The scientific name Homona magnanima Diakonoff is Lepidoptera, Tortricidae. Alias ​​tea leaf roller moth, brown leaf roller moth. It is a recent species of the citrus leaf roller moth. Distribution of Jiangsu, Anhui, Hubei, Sichuan, Guangdong, Guangxi, Yunnan, Hunan, Jiangxi and other provinces.
Host tea, wolfberry, wolfberry, citrus, persimmon, pear, peach and so on.
The characteristics of the newly hatched larvae were contaminated with tips of the leaves, which occupies the upper epidermis and mesophyll, and left the lower epidermis, resulting in the yellow leaves and thin film spots on the leaves. The leaves of the older larvae became nicks or holes.
Morphological characteristics Adult females are 10mm long, 23-30mm wingspan and light brown body. Antenna filamentous. The forewings are nearly rectangular in shape, light brown in color and dark brown in wing tips. There are many dark brown fine lines on the wing surface. Some individuals have a dark brown, slanted transverse belt with a thick inner fin scale and a fin outside. The hind wing meat is yellow, scalloped, and its leading edge and outer edge are darker or mostly dark brown. Male adults are 8mm long, 19-23mm wingspan, yellow-brown foregrets, dark brown at the center of the base and wings, a black-brown round spot in the center of the leading edge, and the base of the leading edge has a thick-brown and oval-shaped protrusion, partially backwards. Reflex, cover at the shoulder corner. The hind wings are grayish brown. Egg length 0.8-0.85mm, flat oval, light yellow. The last instar larvae are 18-26mm in length, yellowish-green in color, yellow-brown in the head, nearly semicircular in the thoracodorsal plate, brown, dark brown on the posterior border and both sides, and 2 dark brown, oval-shaped, small keratin dots on each side. The chest is dark. The dragonfly is 11-13mm long, dark brown, with long thorns, and 8 hooks.
Living habits Zhejiang and Anhui were born 4 generations, and Taiwan 6 generations. They crouched on the larvae to winter. In early April of the following year, phlegm began to occur. In late April, adults emerged spawning. The first generation of the egg is from late April to early May. The larval period is from mid-May to late May, from late May to early June, and the adult period is from June. The second-generation egg period is in June, the larval period is June-July-July, and the mid-July-mid-July period is the flood season. The adult period is in mid-July. Three generations took place in the middle of July and September, and the fourth generation took place in April of the last year of September. The average temperature was 14°C, the egg period was 17.5 days, and the larval period was 62.5. Days; average temperature 16 °C, 19-day flood season, adult life of 3 - 18 days; average temperature 28 °C, complete a generation of 38-45 days. Adults are more likely to emerge at 6 o'clock in the morning and inhabit the leaves of the tea bushes during the day. They are most active after sunset and 1–2 hours before sunrise. They have phototaxis and chemotaxis. After the emergence of adult eclosion, the animals can be copulated on the same day, and spawning begins after 3-4 hours. Eggs grow on the front of the old leaf, producing 330 eggs per female. The newly hatched larvae are dispersed by crawling or drooping. In case of young shoots, the tips of the spit-spun squiggly leaves tip into the larvae to feed. A total of 6 instar larvae, old mature, more than the original, insects reconstruct two old leaves, phlegm in which. Natural enemies include Trichogramma, Bumblebee, Bumblebee, and Drosophila.
