Laboratory-selected Bt-resistant colonies are important tools for elucidating Bt resistance mechanisms and helping to determine appropriate resistance management strategies for Bt crops. Here, two laboratory populations ...
Recruitment to and Defense of Aphids by Fire Ants and Native Ants and an Estimate of Their Trophic Positions Using Stable Isotopes
The red imported fire ant, Solenopsis invicta, is an invasive ant known to form facultative mutualisms with aphids. Fire ants significantly reduce the abundance of aphid predators and herbivores on plants infested with ...
Developing Alternatives to Methyl Bromide: A Focus on Acrolein (2-Propenal)
Methyl bromide, a soil fumigant with biocidal action, is used in agriculture to control weeds, fungi, bacteria, nematodes, and arthropods. Due to methyl bromide’s active role in atmospheric ozone depletion, its usage will ...
Studies on the Biology and Host Location Behavior of Pteromalus cerealellae (Ashmead) (Hymenoptera: Pteromalidae), A Parasitoid of Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae)
Pteromalus cerealellae is an ectoparasitoid of several pests of stored products. Information on several aspects of its biology and life history strategy is grossly lacking. My dissertation focuses on some aspects of the ...
The Effect of Cover Crops on Suppression of Nematodes on Peanuts and Cotton in Alabama
Cover crops were evaluated in the greenhouse and in field locations to determine their host status and nematode suppressive effect on root-knot nematodes, Meloidogyne incognita and M. arenaria and the reniform nematode, ...
The Armored Scale Insects of Alabama (Hemiptera: Diaspididae)
This thesis presents the most complete and up-to-date survey available for the armored scale insects of Alabama. Prior to this survey, the most current survey list available was completed in 1994 and included records of ...
