Entomopathogenic Nematodes Combined with Adjuvants Presents a New Potential Biological Control Method for Managing the Wheat Stem Sawfly, Cephus cinctus (Hymenoptera: Cephidae).

Autor: Scott L Portman, Sindhu M Krishnankutty, Gadi V P Reddy

Publikováno v: PLoS ONE, Vol 11, Iss 12, p e0169022 (2016)

The wheat stem sawfly, (Cephus cinctus Norton) Hymenoptera: Cephidae, has been a major pest of winter wheat and barley in the northern Great Plains for more than 100 years. The insect's cryptic nature and lack of safe chemical control options make th

Tritrophic Interactions Between an Invasive Weed (Lepidium latifolium), an Insect Herbivore (Bagrada hilaris), and a Plant Pathogenic Fungus (Albugo lepidii)

Autor: Scott L. Portman, Paul D. Pratt, Nastaran Tofangsazi, Brian N Hogg

Publikováno v: Environmental Entomology. 48:1317-1322

Perennial pepperweed, Lepidium latifolium L. (Brassicales: Brassicaceae), is an invasive weed that can form dense stands and displace native species. Bagrada hilaris Burmeister (Hemiptera: Pentatomidae) is a serious economic pest of Brassicaceae vege

Host plant defense produces species-specific alterations to flight muscle protein structure and flight-related fitness traits of two armyworms

Autor: Gary W. Felton, Scott L. Portman, James H. Marden, Rupesh R. Kariyat

Publikováno v: The Journal of experimental biology. 223(Pt 16)

Insects manifest phenotypic plasticity in their development and behavior in response to plant defenses, via molecular mechanisms that produce tissue-specific changes. Phenotypic changes might vary between species that differ in their preferred hosts

Advancing Biological Control of the Wheat Stem Sawfly: New Strategies in a 100-yr Struggle to Manage a Costly Pest in the Northern Great Plains

Autor: Gadi V. P. Reddy, Scott L. Portman, Stefan T. Jaronski, David K. Weaver

Publikováno v: Annals of the Entomological Society of America. 111:85-91

For more than 100 yrs, the wheat stem sawfly (WSS) Cephus cinctus Norton (Hymenoptera: Cephidae), has been a destructive pest of cereal crops in the Northern Great Plains. WSS infestation levels >70% have been reported, and economic loss from crop da

Host plant water deficit stress impairs reproduction and development of the galling fly (Parafreutreta regalis), a biological control agent of Cape-ivy (Delairea odorata)

Autor: Patrick J. Moran, Scott L. Portman, Kyra E. Santa Cruz

Publikováno v: Biological Control. 156:104555

Drought leading to water deficit stress is known to reduce performance of galling insects. The shoot tip-galling fly Parafreutreta regalis has been released for biological control of Cape-ivy (Delairea odorata) in California. Lack of moisture during

Cascading effects of host plant inbreeding on the larval growth, muscle molecular composition, and flight capacity of an adult herbivorous insect

Autor: Scott L. Portman, Rupesh R. Kariyat, James H. Marden, Michelle A. Johnston, Andrew G. Stephenson

Publikováno v: Functional Ecology. 29:328-337

Summary A primary function of adult winged insects is dispersal. Limiting larval dietary intake (partial starvation) has been shown to affect the flight muscle metabolism of adult moths reared on artificial diet, but a more ecologically relevant ques

Fecundity ofLarra bicolor(Hymenoptera: Crabronidae) and Its Implications in Parasitoid: Host Interaction with Mole Crickets (Orthoptera: Gryllotalpidae:Scapteriscus)

Autor: Robert McSorley, J. H. Frank, Scott L. Portman, Norman C. Leppla

Publikováno v: Florida Entomologist. 92:58-63

Larra bicolor F. (Hymenoptera: Crabronidae) is a specialist parasitoid of Scapteriscus (Orthoptera: Gryllotalpidae) mole crickets, attacking adults and medium to large nymphs. Reproductive systems were dissected from 10 female wasps collected in nort
