Rapid mobilization of membrane lipids in wheat leaf sheaths during incompatible interactions with Hessian fly

Zhu, Lieceng; Liu, Xuming; Wang, Haiyan; Khajuria, Chitvan; Reese, John C.; Whitworth, R. Jeffery; Welti, Ruth; Chen, Ming-Shun (2012)

Hessian fly (HF) is a biotrophic insect that interacts with wheat on a gene-for-gene basis. We profiled changes in membrane lipids in two isogenic wheat lines: a susceptible line and its backcrossed offspring containing ...
Registration of twelve sorghum germplasm lines tolerant to greenbug feeding damage

Kofoid, Kenneth D.; Perumal, Ramasamy; Reese, John C.; Campbell, L. R. (2012)

The biotypic diversity of the greenbug [Schizaphis graminum (Rondani)] and development of lines with tolerance to greenbug feeding are ongoing concerns of sorghum [Sorghum bicolor (L.) Moench.] breeding programs in the ...
Reproductive diapause in Hippodamia convergens (Coleoptera: Coccinellidae) and its life history consequences

Michaud, J. P.; Qureshi, Jawwad A. (2006)

Adult Hippodamia convergens (Guerin) in reproductive diapause were collected from a spring cohort in western Kansas and held in pairs for the duration of their lives to assess female reproductive schedules under conditions ...
Resistance to multiple cereal aphids in wheat-alien substitution and translocation lines

Crespo-Herrera, Leonardo A.; Smith, C. Michael; Singh, Ravi P.; Åhman, Inger (2013)

Rhopalosiphum padi, Schizaphis graminum, and Sitobion avenae are three of the most destructive aphid species of wheat (Triticum aestivum L.). They can significantly reduce wheat yields directly by feeding and indirectly ...
Responses of the squash bug (Hemiptera: Coreidae) and its egg parasitoid, Gryon pennsylvanicum (Hymenoptera: Scelionidae) to three Cucurbita cultivars

Vogt, Elizabeth A.; Nechols, James R. (1993)

Laboratory experiments were conducted to quantify effects of resistant and susceptible host plants on the preimaginal and adult biologies of the squash bug, Anasa tristis (De Geer), and its egg parasitoid, Gryon pennsylvanicum ...
RNA interference revealed the roles of two carboxylesterase genes in insecticide detoxification in Locusta migratoria

Zhang, Jianqin; Li, Daqi; Ge, Pingting; Yang, Meiling; Guo, Yaping; Zhu, Kun Yan; Ma, Enbo; Zhang, Jianzhen (2013)

Carboxylesterases (CarEs) play key roles in metabolism of specific hormones and detoxification of dietary and environmental xenobiotics in insects. We sequenced and characterized CarE cDNAs putatively derived from two ...
RNA interference to reveal roles of β-Nacetylglucosaminidase gene during molting process in Locusta migratoria

Rong, Shuo; Li, Daqi; Zhang, Xueyao; Li, Sheng; Zhu, Kun Yan; Guo, Yaping; Ma, Enbo; Zhang, Jianzhen (2013)

β-N-acetylglucosaminidases are crucial enzymes involved in chitin degradation in insects. We identified a β-N-acetylglucosaminidase gene (LmNAG1) from Locusta migratoria. The full-length cDNA of LmNAG1 consists of 2667 ...
Role of House Flies in the Ecology of Enterococcus faecalis from Wastewater Treatment Facilities.

Zurek, Ludek; Scott, Harvey Morgan; Doud, C. W. (2014)

Enterococci are important nosocomial pathogens, with Enterococcus faecalis most commonly responsible for human infections. In this study, we used several measures to test the hypothesis that house flies, Musca domestica ...
Seasonal cycles of assortative mating and reproductive behaviour in polymorphic populations of Harmonia axyridis in China

Wang, Su; Michaud, J. P.; Zhang, Runzhi; Liu, Shuang; Zhang, Fan (2009)

