Myrmecophilous pygmephoroid mites (Acari: Pygmephoroidea) associated with Lasius flavus (Hymenoptera: Formicidae) in Russia.
Twenty four species of pygmephoroid mites (Acari: Pygmephoroidea: Neopygmephoridae, Scutacaridae, Microdispidae) are recorded from the ant Lasius flavus (Fabricius) or from its nests from Western Siberia and Crimea. Four of them of the genus Scutacarus Gros, 1845 (Acari: Scutacaridae), S. insolitus sp. nov., S. heterotrichus sp. nov., S. moseri sp. nov. and S. sibiriensis sp. nov. are described...
متن کاملTemporal organization of bi-directional traffic in the ant Lasius niger (L.).
Foraging in ants is generally organized along well-defined trails supporting a bi-directional flow of outbound and nestbound individuals and one can hypothesize that this flow is maximized to ensure a high rate of food return to the nest. In this paper we examine the effect of bottlenecks on the temporal organization of ant flow. In our experiments ants had to cross a bridge to go from their ne...
متن کاملTriggering and persistence of trail-laying in foragers of the ant Lasius niger.
In the ant Lasius niger, the ability to ingest their own desired volume is the key criterion that rules the recruiting behaviour of scouts. This volume acts as a threshold triggering the trail-laying response of foragers. In this paper, we show that this desired volume is specific to each individual and is kept constant over successive trips to a food source. This individual specificity contras...
متن کاملTrails and U-turns in the Selection of a Path by the Ant Lasius niger
A series of laboratory experiments show how colonies of the ant lxlsius niger systematically select the shorter of two paths of varying length and form between nest and foraging area, and do so with a large majority of foragers. Three different mechanisms were considered to contribute to this selection, and were evaluated by comparing mathematical models with experimental data. Bi-directional t...
متن کاملEffect of pleometrosis and brood transplantation on colony growth of the black garden ant, Lasius niger
In response to intraand interspecific competition, ant colonies have evolved mechanisms to maximize early colony growth. Through the analysis of photographic images, this study describes the individual effect of two different strategies, pleometrosis and pupae transplantation, on the growth of Lasius niger colonies. Results showed that both methods had an overall positive effect on colony produ...
