Abstract

ABSTRACT The weevil Conorhynchus kindermanni Faust, 1904 (Curculionidae: Lixinae: Cleonini) was detected in close association with Salsola tragus L. (Amaranthaceae) in Ağrı Mountain soutwestern lowland area where sandy desert. The aim of this study is to determine the life cycle of C. kindermanni feeding on S. tragus. The field research was conducted between Iğdır and Doğubayazıt district of Ağrı Province Turkey in the summer of 2020. According to the results, adults of C. kindermanni feed on S. tragus starting on the rosette stage of this weed. Mating occurs on the ground among young plants, and eggs were laid on roots attached with a glue-like secretion. The legless larvae are freely able to move in sandy soil to reach lateral branches of roots for feeding. The mature larva prepares a solitary soil-case for pupal development in the soil near the host plant root. New generation adults hibernate inside the chamber until emergence from soil in early spring. This species produces one generation in a year in the Ağrı Mountain lowland desert habitat.

Ağrı山地低地地区食草小蛾(Conorhynchus kindermanni Faust, 1904)的生物学观察

摘要/ ABSTRACT摘要:在西南沙质荒漠Ağrı山区低地地区，发现了1904年的幼童象(Conorhynchus kindermanni Faust)，与苋科(Salsola tragus L.)亲缘关系密切。本研究的目的是确定幼童C.以黄花葡萄为食的生命周期。实地调查于2020年夏季在土耳其Ağrı省Iğdır和Doğubayazıt区进行。结果表明，幼童小蠊成虫从莲座期开始就以黄花小蠊为食。交配发生在地面上的幼嫩植物之间，卵产在附着胶状分泌物的根上。无腿幼虫能在沙土中自由移动，到达根的侧枝取食。成熟幼虫在寄主植物根系附近的土壤中为蛹发育准备一个单独的土壳。新一代成虫在室内冬眠，直到早春从土壤中出来。这个物种在Ağrı山地低地沙漠栖息地一年生产一代。关键词:金曼大孔雀鱼，耳草，杂草，生物观察，Ağrı
