摘　　要：为明确自然条件下意大利蝗各龄期的食性,于2021年利用嗉囊显微分析技术研究了雅玛里克山意大利蝗蝗蝻的食性,计算其取食选择性,明确其龄期和两性食性差异,并利用生态位分析揭示其潜在的种内竞争关系。结果表明:自然条件下意大利蝗蝗蝻可取食5个科的9种植物,其中1~3龄取食的植物种类最多、为7种;4~6龄取食种类逐渐减少。蝗蝻多取食双子叶植物,且多取食菊科和藜科植物。蝗蝻多主动取食大籽蒿、新疆绢蒿和木地肤;1~5龄蝗蝻会随机取食驼绒藜;部分龄期的蝗蝻被动取食牛蒡、小蓬、新麦草和拉拉藤。1龄和3龄最喜食新疆绢蒿,2龄和5龄最喜食木地肤,4龄和6龄最喜食大籽蒿。雌雄蝗蝻两性间,1~2龄对9种植物的取食无显著性差异;而3~5龄蝗蝻对大籽蒿、新疆绢蒿和驼绒藜的取食表现显著的两性差异。1龄和5龄蝗蝻的两性间存在潜在竞争;5龄蝗蝻与其他龄期蝗蝻存在潜在竞争。s:This study aims to elucidate the feeding habits of Calliptamus italicus L.at all instars under natural conditions.The feeding tendencies of C.italicus nymphs in Yamalike Mountain were studied through crop microanalysis in 2021,and the feeding selectivity was calculated using Ivlev's selection index.The differences in instars and feeding habits between genders were clarified,and the potential for intraspecific competition was revealed through niche analysis.The results showed that the nymphs of C.italicus exhibited the capacity to feed on 9 types of plants belonging to 5 families under natural conditions.The Ist to 3rd instar nymphs feed on a maximum of seven species,and the number of plant species fed on by nymphs of the 4th to 6th instars decreased gradually.The nymphs exhibited a preference for dicotyledons,with a particular inclination for plants belonging to the Asteraceae and Chenopodiaceae families.The majority of locust nymphs were observed to feed actively on Artemisia sieversiana Ehrh.ex Willd.,Seriphidium kaschgaricum(Krasch.)Poljak.,and Bassia prostrata(L.)Beck.Furthermore,the Ist to 5th instar nymphs will randomly feed on Krascheninnikovia ceratoidess(L.)Gueldenst..Some of the nymphs were observed to feed passively on Arctium lappa L.,Nanophyton erinaceum(Pall.)Bunge,Psathyrostachys juncea(Fisch.)Nevski,and Galium spurium L..The Ist and 3rd instar locusts exhibited a clear preference for S.kaschgaricum,while the 2nd and 5th instar locusts favored B.prostrata,and 4th and 6th instar locusts displayed a marked predilection for A.sieversiana.No significant differences were observed in the feeding behavior of the 9 plant species between male and female nymphs of the Ist and 2nd instars.However,a significant gender difference was evident in the feeding behavior of the 3rd,4th,and 5th instar nymphs,with males and females showing distinct preferences for A.sieversiana,S.kaschgaricum,and K.ceratoides.There was a potential competition between the sexes in the lst and 5th instars.A potential competition was id
