we all have issues with our plants, what issues have you had this year and how did your rectify them (if at all)
For me, thrips, aphids and scale in small bursts, I leave them alone and they disappear, drosera, pings and byblis love thrips and massacre them.
Tadpoles from the white lip tree frog and common tree frog, they eat anything in the water, mainly hit my U.longifolia, uliginosa, bifida and aldrovanda (oddly not aurea or gibba), I like frogs so I moved them to one of my nymphaea ponds, the frogs also trample seedlings and break traps.
Cane Toads, they climb on my seedlings and have killed 3 byblis species and many drosera.
heat, not much I can do when it gets hot other than mist more frequently and run a fan.
Aquatic moth larvae, absolutely devastating and seem to be unstoppable.
Lemna invasions (I also gave up on stopping this)
A bench collapsed and claimed a few small neps as the rains washed out the soil and shifted it, countered it by changing my greenhouse floor from sand over gravel to road base with sand and then put a small divider from my greenhouse to the hill its on to funnel off excess water.

Mealybugs, mealybugs, mealybugs, and more mealybugs! (If anyone has a few suggestions on these that would be greatly appreciated, been using sevin but it only knocks them back)
Cutworms (love my coveted P. planifolia)
Water tray's drying out while out of town (Claimed a N. madagascariensis)

Also here, mealybugs appear, they go away with an insecticide that is pretty smelly, an organophosphorate don't remember the name. But my main menace are spodoptera worms, they camouflage black as the peat and eat all the drosera trichomes and if big enough, the whole leaf, aswell as little sarracenia.. Some frogs live here but they do nothing, and the cane frog lives on the ground. Then, if I had no greenhouse I would not have any sphagnum left, since yigüirro birds steal it all.

I think I have mealybugs on my cacti, but they don't slow down and nothing gets rid of the fuzz I find so I'm suspicious..... I get waves of thrips every now and then, a shot of orthene and they're gone. Also unfortunately got my first taste of mites on 3 different plants. Neem oil took care of them pretty quick though....

A flame thrower may be somewhat effective. One Do-It-Yourself pest control book said hot water will kill mealybugs. It recommended water between 90 and 120°F. A University of Hawaii test showed immersing the roots of plants infested with root mealybugs until the core of the root ball reached 115°F was 100% effective in killing the mealybugs with no harm to the plants. They've also used 120°F showers on plants which were very effective also. They followed up with a 1-2 minute cold shower to prevent damage to the plants. Only orchids and bromeliads. I tested a hot water spray (125°F) water in an ordinary hand spray bottle set to needle spray on Sarracenia and Drosera capensis that were infested with mealybugs. It appears to have been effective with no damage to the plants. The needle spray could reach into the hollows on the Sarracenia crown formed by the leaf bases. ucanr.edu/sites/UCNFAnews/Regional_Report_San_Diego_and_Riverside_Counties/Spring_2013__Hot_Water_Treatments_to_Control_Pests/

Would this same technique work for Scale and Thrips? Did the UH have a link to this research?

I should add that predacious fish (in particular gudgeon and beta's) are very effective against most aquatic threats/controlling mosquitos, the only thing they don't stop are aquatic moth, don't know why.
I use fish in my aldrovanda and utric ponds/tanks to great success, same with water scorpions and dragonfly larvae.
