitment techniques, including social carrying behavior, tandem running, group recruitment, and a technique which we call leader-independent trail communication. The latter mode superficially resembles chemical mass communication (sensu Wilson, 1962). All these recruitment techniques involve mechanical invitation behavior inside the nest, comprising back-and-forth jerking or pulling movement often combined with a sideways waggling. However, not in all cases of leader-independent trail communication is a mechanical invitation behavior obligatory. The trail pheromone of all investigated Polyrhachis species originates from the hindgut. Only in the tandem running P. proxima do additional secretions from the poison gland appear to be involved in tandem calling.     

Catalogue of the ants (Hymenoptera, Formicidae) of Bulgaria

The present catalogue of the ants (Hymenoptera, Formicidae) of Bulgaria is made on a base of critical reconsideration of literature (covering the period from 1892 till 2009 and part of 2010) as well as on examination of the authors' and several museum's collections. A lot of data were omitted in the previous Bulgarian monograph on ants, lots of new data were recently added and many important additions and alterations were made due to taxonomic revisions of Eurasian Formicidae during the last three decades. Two new species are reported for the country [Temnothorax graecus (Forel, 1911) and Temnothorax cf. korbi (Emery, 1924)].This catalogue contains a list of 163 ant species belonging to 40 genera of 6 subfamilies now known from Bulgaria. Synonyms and information on the previously reported names in relevant publications are given. Known localities of the species are grouped by geographic regions. Maps with concrete localities or regions for each species were prepared. The conservation status of 13 ant species is given as they are included in IUCN Red List of Threatened Species and Bulgarian Biodiversity Act. In comparison with adjacent Balkan regions the ant fauna of Bulgaria is quite rich and its core is composed of South European elements.
