Why are mosquitoes so bad in 2023?

Published

 on

Mosquitoes.

They’re thirsty bloodsuckers that annoy those who cross into nature, feasting on their salty life source while leaving behind red, itchy bumps.

And this year across Canada, it seems the pesky insects are worse than ever.

Those who’ve wondered about an increase in mosquitoes may be right, according to Laura Ferguson, assistant professor of biology at Acadia University in Nova Scotia.

“It’s definitely been a trend to some extent that people are noticing anecdotally,” she told CTVNews.ca in an interview on Friday. “New Brunswick, in particular, over the last couple of years, has noticed big bursts in mosquito populations, especially in this mid- to late spring.”

Why mosquitoes may be worse than normal in some areas has more than one answer.

WHY MOSQUITOES ARE SO BAD THIS YEAR

Ferguson works with a team to study mosquitoes, understand the different species and track their abundance across North America.

“It’s for a few different reasons why we’re seeing more mosquitoes than we may have at least in the past couple of decades or so,” she said.

The first contributing reason is that there are more species of mosquitoes than in years past.

Different species travel with human goods across the world. They then breed in their new homes, creating populations of specific types of mosquitoes where they’d never existed before.

“Here in Nova Scotia for instance, we didn’t have a (species) a couple of decades ago — it came over from Japan in tire, we think — and it’s just exploded across the province and you can find it anywhere now,” Ferguson said.

Additionally, Ferguson said, warmer winters caused by climate change allow mosquitoes that would die off in the winter to survive and continue reproducing.

Along with being able to survive the milder weather, some types of mosquitoes are able to reproducer faster in warm temperatures because of the type of insect they are. Ferguson says mosquitoes are ectotherms, meaning their regulation of body temperature depends on external sources like the sun.

Precipitation also plays a factor in how well mosquitoes can survive, because they lay eggs in stagnant water.

Ferguson said if it’s a particularly dry spring there may be fewer mosquitoes around, depending on the species. Others lay eggs in the fall, so there would only be a large drop in mosquitoes if the previous year was dry.

Another theory that needs more research, Ferguson said, is the waning effects of the chemical Dichlorodiphenyltrichloroethane (DDT), which was used in the past to control insects in crops, but was phased out in the 1970s due to its harm on other species.

Despite this, the chemical can still be found in water and is circulating in ecosystems.

“Those kinds of holdover effects from these really persistent insecticides may have also suppressed mosquito populations for a few decades,” she said. “And now we’re experiencing a bit of this rebound of these populations as these insecticides and their effects start to wear away in the environment.”

WHAT CAN BE DONE ABOUT MOSQUITOES?

Unfortunately, all these factors lead to an increase in mosquitoes, a problem without fast solutions.

“I think for the most part, what we need to do is just figure out the ways to protect ourselves from contact with mosquitoes because they are a part of the ecosystem,” Ferguson said.

“On a regular basis it’s going to be things like hanging out in a screened porch instead of right outside, making sure that you dump standing water anywhere in your yard.”

Using repellents like DEET and some natural oils can help when out in the woods, Ferguson said.

“Wear light colours, long sleeves, those kinds of things to reduce the area of your body that’s exposed to potential bites,” Ferguson said. “That kind of thing is sort of our best bet of that trying to sort of prevent our contact with them as much as possible.”

Canada’s Denis Shapovalov wins Belgrade Open for his second ATP Tour title

Published

 on

BELGRADE, Serbia – Canada’s Denis Shapovalov is back in the winner’s circle.

The 25-year-old Shapovalov beat Serbia’s Hamad Medjedovic 6-4, 6-4 in the Belgrade Open final on Saturday.

It’s Shapovalov’s second ATP Tour title after winning the Stockholm Open in 2019. He is the first Canadian to win an ATP Tour-level title this season.

His last appearance in a tournament final was in Vienna in 2022.

Shapovalov missed the second half of last season due to injury and spent most of this year regaining his best level of play.

He came through qualifying in Belgrade and dropped just one set on his way to winning the trophy.

Shapovalov’s best results this season were at ATP 500 events in Washington and Basel, where he reached the quarterfinals.

Medjedovic was playing in his first-ever ATP Tour final.

The 21-year-old, who won the Next Gen ATP Finals presented by PIF title last year, ends 2024 holding a 9-8 tour-level record on the season.

Talks to resume in B.C. port dispute in bid to end multi-day lockout

Published

 on

VANCOUVER – Contract negotiations resume today in Vancouver in a labour dispute that has paralyzed container cargo shipping at British Columbia’s ports since Monday.

