A little bat moth
Distribution and hazards
The larvae moth into the larval tree from the base of the trunk 1 meter from the ground, spit silk knot net, moth the xylem, the outside of the worm mouth is filled with wood chips, stuck to the silk net, until the silk mesh is full of wood chips and connected into a package to cover the hole, first feed around the trunk for a week, and then moth into the marrow heart and feed downwards, resulting in the upper part of the tree wilting or breaking, easy to wind fold. Moths sometimes go deep into the underground roots. The old mature larvae make a silk cap to block the inner mouth of the worm passage to pupate.
Morphological characteristics
Adults are 25–47 mm long and have a wingspan of 50–120 mm. Female moths are larger. The body is dark brown and densely covered with pinkish green and pinkish brown fluff. The head is small, with long hairs on the top of the head, the mouthparts are degenerate, the antennae are short, there is a nearly triangular black-brown stripe in the middle of the forewing, and there are silver-white spots, and the middle of the near wing is a silvery-white short oblique stripe, and the end is "!" the form separates out a little. The outer margin line has a dark brown broad band line, and the sub-outer edge line is a wide dark brown short oblique ripple. The forefoot is flattened, broad, hairy, and extends forward when stationary, very bat-like. The male moth has long orange-red brushed hairs on the back of the leg segments of the hind feet.
The eggs are 0.5–0.7 mm long, oval in shape, white at first birth and black later.
Larvae Mature larvae are about 75 mm long , yellowish-white , oblong-cylindrical , with a brown head and thorax dorsal plate , a dark brown mast in the center of each segment of the body , oval in shape , and four smaller light brown masts on each side.
The pupa is 40–50 mm long, yellowish brown, cylindrical, with a dark brown head and pointed teeth on the top of the head. The abdomen is tubular in shape with transverse dental processes on the back.
Regularity of occurrence
The worm occurs in 2 generations, overwintering in tunnels at the base of tree trunks with eggs on the ground or as larvae. Hatching in mid-April of the following year, the young larvae feed on humus, and after 2 to 3 years of age, they turn to the main trunk of fir trees, paulownia and other young trees to eat moths, and have been endangered until the winter. In mid-May of the third year, the mature larvae pupate, and in early June, the adults begin to feather, mate and lay eggs. Adults feather in the evening, lie still on tree trunks, undergrowth or weeds during the day, and the eggs are scattered on the ground or ground cover. Most fly at 19-20 o'clock in the evening, and the adult lifespan is 6-8 days. When the larvae moth into the larval tree, they mostly burrow from the base of the trunk about 1 meter above the ground, and the large trees mostly moth from the old worm hole or crack. Feed around the trunk for a week, then moth into the heart of the pulp and feed downwards, the moth into the tunnel downwards vertically, about 20 cm deep, sometimes deep into the underground roots. The inner wall of the worm passage is smooth, and feces and debris are all pushed into the cyst of the borer orifice, which is particularly large before pupalization. The mature larvae make a silk cap to block the inner mouth of the worm's passage, ready to pupate. There are many types of natural enemies, such as parasitic larvae of white zombie fungus, pupae, silkworm-bellied parasitic larvae, and bee parasitic larvae.
Prevention and control methods
(1) Protection and utilization of natural enemies.
(2) Select more insect-resistant varieties, strengthen cultivation management, enhance tree potential, and improve resistance. Create mixed forests to cut down dead trees with insects in time to reduce the spread of insect pests.
(3) When insect bags are found at the base of the trunk in the woodland, the insect bags are first peeled off, and then 30% cypermethrin wettable capsules or 80% dichlorvos 500 times liquid are injected into the worm tract with a syringe to poison the larvae.
(4) You can also use a soft strip made of bamboo to insert it directly into the moth to kill the larvae, and then block the hole with mud, which has a good effect.

That year today
On July 6, 2008, China's "Fujian Tulou" was officially inscribed on the World Heritage List.
Fujian Tulou, because most of them were built by Fujian Hakka, is also known as "Hakka Tulou". Tulou originated in the Song and Yuan dynasties and matured in the late Ming, Qing and Republic of China periods. With earth, wood, stone and bamboo as the main building materials, the use of unburned soil and a certain proportion of sand clay and clay sand mixed, rammed with sandwich panels to form a two-storey house.
Fujian Tulou includes Gaobei Tulou Group, Hongkeng Tulou Group, Chuxi Tulou Group, Yanxiang Lou and Zhenfu Lou in Yongding District, Fujian Province, Tianluokeng Tulou Group, Hekeng Tulou Group, Yunshui Ballad and Guilou and Huaiyuan Lou in Nanjing County, and Dadi Tulou Group in Hua'an County. Among them, The Second Yilou is located in Dadi Village, Xiandu Town, Hua'an County, which is an outstanding representative of the ancient residences of Yuanshilou in China, known as the "King of Tulou" and "the treasure of the country", it is famous for its grand scale, scientific design, reasonable layout and well-preserved, and is a national key cultural relics protection unit.
Fujian Tulou, as a form of architecture that the Hakka people in Fujian are proud of, is a treasure in the Fujian people's houses. At the same time, it also incorporates humanistic factors, which can be called the epitome of the combination of "heaven, earth and people". Dozens of households and hundreds of people live on the first floor, reflecting the family tradition of Hakka living together and living in harmony. Therefore, a history of Tulou is a history of rural families. The descendants of Tulou often do not need a family tree to talk about the origin of the family.
