Rhyacionia adana
Encyclopedia
The Adana Tip Moth is a moth
of the Tortricidae
family. It is found in north-eastern North America
, including Massachusetts
, Pennsylvania
, Virginia
, Michigan
, Wisconsin
and Ontario
.
The wingspan
is about 17 mm. There is one generation per year.
The larvae feed on various pine
species. The larvae mine the current year's shoots of red, jack and Scots pine seedlings and saplings (it attacks the lower halves of trees up to 25 feet tall). Serious damage has been recorded in red and Scots pine plantations in Massachusetts, Pennsylvania, Virginia, Michigan, Wisconsin, and Ontario.
The female lays her eggs between needles just above the sheath of the needle fascicle. Newly hatched larvae spin silken cases between two old needles just above the needle sheath. They then enter the needles and mine toward the tip. After new needle growth has started, larvae enter and mine developing shoots. Several larvae may inhabit a single shoot, moving toward the buds and causing shoot death. In mid June to late July, mature larvae move down the main stem of the tree and pupate in cocoons cemented to the stem just below the soil surface. Shoot death becomes apparent after the insect has pupated.
