Humpback is not a fact that eats it =)

In this picture, she really isn't eating. But before that, I ate, pricked the inflorescence with my proboscis. But then she was afraid of me and flew to the leaf of a neighboring plant, where I captured her.

The same colony of aphids, with a staff of ants found in another place, in the city. And this is already interesting, because in the city blocks, where ragweed is most harmful to allergy sufferers (including me), for some unknown reason, even the ambergris leaf eater does not enter. I'll try to build it. Do you think that 70% alcohol will preserve it normally? Unfortunately, I don't know how to distinguish imagos (wingless females) from larvae.

Why do they have to be fake? Ants of the right species, especially Formica glauca, are highly polynomial in our ragweed growing areas, and under their supervision aphid colonies are well protected from most predators. If it were possible to identify a line of aphids that prefer ragweed, maintain it in artificial conditions in winter by accumulating a large number of female founders around May, and then release them (ideally from an airplane), then maybe something better would come out. Although, of course, not a fact. And our hogweed is found exclusively Siberian and then in small quantities. But your Sosnovsky hogweed looks cool, and if you don't wander naked in its thickets (I wonder who does this and why?), then it doesn't do any harm to humans. Only benefit for hymenoptera during flowering. And the cattle seem to eat it without negative consequences. Ragweed is a completely different matter: there is no benefit, even if it is accidentally eaten by cattle, it causes bitterness in milk, and the harm is enormous, there is simply nothing to compare it with from the flora of your region.

We've only got a shell here so far that we can try to cut it down. but it is dangerous. And the planes all "landed" back in the 14th. On the other side of the "demarcation line" is not particularly better, money is willingly allocated only for the war, oh, sorry, the ATO. And in science-except for the development of a new history of Ukraine from ancient times to the Paleolithic.
Which biomethods were successfully (more successfully than ours) developed by"conditional Americans"? Even with the unfortunate silver carp, which our poachers would have been happy to deal with long ago, just as the Chinese almost did with it at home, they can't do anything about it. I see success only in their biomethods for combating Europeans - the introduction of the Colorado potato beetle and the same ragweed (not counting small things like Canadian goldenrod, American white butterfly, etc.).

What kind of cows and what did the Americans go against? And most importantly-who gave the grade "excellent"? If you are against ragweed, then in the United States it does not pose a big problem at all, since due to natural causes it is in a rather depressed state. It is only in the black earth zone of Europe that ragweed has acquired an unprecedented ability to grow taller than a person and capture entire fields in continuous thickets.

As for the cultivation of entomophagous wasps, to be honest, I don't really believe in the effectiveness of this business, at least in our region of the world. It's just that specialists who study the OS, like everyone else, require a practical application, so you have to write something on this topic.

Last week I photographed another colony of aphids on ragweed, it seems that there are also imagos here:

picture: _____2016_069.jpg

This time the Lyaziuses were shepherds. The colony is quite powerful, covers a dense layer of one inflorescence, and has developed, at most, in two weeks. If there were a founder for every third inflorescence, then the effect on the amount of pollen and seeds produced, I think, would be significant. Unlike the same leaf beetle, which has already disappeared almost without a trace, and even the larvae are not visible. Oh, it's a pity that this type of aphid (if it really is Aphis fabae) also eats agricultural plants. Although if you" sow " aphids after harvesting, it could still have a significant effect, because the peak of ragweed flowering is the end of August and September.
