Background: The entomopathogenic nematode Heterorhabditis bacteriophora and its symbiotic bacterium, Photorhabdus luminescens, are important biological control agents of insect pests. This...
Laboratory Colonization of Aedes japonicus japonicus (2008)
Eric Williges, Ary Farajollahi, Jamesina J. Scott, Linda J. Mccuiston, Wayne J. Crans, Randy Gaugler
We describe methodology used for the laboratory colonization of Aedes japonicus japonicus, an exotic mosquito species native to eastern Asia and first collected in New Jersey as larvae in 1999. We...

Culex territans Walker (Diptera: Culicidae) larvae share nonpolluted freshwater habitats with amphibians, which are bloodmeal hosts of their adults. To examine synchrony of Cx. territans with...
Phonotaxis to Amphibian Vocalizations in Culex territans (Diptera: Culicidae) (2008)
Kristen Bartlett-Healy, Wayne Crans, Randy Gaugler
Culex territans Walker (Diptera: Culicidae) acquires bloodmeals from amphibian hosts. Females overwinter as inseminated adults and exit diapause in New Jersey when spring peepers (Pseudacris...

We compared Heterorhabditis bacteriophora GPS11 expressed sequence tags (ESTs) to the ESTs of animal-parasitic, human-parasitic, plant-parasitic, and free-living nematodes. We identified 127...

We tested biological control agents for the control of 3rd-instar scarab turfgrass pests, both for the masked chafer Cyclocephala hirta LeConte and the Japanese beetle, Popillia japonica Newman. The...
Bai, Cheng, Shapiro-Ilan, David I., Gaugler, Randy, Yi, Shuxia
Entomopathogenic nematodes are used for biological control of insect pests. A method for improved cryopreservation of infective juvenile stage nematodes has been developed using Steinernema...
Effects of Etomopathiogenic Nematodes on Meloidogyne javanica on Tomatoes and Soybeans
Fallon, Declan J., Kaya, Harry K., Gaugler, Randy, Sipes, Brent S.
Two Hawaiian isolates of Steinernema feltiae MG-14 and Heterohabditis indica MG-13, a French isolate of S. feltiae SN, and a Texan isolate of S. riobrave TX were tested for their efficacy against the...
Mating and Sexual Communication by Steinernema carpocapsae (Nemata: Steinernematidae)
Lewis, Edwin E., Barbarosa, Bruno, Gaugler, Randy
Entomopathogenic nematodes are lethal insect parasites that reproduce exclusively inside their hosts in nature. Infection decisions made by the free-living infective-stage juveniles have an impact on...
Optimization of Inoculation for In Vivo Production of Entomopathogenic Nematodes
Shapiro-Ilan, David I., Gaugler, Randy, Tedders, W. Louis, Brown, Ian, Lewis, Edwin E.
Entomopathogenic nematodes are potent biopesticides that can be mass-produced by in vitro or in vivo methods. For in vivo production, consistently high infection rates are critical to efficiency of...
Compatibility of Soil Amendments with Entomopathogenic Nematodes
Bednarek, Andrzej, Gaugler, Randy
The impact of inorganic and organic fertilizers on the infectivity, reproduction, and population dynamics of entomopathogenic nematodes was investigated. Prolonged (10- to 20-day) laboratory exposure...
Wang, Yi, Gaugler, Randy, Cui, Liwang
The infectivities of Steinernema carpocapsae, S. glaseri, S. scapterisci, and Heterorhabditis bacteriophora to Japanese beetle larvae, Popillia japonica, and house cricket adults, Acheta domesticus,...
Genetic Variability among Strains of the Entomopathogenic Nematode Steinernema feltiae
Gaugler, Randy, McGuire, Terry, Campbell, James
A systematic program of genetic improvement was initiated by assessing the phenotypic variation of Steinernema feltiae strains for two traits assumed to limit efficacy: ultraviolet tolerance and...
Influence of Soil pH and Oxygen on Persistence of Steinernema spp.
Kung, Shang-Ping, Gaugler, Randy, Kaya, Harry K.
Survival of infective juveniles of Steinernema carpocapsae and Steinernema glaseri gradually declined during 16 weeks of observation as the tested soil pH decreased from pH 8 to pH 4. Survival of...
Glazer, Itamar, Gaugler, Randy, Segal, Daniel
Genotypic variation among infective juveniles of Heterorhabditis bacteriophora (strain HP88) in heat, desiccation, ultraviolet tolerance, and host-finding ability was assessed by comparing the...
Gaugler, Randy, Molloy, Daniel
Laboratory bioassays showed that the susceptibility of Simulium vittatum to Neoaplectana carpocapsae increased with successive larval instars. First, second, and third instar larvae were resistant to...
Biological Control Potential of Neoaplectanid Nematodes
The neoaplectanids are among the most studied of all entomogenous nematodes. Because these nematodes kill their insect hosts, they are regarded as having excellent potential as biological control...
