Pest Management Plan on Ecocentric

Today I am hosting Ecocentric a local environmental program and we are discussing our Pest Management Plan. This News blog is for people to check out the correspondence between myself and interior health regarding an interview, also the links they sent me along with some other interesting links. Please read the next post in my news feed to read more in depth my story about the Pest Management Plan.

Here is the correspondence via E mail with Interior Health:

Hi Christina,

Still working on this request – our potential spokespeople for this issue are busy with the flooding situation across the region right now but I do hope to have an answer for you later tomorrow.   

LESLEY COATES, M.A.

Promotion and Prevention Communications Officer

Interior Health

Thanks Lesley,

Just let me know if anyone is available for Tuesday July 3rd for about a 5 min interview.

I understand its a busy time.

All the best,

Christina

Thanks for your interest in having an IH person on your show. Most of your questions are quite specific and beyond the scope and practice of Interior Health (such as assessing the safety of methoprene and environmental assessments). These questions are best directed to other government agencies such as Health Canada and the Ministry of Environment. As such, we are declining the interview but we will provide you a statement about the intent and purpose of the IH Pest Management Plan. I will also provide you with some links to resources that will should help with your questions about methoprene.

Just working on tracking down a couple resources and will get this information to you tomorrow.

Thanks for your patience.

This is the official Statement I received on the topic:

Interior Health PMP

Interior Health (IH) is one of many agencies in the interior that have a pest management plan (PMP) for mosquito control.  Many local governments have their own PMP in place for nuisance mosquito control and/or West Nile virus control. IH does not apply larvicides under their own PMP – the intent of the Interior Health PMP is to provide areas within the Interior Health region that currently do not have their own pest management plan the ability to undertake mosquito larviciding should West Nile virus (WNv) be anticipated in a localized area. Interior Health’s PMP is not for nuisance mosquito control.

The Interior Health PMP was developed in 2009, the year West Nile virus was first detected in the Interior Health region. Evidence over the past three years has not demonstrated a substantial increase in WNv prevalence or a substantial increase in human risk.  In fall 2011, a provincial committee conducted a review of West Nile virus activity across BC. The review concluded that pre-emptive mosquito larviciding is not presently warranted as a precautionary risk reduction measure against human West Nile virus infection and outbreaks. As such, Interior Health is not recommending pre-emptive larvicing as a West Nile Virus prevention measure at this point.

Interior Health, in conjunction with BC Centre for Disease Control, will continue to carry out WNv surveillance. Medical Health Officers review the surveillance information on an ongoing basis and would determine if larviciding for West Nile virus risk reduction is necessary.

In BC, the Integrated Pest Management Plan process is overseen by the Ministry of Environment using the Integrated Pest Management Act and Regulation.  http://www.env.gov.bc.ca/epd/ipmp/regs/index.htm

Assessing the safety of pest control products (such as methoprene) and conducting environmental assessments are not within the scope of Interior Health’s responsibility.  It is the responsibility of the Health Canada’s Pest Management Regulatory Agency (PMRA).  An environmental assessment was done as part of the PRMA registration process.  More information is located here http://publications.gc.ca/collections/Collection/H113-18-2007-1E.pdf under section 2.4.

A fact sheet on methoprene is also available on the Health Canada website:  Use of Methoprene in Mosquito Contol Programs http://www.hc-sc.gc.ca/cps-spc/pubs/pest/_fact-fiche/methoprene/index-eng.php

Here is some real information on Methoprene and West Nile Spraying:

CONCERNING! READ REGARDING OUR BEES!!!

This was just lovely of Interior health to send me some Internet links on Methoprene one of them just stuck right out for me…this is the reevaluation report by the pest management regulatory agency (the one responsible for making sure this product is safe!!!)

Here is a little excerpt out of the report that is shocking to me:

2.4.2 Environmental Toxicology
2.4.2.1 Terrestrial
Methoprene showed no immediate acute effects on adult honeybees, as their mortality after 48 h did not exceed 10% after topical or oral application of the doses tested (up to 1000 μg/bee). At 250 μg/bee, some studies have shown behavioural changes, developmental abnormalities and disruption of hormonal regulation over periods ranging from 1 to 21 days. These effects were not seen at 25 μg/bee. Earthworms showed little if any toxic effects to methoprene exposure. Methoprene is practically non-toxic to mallard ducks and bobwhite quail on both an oral and dietary basis (lethal dose 50% [LD50] > 2000 mg/kg, lethal concentration 50% [LC50] > 10 000 mg/kg). Acute LD50s for rats and dogs range from 5000 to 34 600 mg a.i./kg; therefore,
methoprene is classified as being practically non-toxic. Mammal dietary NOELs range from 20 to 250 mg/kg bw/day. Methoprene showed little phytotoxicity to flowering plants, peas and tomatoes.
