【摘要】：農(nóng)業(yè)景觀復(fù)雜性對昆蟲種群的影響是目前昆蟲生態(tài)學(xué)研究的熱點。新疆兵團和地方在土地利用模式及作物景觀上存在著明顯的差異,這可能影響昆蟲種群動態(tài)及其管理策略。在兵團和地方的不同試驗點,應(yīng)用智能測報燈、殺蟲燈誘集監(jiān)測在地區(qū)尺度和區(qū)域尺度旋幽夜蛾Scotogramma trifolii種群動態(tài),結(jié)合各樣點作物種類及面積調(diào)查,分析旋幽夜蛾種群動態(tài)與景觀復(fù)雜性之間的關(guān)系,研究結(jié)果表明:(1)在地區(qū)尺度上,簡單景觀條件下旋幽夜蛾誘集量小于復(fù)雜景觀,不同調(diào)查半徑下旋幽夜蛾誘集量與景觀多樣性指數(shù)(Shannon-Wiener)呈顯著正相關(guān)(P0.05);(2)在區(qū)域尺度上,兵團作物體系內(nèi),南疆的旋幽夜蛾誘集量小于北疆,并且存在顯著性差異;地方作物體系內(nèi)南疆的旋幽夜蛾誘集量大于北疆,同樣存在顯著性差異;在南疆地區(qū),兵團和對應(yīng)地方的誘蛾量均呈現(xiàn)顯著性差異(P0.05),在北疆地區(qū),兵團與對應(yīng)的地方之間無顯著性差異(P0.05),這可能與北疆地區(qū)兵團和地方在土地利用模式及其作物布局趨于一致有關(guān)。
[Abstract]:The influence of agricultural landscape complexity on insect population is a hot topic in insect ecology. There are obvious differences in land use patterns and crop landscape between Xinjiang Bingtuan and local areas, which may affect insect population dynamics and management strategies. The population dynamics of Scotogramma trifolii in regional scale and regional scale were monitored by intelligent forecasting lamp and insecticidal lamp in different experimental sites of Bingtuan and local, and the species and area of crops were investigated. The relationship between population dynamics and landscape complexity of Spodoptera exigua was analyzed. The results showed that on the regional scale, under simple landscape conditions, the amount of attraction of Spodoptera exigua was smaller than that of complex landscape. Under different investigation radii, there was a significant positive correlation between the amount of Spodoptera exigua and the landscape diversity index (Shannon-Wiener2). On the regional scale, in the crop system of Xingtuan, the amount of trap was smaller in the southern Xinjiang than in the north, and there was significant difference. There was also significant difference in the amount of moth trap between southern Xinjiang and corresponding area in southern Xinjiang, and in northern Xinjiang, there was a significant difference in the amount of moth trap in southern Xinjiang and corresponding areas, while in northern Xinjiang, there was a significant difference in the amount of moth trap between the southern Xinjiang and the corresponding areas, and in the north of Xinjiang, there was a significant difference in the amount of moth trap between the two regions. There was no significant difference between the bingtuan and the corresponding places, which may be related to the pattern of land use and crop distribution in the northern Xinjiang area.
