红花指管蚜虫对顶羽菊植物趋向性调查研究

Investigation on the Tropism of Safflower Finger-tube Aphid to Acroptilon Repens

2017—2020年对新疆乌鲁木齐北部山区、昌吉、伊犁、塔城的红花产区以及云南产区进行实地调查,重点观察红花种植地块及其周边顶羽菊的分布、红花指管蚜虫数量及其分布,探索红花指管蚜虫对顶羽菊植物具有趋向性这一现象存在的普遍性,为红花生态种植中防治红花蚜虫和顶羽菊提供新思路。结果表明:生长在红花地中的顶羽菊植株上密集着红花指管蚜虫,而相邻的红花植株上鲜有见到。说明与红花相比,顶羽菊对红花指管蚜虫具有更强的趋向性(正趋性)。调整研究结果对红花的生态种植及虫害草害防治具有重要意义。

Field investigation was conducted on the safflower producing areas in the northern mountainous areas of Urumqi,Changji,Yili and Tacheng,as well as the producing areas in Yunnan,focusing on the distribution of Acropti⁃lon repens in safflower planting plots and their surrounding areas,and the presence and distribution of Uroleucon go⁃bonis.The aim is to clarify the universality of the phenomenon that the Uroleucon gobonis tend to Acroptilon repens plant,and to provide a new idea for the control of Uroleucon gobonis and Acroptilon repens in the ecological cultiva⁃tion of Safflower.The results showed that Uroleucon gobonis were concentrated on the Acroptilon repens plants grow⁃ing in the safflower field,but seldom on the neighboring safflower plants.These results indicated that Acroptilon re⁃pens had a stronger positive tendency to Uroleucon gobonis than safflower,which was of great significance for ecologi⁃cal planting and pest control of safflower and the control of insect pests and weeds.
