Polygyny and Polydomy in Three North American Species of the Ant Genus Leptothorax Mayr (Hymenoptera: Formicidae)
TLDR
It is argued that some of the same factors which might predispose one species to evolve into a social parasite might make resistance to parasitism difficult for a closely related species. Expand
Population biology of entomopathogenic nematodes: Concepts, issues, and models
TLDR
The structure of entomopathogenic nematode populations, the various biotic and abiotic factors that influence them, and procedures for sampling and modeling their spatial and temporal dynamics are discussed. Expand
Ecology in the service of biological control: the case of entomopathogenic nematodes
TLDR
Increased understanding of the ecology of entomopathogenic nematodes has enabled better matches between parasites and hosts, and more accurate predictions of field performance, which underline the importance of a strong partnership between basic and applied ecology in the area of biological control. Expand
Lethal fighting among dimorphic males of the ant, Cardiocondyla wroughtonii
TLDR
The authors' observations reveal that the ergatoid males are morphologically and behaviorally highly specialized for fighting, and regularly engage in lethal combat with one another so that there is typically only a single ergatoids male per nest. Expand
Entomopathogenic Nematodes in the Soil Environment: Distributions, Interactions and the Influence of Biotic and Abiotic Factors
Entomopathogenic nematodes (EPNs) in the families Steinernematidae and Heterorhabditidae are important agents for the biological control of soil insect pests in natural and managed ecosystems (Denno,Expand
Comparison of beneficial traits among strains of the entomopathogenic nematode, Steinernema carpocapsae, for control of Curculio caryae (Coleoptera: Curculionidae)
TLDR
Overall, Breton, DD136, Italian, and Kapow strains were ranked inferior to other strains and Agriotos, All, and Sal strains were superior when desiccation was a factor. Expand
WATER STRESS AND ROOT INJURY FROM SIMULATED FLOODING AND DIAPREPES ABBREVIATUS ROOT WEEVIL LARVAL FEEDING IN CITRUS
TLDR
It is suggested that limited soil waterlogging and early root weevil larval control would be useful for plant protection in the face of environmental stress from flooding. Expand
Heterorhabditis mexicana n. sp. (Rhabditida: Heterorhabditidae) from Tamaulipas, Mexico, and morphological studies of the bursa of Heterorhabditis spp.
TLDR
The morphological and molecular data indicate that this nematode is a new species and is sufficient to identify cladogenesis and delimit H. mexicana n. Expand
Collective cues as a basis for nestmate recognition in polygynous leptothoracine ants.

  • 1 June 1988
TLDR
A bioassay based on aggression by laboratory colonies toward workers introduced into their nests was used in conjunction with isolation and interspecific-adoption experiments to test thecollective hypothesis and provides strong evidence for the collective hypothesis. Expand
Multiple Queens in Ant Nests: Impact on Genetic Structure and Inclusive Fitness
TLDR
It is concluded that the nest is the functional unit of selection for these populations of Leptothorax longispinosus, and across nests, there appears to be consistent, strong, stabilizing selection for intermediate levels of polygyny in two northern populations. Expand
