The scientific name Phthonandria (Hemerophila) atrilineata Butler is Lepidoptera, Geometridae. Synonyms Menophra atrilineata (Butler) alias Sangzhi bridge insects, exfoliative insects. Distribution of Jiangsu, Anhui, Zhejiang, Shandong, Hebei, Liaoning, Jilin, Hunan, Hubei, Guangdong, Guangxi, Sichuan, Yunnan, Guizhou and other sang areas. The host mulberry tree. The characteristics of larvae in early spring feeding mulberry often empty the interior, leaving only the loquat leaves, spring larvae feeding on new shoots, after the larvae eat the leaves into a short cut, leaving only the veins of serious, resulting in weakening tree vigor, mulberry leaf significantly reduced production . It is the mulberry spring pest Living habits are three generations north of Shandong, three to four generations in Guizhou, and four generations in Anhui, Jiangsu, and Zhejiang. They use 3-4 larvae for wintering under dry gaps or branches of mulberry branches. The spring, winter and winter buds began to move in March and April, damaging the buds and young leaves. The larval activities of various generations are generally in the period of late May to early June, late July, late August and late September and early October. When the temperature of the fourth generation larvae falls below 16°C in the months from the end of October to the beginning of November, 3-4 larvae begin to overwinter. Adult phototaxis, hi eggs produced in the back of the branches on the back of the tender leaves, the general production of more than 600 tablets, up to 1177 tablets, egg period of 4-9 days. The newly hatched larvae walk on the dorsiflexion of the leaves and stand upright on leaves. A total of 5 instar larvae, matured in the vicinity of the main surface of the earth. Feast period 7-20 days. The occurrence of this insect is related to the temperature. High temperatures in winter, mulberry gardens, large number of bases, the spring occurs early; after May, more rain, little rainfall intensity, high temperatures, but also conducive to the occurrence of the worm. The main natural enemies are mulchers, mulchers, mulchers, mulchers, and black egg bees. Control methods (1) When collecting leaves, pay attention to killing larvae. (2) Bundles rice or wheat straw bundles on the shoots before wintering, trapping larvae into the grass to overwinter and concentrate killing in winter. (3) In the first half of the spring buds, the mulberry winter buds begin to turn green but they have not been dislocated or cut off or after the summer harvest. Spray 90% crystals of trichlorfon 1000 times or 80% dichlorvos 1200 times, 50%. Phoxim EC 1000-1500 times solution, 50% killer pine EC 1000 times solution, 25% imidophos EC 3000 times solution. (4) Autumn silkworms are sprayed with 2.5% kungfusin or 20% fenvalerate or 2.5% chlorpyrifos and other pyrethroid insecticides 4000-5000 times, 5% fipronil suspended Agent 1500 times, 10% imidacloprid wettable powder 2500 times. (5) Biological control Artificial release of M. ulmoides, parasitism rate is 70% to 80%. The mycelium is multicellular, has transverse septum, and is elongated by the growth of the apex, white, slender, woolly, gradually becoming filamentous. Mycelia are conjugated with each other to form a dense population, called mycelia. After mycelium saprophytic, the brown culture medium turned light brown. The fruiting body of a mushroom is like an open umbrella when it matures. It is composed of bacteria cover, stalk, fungus fold, fungus ring, pseudomycorrhiza and so on. Mushrooms are widely distributed throughout the earth and are most abundant in forest deciduous areas.
