The Tortricidae or tortrix moths are a family of the Lepidoptera. It is a large family with over 6,000 species described. Many of these are economically important pests. Olethreutidae is a junior synonym. The typical resting porture is with the wings folded back producing a rather rounded profile.

The Tortricids include many economically important pests, including :-
- Summer fruit tortrix moth (Adoxophyes orana)
- Fruit tree tortrix moth (Archips podana)
- Rose leaf roller (Archips rosana)
- Argyrotaenia ljungiana, a pest on vines, maize and fruit trees

- Codling moth (Cydia pomonella)
- Plum fruit moth (Cydia funebrana)
- Pea moth (Cydia nigricana)
- Chestnut and acorn moth (Cydia splendana)
- Grape berry moth (Endopiza viteana)
- Light brown apple moth (Epiphyas postvittana)
- Oriental fruit moth (Grapholita molesta)
- Cherry fruitworm (Grapholita packardi)
- Vine moth (Lobesia botrana)
- Barred fruit tree tortrix moth (Pandemis cerasana)
- Long-palped tortrix (Vine leaf roller) (Sparganothis pilleriana)

[edit] A typical Tortricid - the Codling moth
Tortricidae is considered to be the single most important family of insects that feed on apple, both economically and in diversity of feeding found on fruit, buds, leaves and shoots. In New York state, no less than 17 species of Tortricidae have gained pest status in regards to apple production.
The Codling moth Cydia pomonella is the species which causes worm-holes in apples. It has been accidentally spread from its original range in Europe and is now found in North and South America, South Africa, Australia and New Zealand wherever apples are grown. Control has required the use of the harshest available insecticides - historically lead arsenate and DDT were used. These chemicals brought considerable environmental dangers, and in any case the insect gradually developed resistance to them. Currently organophosphate sprays are favoured, timed carefully to catch the hatching larvae before they can bore into the fruit.
