Evaluating biological control of fire ants using phorid flies: effects on competitive interactions
(Texas A&M University, 2002)
Our first objective was to assess the host specificity of the parasitic phorid fly, Pseudacteon tricuspis Borgmeier, in the laboratory against two ant species native to the United States, Solenopsis geminata (F.) þ S. ...
Stridulatory organ morphology, acoustics, and function in the red imported fire ant
(Texas A&M University, 2001)
The purpose of this research was to determine whether stridulation in the red imported fire ant (RIFA) serves a significant communicative function. Three general objectives were developed. 1) Characterize the stridulatory ...
Effects of red imported fire ant baits on some non-target ants
(Texas A&M University, 2002)
Laboratory tests were conducted to determine the effects of one-time baiting with commercially formulated red imported fire ant (RIFA) baits on worker mortality, egg production, and brood ranking of two non-target, competitor ...
Clinical mite infestations of domestic cats seropositive for feline immunodeficiency and/or feline leukemia viruses
(Texas A&M University, 2000)
Feline immunodeficiency virus (FIV) and Feline leukemia virus (FeLV) are both immunosuppressive viruses that compromise the ability of a feline host to combat foreign parhogens. Skin infections caused by parasitic mites ...
Revision of Neartic species in Opius (Gastrosema)(Hymenoptera:Braconidae:Opiinae)
(Texas A&M University, 2001)
A detailed analysis of intraspecific morphological variation and sexual dimorphism was conducted for seven Nearctic species in the subgenus Gastrosema Fischer. Results from the analysis are presented as a complete description ...
Tactical uses of Nylar® to manage ticks entering human habitation on dogs
(Texas A&M University, 2001)
The effect of Nylar[] against engorged larvae and nymphs of Amblyomma americanum, the lone star tick, Dermacentor variabilis, the American dog tick, and Rhipicephalus sanguineus, the brown dog tick was evaluated when applied ...
The phylogeny and classification of the Gronotoma group s.l. of genera (Hymenoptera: Figitidae: Eucoilinae)
(Texas A&M University, 2000)
Phylogenetic analysis of 96 morphological features and 1 biological feature reveal that the Gronotoma group of genera, as originally defined, is paraphyletic with respect to the remaining eucoiline genera. Thus, three new ...
Non-target effects of transgenic sugarcane on Parallorhogas pyralophagus (Marsh)
(Texas A&M University, 2002)
Parallorhogas pyralophagus (Marsh) is an important biological control agent of Eoreuma loftini Dyar, the key pest of Texas sugarcane. Transgenic sugarcane containing Galanthus nivalis agglutinin (GNA) was developed to deter ...
An investigation of key blow fly (Diptera:Calliphoridae) species of forensic importance occurring in Brazos and Burleson Counties of Central Texas
(Texas A&M University, 2001)
Forensic entomology makes use of an entomologist's knowledge about biology, insect taxonomy, and carrion ecology. This knowledge can be used as a tool to help investigators solve crimes. In order to use entomological ...
Early-season colonization patterns and biological aspects of natural mortality of the boll weevil (Coleoptera:Curculionidae) in central Texas cotton (Malvales:Malvaceae)
(Texas A&M University, 2001)
Border sprays have been suggested as an efficient alternative to whole-field insecticide applications for control of early-season infestations of the boll weevil, Anthonomus grandis grandis Boheman, in cotton, Gossypium ...
