TORONTO, May 20, 2013 /CNW/ - Toronto is currently dealing with an
infestation of the European Gypsy Moth (Lymantria dispar). Infestation levels reached a point where manual control methods, such
as egg scraping, sticky traps, and ground spraying of pesticides are no
longer effective in controlling the Gypsy Moth population.
The City of Toronto is planning two aerial sprays this week to control
outbreak populations of the European gypsy moth. The first spray day
will take place on Thursday, May 23 between 5 and 7:30 a.m. in the
seven Etobicoke spray areas listed below:
Humber Valley Golf Course
Valecrest Road and North Drive
Royal York Road and The Kingsway
Princess Margaret Boulevard - Kipling Avenue
The Kingsway - Edenbridge Drive
The second spray will take place on Friday, May 24 between 5 and 7:30
a.m. in the four spray areas listed below:
Cherry Beach Park
Toronto Island Park
Tam O'Shanter Golf Course
Spraying is dependent on weather and will only be done in the right
conditions. As a result, specific spray dates are chosen between 12 and
48 hours in advance, and can be cancelled if weather conditions change.
Residents within the affected spray zones are encouraged to check for
updates on the City's website at http://www.toronto.ca/trees/gypsy-moth.htm, or by calling 311(1-855-551-5150 if calling from outside Toronto).
A two-engine helicopter with an ultra low volume spray system will fly
about 15 to 30 metres above the tree tops during the application. Local
road closures will be in effect during the aerial spray to minimize any
potential risks associated with the low flying helicopter. Notification
signs will be posted along local roads to announce the closures.
The aerial pesticide spray application will apply Bacillus thuringiensis subspecies kurstaki (Btk) - (Product name: Foray 48B - Biological Insecticide Pest Control
Product (PCP) Act Registration Number 24977) to control Gypsy Moth outbreak populations and to help protect trees
from dying. This biological insecticide contains naturally occurring
bacterium found on dead or decaying matter in the soil. Btk, when used as directed and sprayed by air, is not considered a health
risk to humans.
The gypsy moth is a defoliating insect that is considered a major pest
in North America. The caterpillar, or larvae stage of the insect, eats
the leaves of trees, making the trees more susceptible to disease and
damage from other insects or weather related factors. Btk does not affect adult moths and butterflies, other insects, honeybees,
fish, birds or mammals. It kills young caterpillars that are present at
the time of spray. Through aerial spraying, Btk will be applied to the foliage of the trees and the caterpillars must
feed on the treated leaves for it to be effective.
The health and safety of residents and the health of the environment are
top priorities for the City of Toronto. No special precautions are
required for residents in the spray zone. However, if you wish to avoid
exposure to Btk, remain indoors during and immediately after the spraying. Residents
can also cover patio furniture or outdoor playing areas prior to the
spraying or hose them off afterward.
