There has been a renewed interest in the parasites of mosquitoes as the search for organisms that could prove valuabl e in biological control is pursued. As a resul t of such a study in northern Utah and souther n Wyoming regions, a species of mermithid nematode was found inhabiting six mosquit o species at a site near Lone Tree, Uinta County, Wyoming. Following an extensive study of the lif e history, pathogenesi in mosquitoes , and morphology of this organism, a new genus and species name is… Expand
A review of the mermithid parasites (Nematoda:Mermithidae) described from North American mosquitoes (Diptera:Culicidae) with descriptions of three new species.
TLDR
Three new species of Romanomermis are described and a brief commentary is included on the taxonomic utility of length and degree of fusion of the spicules, body shape, cuticular fibres, and double molt to adult. Expand
A Contribution to our Knowledge of the Mermithidae (Nematoda).
The genera of the insect parasitic nematode family Mermithidae axe reviewed, and 16 of them axe redescribed and illustrated. Information is given on methods of rearing adult mermithid specimens andExpand
Role of mermithid nematodes in biological control of mosquitoes.
TLDR
High levels of parasitism can be obtained in natural populations of mosquitoes at reasonable dosages and preparasitic nematodes can be applied easily by using many of the standard techniques used to apply insecticides. Expand
Comparative biology of the Wyoming and Louisiana populations of Reesimermis nielseni, parasitic nematode of mosquitoes.
TLDR
SEM photos of buds and tubes on mature spores confirm the observations of Allen (1), and a Denton DV-502 high vacuum evaporator operat ing at 3 x 10 -5 T o r r was used to spread a standard layer of gold on specimens. Expand
Development and fecundity of Reesimermis nielseni, a nematode parasite of mosquitoes.
TLDR
Maturation of the mermithid nematode Reesimermis nielseni to the adult stage began by the tenth day after emergence of the nematodes from their hosts at ambient temperatures (24-27 C) and some oviposition was still taking place 150 days later. Expand
Effects of temperature and photoperiod on the infection of two mosquito species by the mermithid Romanomermis culicivorax.
TLDR
Larval mortality during the 48-h exposure period was due primarily to nematode infection, and Photoperiod had no effect on infection. Expand
Current status of nematodes for the biological control of insects
TLDR
This review highlights published research on the principal entomogenous nematodes that have potential as biological control agents of insects and suggests that they will remain ‘on the shelf’ until the need for such biological control provides small businesses with the incentive to make them available for general use.

Adaptive Variation in Environmental Sex Determination in a Nematode
TLDR
Here is the first evidence of adaptive variation in the expression of ESD in a spatially patchy environment, as predicted by adaptive-sex-ratio theory. Expand
The effects of temperature on the infectivity of Romanomermis culicivorax.
The survival time (ST) of the preparasitic larvae of Rornanomermis culicivorax was determined by measuring motility at 1, 6, 12, 18, 21, 27, 30, and 37 C; the ST at each of these temperatures wasExpand
Effect of Storage at Low Temperatures on Development and Survival of Postparasitic Juveniles of Romanomermis culicivorax (Nematoda: Mermithidae).
Development of postparasites and adult females of Romanomermis culicivorax Ross and Smith, 1976 may be retarded by keeping cultures at 10 or 15 C for 15 wk. Storage at 5 C resulted in high mortalityExpand
