Development of a Pest Management Plan - Nuisance Mosquito Control
The purpose of this Pest Management Plan (PMP) No. 700-0003-2011/2015 is to reduce overall mosquito annoyance within the Corporation of Delta and the Tsawwassen First Nation by controlling larval development using an Integrated Pest Management (IPM) approach to control. The PMP focuses on larval mosquito control initiatives and uses public education, physical site modification and biological controls to reduce larval mosquito populations. The PMP also conserve natural mosquito predators wherever possible and includes the use of non-persistent, bacterial larvicides.
The proposed duration of the PMP is from 15 April 2011 to 31 December 2015. Larvicide products proposed for use include Vectobac 200G, which contains the natural-occurring soil bacterium Bacillus thuringiensis var. israelensis, (PCP #18158) and VectoLex CG (PCP # 28008) made with the related bacterium Bacillus sphaericus. Both of these products provide species-specific control of mosquito larvae and are non-toxic to other organisms including fish, birds, wildlife, man and domestic animals. This PMP will replace Delta's previous PMP that expires in 2011. No substantive changes from the existing PMP are being considered in the development of this PMP.
Mosquito larvae require stagnant or non-flowing waters, temporary or permanent, to develop. Development habitats include salt marshes and freshwater marshes, ponds and ditches. When physical alterations (draining, filling) are neither practical nor desirable, developing larvae will be treated using VectoBac 200G or VectoLex larvicides. Total area for larvicide treatment is not to exceed 50 hectares of public lands in each year of the PMP. Applications of Vectobac 200G and VectoLex CG will be made using ground-based, hand-broadcast methods. All applications will be conducted within the Corporation of Delta and Tsawwassen First Nation lands.
This Pest Management Plan is being prepared for the Corporation of Delta and Tsawwassen First Nation by D.G. Regan and Associates Ltd., an environmental services firm with extensive experience in pest management plan development and local mosquito control operations.
