(Texas A&M University. Libraries, 1979)This dissertation presents a general method of optimizing simulated systems and demonstrates the procedure for maximizing the single period benefits of an entrepreneur. The method is applied to the problem of maximizing ...
-
(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). ...
-
(Texas A&M University. Libraries, 1986)Research was conducted to quantify volatile compounds emanating from the flower buds of seven cotton (Gossypium hirsutum L. ) cultivars at two planting location, to determine the influence of the volatiles on boll weevil ...
-
(Texas A&M University. Libraries, 1979)Interactions of cotton genotypes, planting patterns, irrigation levels, and insecticide treatments were examined separately and in combination in split-pot experiments to determine if certain combinations could be used to ...
-
(Texas A&M University. Libraries, 1984)Cotton bollworm interactions were studied on selected Upland cotton cultivars in 1981-83 at Corpus Christi, Texas. Neonatal bollworm, Heliothis zea (Boddie), larvae were confined on cotton plants for seven days in whole ...
-
(Texas A&M University. Libraries, 1985)Infestations of Anthonomus grandis Boheman (Coleoptera, Curculionidae) were found on staminate Hampea nutricia Fryxell (Malvaceae) trees throughout central Tabasco, Mexico. Pistillate fruiting forms were sometimes punctured ...
-
(Texas A&M University. Libraries, 1976)The dispersal from initial residence locations of such insects as the Mexican boll weevil is an important factor in their persistent existence. Insects and other small organisms dispersed from a point of initial concentration ...
-
(Texas A&M University. Libraries, 1983)A mathematical model that describes the population dynamics of a cotton crop and the boll weevil is discussed. A system of partial differential equations forms the model's core. A finite-difference solution procedure is ...
-
(Texas A&M University. Libraries, 1982)Fruit development of Upland cotton cultivars in three maturity groups (based on time of boll opening) were evaluated at two planting dates and two planting densities to determine the components contributing to early fruit ...
