DUCHESS OF DIRT: Brown marmorated stink bugs have reached the Comox Valley

Published

By Leslie Cox

Special to the Record

Thanks to all the wonderful readers who contacted me with sightings of the brown marmorated stink bug in their homes, on their decks, climbing the sides of their houses. I think it is safe to say the BMSBs are here in the valley. Ugh. Now what?

Well, we definitely need to think of doing something to control these pests because they are known to feed on more than 100 plant species. And since the BMSBs are native to Asia, there are not many predators here who will keep them in line.

RELATED: With the colder weather, beware of bugs seeking comfort indoors

No major beneficial insects to keep the BMSBs in check led to an estimated $37 million loss to the apple industry in the Mid-Atlantic States in 2010, so states a page on a Government of BC website titled “Brown Marmorated Stik Bug (BMSB) Pest Alert.” No mention of how large the apple industry is overall but a $37 million loss sounds significant.

Unfortunately, their appetite is not strictly for apples though. They also love pears, peaches, grapes, all kinds of berries, chokecherry, vegetables (including corn and tomatoes), hazelnuts, almonds, English holly, maple, box elder, white ash, catalpa, and buckthorn. I would hazard a guess there are likely even more plant species the BMSBs could develop a hunger for in their new country.

Thankfully, reproduction is not as prolific in North America when you compare one or two generations per year versus as many as six generations per year in their native Asia. But one gets the full scope of a population explosion when a single female BMSB can lay as many as 400 eggs in a summer and the second generation of females add their 400 eggs to the tally in the same season. Not as bad as the aphid reproduction numbers, but still robust enough.

As some readers have discovered, the adult BMSBs prefer warm, dry conditions where they can overwinter in comfort. As soon as the temperatures start to drop and daylight hours decrease, you may find these unwelcome house guests making themselves quite comfortable. They will not do any damage to your home, but evicting them can be daunting if there are enough of them. You certainly do not want to squish them or vacuum them up…or you will soon discover why they are labeled “stink bugs.” Not something you want to expose yourself to if you are sensitive to odours.

There is some good news, though. A species of parasitic wasp was found feasting on BMSB eggs in Chilliwack four years ago. Properly identified as Trissolcus japonicus, this wasp has managed to follow its favourite food source from its native Asia to Canada. Quite appropriately, this wasp is commonly called the Samurai wasp.

And according to the Government of BC website, ladybugs, lacewings and spiders will also feed on BMSB eggs. There may be some hope BMSBs will not become too unruly a pest.

Not so the American bullfrog, though. Just put another notch in my belt with the recent capture of yet another one in our pond. It was a decent size – about four inches from nose to butt. Definitely reproduction age but a male because of its yellow throat.

I suspect it was a late migration addition from the field pond behind us that made the mistake of doing a little sunbathing amongst the pond lilies on a nice afternoon when I spied him. Water was cold enough to slow his reactions though. Either that or my stalking skills with the butterfly net are getting quite good.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
