1. Vyavhare, Suhas. Establishing and Implementing an IPM Program for the Redbanded Stink Bug: An Emerging Soybean Pest in the Southern Region.

Degree: 2014, Texas A&M University

Redbanded stink bug (RBSB), (Piezodorus guildinii Westwood) has recently emerged as an economic pest of soybean, Glycine max (L.) Merrill in the southern US. Having only recently emerged as a pest in the US, little information exists on RBSB in this country. Information on RBSB life history is needed to provide the basis for development of an effective management plan for this Neotropical pentatomid. This dissertation research was undertaken to gather information which will help achieve the long term goal of developing an integrated pest management (IPM) program for RBSB. Soybean field surveys conducted over three years across the Upper Gulf Coast of Texas showed that RBSB has become the most abundant stink bug species attacking soybean in this region, accounting for 65% of the entire population of the stink bug pest complex. Field cage experiments showed that highest yield losses from RBSB occurred when soybeans at R5-R6 stages were infested. Our data also showed that a relatively high RBSB density (8 RBSB adults/0.3 m) during R4-R5 stage soybean triggered development of delayed maturity indicated by green leaf retention. In addition, field experiments conducted to determine if reduced pod load or alteration of sink-source ratio is involved in delayed maturity showed no relationship between reduced pod load and occurrence of soybean delayed maturity. However, RBSB density was found to have a significant positive correlation to the occurrence of soybean delayed maturity. These findings suggest that RBSB-induced soybean delayed maturity may not be solely due to reduced pod load or altered sink-source ratio, but additional mechanisms also may be involved. Finally, results from an insecticide field trial and laboratory bioassays showed that RBSBs are more susceptible to neonicotinic and pyrethroid insecticides than to the widely used organophosphate, acephate. This dissertation research has provided valuable information in regard to RBSB and soybean, which will help develop, and establish an IPM program for this emergent pest of US soybean. Development of an IPM program will reduce dependence on chemical insecticides for RBSB management. Reductions in insecticide use will eventually benefit the environment and human health.

2. Costa, Rafael de Farias. The impacts of improving Brazil's transportation infrastructure on the world soybean market.

Degree: 2009, Texas A&M University

The lack of adequate transportation infrastructure in Brazil has been a bottleneck for the soybean producers for many years. Moreover, the costly inland transportation incurred from this bottleneck has resulted in a loss in competitiveness for Brazil compared to other exporting countries, especially the United States. If transportation costs are reduced by introducing improved infrastructure, Brazil is expected to increase its competitiveness in the world soybean market by increasing its exports and producer revenues. On the other hand, the United States and other significant soybean competing exporting countries are expected to lose market share as well as producer revenues. This study uses a spatial equilibrium model to analyze transportation infrastructure improvements proposed by the Brazilian government vis-?-vis enhance the nation?s soybean transportation network. The analyzed transportation improvements are: (i) the development of the Tapaj?s-Teles Pires waterway; (ii) the completion of the BR- 163 highway; (iii) the construction of the Mortes-Araguaia waterway; (iv) the Ferronorte railroad expansion to Rondon?polis and the linkage between the city of Rio Verde to Uberl?ndia; and (v) the Ferropar railroad expansion to the city of Dourados. The model specifies the Brazilian inland transportation network and the international ocean shipments. The model divides Brazil into 18 excess supply regions and 8 excess demand regions. The competing exporting countries are the United States, Argentina, Rest of South America (Bolivia, Paraguay, and Uruguay), Canada, and India. The importing countries are composed of China, European Union, Southeast Asia, Mexico, and the Rest of the World. Results suggest these proposed transportation improvements yield potential noteworthy gains to Brazil with producer revenues increasing more than $500 million and exports increasing by 177 thousand metric tons. Consequently, the world soybean price declines by $1.16 per metric ton and producer revenues and exports in the United States fall by 63 thousand metric tons and $104.89 million, respectively. Although the absolute gains in price, revenues, and exports for Brazil are considerable, they only represent in relative changes 1.48, 2.35, and 0.32 percent, respectively. Similarly, the loss in price, revenue, and export value for the United States is also low, declining by 0.23, 0.23, and 0.12 percent, respectively. Advisors/Committee Members: Rosson, III, C.

3. Carpenter, Alexandra Cathryn. Wheat interactions with Italian ryegrass; forage production and quality in pure and mixed stands of wheat, oats, and ryegrass; and halosulfuron interaction with soils.

Degree: 2007, Texas A&M University

A growth room experiment compared seedling growth after nine weeks of two wheat genotypes in pure cultures and mixtures with Italian ryegrass at a low phosphorus (P) level and the P level recommended by soil testing. At the recommended P level in both pure and mixed culture, Mit, a semi-dwarf genotype, had a greater height, leaf area, tiller number, and dry weight of leaves, stems and roots than did Kharkof, a landrace. These results reflected the visual selection criteria for seedling vigor and tillering used in the initial development of the semi-dwarf cultivars. Field experiments compared total dry matter, calories, and percent crude protein and acid detergent fiber of oats, wheat, and ryegrass in pure culture and mixtures at four locations in central Texas at first clipping, second clipping, and unclipped. Although, forage yield was lower for the first clipping than the second clipping or the unclipped treatment, the first clipping had the best forage quality. There was a strong environmental influence on yield and quality. The best forage was pure wheat at College Station, pure ryegrass at Marlin, the wheat-ryegrass mixture at Temple, and pure oats at Thrall. Since Temple had the greatest yield of any site, the wheat-ryegrass mixture demonstrated the highest yield potential. The soil adsorption characteristics of halosulfuron was examined using six soils. Soil adsorption of halosulfuron appeared to be a function of organic matter. Low Kf,ads values indicated that a relatively high plant availability of halosulfuron could be available for plant uptake. Sorghum produced in soils with a low organic matter content may experience injury because of the high plant availability. Advisors/Committee Members: Cralle, Harry T. (advisor), Borlaug, Norman E. (committee member), Bovey, Rodney W. (committee member), Chandler, James M. (committee member), Miller, Travis D. (committee member), Senseman, Scott A. (committee member).
