Pilot project of Bacillus thuringiensis against western spruce budworm in central Montana, 1981

Creator:: Stipe, Lawrence E., Niwa, Christine G., Eder, Robert G., Gibson, Kenneth E., and Meyer, Hubert E.
Abstract:: Cooperative Forestry and Pest Management conducted a pilot control project in central Montana to determine the effectiveness of two commercial formulations of BaaiUus th,uringiensis Berliner applied at 8 billiori international units (BIU) per acre (19.8 BIU per hectare) when used under operational conditions against the western spruce budworm, Choristoneu:roa ocaidentalis...

Dipel wettable powder (Bacillus thuringiensis Berliner) as a control agent for western spruce budworm Choristoneura occidentalis Free

Creator:: McGregor, Mark D., Hamel, Dennis R., Lood, Rudolph C., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Dipel (R) was applied by helicopter to three blocks of Douglas fir and Engelmann spruce infested with Choristoneura occidentalis Free., in southwestern Montana. Dosage was 1 pound (7.2 Bill) in 2 gallons of water/acre (453 g in 7.5 t/0.4 ha). A commercial surfactant, Bio-film (R) was added at the rate...

Western spruce budworm 1/ control project on the Big Timber Ranger District, Gallatin National Forest, Montana

Creator:: Bousfield, Wayne E., Cifala, Frank, Kracht, Richard, and United States. Forest Service. Northern Region
Abstract:: The microbial insecticide, Bacillus thuringensis (Bt), was applied from fixed-wing aircraft to approximately 700 acres of western spruce budworm host type at the rate of 12 billion international units (BIU's) per gallon of water per acre. The objective of this control project was foliage protection to insure future cone production...

Effects of Dipel wettable powder for foliage protection against western spruce budworm 1 and 2 years following aerial application

Creator:: Bousfield, Wayne E., Flavell, Thomas H., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: This evaluation showed that Bt provided measurable foliage protection 1 year after treatment, but no differences were evident after 2 years. We recommend future Bt tests include postspray population measurements in the pupal and/or adult, and/or egg stage, and that foliage protection be measured the following year. The effects of...

Interactions and persistence of the mosquitocidal bacteria Bacillus sphaericus and Bacillus thuringiensis var. israelensis

Creator:: Donegan, Katherine K.
Abstract:: Interactions between Bacillus sphaericus and Bacillus thuringiensis israelensis (Bti), persistence of insecticidal activity in the mosquito habitat, and suitability of enzyme-linked immunoabsorbent assay (ELISA) for detecting and quantifying bacterial endotoxin in the mosquito habitat were investigated. Interactions between the two bacterial species were examined by laboratory and field bioassays with...

Biochemical studies on the mosquitocidal delta endotoxin of Bacillus thuringiensis subsp. israelensis

Creator:: Pollock, Martin L.
Abstract:: The cytolytic properties of the mosquitocidal 25 Kd protein deltaendotoxin of Bacillus thuringiensis subsp. israelensis (Bti) was studied using the human erythrocyte as a target cell. Both a fixedtime and a kinetic hemolytic bioassay were developed in order to screen a variety of treatments for their influence on the toxinerythrocyte...

Development of an enzyme-linked immunosorbent assay to detect antibodies against Bacillus thuringiensis subspecies israelensis in Mallard ducks (Anas platyrhynchos)

Creator:: Rutherford, Gregory J.
Abstract:: To develop an assay to detect antibodies to Bacillus thuringiensis subsp. israelensis in mallard ducks, a growth curve was first established for the bacterium. The growth curve indicated that the crystal delta endotoxin would be best harvested from the rest of the cell material after 12 hours of growth. The...

A reevaluation of 1978 aerial Bacillus thuringiensis Berliner (Bt) applications for cankerworm control in Siberian elm shelterbelts

Creator:: Hard, John S. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: 1. Defoliation by cankerworms in 1979 was significantly less in 1978 treated shelterbelts than in untreated shelterbelts. 2. Most shelterbelts treated in 1978 retained enough foliage by late June 1979 so that adjacent crops were protected from wind. 3. Aerially applied Bt at a rate of 1/2 lb./acre provided shelterbelt...
