Plants of the genus Aristolochia have been frequently reported as important medicinal plants. Despite their high bioactive potential, to date, there are no reports of their effects on leaf-cutting ants. Therefore, the present study aimed to evaluate the insecticidal activity of the essential oil of Aristolochia trilobata and its major components on Atta sexdens and Acromyrmex balzani, two speci...

Insects, in general, are agile creatures capable of navigating uneven and difficult terrain with ease. The leaf-cutter ants (Atta), specifically, are agile, social insects capable of navigating uneven and difficult terrain, manipulating objects in their environment, broadcasting messages to other leaf-cutter ants, performing collective tasks, and operating in cooperative manners with others of ...

Ants (Hymenoptera: Formicidae) are social insects and important pests in the urban environment. The main groups of pest ants environment leafcutter house ants. Leaf-cutter cause crescent-shaped defoliation plants, where it causes problems gardens ornamental plants. Domestic human health problems, contaminate food equipment buildings. In this work, we propose an integrated ant management program...

The physical concept of quantum entanglement state was applied to cooperative behavior of two ants (agents) pushing a pebble, which is too heavy for one ant, developed by Summhammer. His conventional study showed that the two quantum-inspired ants imitating quantum entanglement state can push the pebble up to twice relative to the two classical ants in independent relation. In order to set up a...

one of the most important extensions of the capacitated vehicle routing problem (cvrp) is the vehicle routing problem with simultaneous pickup and delivery (vrpspd) where customers require simultaneous delivery and pick-up service. in this paper, we propose an effective ant colony optimization (eaco) which includes insert, swap and 2-opt moves for solving vrpspd that is different with common an...

The Argentine ant, Linepithema humile, was found established in New Zealand in 1990. During summer 2001/2002 the spread of Argentine ants from urban environments into native habitats was investigated. During an initial large-scale survey around the northern cities of Auckland and Whangarei, Argentine ants were observed at 35 of 211 sites. Eight sites in Auckland were subsequently surveyed in gr...

Homing ants have been shown to associate directional information with familiar landmarks. The sight of these local cues might either directly guide the path of the ant or it might activate a landmark-based vector that points towards the goal position. In either case, the ants define their courses within allocentric systems of reference. Here, we show that desert ants, Cataglyphis fortis, forced...

Abstract A detailed study of the holotype of Sphecomyrma canadensis Wilson 1985 from Canadian amber led to the conclusion that the specimen belongs to a genus here named Boltonimecia gen.nov. not previously described. The taxonomy of stem ants ...

We caught solitary foragers of the Australian Jack Jumper ant, Myrmecia croslandi, and released them in three compass directions at distances of 10 and 15 m from the nest at locations they have never been before. We recorded the head orientation and the movements of ants within a radius of 20 cm from the release point and, in some cases, tracked their subsequent paths with a differential GPS. W...

Ant-fungus associations are well known from attine ants, whose nutrition is based on a symbiosis with basidiomycete fungi. Otherwise, only a few non-nutritional ant-fungus associations have been recorded to date. Here we focus on one of these associations involving Allomerus plant-ants that build galleried structures on their myrmecophytic hosts in order to ambush prey. We show that this associ...
