内蒙古草原蝗虫个体大小及生活型划分的探讨

根据内蒙古锡林河流域草原蝗虫的形态测量指标，对２３种蝗虫进行了个体大小及生活型量化划分的探讨，结果表明，２３种蝗虫可以划分为大、中、小３个类群，生活型表现为从典型的地栖型到典型的植栖型的渐为特征。个体在小与生活型紧密相关，个体大的种类常为地本型，而个体小的种类多为植栖型。

STUDIES ON THE INDIVIDUAL SIZE GROUP AND THE LIFE FORM OF GRASSHOPPERS IN TYPICAL STEPPE OF INNER MONGOLIA,CHINA

The life form and the individual size group of grasshoppers in typical steppe of Inner Mongolia were dealt with based on morphometric data(length of body,height of body,width of body,length of tegmen,length of post femur,length of pronotum,length of post tibia,miximum width of head).The results show that 23 species of grasshoppers could be divided into three groups as follows: (1) large size group,only one species,i.e. Haplotropis brunneriana Sauss.(HBS) (2) medium size group,including Pararcyptera microptera meridionalis .(Ikonn)(PMM), Mecostethus grossus (L.)(MGL), Bryodemella tuberculatum dilutum (Stoll)(BTD), Oedaleus asiaticus B Bienko(ODA), Celes skalozubovi (Adel).(CSA), Bry ode mella holdereri holdereri (Krauss)(BHK), Angaracris rhodopa (F. W.)(ARF), A.barabensis (Pall.)(ABP) (3) smallsize group,including Calliptamus abbreviatus (Ikonn).(CAI), Gomphocerus licenti (Chang)(GLC), Chrysacris albovitattus (Li)(CAL), Ch.albomarginatus (De Geer)(CAD), Chorthippus brunneus (Thunb.)(CBT), Eremippus simplex simplex (Ev.)(ESS), Dasyhippus barbipes (F. W.)(DBF), Omocestus haemorrhoidalis haemorrhoidalis (Charp.)(OHH), Ch.dubius (Zub.)(CDZ), Aeropedellus variegatus minutus Mistsh.(AVM), Myrmeleotettix palpalis (Zub.)(MPZ), Ch.fallax (Zub.)(CFZ), Ch.hammastoremi (Mir.)(CHM), Mongolotettix japonicus vittatus (Uv.)(MJV). The life form of grasshoppers from terricoles to planticoles were as follows: Female:HBSBTDBHKSACABP,ARFODAPMMCAIGLCMGLOHHCBTCDZ,DBFCHMESSAVMMPZ,CADCFZMJVCAL. Male:HBSBHKBTDARF,ABPCSAPMMODAGLCCAIMGLAVM,DBFOHHCBTESSCDZ,CHMCADCFZMPZMJV. The results also show that life form connected with individual size.The larger was typical terricoles(eg,HBS),the smaller was typical planticoles(eg,MJV).
