Scarab is one of main pests with common orchard, happen serious when, imago can be dispose of flower, tender leaf, its are larval (grub) the root ministry that harms crop, it is the harm in subterranean pest is the greatest kind group, big to the harm of the fruiter, affect orchard economic benefits badly. Scarab is the imago of subterranean pest grub, it is pest of a kind of polyphagia. Often be with larva or imago in earth live through the winter. Chafer of the chafer of wool having Ping with harm fruiter common chafer, verdigris chafer, black fine hair, Bai Xing spends scarab He Xiaoqing to spend scarab to wait for 5 kinds. Sort reachs a harm: Ping wool chafer, small green beautiful chafer and chafer of black fine hair all bite the bud that feeds the fruiter such as apple, pear, peach, apricot, bud, leaf and tender leaf with imago. Happen to will be spent badly constantly implement or tender leaf dispose of, affect the crop of the fruiter and tree situation. Verdigris chafer is bitten with imago feed fruiter lamina, serious when but blade dispose of, only remnant nervation and Xie Bing, be opposite especially young age the harm that the fruiter causes is greater. White star beautiful chafer is gnawed with imago eat the flesh of fruit, form bug spot, decay namely later, fall off. Produce the law: The first: Scarab is mostly in soil live through the winter, come up out of land period in March the last ten-day of a month comes in April the first ten days of a month, main harm is spent implement, germinal with tender leaf. The 2nd: Come by April at the beginning of May, harm of the 2nd chafer can be raided, it is black tortoise and verdigris mostly beautiful chelonian child, basically feed young fruit in order to endanger blade and eat by moth to give priority to, garden of apple, walnut wants to pay close attention to highly. triple wave: Wheat harvest around, endanger fruiter lamina. The 4th: The summer, endanger mature fructification. The prevention and cure of scarab: 1 agricultural prevention and cure: The union at the beginning of Qiu Modong applies base manure to undertake breaking up greatly to the orchard, in order to eliminate a large number of larva (grub) ; Sufficient become thoroughly decomposed wants when the orchard applies farmhouse fertilizer, with reducing grub source effectively; Be inside the orchard or the crop such as legume, earthnut, potato, sweet potato should be not cultivated to often keep clear of as far as possible all round the orchard all round the orchard fireweed, destroy the surroundings that imago lays eggs. 2 catch artificially kill | | | Use the play dead sex of scarab, dusk preexistence cultivates dish of lower berth a plastic cloth, again jolty branch, shake falls scarab destroys kill. Or pour scarab kill in boiled water, fish out pound sends ferment smell below sunshine, add water filters gush crown of a tree, 10 ～ do not have scarab 15 days. Candy of 3 trap and kill 1, vinegar 3, wine 0.5, water 10, after add is good, in holding potted bottle, hang to the tree, receive bug to buy juice everyday, 15 days change sweet-and-sour fluid. What bottle needs to be hanged in periphery of crown of a tree to be in without keep out is medium on upside branch, be discovered so easily by remote insect. Note wind direction, need to be hanged in the position of uptake. Use imago of phototaxis trap and kill, all sorts of scarab imago phototaxis are very strong, usable solar energy kills bug lamp or Zhen Pin type reduces bug lamp lure to destruction.
