Africanized Honey Bee, Erin W. Hodgson, Cory A. Stanley, Alan H. Roe, Danielle Downey

All Current Publications

African honey bees (Apis mellifera scutellata) are native to sub-Saharan Africa and were introduced in the Americas to improve honey production in the tropics. These African honey bees were accidentally released and began to interbreed with European honey bees (Apis mellifera ligustica), the most common subspecies used for pollination and honey production in the United States (Fig. 1). As a result, the hybrid offspring are called “Africanized” because of their shared characteristics. Africanized honey bees are about the same size, shape and color as European honey bees (Fig. 2), and a genetic analysis must be used to distinguish one from …

Selective Biochlorination Of Hydroxyquinolines By A Flavin-Dependent Halogenase, Fuchao Xu, Amanda Merkley, Dayu Yu, Jixun Zhan

Biological Engineering Faculty Publications

Rdc2 is a flavin-dependent halogenase from Pochonia chlamydosporia. Through the introduction of a His₆-tag to both the N- and C-termini, the isolation yield of Rdc2 from Escherichia coli using Ni-NTA affinity chromatography was increased by three-fold. In vitro reaction of Rdc2 and a flavin reductase (Fre) with seven different hydroxyquinolines revealed that 3-hydroxyquinoline (3), 5-hydroxyquinoline (5), 6-hydroxyquinoline (6), and 7-hydroxyquinoline (7) can be specifically halogenated. These products were prepared by incubating the corresponding substrates with IPTG-induced E. coli BL21(DE3)/Rdc2. They were respectively characterized as 3-hydroxy-4-chloroquinoline (3a), 5-hydroxy-6-chloroquinoline (5a), 5-chloro-6-hydroxyquinoline (6a), and 7-hydroxy-8-chloroquinoline (7a) by NMR and MS …

Cat-Facing Insects, Diane Alston, Michael Reding, Marion Murray

All Current Publications

There are a number of insects with the piercing-sucking feeding habit that can cause deformity and catfacing type injury to pome and stone fruits, including lygus bug, stink bug, and boxelder bug. Cat-facing injury is caused by puncture feeding in flower buds and fruit. The result is unsightly dimpling, deformity, and scarring of fruit. The name “cat facing” comes from the distorted fruit shape that resembles the puckered cheeks of a cat. In addition to the insects discussed in this section, some aphids and the campylomma bug can inflict similar injury.

Chinch Bugs, Kelly Kopp, Ryan S. Davis, Ricardo A. Ramirez

All Current Publications

Chinch bugs are “true bugs”. In Utah, the common chinch bug [Blissus leucopterus leucopterus (Say)], and western chinch bug (Blissus occiduus) may feed on turfgrass, especially under conditions of severe heat and drought. Coupled with under-irrigation, direct sunlight, and thick thatch, chinch bug numbers can soar from mid-summer to early fall.

Measuring Relationships Between Camp Staff And Camper Developmental Outcomes: An Application Of Self-Determination Theory, Mark F. Roark, Gary D. Elis, Mary Sara Wells, Ann Gillard

Kinesiology and Health Science Faculty Publications

While recent studies have suggested that positive developmental outcomes may result from participating in camp experiences, it is unclear what specific aspects of camp (e.g., staff dispositions, counselor teams, non-counselor staff) might influence these camper outcomes. Previous studies have measured the autonomy support of schoolteachers and found that more autonomy-supportive dispositions that, for example, engage autonomy, relatedness, and competence through the use of meaningful choice or rationale have positive effects on student developmental outcomes (e.g., intrinsic motivation, competence, self-esteem). Unlike schools, camps are noncompulsory recreation environments and most are outdoor-based. The existence of differences between the physical, social, and motivational …

Food Habits Of Wintering Waterfowl On The Great Salt Lake, Utah, Josh L. Vest, Michael R. Conover

Wildland Resources Faculty Publications

Two invertebrates, brine shrimp (Artemia franciscana) and brine flies (Ephydridac), occur in great densities in the Great Salt Lake (GSL) but it is unknown whether ducks forage extensively on them during winter or rely on freshwater food. Common Goldeneye (Bucephala clangula), Northern Shoveler (Anas clypeala) and Green-winged Teal (Anas crecca) were collected from the GSL during winters 2004–05 and 2005–06 to evaluate their food habits. Brine shrimp and brine flies comprised more than 70% of the winter diet of these ducks. Common Goldeneyes consumed mainly brine fly larvae (68% based on dry weight biomass), which live primarily along the substrate. …