1. We observed native populations of Harmonia axyridis (Pallas) around Beijing, China, over 2 years and performed choice and no-choice mating tests between melanic and succinic (non-melanic) beetles in the laboratory. 2. ...
Secrets of the "big bugs": special effects in 1950s science fiction movies

Cloyd, Raymond A. (2013)
Selection of reference genes for expression analysis in Diuraphis noxia (Hemiptera: Aphididae) fed on resistant and susceptible wheat plants

Sinha, Deepak K.; Smith, C. Michael (2014)

The Russian wheat aphid (RWA), Diuraphis noxia Kurdjumov, is a major global pest of wheat and barley production that causes enormous economic damage. Few studies have been conducted to explore and decipher the molecular ...
Sequential sampling for panicle caterpillars (Lepidoptera: Noctuidae) in sorghum

Elliott, N. C.; Brewer, M. J.; Giles, K. L.; Backoulou, G. F.; McCornack, Brian P.; Pendleton, B. B.; Royer, T. A. (2014)

Panicle caterpillars comprise an economically important insect pest complex of sorghum throughout the Great Plains of the United States, particularly in Kansas, Oklahoma, and Texas. The sorghum panicle caterpillar complex ...
Serine and cysteine protease-like genes in the genome of a gall midge and their interactions with host plant genotypes

Chen, Hang; Zhu, Yu Cheng; Whitworth, R. Jeffery; Reese, John C.; Chen, Ming-Shun (2013)

Proteases play important roles in a wide range of physiological processes in organisms. For plant-feeding insects, digestive proteases are targets for engineering protease inhibitors for pest control. In this study, we ...
Sexual activity diminishes male virility in two Coccinella species: consequences for female fertility and progeny development

Michaud, J. P.; Bista, Mahadev; Mishra, Geetanjali; Singh, Omkar (2013)

Male contributions, both chemical and behavioural, can influence female sperm usage and reproductive success. To determine whether such male factors are subject to depletion in Coccinella septempunctata and Coccinella ...
Significance of bacteria in oviposition and larval development of the sand fly Lutzomyia longipalpis

Peterkova-Koci, Kamila; Robles-Murguia, Maricela; Ramalho-Ortigão, Marcelo; Zurek, Ludek (2012)

Background : Microbial ecology of phlebotomine sand flies is not well understood although bacteria likely play an important role in the sand fly biology and vector capacity for Leishmania parasites. In this study, we ...
Sorghum seed maturity affects the weight and feeding duration of immature corn earworm, Helicoverpa zea, and fall armyworm, Spodoptera frugiperda, in the laboratory

Soper, Alysha M.; Whitworth, R. Jeffery; McCornack, Brian P. (2013)

Corn earworm, Helicoverpa zea Boddie (Lepidoptera: Noctuidae), and fall armyworm, Spodoptera frugiperda J.E. Smith, are occasional pests in sorghum, Sorghum bicolor L. Moench (Poales: Poaceae), and can be economically ...
Spatial pattern in aerosol insecticide deposition inside a flour mill

Campbell, James F.; Arthur, Frank H.; Zhu, Kun Yan (2014)

Aerosol insecticides are commonly used for management of stored-product pests inside food facilities, but the physical complexity of the interior of most food facilities may influence the dispersal and deposition of droplets ...
Suitability of pollen sources for the development and reproduction of Coleomegilla maculata (Coleoptera: Coccinellidae) under simulated drought conditions

Michaud, J. P.; Grant, Angela K. (2005)

Laboratory experiments compared the nutritive value of various pollen sources for the development of Coleomegilla maculata DeGeer under conditions of continuous water availability and simulated drought. When water was ...
Testing the importance of jasmonate signalling in induction of plant defences upon cabbage aphid (Brevicoryne brassicae) attack

Kuśnierczyk, Anna; Tran, Diem HT; Winge, Per; Jørstad, Tommy S.; Reese, John C.; Troczyńska, Joanna; Bones, Atle M. (2011)

Background: Phloem-feeding aphids deprive plants of assimilates, but mostly manage to avoid causing themechanical tissue damage inflicted by chewing insects. Nevertheless, jasmonate signalling that is induced by infestation ...