The BC Maritime Employers Association and International Longshore and Warehouse Union Local 514 are scheduled to meet for the next three days in mediated talks to try to break a deadlock in negotiations.

The union, which represents more than 700 longshore supervisors at ports, including Vancouver, Prince Rupert and Nanaimo, has been without a contract since March last year.

The latest talks come after employers locked out workers in response to what it said was “strike activity” by union members.

The start of the lockout was then followed by several days of no engagement between the two parties, prompting federal Labour Minister Steven MacKinnon to speak with leaders on both sides, asking them to restart talks.

MacKinnon had said that the talks were “progressing at an insufficient pace, indicating a concerning absence of urgency from the parties involved” — a sentiment echoed by several business groups across Canada.

In a joint letter, more than 100 organizations, including the Canadian Chamber of Commerce, Business Council of Canada and associations representing industries from automotive and fertilizer to retail and mining, urged the government to do whatever it takes to end the work stoppage.

“While we acknowledge efforts to continue with mediation, parties have not been able to come to a negotiated agreement,” the letter says. “So, the federal government must take decisive action, using every tool at its disposal to resolve this dispute and limit the damage caused by this disruption.

“We simply cannot afford to once again put Canadian businesses at risk, which in turn puts Canadian livelihoods at risk.”

In the meantime, the union says it has filed a complaint to the Canada Industrial Relations Board against the employers, alleging the association threatened to pull existing conditions out of the last contract in direct contact with its members.

“The BCMEA is trying to undermine the union by attempting to turn members against its democratically elected leadership and bargaining committee — despite the fact that the BCMEA knows full well we received a 96 per cent mandate to take job action if needed,” union president Frank Morena said in a statement.

The employers have responded by calling the complaint “another meritless claim,” adding the final offer to the union that includes a 19.2 per cent wage increase over a four-year term remains on the table.

“The final offer has been on the table for over a week and represents a fair and balanced proposal for employees, and if accepted would end this dispute,” the employers’ statement says. “The offer does not require any concessions from the union.”

The union says the offer does not address the key issue of staffing requirement at the terminals as the port introduces more automation to cargo loading and unloading, which could potentially require fewer workers to operate than older systems.

The Port of Vancouver is the largest in Canada and has seen a number of labour disruptions, including two instances involving the rail and grain storage sectors earlier this year.

A 13-day strike by another group of workers at the port last year resulted in the disruption of a significant amount of shipping and trade.

The Royal Canadian Legion turns to Amazon for annual poppy campaign boost

Published

 on

The Royal Canadian Legion says a new partnership with e-commerce giant Amazon is helping boost its veterans’ fund, and will hopefully expand its donor base in the digital world.

Since the Oct. 25 launch of its Amazon.ca storefront, the legion says it has received nearly 10,000 orders for poppies.

Online shoppers can order lapel poppies on Amazon in exchange for donations or buy items such as “We Remember” lawn signs, Remembrance Day pins and other accessories, with all proceeds going to the legion’s Poppy Trust Fund for Canadian veterans and their families.

Nujma Bond, the legion’s national spokesperson, said the organization sees this move as keeping up with modern purchasing habits.

“As the world around us evolves we have been looking at different ways to distribute poppies and to make it easier for people to access them,” she said in an interview.

“This is definitely a way to reach a wider number of Canadians of all ages. And certainly younger Canadians are much more active on the web, on social media in general, so we’re also engaging in that way.”

Al Plume, a member of a legion branch in Trenton, Ont., said the online store can also help with outreach to veterans who are far from home.

“For veterans that are overseas and are away, (or) can’t get to a store they can order them online, it’s Amazon.” Plume said.

Plume spent 35 years in the military with the Royal Engineers, and retired eight years ago. He said making sure veterans are looked after is his passion.

“I’ve seen the struggles that our veterans have had with Veterans Affairs … and that’s why I got involved, with making sure that the people get to them and help the veterans with their paperwork.”

But the message about the Amazon storefront didn’t appear to reach all of the legion’s locations, with volunteers at Branch 179 on Vancouver’s Commercial Drive saying they hadn’t heard about the online push.

Holly Paddon, the branch’s poppy campaign co-ordinator and bartender, said the Amazon partnership never came up in meetings with other legion volunteers and officials.

“I work at the legion, I work with the Vancouver poppy office and I go to the meetings for the Vancouver poppy campaign — which includes all the legions in Vancouver — and not once has this been mentioned,” she said.

Paddon said the initiative is a great idea, but she would like to have known more about it.

The legion also sells a larger collection of items at poppystore.ca.
