Lupinus albus beans, cooked and pickled in brine.. The beginning of lupin cultivation in the Old World is sometimes associated with Ancient Egypt. [4] It is more likely, however, that white lupin was originally introduced into cultivation in ancient Greece, where its greatest biodiversity was concentrated and where wild-growing forms have been preserved until today (ssp. graecus). [5]
Lupinus albifrons, silver lupine, white-leaf bush lupine, or evergreen lupine, is a species of lupine (lupin). It is native to California and Oregon , where it grows along the coast and in dry and open meadows, prairies and forest clearings.
Trialeurodes vaporariorum, commonly known as the glasshouse whitefly or greenhouse whitefly, is an insect that inhabits the world's temperate regions. Like various other whiteflies, it is a primary insect pest of many fruit, vegetable and ornamental crops.
The species are mostly herbaceous perennial plants 0.3–1.5 metres (1–5 feet) tall, but some are annual plants and a few are shrubs up to 3 m (10 ft) tall. An exception is the chamis de monte (Lupinus jaimehintonianus) of Oaxaca in Mexico, which is a tree up to 8 m (26 ft) tall.
The insects and their wings are variously marked or mottled according to species, and many species are covered with fine wax powder, giving most species a floury, dusted appearance, hence names such as Aleyrodidae, Aleurodidae and Aleuroduplidens; the root refers to the Ancient Greek: αλευρώδης (aleurodes) meaning "floury".

The parasitoid is sold commercially for biological control of whitefly, an insect pest of tomato and other greenhouse crops. Encarsia formosa has been used as a natural pesticide to control whitefly populations in greenhouses since the 1920s. Use of the insect fell out of fashion due to the increased prevalence of chemical pesticides and was ...
Tailcup lupine, Lupinus argenteus in Nevada, White Mountains, Middle Creek, Fishlake Valley drainage, elevation 2539 m. The flowers of Lupinus caudatus are 8–12 millimeters long with a conspicuous blunt spur that is 0.4–1 millimeter long. [1] [2] Most often the flowers are blue-purple in color, but occasionally they will be white. [3]
Planting different host crops away from each other will decrease the number of plants the flies will be able to infect. Thus, the best control is to maximize the distance and time interval between host crops. [23] Good sanitation in winter and spring crops is also required for the maintenance and control of the fly population. [23]
