MORTALITY OF ANT (HYMENOPTERA: FORMICIDAE) PEST SPECIES EXPOSED TO SODIUM HYDROGEN CARBONATE

Australian species of the ant genus Dolichoderus (Hymenoptera: Formicidae).

The Australian species of the ant genus Dolichoderus are revised. The fauna contains 27 species belonging to four species goups, the australis group (5 species, 2 newly described), the doriae group (6 species, 2 newly described), the scabridus poup (6 species, 1 newly described) and the scrobiculatus group (10 species, 4 newly described). The former subspecies niger Crawley and rufotibialis Cla...

Dominant Ant Species in Four Habitats in Hawaii (Hymenoptera: Formicidae)

The Hawaiian Islands represent one of the few ecosystems in the world that lacks native ants and thus represents a unique environment in which to study invasion biology. In the course of a study of behavioral interactions among invasive ant species, we collected the most abundant ants from four different field sites on the islands of Oahu and Hawaii. One year after the original collections, we ...

A North Florida Ant Fauna (Hymenoptera: Formicidae)

Invasive ant Tapinoma melanocephalum (Hymenoptera: Formicidae): A rare guest or increasingly common indoor pest in Europe?

The ghost ant (GA), Tapinoma melanocephalum (Fabricius, 1793), is one of the most common invasive species of ants (Hymenoptera: Formicidae) in the world. While in its native tropical region it is both an ordinary indoor and outdoor pest, it occurs only indoors in the temperate zone, where increasingly more records of this species have been published since 1887. In this study, the current distri...

Effect of particulate contamination on adhesive ability and repellence in two species of ant (Hymenoptera; Formicidae).

Tarsal adhesive pads are crucial for the ability of insects to traverse their natural environment. Previous studies have demonstrated that for both hairy and smooth adhesive pads, significant reduction in adhesion can occur because of contamination of these pads by wax crystals present on plant surfaces or synthetic microspheres. In this paper, we focus on the smooth adhesive pads of ants and s...
