Lichtenstein has established the fact that from the egg of the Aphis of Pistachio galls, Anopleura lentisci, is hatched an apterous insect (the gall-founder), which gives birth to young Aphides (emigrants), and that these, having acquired wings, fly to the roots of certain grasses (Bromus sterilis and Hordeum vulgare), and by budding underground give rise to several generations of apterous insects, whence finally comes a winged brood (the pupifera).
Two forms of foul brood have been long known, one foul smelling, the other odourless; and investigations made during 1906 and 1907 showed that the etiology of the disease is not by FIG.
When the view commenced to gain ground that whitebait were largely young herring, the question arose whether or not the immense destruction of the young brood caused by this mode of fishing injuriously affected the fishery of the mature herring.
It has been held by some, however, that the first brood corresponds to the sporophyte generation of the higher plants, and that the rest of the cycle is the gametophyte generation.
She also gave birth to Ayacanora by Birdcatcher, and to Araucaria by Ambrose, both very valuable brood mares, Araucaria being the dam of Chamant by Mortemer, and of Rayon d'Or by Flageolet, son of Plutus by Touchstone.
Since the bacterial origin of foul brood has been established, the efforts of some bacteriologists have been employed in finding a simple remedy by means of which the disease may be checked in its earliest stages, and in this an appreciable amount of success has been attained.
Here and there a couple of bees, by force of habit and custom cleaning out the brood cells, with efforts beyond their strength laboriously drag away a dead bee or bumblebee without knowing why they do it.
Its three roots go down into the three great realms - (I) of death, where, in the well Hvergelmer, the dragon Nidhug (Niandggr) and his brood are ever gnawing it; (2) of the giants, where, in the fountain of Mimer, is the source of wisdom; (3) of the gods, Asgard, where, at the sacred fountain of Urd, is the divine tribunal, and the dwelling of the Fates.
Fear seemed to brood over the peoples of Western Europe.
A brood mare requires plenty of exercise at a slow pace and may work, except between shafts or on a road, till the day of foaling.
