Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
Poultry is the second most widely eaten type of meat in the world, accounting for about 30% of total meat production worldwide compared to pork at 38%. Sixteen billion birds are raised annually for consumption, more than half of these in industrialised, factory-like production units. [ 58 ]
Harry S. Lamon was the senior poultry expert of the Bureau of Animal Industry of the U.S. Department of Agriculture.From 1912, working at the Henry A. Wallace Beltsville Agricultural Research Center in Beltsville, Maryland, he crossed white Plymouth Rocks, silver-gray Dorkings and white Leghorns to produce a breed with good egg-laying capabilities which would – unlike most layer breeds ...

Members of this order are called carnivorans, or colloquially carnivores, though the term more properly refers to any meat-eating organisms, and some carnivoran species are omnivores or herbivores.
Of the approximately 174,250 lepidopteran species described until 2007, butterflies and skippers are estimated to comprise approximately 17,950, with moths making up the rest. [ 6 ] [ 7 ] The vast majority of Lepidoptera are to be found in the tropics, but substantial diversity exists on most continents.
[4]: 432 His aim was to produce a dual-purpose chicken that would be suitable for meat production and would also lay large white eggs. By cross-breeding of Barred Plymouth Rock and White Leghorn birds, an autosexing breed with barred gray adult plumage was produced. As in other autosexing breeds, the sex of chicks can be distinguished at about ...
The breed was developed at the Rutgers Breeding Farms in New Jersey, [1] with birds imported from Holland being crossed with White Leghorns, Rhode Island Reds, New Hampshires, and Lamonas, which created the White Hollands.
