【摘要】：目的探討腐食酪螨自然種群季節(jié)性消長動態(tài)及其在蕪湖市倉儲面粉中的空間分布型,為腐食酪螨的防制提供理論依據(jù)。方法自2013-1-2013-12,選擇蕪湖市區(qū)5個采樣點,每月進行定點采樣,鑒定及計數(shù)其中的腐食酪螨。運用擴散型指標(biāo)、Iwao m*--x回歸方程及Taylor lg S2-lg-x回歸分析研究腐食酪螨種群在倉庫面粉中的空間分布特征。結(jié)果蕪湖市區(qū)倉儲面粉中的腐食酪螨高峰期在7月和9月。擴散型指標(biāo)I0,CA0,m*/-x1;Iwao的線性回歸方程為m*=3.740 3+1.017 5-x(r=0.995 8),Taylor線性回歸方程為lg S2=0.500 4+1.134 9 lg-x(r=0.832 8),表明腐食酪螨在倉儲面粉中為聚集分布。結(jié)論腐食酪螨在蕪湖市倉儲面粉中的自然種群季節(jié)性消長呈雙峰型,空間格局為聚集分布。
[Abstract]:Objective to study the seasonal dynamics of natural population and its spatial distribution pattern in stored flour in Wuhu city, and to provide theoretical basis for the control of typhus rot mite. Methods from 2013-1-2013-12, 5 sampling sites in Wuhu city were selected, and fixed spot sampling was carried out every month. The spatial distribution of Tyromite species in warehouse flour was studied by using the Iwao mm-x regression equation and Taylor LG S2-lg-x regression analysis. Results the peak of typhus rot mite in stored flour in Wuhu city was in July and September. The linear regression equation of the diffusion-type index I _ (0) C _ (0) / -x _ (1) I _ (wao) was 3.740 3 1.017 5-x(r=0.995 _ (8) 5-x(r=0.995 and Taylor's linear regression equation was (1) S _ (2) (0.500 4 1.134 9) lg-x(r=0.832 ~ (8), indicating that typhus putrescens were clustered in stored flour. Conclusion the natural population of Tyrophus putrescens in the stored flour of Wuhu City showed a double peak pattern of seasonal growth and fluctuation, and the spatial pattern was clustered distribution.
