The disease is mainly controlled by the elimination of the western flower thrip vector and by destroying any infected plant material.

INSV has a wide host range and can be found in over 300 plant species including weeds, fruits, vegetables and ornamental crops.

[10] Temperature and host both play an important factor when discussing the symptoms which an INSV infected plant will display.

When New Guinea Impatiens are cultivated in an environment varying between 75 and 80 degrees Fahrenheit the host plant will be highly symptomatic.

[11] When lettuce is infected with INSV, it shows a number of symptoms, such as yellowing leaves, dead spots, and stunted growth.

They are especially prevalent in warmer areas of the mountain west and pose the most notable threat to the popular apple cultivars of the region such as "Granny Smith" and "Ginger Golds."

Apple cultivars will show great signs of cosmetic damage including large, dark halos with a central russet.

Despite the cosmetic damage suffered by these light skinned apple cultivars they are seemingly unaffected by most thrip vectored viruses.

Infested apples of the mountain west simply provide a natural setting for Western Flower Thrips to thrive and reproduce.

Due to the large natural environment and hundreds of hosts Vector transmission allows the virus a range limited only by the reach of the insect.

(3)[13] Greenhouses provide ideal environments for Western Flower Thrips and preventative measures must be taken in order to insure healthy plants.

[14] Although Wester Flower Thrips were at one time only a pest across the western United States and Canada, their spread has now reached worldwide.

By raising Enzyme-linked immunosorbent assays against the nucleoproteins of symptomatic species, eight isolates have been identified in Italian vegetable and ornamental crops alone.

[17] By providing favorable year round conditions, greenhouses allow INSV carrying Western Flower Thrips a permanent residence unless eradicated.

INSV can attack 648 different species, being the number one disease in gloxinia and impatiens, and has numerous symptoms often making diagnosis more difficult.
