根据1998~2010年12a鼠情监测,明确了小家鼠在天门农区的消长繁殖规律。12a间出现了3次波动,1999年至2001年处于优势地位,2002年至2005年略低于黄胸鼠。从2006年至今又上升为优势位置。全年以6、9、12月为上夹率高的三个峰期,1、7月上夹率最低。雌雄性比例为1:0.72,胎平仔数4.64只,子宫斑(胎迹)8.96个。最适时的灭鼠时机为4~5月和10~11月。
According to the 1998 ~ 2010 12a rat monitoring, the growth and development of Mus musculus in the Tianmen farming area were clarified. There were three fluctuations between 12a and from 1999 to 2001, which was slightly lower than that of Rattus flavipectus from 2002 to 2005. From 2006 up to now has risen to the dominant position. In June, September and December, the three peak periods with high clip rate were the highest. The clip rate was the lowest in January and July. The ratio of male to female was 1: 0.72, the number of litter size was 4.64, and the number of uterine plaques was 8.96. The most appropriate time for rodent control is April to May and October to November.
