Characteristics of an Introduced Walleye Population with Implications for Suppression

North American Journal of Fisheries Management, 2021
Abstract The management of introduced fishes, including Walleye Sander vitreus, whether for control or enhancement, requires understanding of population dynamics at the invasion front. Walleye recently established in the Pend Oreille basin, Idaho, threaten the existing salmonid-based fish community and associated recreational fishery ...

Habitat Management to Suppress Pest Populations: Progress and Prospects

Annual Review of Entomology, 2017
Habitat management involving manipulation of farmland vegetation can exert direct suppressive effects on pests and promote natural enemies. Advances in theory and practical techniques have allowed habitat management to become an important subdiscipline of pest management.

Suppression of a Field Population of Houseflies with Spalangia endius

Science, 1975
Sustained releases of the microhymenopteran pupal parasite Spalangia endius , at a commercial poultry installation in north Florida, completely suppressed a population of houseflies within 35 days.

Suppression of insect pest populations and damage to plants by vermicomposts

Bioresource Technology, 2005
The effects of commercial vermicomposts, produced from food waste, on infestations and damage by aphids, mealy bugs and cabbage white caterpillars were studied in the greenhouse. Vermicomposts were used at substitution rates into a soil-less plant growth medium, MetroMix 360 (MM360), at rates of 100% MM360 and 0% vermicompost, 80% MM360 and 20 ...

Imaging population dynamics of surround suppression in the superior colliculus

European Journal of Neuroscience, 2016
AbstractThe superior colliculus (SC) plays a key role in controlling spatial attention. It is hypothesized that some forms of spatial attention, such as the detection of a single salient object arise from lateral competitive interactions between different locations within the spatial map in the SC.

The polaroid suppression test in a pediatric population with ophthalmologic disorders

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2003
The Polaroid suppression test (PST) is a new method for early detection of amblyogenic factors by screening for suppression. The apparatus can elicit suppression with the use of Polaroid filters. The aim of the present study was to examine a population of children with known ophthalmologic disorders using the PST to determine the rate of false-negative

Salmonella Suppression by Known Populations of Bacteria in Flies

Journal of Bacteriology, 1969
Survivorship of Salmonella typhimurium, Streptococcus faecalis, Proteus mirabilis , and Pseudomonas aeruginosa was studied in dibiotic and tribiotic interactions in vitro and in various regions of the digestive tract of the blow fly, Calliphora vicina .

Distributing an Insect Population Suppressant from Aircraft

Transactions of the ASAE, 1981
ABSTRACT A system was developed for transporting, metering, and distributing a pelletized formulation of the Screwworm Adult Suppression System (a combination of bait and toxicant) from aircraft as a suppressant of a na-tive population of screwworm, Cochliomyia hominivorax (Coquerel). Two trials of 3 applications each at rates of 0.18 kg/km2 of pellets

The dexamethasone suppression test in an elderly population.

Biological psychiatry, 1983
Impaired suppression of plasma cortisol levels following a single midnight dose of dexamethasone has been well documented in a large subgroup of depressed patients. To interpret meaningfully this 24-hr dexamethasone suppression test in geriatric patients, the effect of age per se was examined by comparing the pattern and duration of suppression in ten ...
