Gypsy Moth Trapping Results in 2006

Results of Canadian Food Inspection Agency's Annual Monitoring and Ministry of Forest and Range's Mass Trapping

In the summer of 2006, 153 male moths were caught in 72 pheromone traps at 15 locations listed below:

BC Interior: (total = 1 moth)
Grand Forks (1)

Lower Mainland: (total = 5 moths)
Harrison Lake (1), Chilliwack (1), White Rock (1), Delta (Annacis Is.)(2)

Vancouver Island: (total = 147 moths)
Saanich (3), Courtenay (39), Sidney (22 - mt), Colwood (7), Lake Cowichan (1), Mill Bay (1), Ladysmith (6), Nanaimo (1), S. Cedar Hill (32 - mt), Saltspring Island (35 - mt). 

mt =  High density mass trapping grids (trap density at 9 traps/ acre or 5760 traps/sq.mi., inter-trap distance 70 ft). 

Mass trapping efforts on on Gabriola Island and Duncan show very promising results.  Moths were not trapped in either mass trapping grid this summer following dramatic reductions in catches in 2004 to  2005.  The mass trapping grid in Sidney resulted in the recovery of a non-viable (unfertilized) egg mass (see the alternative treatment page).  

Egg masses searches have been completed with the discovery of viable (fertilized) egg masses in Saanich (Cedar Hill Golf Course) (4 egg masses), and Belmont Park (1).  

More details on the proposed treatments are available on the Treatment Status page.
