Well, Washington is the ideal place for them to spread. Miles and mile of wilderness, where they won't be caught. They will decimate native wasps, and probably native bees, birds, and will kill more people. Also, honeybees kill native bees indirectly. These hornets will kill them directly, giving them no chance whatsoever. They aren't fluffy little bunnies(which by the way do cause trouble in many places)

Hi there! I went on a 6 month or so hiatus, in part due, and in part cause of the death of my colonies. 

However, I went back to the Sierras, and restarted my collection, which is now as follows:

Aphaenogaster uinta, Camponotus vicinus, Camponotus modoc, Formica cf. aserva, Formica cf. micropthalma, Formica cf. manni, Formica subpolita, Formica cf. subaenescens, Lasius americanus, Manica invidia, Pogonomyrmex salinus, Pogonomyrmex sp. 1, Solenopsis validiuscula, & Solenopsis sp. 3 (new Sierra variant).

AHHHHHHHHHHHHHHHHH, how many times do I have to say this, they pose minimal threat to native bees. Wasps, maybe, birds, maybe, people, maybe, (if they're stupid) but they certainly won't wipe the population away. Answer me this, how come there are plenty of wasps and bees and birds in their native habitat? They haven't evolved any defenses, so why haven't these "murder hornets" wiped out all life in Asia? They will simply be another minor predator, unless you're a European honey bee.

We don't know how much of a threat they will pose to native bees. Those species in their area have lived around them for millennia they know how to act, the bees and wasps here don't. Just look at Polistes dominula. They push away native species. And they are nowhere near as bad as these.

They attack bumblebees and several are endangered and threatened in the USA, particularly the northwest states.  Maybe you should research them a bit more.  i already found pics of them killing bumblebees.

We don't know, but we can surely guess with a lot of confidence. Bees there, like I said, don't react in any special way. They are nearly identical in terms of behavior to our bees. there's no special anti-hornet behaviors or chemicals or anything possessed by the majority of Asian natives.

besides my whole point is they will ruin our agriculture, alot of our produce comes from the northwest, sonoma, monterey county, etc.  they use european honeybees to pollinate stone crops because its nice and cool and they do best in that climate.

  the wasps pose a threat to US.  at this point either way, bees are gonna die, but importing japanese honeybees is the lesser loss.  sorry man, it's a lose-lose situaiton regardless, but i'd rather lose less than MORE.

All wasps are predatory, remember that. Simply because they are found eating bumblebees doesn't mean they are a major threat. All wasps will hunt down smaller insects than them if possible, flying insects being a favorite small prey item. Asian hornets are larger and thus will view any passing bumblebee as potential prey. Spiders and birds eat bumblebees too, are they decimating the populations? As for locating hives, yes, scent. They fly out and smell honeybee hives, which have a very strong smell due to the sheer amount of resources inside, all lying out in the open with little protection. Honeybees live underground with minimal wax and honey, just enough to sustain the colony. Entrance tunnels can be up to a few feet long. I think that's more than enough to smother the majority of the scent.

Native bees can pollinate too. The loss of honeybees will provide a temporary setback but native bees can easily fill that role. Keep in mind many agricultural products actually depend on native bees and are incapable at the present moment of being sustained by honeybees. Importing japanese honey bees may boost the economy but the relationship between native bees and plants as a major pollinator will collapse. I think the environments more important.

that's FALSE you're thinking of the alfalfa bees .  Our farms DEFINITELY use european honeybees to pollinate their crops- they get honey to sell, good pollinators.  I'm sorry man but your inability to consider the problems they pose to us right now in our weakened state with farms in serious trouble already terrifies me.

  I don't agree with importing Japanese honeybees. Just look at all the examples where when you introduce an invasive to get rid of an invasive. I just don't think it is a good idea, as we have many historical examples of this going wrong.  Just look at the cane toad in Australia. Of course, I don't think that Japanese honeybees would be anywhere near that bad, but it's something to think about.

