1, do well actively before sericiculture clean disinfection. Spring silkworm, early of autumn silkworm raised different level to increase silkworm room, silkworm to provide the fresh bacteria inside, autumn period high temperature is much wetter the breed that is a bacteria again offerred advantage, the force causing disease of bacterium of cause of disease is very powerful, the disinfection before sericiculture is crucial. Before raising late autumn silkworm, with 1 ％ effective chloric pH indicator " disinfection is clean " or " bleaching powder " disappear venom undertakes sparge or macerate is disinfected, in order to maintain half hours wet to spend.
2, ill measure is defended during strengthening sericiculture. With " destroy deadlocked is clever " or " prevent disease " (1 ～ 3 age prevent disease with small silkworm, 4 ～ 5 age prevent disease with big silkworm) , often be opposite silkworm body silkworm undertake alexipharmic, with silkworm body silkworm appear shape of a Bao Shuang is degree. And still be added had fed " fluorine Pai is acerbity " or " chloromycetin " wait for the medicaments that prevent disease.
3, be on guard strictly to be affected with across of mulberry field pest. Show the pest inside level mulberry field more, after bug dung pollutes Sang Xie, follow collect a leaf to take silkworm room together, produce alternate infection very easily with late autumn silkworm. Accordingly, small silkworm cannot select bug mouth part of a historical period with the leaf or bug dung pollutes a leaf, in case get ill by the mouth. In the meantime, silkworm of die in one's bed, puny silkworm cannot drop about chaos is cast or feed gallinaceous duck, should put fill the concentration inside the special containers esp. for use in the house that has bleaching powder or lime to be buried greatly, cause pathogeny to diffuse to be infected again in case.
4, alarm prevent drug of late autumn silkworm raiser toxic. Because farm orders bug number this year more, and mulberry field treats bug more frequent also, late autumn silkworm period should take strict precautions against silkworm toxic. In raising a process, need not be polluted to cross Sang Xie by pesticide as far as possible, once discover toxic phenomenon, should timely take remedial action, add feed atropine to have relieve internal heat or fever, change instantly Tian Kuai selects a part of a historical period. To the rice field the mulberry field all round must do good foretaste work, avoid to create large area because of selecting a part of a historical period blindly toxic.
5, the adjustment that catchs temperature of good raise Yo. Late autumn period, climate change is sharp, day and night difference in temperature is big, cause high low temperature easily to pound, weaken the resistance of silkworm, reduce the constitution of silkworm. Accordingly, when indoor by day air temperature exceeds 28 to spend, should have done drop in temperature the job; In the evening temperature under 24 degrees when, want to do work of good heat preservation; Conditional place should undertake " small silkworm in all Yo " .
