Work Summary

Public health entomologist and Integrated Pest Management (IPM) advocate working on pests that impact human health, and IPM in the built environment.

Research Interest

Dawn H. Gouge, PhD, is a Specialist and Professor at the University of Arizona, College of Agriculture and Life Science, Department of Entomology. Dr. Gouge is well established in the U.S. as a community Integrated Pest Management expert and works with international partners in several countries. Dawn has published 38 original research papers and more than 80 extension publications, many in collaboration with investigators from around the world, authored 4 book chapters and co-edited a definitive Pest Management Strategic Plan. Dr. Gouge is a frequent presenter at national and international meetings, and serves as a steering committee organizer of the International IPM Symposium conference. Dawn has received11 awards for outstanding achievement and provides service on both National and Federal advisory committees. Dr. Gouge has led the charge in establishing higher pest management standards in children’s environments, reducing risks associated with pest and pesticide exposure.

Abstract:

In laboratory bioassays Steinemema riobrave Cabanillas, Poinar and Raulston (355 strain), S. carpocapsae (Weiser) (Mexican 33 strain), S.feltiae (Filipjev) (UK76 strain), and Heterorhabditis bacteriophora Poinar (HP88 strain) infected and killed the subterranean termite, Heterotermes aureus (Snyder). Steinemema carpocapsae, S. riobrave and H. bacteriophora successfully reproduced in H. aureus and infective juveniles (IJs) exited the termite cadavers successfully. However, no progeny were produced by S.feltiae. IJs of S. carpocapsae formed two distinct size groups. The average total body length for the smaller group was 299.5 μm (S.E. 4.8), the average total body length for the larger group was 545.6 μm (S.E. 6.0). Small S. carpocapsae IJs infect, reproduce and form normal size IJs after subsequent infection in Galleria mellonella L. S. riobrave and H. bacteriophora showed a more gradual recovery in IJ size that needed 2 infection cycles in G. mellonella. In termite mortality tests, the progeny of small IJs of S. carpocapsae are comparably effective to the normal size IJs, under the conditions tested. After 72-h S. riobrave IJs from stock cultures (reared in G. mellonella) caused higher termite mortality compared with IJs cycled through termites then G. mellonella, then applied to termites. © The Society of Nematologists 2008.

PMID: 8583125;Abstract:

Steinernema feltiae is the most effective nematode for controlling sciarid species but S. carpocapsae does exert some control. S. feltiae is less effective at 30°C than at 22°C. S. anomali, S. riobravis and two Heterorhabditis spp. gave better control at the higher temperature. All six sciarid species tested were susceptible to S. feltiae but there was some variation in the level of infection. UK isolates of S. feltiae were more effective against UK sciarids than the nematode isolates from other European countries which were tested. Adult sciarids are infected by S. feltiae and can disperse nematodes to nematode-free compost.
