One of threats that is rising and will continue to rise in next years will be emerging diseases.
Today's case is #Malaria outbreaks in cities of #Africa.
Ey. wait... in cities?
Yes parasite is carried by a invasive species of #Mosquito whose habitat is city and resistant to insecticides.
Something I learned a few years ago when a friend was infected by #NileVirus in #Sevilla
When supply networks are cut off or not available, people store water in ditches or pools. Mosquito larvae breed there

Dengue situation is worsening in Bangladesh 🇧🇩. But the govt. is yet to take any commendable action.

In the past 24 hours, 3,027 dengue patients were admitted to hospitals, as reported by the Directorate General of Health Services (DGHS). This year, dengue has tragically claimed the lives of 846 people, with nearly 173,795 individuals falling ill, marking it as the deadliest year since the first recorded epidemic in 2000.

Is a #mosquito bite really a bite? In Danish it's a sting... Which is it? 🤔

Also: It's outrageously out of proportion that a handful of mosquito bites can ruin a good night's sleep. I am #sleepless and very itchy.

Just heard the dread whine of a mosquito. Took a swipe at it, missed it. Tracked it to the corner of the ceiling, willed it to land ... a spider ambled out of a crack in the (wooden) ceiling and attended to it's prey. Excellent outcome. No more mozzie, spider got supper!

Tens of millions of #Americans are absolutely convinced that the multiple prosecutions of #Trump et al. are politically motivated, with no basis in actual crimes, and should be thrown out immediately on that basis. Many of them affect to believe that any #prosecution of a former #President should be off the table, because it’s “bad for #democracy” or “like something out of a third-world country” or some other content-free criticism. Most would of course cheerfully see #Biden thrown in prison for no provable #crime—but we know expecting consistency from them is a mug’s game.

Ithan Creek, PA

I needed to get out, so I did 😊

I spent a lot of time trying to take nice pictures while mosquitoes were hitting on me, although they did not bite thanks to DEET and permethrin-treated shirt 😀 Much better on the water, but on the trail, I basically needed to jog 😅

This creek runs along I-476, but once I am on the water, the freeway noises disappear, and all I can feel is a beautiful creek in the wood😊

De Havilland Mosquito TT.35. The last 'flourish' of the DH Mosquito was a post-war target tug, converted from the last bomber version built, the Mosquito B.35. This example hangs in the roof of one of the hangars at the Imperial War Museum, Duxford, United Kingdom, wearing the classic 'anti-camouflage' of the target tug, silver upper surfaces, with bold yellow and black stripes. The swift Mosquito was an ideal aircraft for towing aerial targets! There is no longer a flying example of the type in Europe, however, The People's Mosquito (a Registered Charity) is now building one!

Unnamed tributary of Darby Creek, PA

Mosquitos disappeared when I entered this cold tributary 😊

The water temperature was 3˚C (~6˚F) lower than that at its mouth (Darby Creek), where I was surrounded by many mosquitos even with DEET 😉

While it makes sense, it is a bit strange and very refreshing with cold water – I was wearing sandals 😊

Fallfish and Sunfish are active in Darby Creek, and Creek Cubs were found here.

This tiny tributary is covered by vegetation. This tributary feeds into Darby Creek and has much colder water than Darby Creek. This cold water plays a nice role as a mosquito repellent, once I entered this tributary, mosquitos were gone.

Almost all bites blow up to golfball-sized welts that are super painful. We have no standing water in the garden, no ponds etc, and yet you step outside for even just 30 seconds and there's a cloud around you.

Whatever #Edmonton is doing to control #mosquito population is definitely not working.

All our windows have intact screens, and yet you open the front door for a couple seconds and they come in

DH98 Mosquito B.35 This particular Mosquito represents the last bomber variant of the Mosquito, the B.35. Only two RAF Squadrons operated this type, both in the post-war period. However, they had a relatively short Service life as a bomber with many being converted as target tugs, designated TT.35. This Mosquito has since been moved to the RAF Museum's Bomber Hall. There are several Mosquitoes flying in the USA, and The People's Mosquito charity has just completed a set of fuselage moulds in the UK, as they begin to restore one of these beautiful aircraft to flight status. Please see www.peoplesmosquito.org.uk to learn more! #DeHavilland #DH98 #Mosquito #RAF #museum #WW2 #history #targettug #bomber #aircraft #restoration #aviation #photography #aviationphotography #RoyalAirForce #charity #avg #ThePeoplesMosquito #RegisteredCharity

