When the mermithid parasite of mosquitoes, Reesimermis nielseni Tsai & Grundmann, was mass reared in the laboratory, the lower densities of hosts ( Culex Pipiens quinquefasciatus Say) produced a higher percentage of parasitism and greater theoretical yield of female nematodes. However, the reduced efficiency at higher host densities was more than offset by the economy of production at the higher densities. High parasitism (in excess of about 85%) reduced the ultimate production of preparasitic… Expand
Numerical relationships between a nematode parasite Romanomermis culicivorax and its host population, Culex pipiens molestus larvae.
The present paper deals essentially with the results of experimental infection and the hostfinding behaviour of the nematode population, and the effect of the host densities and the ratio of parasite to host on the percentage parasitism. Expand
Effects of Host Diet on Romanomermis culicivorax, a Mermithid Parasite of Mosquitoes.
When larval mosquitoes (Aedes aegypti) infected with the mermithid nematode Romanomermis culicivorax were fed on a diet low in quantity or protein content or both, the number of postparasites whichExpand
Optimizing laboratory production of Strelkovimermis spiculatus (Nematoda: Mermithidae) with a discussion of potential release strategies for mosquito biological control
Postparasite-inoculation methods were compared under culture conditions reflecting two categories of mosquito habitat (permanently flooded or desiccated cultures) and the J2s infected mosquito larvae under both conditions. Expand
Role of mermithid nematodes in biological control of mosquitoes.
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
A new potential host and transmission routes of Thripinema nicklewoodi, an entomogenous nematode of western flower thrips
Results indicate that T. tabaci is a new potential host of T. nicklewoodi, and that nematodes penetrated larval F. occidentalis through the intersegmental membranes of a coxal cavity or the abdomen and exited adult thrips via the anus. Expand
Status of Research on Biological Agents for the Control of Mosquitoes
Large areas of irrigated farmland and vast marshes along sea coasts frequently produce very high mosquito populations thus retarding livestock production and further agricultural development, and the annoyance factor brought about by high density mosquito populations cannot be overstated. Expand
The Use of Biodegradable Pesticides in Public Health Entomology
In his presidential address to the American Society of Tropical Medicine and Hygiene, W. C. Reeves (1972) asked: “Can the war to contain infectious diseases be lost?” That remains a good questionExpand
Roles of resource and partner availability in sex determination in a parasitic copepod
An experimental analysis on the combined action, during larval development, of availability of food resources and sexual partners in the sex determination of this species is reported. Expand
