  • Title
    Interactions between insect pollinators and the ornamental tree, Tecoma stans (L.)
    Journal Article
    Tecoma stans (Bignoniaceae) is a native of Central America but occurs throughout tropical latitudes due to cultivation as an ornamental; in India it is also normally cultivated as an ornamental tree. The plant has two anthesis schedules in a day - one during 0500-0800hrs and another during 1500-1700hrs. Different species of bees and wasps collect pollen and nectar from the flowers during daylight hours, while hawk moths collect nectar during the 0530-0700hrs and 1630-1830hrs periods. The flowers are an important source of pollen and/or nectar for these insects, and all facilitate pollination. The nectar contains three common sugars: hexoses, glucose and fructose, and it is also a source of three essential amino acids: lysine, histidine and threonine, and eight non-essential amino acids: glycine, serine, proline, arginine, glutamic acid, cystine, cysteine and alanine. With these floral rewards, T. stans sustains pollinator populations in areas where it is cultivated.
