ABSTRACT This study was designed to understand the effects of the interspecific competition between red imported fire ant, Solenopsis invicta Buren and two native ant species, Pheidole fervens Smith and Monomorium chinense Santschi, by conducting colony interference and individual confrontation tests under laboratory conditions. The colony interference test showed that both native ant species, owing to their numerical advantage, killed the Solenopsis invicta virus-1 (SINV-1)-infected or healthy… 

Manipulation of Viral Titers of Solenopsis invicta Virus-1 by RNA Interference in Laboratory Colonies of Red Imported Fire Ant1

Increases and decreases of viral titers of SINV-1 directly correlated with the increases and decreases in mortality and RNA interference (RNAi) is a known regulator of RNA viruses in biological systems and is an emerging biologically based insect control method.

Introduced Pheidole of the world: taxonomy, biology and distribution

A detailed taxonomic resource for identifying and studying ants in the genus Pheidole that have established beyond their native ranges is provided, to facilitate identification of pest species, determination of climatic and habitat requirements, discovery of pest origins, horizon scanning and assessment of invasion pathways.

Viruses and their effects in ants (Hymenoptera: Formicidae)

It is suggested that horizontal transmission is a common mode of infection in ants as they share food via trophallaxis, although vertical transmission of viruses in eggs from queens has been observed, and approaches for viral discovery in invasive ants that focus on colony monitoring in their native range are recommended.

The ants (Hymenoptera: Formicidae) and their parasites: effects of parasitic manipulations and host responses on ant behavioral ecology

This work highlights the parallels that can be found across parasite-ant symbioses that result in manipulated behaviors, such as summiting, phototaxis, substrate biting, and wandering, and points out the many present knowledge gaps that could be filled by efforts ranging from novel parasite discovery, to more detailed behavioral observations and next-generation sequencing to start uncovering mechanisms.

Viral infections in fire ants lead to reduced foraging activity and dietary changes

Findings provide the first evidence for virus-induced behavioral responses and dietary shifts in shaping the host-pathogen interactions in fire ants and suggest a possible mechanism for how fire ant colonies respond to viral epidemics.

Pathogens, parasites, and parasitoids of ants: a synthesis of parasite biodiversity and epidemiological traits

This work provides a foundation for future work that will begin to untangle the ecological drivers of ant-parasite relationships and the evolutionary implications thereof, and synthesizes major patterns in parasite ecology by categorizing how parasites encounter their ant hosts, whether they require host death as a developmental necessity, and how they transmit to future hosts.

Progress of biological invasions research in China over the last decade.

Several issues that need to be addressed in invasive species research in the future are suggested, including territory-wide inventories, evolutionary ecology and genomics, direct and indirect ecosystem-level consequences, interactions between major components of global change and biological invasions, and management and control technologies.

Volatile Terpenes and Terpenoids from Workers and Queens of Monomorium chinense (Hymenoptera: Formicidae)

Twenty-one volatile terpenes and terpenoids were found in Monomorium chinense Santschi, a native Chinese ant, by using headspace solid-phase microextraction coupled with gas-phase chromatography and mass spectrometry, which makes this ant one of the most prolific terpene producers in insect.

Different bacterial and viral pathogens trigger distinct immune responses in a globally invasive ant

Invasive species populations periodically collapse from high to low abundance, sometimes even to extinction. Pathogens and the burden they place on invader immune systems have been hypothesised as a

Geographical variation in Japanese cedar shapes soil nutrient dynamics and invertebrate community

The effects of the provenance of a canopy tree species shape the soil invertebrate abundances and composition by altering the concentration of nutrients in the soil.



Invasive interactions of Monomorium minimum (Hymenoptera:Formicidae) and solenopsis invicta (Hymenoptera:Formicidae) infected with thelohania solenopsae (Microsporida:Thelohaniidae) in the laboratory

S. solenopsae were not able to defend their colony or prevent competing ants from invading as well as uninfected S. invicta colonies, and M. minimum was the more invasive species when compared to S. Invicta.

Aggressive Interactions Between Solenopsis invicta and Linepithema humile (Hymenoptera: Formicidae) Under Laboratory Conditions

Fire ant baits may have long-term effects on intercolonial aggression between S. invicta and L. humile, especially when Argentine ant populations are high in the summer.

Mechanisms of interspecific competition among an invasive and two native fire ants

The mechanisms of interspecific competition among an invasive and two native Solenopsis fire ant forms were investigated in a series of laboratory experiments. In separate trials each with a

Predation on Founding Queens of Solenopsis Invicta by Workers of Conomyrma Insana

Solenopsis invicta Buren founding queens are especially vulnerable to predation during and following the nuptial flight. Conomyrma insana (Buckley) workers are effective predators of the queens in

Simplified approaches to determine the attractant preference of Solenopsis invicta (Hymenoptera : Formicidae)

The results showed that of the four ant densities investigated, the medium ant density most consistently had more workers at the food lures than the other ant density situations, and that significantly fewer foragers were observed in the foraging areas when a queen was present, then when the queen was absent.

Loss of microbial (pathogen) infections associated with recent invasions of the red imported fire ant Solenopsis invicta

The results support the general prediction that invasive species lose many of their natural enemies during invasion and the conspicuous absence of some of these microbes in recently established populations may result from strong selection against founders due to fitness costs associated with harboring detrimental infections.

A new fire ant (Hymenoptera: Formicidae) bait base carrier for moist conditions.

T-bait is an efficient fire ant bait, especially under moist conditions, based on its properties of remaining attractive to the fire ants when wetted, combined with its ant-killing abilities both in the laboratory and in the field.

Predators of Solenopsis invicta Queens Prior to Successful Colony Establishment

An investigation was made in north Florida of the biotic factors affecting female Solenopsis invicta Buren from the beginning of the nuptial flight until the emergence of minum workers in newly established colonies, finding that S. Invicta workers are again important.

Importance of large colony size for successful invasion by Argentine ants (Hymenoptera: Formicidae): Evidence for biotic resistance by native ants

The results suggest that Iridomyrmex may reduce the spread of Argentine ants, and that Argentine ants may need to attain large colony sizes in order to survive in the presence of Iridomermex.
