摘要
[目的]明确宁夏枸杞2种瘿蚊科害虫(枸杞红瘿蚊Gephyraulus lycantha和枸杞白瘿蚊Contarinia sp.)的形态特征差异.[方法]采用显微镜和扫描电镜对2种瘿蚊不同虫态的形态特征进行观察对比,尤其是对体色,幼虫胸骨片,蛹背棘刺,成虫触角和生殖器等进行比较.[结果]2种瘿蚊的形态特征存在明显差别,枸杞红瘿蚊虫体橙红色,幼虫胸骨片"Y"形,蛹背具不规则短棘刺,雄成虫抱握器呈方形,无刚毛,雌成虫产卵针粗壮;枸杞白瘿蚊虫体白色,幼虫胸骨片"T"形,蛹背具规则长棘刺,雄成虫抱握器呈三角状、具长刚毛,雌成虫产卵针细长.[结论]宁夏枸杞2种瘿蚊科害虫在幼虫胸骨片、蛹背棘刺、成虫生殖器均具有明显的非同种形态特征差异,建议做进一步分类学研究.研究结果可为宁夏枸杞上两种瘿蚊的鉴定、监测、防治及其进一步研究提供参考.
Abstract
[Objective]This study aimed to clarify and compare the morphological characteristics of two gall midge pests(Gephyraulus lycantha and Contarinia sp.)on Lycium barbarum.[Method]Microscopic and scanning electron microscopic techniques were employed to observe and compare the morphology of dif-ferent stages and body parts of the two gall midges.Specifically,the body color,larval sternum slices,dorsal spines of the pupa,antennae,and genitalia were examined and compared.[Result]Significant differences were observed between the two gall midges.G.lycantha exhibited an orange-red body color,"Y"-shaped sternum in the larval stage,irregular short spines on the dorsal side of the pupa,square-shaped male adult grippers without setae,and stout oviposition needles in female adults.On the other hand,Contarinia sp.dis-played a white body,"T"-shaped larval sternum,regular long spines on the dorsal side of the pupa,triangular male adult grippers with long bristles,and long and thin oviposition needles in female adults.[Conclusion]The distinct differences observed in terms of larval sternum slices,dorsal spines of the pupa,and adult geni-talia between the two gall midges suggest the need for further taxonomical studies.The findings of this re-search can serve as a valuable reference for the identification,monitoring,control,and future investigations of these two gall midge pests on L.barbarum.