“Scientists have found a naturally occurring strain of #bacteria which can help stop the transmission of #malaria from #mosquitoes to humans…

The bacteria works by secreting a small molecule, known as harmane, which inhibits the early stages of the malaria parasite growing in the #mosquito's gut…

Harmane can either be ingested orally by the mosquito, if mixed with sugar, or absorbed through its cuticle…

Malaria kills a child every minute.”

I just noticed that the Borough of Media, Pennsylvania, has a fantastic webpage urging residents to stop spraying pyrethroids on their yards (i.e., stop paying companies such as Mosquito Shield and Mosquito Squad to do it). The page also encourages people to report instances of pesticide drift from the target yard into neighboring yards. All towns should adopt a policy like this. #mosquito #mosquitoes #spraying #pesticides #pollinators #bees #insects #pyrethroids #delco #pennsylvania #BeeCityUsa

Mosquitoes and the disease they spread are a concern worldwide, especially in regards to invasive species that bring diseases less common in a region and those species that focus on biting humans.

A consortium of European researchers have come together to target the asian tiger mosquito by using RNA interference and food sources that the larva will take up, preventing their reproduction.

Ah, that explains the #mosquito bites. Checked the window screens finally, and one screen had detached from one side of the window screen frame.

So, since we had a really dry summer last year, I'm collecting water in rain barrels to water the garden and conserve our well-water. However, as I discovered recently, rain barrels can be places where mosquitoes can breed. So I put a thin layer of old olive oil (leftover from soap making) on top. I checked on both rain barrels today -- no #mosquitoes!

"Rain Barrels and Mosquito Pests

While using a rain barrel in the garden is great for water conservation among its other benefits, mosquitoes are a constant threat, as they carry life-threatening diseases. Learning how to control mosquitoes in a rain barrel is just as important to controlling them anywhere else, especially since the pests take advantage of standing water to help carry out their life cycle. Here are some things you can do to minimize their presence:

- Dish soap– Liquid dish soap creates a slick film on the surface of the water. When mosquitoes attempt to land, they drown before they have time to lay eggs. Use natural soap and avoid products with perfume or degreasers, especially if you water your plants with rain water. One or two tablespoons of liquid soap per week is plenty for most rain barrels.

- Mosquito dunks– Also known as mosquito donuts, mosquito dunks are round cakes of Bti (Bacillus thuringiensis israelensis), a naturally occurring bacteria that provides mosquito control in rain barrels as it slowly dissolves. However, it is safe for beneficial insects. Be sure the product label indicates the dunks are formulated for ponds because other types, which kill caterpillars, aren’t effective in water. Replace the dunks as needed. Check them after a hard rain.

- Vegetable oil– Oil floats on the surface of the water. If mosquitoes attempt to land, they suffocate in the oil. Use about a quarter cup of oil per week. You can use any type of oil, including olive oil. Horticultural oil or dormant oil are also effective for preventing mosquitoes in rain barrels."

So, how do I plan to solve this?

Well, #Klipper allows for the addition of the #RaspberryPi MCU, which works with my sensor.

I will then once again create the exact same #Mosquito #MQTT server as I had.

#Moonraker will then post this temperature to the server.

If I keep the format and everything identical, my #ESP32 will simply reconnect, and my heating lamps would work again perfectly.

It's just like 03:01 in the morning now, and if I start that now, I probably won't sleep tonight.

Finally, I installed #Moonrakerz the #API service for #Klipper.

My printer doesn't support a chamber natively, so I used the #EnclosurePlugin from #Octoprint to measure the enclosure temperature. I then modified the source code to take that sensors value and inject it as #Gcode that #Octoprint actually thought my printer was enclosed.

Using the #MQTTPlugin, this state was then communicated to a #Mosquito #MQTT server, which an #ESP32 then read and dimmed my heating lamps with a PID controller to get the enclosure up to 60°C.

The #EnclosurePlugin also controlled the power of my printer, visual lights, and then this sensor.

This is now obviously broken.
