Behavioral Responses of Two Parasitic Wasp Species with Different Degree of Host Specificity to Host-Related Plant Volatiles
(2013-11-08)
As an indirect defense to herbivore attack, plants release many types of volatile organic compounds (VOCs), which guide parasitoids to their herbivore hosts. Plants may release constitutive volatiles or synthesize new ones ...
Visual, Acoustic, and Volatile Cues to Improve Performance of Trapping Ambrosia Beetles (Coleoptera: Curculionidae)
(2013-11-11)
Three widely distributed species of ambrosia beetles (Coleoptera: Curculionidae: Scolytinae), Xylosandrus germanus Blandford, Xylosandrus crassiusculus Motschulsky, and Cnestus mutilatus Blandford are introduced pests that ...
Investigating Termite Behavior and Application Methods of Non-repellent Termiticides for the Control of Eastern Subterranean Termites (Isoptera: Rhinotermitidae)
(2014-05-09)
The effects of three non-repellent termiticides were evaluated in the laboratory against the eastern subterranean termites, Reticulitermes flavipes Kollar, to determine their efficiency in controlling this species. Treating ...
Influence of Endosymbionts in Mediating Plant Defense Responses to Herbivory by the Pea Aphid, Acyrthosiphon pisum
(2014-05-15)
Growing evidence suggests that symbiotic microbes that colonize different tissues and organs, known as endosymbionts, may influence the behavioral and physiological traits exhibited by insects as they interact with plants. ...
Production and characterization of Bt Cry1Ac resistance in bollworm, Helicoverpa zea (Boddie)
(2009-02-23)
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 ...
Mechanisms of Olfaction in Parasitic Wasps: Neurophysiological and Neuroanatomical Studies of Olfaction in a Specialist (Microplitis croceipes) and a Generalist (Cotesia marginiventris) Parasitoid
(2012-12-06)
The success of parasitic wasps (parasitoids) in controlling pest populations depends on their ability to locate their hosts in a complex olfactory environment. Parasitic wasps are known to utilize various types of host-related ...
Phenology of Pseudacteon spp. (Diptera: Phoridae) flies in Alabama
(2014-12-10)
Phorid flies, Pseudacteon spp. (Diptera: Phoridae), are one of many biological control agents of Solenopsis spp. (Hymenoptera: Formicidae) fire ants in their native South America. More than twenty species of phorid flies ...
Isolation and Assessment of Nitrogen-Fixing and Phosphate-Solubilizing Bacteria for Use as Biofertilizers
(2014-12-10)
Nitrogen and phosphorus are essential macronutrients for plant growth. The major sources of N and P in agriculture are chemical fertilizers. Nitrogen in the soil can be lost due to denitrification, leaching, and volatilization. ...
Biology and Management of Megacopta cribraria (Fabricius) (Heteroptera: Plataspidae): A Recent Invader to The United States
(2014-11-06)
Identified as both an agricultural pest of soybean and a residential nuisance pest, Megacopta cribraria (F.) (Heteroptera: Plataspidae), is a recently invasive pest species to the southeastern United States. Isolated to a ...
Factors Affecting Pre-Harvest Aflatoxin Contamination of Peanut (Arachis Hypogaea L.)
(2011-07-26)
Aflatoxin contamination of peanuts is one of the greatest concerns in peanut production throughout the world. Aflatoxin in peanut can be severe when plants are subjected to late season drought stress. Available carbon ...
