In the spring of 2009, forestry officials determined that an outbreak of gypsy moth larvae in wooded areas on the west side of the city of London, Ontario, Canada was severe enough to warrant a spraying program to control the moths (1). The areas of concern are in close proximity to residential suburbs. The gypsy moth Lymantria dispar ( L.) is an invasive species introduced to North America in the 1860s from Europe. After mating the female moth lays her eggs in one, buff coloured mass that…

Study of Bacillus thuringiensis 4ant strain for warm blood animals

There is inhibited growth of the normal microflora in the large intestine of warm-blooded animals under the influence of oral and dermal administration of the strain Bacillus thuringiensis 4ant at a dose of 100 mg/kg body weight.

Safety of Bacillus thuringiensis var. kurstaki applications for insect control to humans and large mammals.

Btk is considered by most people to be the safest bioinsecticide available at present and is registered for use against many species that are pests in agriculture, forestry and horticulture.

Aerial spraying Bacillus thuringiensis kurstaki (Btk).

This article critically evaluates the conclusion of no health hazards that usually accompanies Aerial Spraying of Bacillus Thuringiensis Kurstaki (Btk) ticide that does not pose hazards for humans.

Secondary Effects of the Pesticide Bacillus thuringiensis kurstaki on Chicks of Spruce Grouse (Dendragapus canadensis)

Reduced growth during the first 2 weeks of avian development has important consequences at the population level, and it is recommended that this secondary effect be considered for all species who rely on Lepidoptera larvae as a food resource prior to wide spread application of B.t.k. for insect control.

Bacillus thuringiensis (B.t.) is a live microorganism that kills certain insects and is used to kill unwanted insects in forests, agriculture, and urban areas.

B.t.T. is less toxic to mammals and shows fewer environmental effects than many synthetic insecticides, however, this is no reason to use it indiscriminately and its environmental and health effects must be thoroughly considered before use.

Public health implications of the microbial pesticide Bacillus thuringiensis: an epidemiological study, Oregon, 1985-86.

Bacillus thuringiensis var. kurstaki (B.t.-k) is a microbial pesticide which has been widely used for over 30 years. Its safety for a human population living in sprayed areas has never been tested.

Increase in human antibody levels following exposure to Bt products have been reported but there was no increased incidence in asthma or other illness, and Bt insecticides have an excellent safety record.

Symptom complaints following aerial spraying with biological insecticide Foray 48B.

Aerial spraying with Foray 48B is associated with some adverse health consequences in terms of significant increases in upper airway, gastrointestinal, and neuropsychiatric symptoms, as well as a reduction in overall perception of health in the exposed population.

The Effects of Aerial Spraying with Bacillus thuringiensis Kurstaki on Children with Asthma

This is the first paper to address the issue of whether or not aerial spraying with Btk has a harmful effect on children with asthma and no evidence of adverse effects from the use of the biological pesticide was found.
