| 摘 要： | 野外条件下，对意大利蝗（Calliptamus italicus）的取食特性、食量进行了研究；同时用笼罩和模拟方法测定了意大利蝗对田间产草量造成的损失。研究结果表明：意大利蝗若虫喜食冷蒿（Artemisia frigida Willd.）、针叶苔草（Carex onoei Franch. et Sav.）；而成虫则喜食冷蒿、新疆鼠尾草（Salvia deserta Schang）、黄花苜蓿（Medicago falcata Linn.）。意大利蝗3、4、5、6龄若虫以及成虫日平均食量分别为14.27、18.77、20.80、27.65、29.26 mg/头；在4、8、12、16头/m2密度下，笼罩产草量损失分别为5.66、16.45、26.78、26.41 g/m2；模拟产草量损失分别为6.23、19.40、26.65、30.85 g/m2。相关性分析结果表明，两者显著相关。上述结果对于指导意大利蝗的防治和更有效地控制意大利蝗的危害具有非常重要的意义。 |

| Abstract: | Food selection and consumption of Calliptamus imlicus under natural conditions were studied,and the yield losses caused by C.italicus as well as compensation capacity of forage were evaluated through the method of cover cage and artificial simulation.The results showed that the nymphs of C.italicus preferred Artemisia frigida Willd and Carex onoei Franch et Sav,while its adults preferred riot only A.frigida Willd,but Salvia deserta Schang and Medicago falcata Linn.The average food consumption of nymphs from 3rd to 6th iustars and the adults in a single day was 14.27,18.77,24.80,27.65 mg and 29.26 mg,respectively.The yield loss of grass using cover cage method was 5.66,16.45,26.78 g and 26.41 g,respectively,when the population density of C.italicus was 4,8,12 and 16 indivicluals/m~2,while using artificial sinmlation method,it was 6.23,19.40,26.65 g/m~2 and 30.85 gm~2,respectively.These results were of great significance to controllingthe damage of C.italicus. |
