Abstract. 1. One of the first activities of minim workers in incipient fire ant nests is mutual brood raiding, the amalgamation of nests through the reciprocal stealing of brood and defection of workers. 

Effects of foundress number on brood raids and queen survival in the fire ant Solenopsis invicta

Results show that the competitive advantages of multiple-queen colonies are sufficient to counterbalance the increased mortality of queens within groups only when the number of foundresses is greater than two and when colonies are founded at high density.

Spatial dynamics of colony interactions in young populations of the fire ant Solenopsis invicta

The results show that it may be difficult to infer the degree of past or current competition by passive analysis of spatial data even when field experiments show that the probability of mortality depends on local spacing.

Newly founded colonies of the fire ant Solenopsis invicta compete intensely by brood raids, which result in a rapid reduction of colony density. Experimental plantings of colonies and analyses of

Overall, this study suggests that newly mated queens are under strong selection to leave the soil surface and do so by using any available holes, whether dug by another queen or of some other origin; they are attracted to other queens, and are more likely to cofound as contact with the potential cofoundress becomes more frequent.

Reproductive conflicts in cooperative associations of fire ant queens (Solenopsis invicta)

Two factors, the queens' relative fighting ability and their relative contribution to worker production (assuming that workers can recognize and selectively favour their mother) have been proposed to influence the survival prospects of individual queens within associations and the effect was tested in the fire ant Solenopsis invicta.

SummaryThe colony founding characteristics of newly mated fire ant queens from monogyne colonies were studied in the field and in the laboratory under haplo- and pleometrotic conditions. Initial

Costs and benefits of joint colony founding in Australian Acacia thrips

This study provides the first analysis of costs and benefits associated with pleometrosis for Australian Dunatothrips, which form domiciles by glueing together phyllodes (leaves) of their Acacia host plant, and identified two benefits.

Impact of imidacloprid on new queens of imported fire ants, Solenopsis invicta (Hymenoptera: Formicidae)

Neonicotinoid insecticides are commonly used in managing pest insects, including the imported fire ant, Solenopsis invicta Buren. There is increasing evidence that neonicotinoid insecticides at

Cooperation among unrelated individuals: the ant foundress case.

Unequal partitioning of reproduction and investment between cooperating queens in the fire ant, Solenopsis invicta, as revealed by microsatellites

The finding that the queen most likely to win the fights is the one with above–average maternity, which may explain why workers apparently do not attempt to influence the outcome of fights.



Brood Raiding in the Fire Ant, Solenopsis invicta (Hymenoptera: Formicidae): Laboratory and Field Observations

Rec reciprocal brood raiding took place along odor trails connecting various numbers of nests from a few centimeters to 20 m apart, and its effect was to aggregate the brood and workers from local populations of incipient colonies into a few locations.

Colony Founding by Queens of the Red Imported Fire Ant, Solenopsis invicta

The method by which newly mated queens of the red imported fire ant, Solenopsis invicta Buren, found new colonies was investigated and optimum temperature was found to be between 27.5 and 32°C.

Production and Flight of Alate Red Imported Fire Ants

Emergence of alate Solenopsis invicta Buren from several habitats in northern Florida averaged 187,000/acre/year, and first flights composed of alates which developed from the new season's brood occurred in late April and early May.

Biology and control of imported fire ants.

The purpose here is to review this research, although because of space limitations, much of the recent work concerning the chemical toxicology and persistence of mirex, the chemical currently used for control of imported fire ants.

Intraspecific Brood Raiding, Territoriality, and Slavery in Ants

Recent research on the establishment of colonies in several non-dulotic, intra-specifically territorial ants provides support for and an extension of the territorial hypothesis as a general explanation for dulosis.

Pupation in mycetophilid flies: a correction

In a previous paper (Eberhard 1970) I made several claims regarding two species of the mycetophilid fly genus Leptomorphus: 1) the larval cuticle is not shed prior to pupation; 2) the last two and
