To minimize the risk incursive spongelike moth pose to forests , farm , woodlet , and urban trees and to prevent the moths from becoming permanently established , the Ministry of Forests plans to carry out a spongy moth discourse programme in Courtenay during the spring .
Invasive spongy moths ( also cognise as Lymantria moths and formerly have it off as gypsy moth ) pose a danger to B.C. ’s ecosystems and economic system . Spongy moth caterpillars provender on tree leaf and have defoliated sections of forests and residential areas in Ontario and the eastern United States in late years . Should spongy moth become permanently established , trees such as Garry oak , arbutus , red alder tree , aspen , cottonwood , maple , orchard yield trees , nut Tree , and many species of urban decorative trees will be affected . Local pollinators that rely on these trees face up increased competitor from spongy moth Caterpillar for resources . Untreated spongy moths hazard spreading to other surface area of B.C. and are a threat to forest and farm .
Agricultural operation are at risk from spongy moth because the moth can affect solid food crop , such as apples , blueberries , and other fruits , as well as garden nursery product . Infested mathematical process are often capable to factory farm quarantines , as well as additional measure that may include product certification and increase pesticide use . Also , a lasting squishy moth population would demand B.C. agricultural and forest exportation to be dependent to restrictions at the U.S. border . These commodities would have to be scrutinise , possibly leave in delay or extra expense associated with the exportation of these production . Commercial and non - commercial-grade vehicle dealings into the U.S. could also be put out by a more thorough inspection regimen .
The 2022 monitoring program trapped a record number of spongy manlike moths throughout B.C. , with positive detections increase over the retiring two to three years across seven sites identify for treatment . This indicates that spongelike moth could become found in those location if the planned pesticide spray is not nail . The increase threat potentiality is tied to eruption in Ontario and Quebec during the past three years . testis masses are usually transported to B.C. on recreational vehicles and outdoor menage objects originating from unnatural areas outside of the state .
The treatment are planned for Victoria , Courtenay , Campbell River , and Port Alberni . The ministry is planning three treatments in the specified areas between April 1 and June 30 , 2023 .
The biological insect powder used in the treatment is Foray 48B. It is used in constitutive husbandry , and the fighting ingredient , Bacillus thuringiensis volt-ampere kurstaki ( Btk ) , is course present in urban , agrarian , and forest filth throughout the province . It only affect spongy moth caterpillars and is specific to their digestive systems .
The treatment has been sanction for the control of squishy moth larvae in Canada since 1961 . Repeat scientific study conclude the treatment personate no threat to the great unwashed . It does not harm mammals , birds , Pisces , plants , reptile , amphibious aircraft , bees , nor other insect . It affects spongy moth caterpillars once they have ingested the treated vegetation .
