摘要
得出了烟草甲卵、幼虫、蛹、成虫静止期的发育起点温度及有效积温，分别为１４．４５℃和１０７．８日度，１７．６６℃和２７２．１日度，１３．２８℃和７６．８日度，１４．５８℃和７１．７日度；明确了烟草甲幼虫生存的最适、适宜和不适宜的温、湿度组合区及幼虫１００％死亡所需天数（ｙ）与低温值（ｘ）的相关式。长沙地区烟草甲每年可发生完整的３代，每年５～９月为盛发期。就除氧、降温、去湿、磷化铝薰蒸、黑光灯诱杀等防治措施进行了调查研究。
The thresold
temperature of development and effective constant of egg,larve,pupa and adult of Lasioderma
serricorne(Fabricius)were as follow 14.45℃,107.8 day de-gree;17.66 ℃,272.1 day
degree;13.28℃, 76. 8 day degree;14. 58℃,71. 7 day degree re-spectively. The optimum,fit and
unfit range of temperature and humidity for the survival ofthe larva,and the regressive formula
between the essential days of making the larva all dead(y)and low temperature(x)were
obtained.Lasioderma serricorne(Fabricius )can occur 3generations completely each year,and
the periods,is from May to September, for its opti-mum occurrence,according to the systematic
recorders of temperature in the tobacco store-room of Changsha cigarette factory.The peak
period for emergence of its overwintering gen-eration was 16 May in 1993.Some control
measures,as lower temperature,getting rid of oxy-gen and water vapor,fumigating with
Aluminium Phosphide,and trapping in dark moth killing lamp,were studied.
