Trap results show that the spring 2015 Surrey-Delta gypsy moth spray program was successful.
No European gypsy moths were found in Delta treatment area. Only two moths in two separate traps were found within the Surrey treatment area.
As a result, no followup treatment is required for Surrey and Delta in 2016. However, further higher-density trapping will occur in the Surrey area to determine what kind of treatment program may be necessary in future years in Surrey.
During spring 2015, 4,576 hectares around 64th Ave. and 176 St. in Surrey, and 204 hectares between Highways 10, 99 and 91 in Delta were sprayed with Foray 48B. Foray 48B contains Bacillus thuringiensis var kurstaki (Btk), which is naturally present in urban, forest and agricultural soil throughout the province.
Every year federal and provincial staff use specialized traps and other survey methods to determine if gypsy moths are in an area – and whether or not they can be eradicated. While every year some gypsy moth populations are found in B.C., so far none have become permanently established.
The gypsy moth is an introduced pest species. The caterpillars feed on tree leaves and can damage forests, farms and orchards. In recent years,Llrge gypsy moth populations have defoliated sections of forests and residential areas in Ontario and the eastern U.S.A.
The moths are unintentionally brought to B.C. on vehicles and equipment from eastern North America. Infested locations are often subject to agriculture and transportation quarantines, as well as additional treatments. Abatement measures may include vehicle checks, product certification and increased pesticide use.
