Pieris Rapae
''Pieris rapae'' is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America as the cabbage white or cabbage butterfly, on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from '' P. brassicae'' by its larger size and the black band at the tip of its forewings. The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and broccoli. ''Pieris rapae'' is widespread in Europe and Asia; it is believed to have originated in the Eastern Mediterranean region of Europe, and to have spread across Eurasia thanks to the diversification of brassicaceous crops and the development of human trade routes. Over the past two centuries, it spread to North Africa, North America, N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Large White
''Pieris brassicae'', the large white, also called cabbage butterfly, cabbage white, cabbage moth (erroneously), or in India the large cabbage white, is a butterfly in the family Pieridae. It is a close relative of the small white, ''Pieris rapae''. The large white is common throughout Europe, North Africa and Asia. Distribution The large white is common throughout Europe, north Africa, and Asia to the Himalayas often in agricultural areas, meadows and parkland. It has managed to establish a population in South Africa and in 1995 it was predicted to spread to Australia and New Zealand. The large white is a strong flier and the British population is reinforced in most years by migrations from the continent. Scattered reports of the large white from the north-eastern United States (New York, Rhode Island and Maine) over the past century are of a dubious nature and indicate either accidental transport or intentional release. Such introductions threaten to establish this agric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations.

Glucosinolate
Glucosinolates are natural components of many pungent plants such as mustard, cabbage, and horseradish. The pungency of those plants is due to mustard oils produced from glucosinolates when the plant material is chewed, cut, or otherwise damaged. These natural chemicals most likely contribute to plant defence against pests and diseases, and impart a characteristic bitter flavor property to cruciferous vegetables. Plants with glucosinolates Glucosinolates occur as secondary metabolites of almost all plants of the order Brassicales. Ordered in the Brassicales are for example the economically important family Brassicaceae as well as Capparaceae and Caricaceae. Outside of the Brassicales, the genera ''Drypetes'' and ''Putranjiva'' in the family Putranjivaceae, are the only other known occurrence of glucosinolates. Glucosinolates occur in various edible plants such as cabbage (white cabbage, Chinese cabbage, broccoli), Brussels sprouts, watercress, horseradish, capers, and radishes wh ...

Sisymbrium Officinale
''Sisymbrium officinale'', the hedge mustard, (formerly ''Erysimum officinale'') is a plant in the family Brassicaceae. Description It is distinct from the mustard plants which belong to the genus ''Brassica''. ''S. officinale'' is similar to other ''Sisymbrium'', but differs in its tall, erect stems with tiny flowers and fruits that are compacted parallel to the stem instead of hanging free. ''S.officinale'' grows to 80 cm high. The lower leaves are broad with two or three lateral lobes. The flowers are about 4 mm across and yellow. Fruits are long and without hairs when young but show hairs when mature and reach 18 mm long on racemes pressed close to the stems. Hedge-mustard is food for the caterpillars of some Lepidoptera, such as the small white (''Pieris rapae''). Distribution Found in Ireland, Wales and England and also in the highlands of Scotland. It is found on roadsides, wasteland and as a weed of arable land. A native of Europe and North Africa, it i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charlock
''Sinapis arvensis'', the charlock mustard, field mustard, wild mustard, or charlock, is an annual or winter annual plant of the genus ''Sinapis'' in the family Brassicaceae. It is found in the fields of North Africa, Asia and Europe. ''Pieris rapae'', the small white butterfly, and ''Pieris napi'', the green veined white butterfly are significant consumers of charlock during their larval stages. Description ''Sinapis arvensis'' reaches on average of height, but under optimal conditions can exceed one metre. The stems are erect, branched and striated, with coarse spreading hairs especially near the base. The leaves are petiolate (stalked) with a length of . The basal leaves are oblong, oval, lanceolate, lyrate, pinnatifid to dentate, long, wide. The cauline leaves are much reduced and are short petiolate to sessile but not auriculate-clasping.

Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Life Zone
The life zone concept was developed by C. Hart Merriam in 1889 as a means of describing areas with similar plant and animal communities. Merriam observed that the changes in these communities with an increase in latitude at a constant elevation are similar to the changes seen with an increase in elevation at a constant latitude. The life zones Merriam identified are most applicable to western North America, being developed on the San Francisco Peaks, Arizona and Cascade Range of the northwestern USA. He tried to develop a system that is applicable across the North American continent, but that system is rarely referred to. The life zones that Merriam identified, along with characteristic plants, are as follows: * Lower Sonoran (low, hot desert): creosote bush, Joshua tree * Upper Sonoran (desert steppe or chaparral): sagebrush, scrub oak, Colorado pinyon, Utah juniper * Transition (open woodlands): ponderosa pine * Canadian (fir forest): Rocky Mountain Douglas fir, quaking aspe ...
