Almond bee: The larvae overwinter in the apricot nucleus or in the apricot nucleus on the shoots. The female adults spawn between the nucleus and the almonds. The oviposition holes on the fruit surface are not obvious. They are slightly grayish green, sag, and sometimes spawn. The hole has apricot outflow and the egg period is about 10 days. The hatched larvae eat almonds in the nucleus and cause a large number of fruit drops. About mature in early June, that is, wintering in the apricot nucleus. Control methods: 1 Pick and drop the fruit, remove the fruit from the tree, and concentrate deeply or burn it to destroy the overwintering larvae. 2 Deep plowing and deep plowing (15 cm in depth) The insects should be turned into the soil so that the adults cannot feather out of the soil (the larvae can still emerge normally in 3.5 cm depth of soil). 3 In the processing of almonds, the worm nucleus selected by the water was burned. In early April, the adult eclosion was sprayed with 90% crystals of trichlorfon 1000 times. Peach fruit borer: damage the fruit with larvae, larvae after hatching, bite the peel into the fruit and penetrate into the fruit in a vertical and horizontal direction, feeding directly to the fruit heart, the insect fruit accumulated within the feces, bitter and inedible. Control methods: 1 before the winter larvae unearthed, in the tree tray sprinkled with 50% killing pine oil 2000 times, then deep down. 2 Remove the disease and handle it at any time. 3 When the larvae are incubating, the leaves are sprayed with 2000 times 50% methyl 1605 EC or 1500-2500 times methional. 4 Adults are tempted to kill adult insects with black-spotted moths or black light lamps. Atelier caterpillars: mainly take larvae to shoot buds and new leaves. When they occur in large numbers, they can eat up all the leaves of the tree, affect flower bud differentiation and fruit set in the following year. Prevention methods: 1 combination of winter shear, cut off the egg block burned. 2 When the larvae have just hatched, the leaves of their gregarious groups are gently removed and eliminated. 3 Foliar spraying of 50% dichlorvos 1000 times or 40% dimethoate 1000 times to kill the leaf-feeding larvae. Folium Isatidis: Damage to the sap of adults and nymphs. When spawning at the end of the fall, the stems of the fruit tree branches are cut with an ovipositor, causing the affected branches to be black and blue, causing the trees to lose water. Control methods: 1 For fruit trees with large amount of overwintering eggs, especially saplings, use wooden sticks to squeeze eggs and eliminate overwintering eggs. 2 Pay attention to clearing field weeds and reduce intermediate hosts. 3 When adults and nymphs occur, the leaves are sprayed with 50% dichlorvos 2000 times or 40% fenvalerate 2000 times. Flat moth: damage caused by larvae feeding the leaves. In young age, the leaves are only eaten on the back of the leaves, leaving the veins behind them. When they grow up, they eat the whole leaf. Control methods: 1 Exterminate overwintering insects in tree trays, especially under the main root neck. 2 When the larva occurs, the leaves are sprayed with 50% dichlorvos 800-1000 times fluid or 40% fenvalerate 2000 times fluid. Red-necked longhorned pheasant: The larvae feed on the surface of the branches and directly affect the growth. In severe cases, the entire trunk of trees will die. Control methods: 1 before the emergence of adults, the trunk or large branches painted white coating agent (calcare: sulfur powder: salt: water is 10:1:0.2:40) to prevent adult eggs. During adulthood, adults are killed manually. During larvae damage, the larvae were killed by wire. Apricot balls are firm: they are sucked on the stems by female adults or nymphs and sucked on sap. Causes tree weakness or dead branches. Control methods: 1 In adult pods have been formed, before the eggs are hatched, the females are scraped. 2 The nymphs were sprayed with 0.2 bumeide lime sulfur or 50% dichlorvos 1500 times during the incubation period.
Huangshan Gongju, also known as Hui Ju, Gongju. Because in ancient times as a tribute to the emperor, hence the name "tribute chrysanthemum."
