A genus of moths.

T. luscana generates a red grub, and T. cynosbana a black-spotted green grub, both very destructive of blossom buds.

T. Vitisana

Vine Tortrix. Found on the vine in April and May; head yellow; upper wings marbled with rusty and gray colours. Caterpillars appear as the blossom buds open, which they unite with white threads.

T. Nigricana

Red Plum Grub Tor-trix. Moth black, appearing in June. Eggs deposited on the plum; grub, small red, pierces the fruit, and is found near the stone. Mr. Curtis observes, that - "If the plums that have fallen off be examined, a small red caterpillar will be found within it; the caterpillar being generally full grown when the plum falls off, soon creeps out, and penetrates the loose bark, forming a case in which it remains during the winter. Early in the spring it changes into a light brown pupa, and the moth emerges about June. The moth is not so large as a house-fly; its wings are almost black, and when the sun is shining on them, they have a remarkably metallic lustre; on the outer edge of the fore wings there is an appearance of fine silver dust. Among the remedies proposed to lessen the ravages of this insect, it is recommended to shake the trees, and remove all the fruit that falls off; and another good method is to scrape the rough pieces of bark of the stem, under which the cocoons are concealed; this must be done late in the autumn, or early in the spring." - Gard. Chron.

T. Bergmanniana

Rose Tortrix. Differs little to a common observer from the preceding. "Where bushes are much infested with the larva; of these insects, it is much better to cut them down and burn the shoots; this and hand-picking are the only remedies we are acquainted with. Care must be taken not to disturb the maggots when collecting them, for they will let themselves down by threads, and thus escape." - Gard. Chron.

T. Ocellana

This is the parent of the red bud caterpillar, which destroys the buds of the apple and pear. Upper wings gray, with a white transverse band.

T. Woeberiana

Plum tree Tortrix. Its larva feeds on the inner bark of the plum, apricot, almond, and peach. The grubs pierce holes through the bark, which may be detected by small heaps of red powder upon it. Moth brown; grub greenish, with a red head.

T. Pomonana

Codling Moth. Its reddish-white grub is common in apples and pears. Moth light gray, streaked with dark gray. Seen of an evening during May, and the grubs appear soon after. All fallen apples should be destroyed, because they usually contain this or other grubs, which will otherwise produce moths, and multiply the evil.

"T. turionana, T. hyrcyniana, T. resinella, and T. buoliana, all infest pine trees, injuring them by depositing their eggs in the buds, which are subsequently preyed upon by their caterpillars." - Kollar. - Gard. Chron.
