Economic Significance
The Lime Butterfly is an economic pest on many cultivated citrus species in India, Pakistan, Iraq and the Middle East. Due to its history of successful dispersal and range extension, the Lime Butterfly is likely to spread from its original point of introduction in Hispaniola in the Caribbean to neighbouring Florida, Central America and South America. Due to its capability for rapid population growth under favourable circumstances and its having been recorded to have five generations in a year in temperate regions of China, it is considered a serious potential threat. The caterpillars can completely defoliate young citrus trees (below 2 feet) and devastate citrus nurseries. In mature trees, caterpillars may prefer young leaves and leaf flush.
Hand-picking of caterpillars and spraying with Endosulfan 35 EC (2 ml/10 litres of water) were the recommended means of pest control by Indian government agencies and agricultural colleges, however, Endosulfan has since been banned by the Supreme Court of India.

Famous quotes containing the words economic and/or significance:
“The first panacea for a mismanaged nation is inflation of the currency; the second is war. Both bring a temporary prosperity; both bring a permanent ruin. But both are the refuge of political and economic opportunists.”
—Ernest Hemingway (1899–1961)
“Of what significance the light of day, if it is not the reflection of an inward dawn?—to what purpose is the veil of night withdrawn, if the morning reveals nothing to the soul? It is merely garish and glaring.”
—Henry David Thoreau (1817–1862)