Yes, we use them, no, we don't need, them. And I'm not talking about alfalfa bees. Look at squash bees for instance. One of the best pollinator of gourds and solely reliant of said plants. If you were to remove that role as a squash pollinator, there goes the bee, and the plant is worse off. Oftentimes they pollinate every single squash flower so quickly that the honeybees that do happen to visit by chance are simply there for taking the nectar and pollen, and don't help with pollination at all. I quote from https://nature.berke...-California.pdf "we found that native bees often make up a high proportion of the total bee visits (i.e., visits that include honey bees), suggesting that native bees can be as or more important than managed honey bees for these crops" and "In watermelon, a crop that requires multiple bee visits and deposition of 500–1,000 pollen grains for production of a marketable fruit, we found that the native bee community alone could provide sufficient pollination for the crop. This ability, however, depended on the diversity and abundance of bees in the community, which in turn was dependent on the abundance of native habitat in the area." Examples where honey bees are completely obsolete include "crops typically thought of as “self-pollinated” benefited substantially from native bee visitation. Tomato flowers produce no nectar, and their pollen can only be accessed from poricidal anthers by high frequency vibration. Honey bees are unable to vibrate the flowers, and thus obtain few rewards from tomato flowers (hence the low proportion of honey bee visits, as shown in Table 1). However, bumble bees and other bees (e.g., Anthophora urbana) can obtain the pollen through vibration, and can often be found exploiting this honey bee-free niche." This ties in with the environment itself and the preservation of native plants. "California’s native bees make an important contribution to crop pollination. This contribution could become even more valuable as an “insurance policy” if honey bees become more scarce or fail altogether. We have also shown that all of these native bee species occur in wild habitats and show some degree of dependence on the native California flora. Finally, the destruction of native habitat in the Central Valley appears to be related to a decline in the diversity and abundance of native bees found there, along with a concomitant reduction in the crop pollination services they provide." As https://plants.usda....Pollinators.pdf states, "Native bees, however, significantly contribute to crop pollination – and, in some cases, provide all of the pollination." However this is slightly off topic. The point is that honey bees are not at all required for pollination.

Well, Washington is the ideal place for them to spread. Miles and mile of wilderness, where they won't be caught. They will decimate native wasps, and probably native bees, birds, and will kill more people. Also, honeybees kill native bees indirectly. These hornets will kill them directly, giving them no chance whatsoever. They aren't fluffy little bunnies(which by the way do cause trouble in many places)

AHHHHHHHHHHHHHHHHH, how many times do I have to say this, they pose minimal threat to native bees. Wasps, maybe, birds, maybe, people, maybe, (if they're stupid) but they certainly won't wipe the population away. Answer me this, how come there are plenty of wasps and bees and birds in their native habitat? They haven't evolved any defenses, so why haven't these "murder hornets" wiped out all life in Asia? They will simply be another minor predator, unless you're a European honey bee.

 

Actually its ignorant of you to think that they pose minimal threat to native bees. 

 

Animals that evolved living around these hornets obviously adapted to survive with them over the course of thousands of years. It's not rocket science, anyone should be able to figure that out. Japanese bees will swarm and cover single hornets, cooking them alive, as an effective defense strategy.

 

Solenopsis invicta live with plenty of diverse wildlife in the Pantanal. if they're so devastating in the US and Australia, why haven't they wiped out life in South America and destroyed countless amounts of infrastructure? What about Argentine Ants? What about the Burmese Pythons introduced to Florida?

 

^That's how you sound. Invasive species are unrecognizable to native populations. Army ants, for instance, would wipe out almost all the life in tropical countries where they don't currently exist because native animals didn't evolve dealing with such a threat. If no animals ever evolved a response to predators (natural selection), they would have all died out, and therefore the predators would have too, meaning they wouldn't exist today. But obviously that isn't the case.

 

 

The same applies here, the hornets wouldn't kill off entire bee populations obviously, that's very very unlikely, but the fact that you're saying they pose minimal threat doesn't make sense.

 

Through the food web, certain things will prevent one species from ever truly becoming dominant. When they are put in an environment where there is nothing stopping them from becoming dominant, they ruin the food web. I'm sure you know that though.

Yes, this is on the right track. never import other species to solve problems created by importation in the first place. We imported weasels to a rabbit infested island to control the rabbit population, imported by humans, and now the native birds are nearly wiped out. Or how about cane toads? Cane toads were originally meant to consume beetles, which in fact were imported by humans in the first place. Now they decimate native animals through competition and outright predation.

No, no no. Honey bees evolved that response to direct targeting as a preferred food item. Most native Asian bees are at most picked off one by one as a simple small boost in larval protein. The Burmese python isn't a threat in its native habitat because things will eat it, while it has no predators in it's invaded areas. Nothing ever evolved to specifically ward off them. Argentine ants are so destructive because invasive populations came from a minimal amount of ancestors, thereby causing massive super colonies. In their natural habitat infighting keeps population under control. As for the red imported fire ant, the animals here were simply not prepared for it. They came from jungles, which are the most diverse terrestrial habitats and therefore the most competition intense. Residents there were equally aggressive and thus able to compete successfully. In that case it isn't the ant itself but the environment in which it developed. Think of it as having a major league player being moved to play against some schoolkids. Native animals didn't need to defend themselves because they naturally had evolved to be equally aggressive from environmental factors.
