Associations between Wolbachia, maize and Diabrotica virgifera virgifera
(University of Missouri--Columbia, 2008)Diabrotica virgifera virgifera which is infected with Wolbachia, is the most significant and widespread pest to maize in North America and Europe. Wolbachia are obligate intracellular bacteria which seem to be limited to ... -
Characterization of the insect cuticle sclerotization hormone bursicon and bursicon-regulated genes in the house fly Musca domestica
(University of Missouri--Columbia, 2008)Bursicon is a neurohormone that regulates the cuticle sclerotization and wing expansion process in insects. Bursicon is a heterodimeric cystine knot protein containing two subunits, burs [alpha] and burs [beta], which are ... -
Evaluating flood tolerance measures for Missouri oak species
(University of Missouri--Columbia, 2008)The aim of this research was to determine the effects of four flooding treatments on survival of seedlings from 45 seedlots of seven oak species at two sampling dates using logistic analysis, and to quantify growth responses ... -
Fatty acid variation between forage species and within populations and fatty acid content of beef finished on pasture with different forage species
(University of Missouri--Columbia, 2008)We describe two experiments; the first experiment was conducted in a greenhouse where four forage species - orchardgrass (Dactylis glomerata L.), tall fescue [Lollium arundinaceum (Schreb.) S.J. Darbysh = Schedonorus ... -
Molecular characterization of genetic resistance to soybean cyst nematode in soybean line SS97-6946
(University of Missouri--Columbia, 2008)Soybean Cyst Nematode (SCN) (Heterodera glycine) is the most damaging pest of soybean and estimated annual yield losses are 1.5 billion dollars in USA. Breeding resistant cultivars is the most efficient means to control ... -
Novel approaches in macroinvertebrate biomonitoring
(University of Missouri--Columbia, 2008)The increasing popularity of benthic macroinvertebrate use for biological monitoring and assessment of lotic systems calls for new applications for regions with a lesser known fauna and an overall better understanding of ... -
Recommendations for tree establishment in tall fescue-based silvopasture
(University of Missouri--Columbia, 2008)Silvopasture offers Midwest landowners the opportunity to plant trees in their pastures without significant loss of forage production. However, much of the pasture in the Midwest is dominated by tall fescue (Schedonorus ... -
Reflectance sensors to predict mid-season nitrogen need of cotton
(University of Missouri--Columbia, 2008)Nitrogen (N) is an essential nutrient for cotton production; consequently there is a tendency to over-apply nitrogen. High N causes excessive vegetative growth and delayed crop maturity, which result in increased cost in ... -
The role of genetic and phenotypic diversity in maize and its effects on aflatoxin accumulation by the fungus Aspergillus flavus
(University of Missouri--Columbia, 2008)Accumulation of the potent carcinogen, aflatoxin, in maize poses a significant health risk to humans and animals. Most commercially grown maize lines are susceptible to infection by the fungus that synthesizes aflatoxin, ... -
The semiaquatic heteroptera (Gerromorpha) of Thailand : faunistics, biogeography and phylogeography
(University of Missouri--Columbia, 2008)Semiaquatic heteropterans (Gerromorpha) were collected from mountain streams and waterfalls and lowland ponds adjacent to the mountains were collected from 2002 to 2006. One hundred fifty-eight species representing 31 ... -
The sublethal effects of methoxyfenozide on the field orientation and courtship behavior of Cydia pomonella (Linnaeus) (Lepidoptera: tortricidae)
(University of Missouri--Columbia, 2008)The sublethal effects of ecdysone agonist methoxyfenozide on the mating behavior and field orientation of codling moth, Cydia pomonella (Linnaeus), was examined. Five different lure types were placed in the upper canopy ...
