    • Effects of dietary components on diet consumption, reproductive allocation and larval development of the boll weevil, Anthonomus grandis 
      Hilliard, Richard Ala (Texas A&M University. Libraries, 1983)
      The effects of varying dietary nitrogen, lipid and sucrose on diet consumption, nutrient utilization and reproductive allocation were studied in the female boll weevil, Anthonomus grandis (Coleoptera:Curculionidae). ...
    • Growth model of greenhouse tomatoes with carbon dioxide enrichment : development and experimental tests 
      Kano, Atsushi (Texas A&M University. Libraries, 1985)
      A deterministic, compartmental growth model of greenhouse tomato plants, written in Pascal computer language, was developed based on a leaf assimilation model and a model of a theory that the photosynthesis rate is controlled ...
    • The Influence of Trickle Irrigation on the Quality of Irrigation Return Flow 
      Brown, K. W.; Gerard, C. J.; DeMichele, D. W.; Sharpe, P. J. H.; Hipp, B. W. (Texas Water Resources Institute, 1976-03)
      The influence of trickle irrigation on the quality of irrigation return flow was investigated in a field study and by means of computer simulation models. Six undisturbed buried monolith lysimeters were utilized to quantify ...
    • An Investigation of the Return Flow from Irrigated Land 
      Brown, K. W.; Gerard, C. J.; DeMichele, D. W.; Sharpe, P. J. H.; Hipp, B. W. (Texas Water Resources Institute, 1974-09)
      Recent trends in agricultural have lead to the intensification of crop production in areas with long growing seasons and ample solar radiation. Unfortunately, these areas also often have limited water supplies, and the ...
    • Mathematical models for predator-prey interactions 
      Rao, Chennupati Raghavendra (Texas A&M University. Libraries, 1976)
      In the study of population dynamics, the predator-prey system is recognized as a vitally important aspect in natural population control. Some aspects concerning the predator-prey interactions are studied in this dissertation. ...
    • A model of metabolizing sinks in plants 
      Keener, Melvin E. (Texas A&M University. Libraries, 1977)
      The basic objectives of this study was to build a model that describes the physiology of sinks. This also includes the process of unloading assimilates from the phloem. The metabolic steps necessary to describe a typical ...
    • Modeling seasonal development of the sorghum midge, Contarinia Sorghicola (Coquillett) 
      Baxendale, Frederick Pau (Texas A&M University. Libraries, 1983)
      Two separate temperature-dependent models were formulated which described spring emergence from overwintering and development of nondiapausing generations of the sorghum midge, Contarinia sorghicola (Coquillett) (Diptera: ...
    • Techniques for modeling phenological development of weed populations 
      Bridges, David Curtis (Texas A&M University. Libraries, 1987)
      Research was conducted to formulate techniques for modeling phenological development of weed populations. Techniques which are currently used for modeling development rate of insect populations were reviewed and tested for ...
