摘要: 蓟马在韭菜上发生十分严重,影响了韭菜的产量和品质。本文鉴定了韭菜上蓟马的种类,研究了蓟马在韭菜田间的危害症状、发生规律以及防治方法。试验结果表明韭菜上的蓟马形态特征为西花蓟马,ITS分子鉴定结果显示扩增片段520bp,与西花蓟马的碱基序列相似度达到99.81%。西花蓟马在韭菜田间离地80cm高度的空间分布较集中;晴天时,在下午15:00~17:00时间段上西花蓟马出现频率较高;雨水对西花蓟马的致死作用明显,致死率为29.30%;田间防治试验筛选出20%呋虫胺可溶性粒剂和40%啶虫脒粒剂对田间韭菜西花蓟马的防治效果较好,其中20%呋虫胺可溶性粒剂1500倍液的喷雾防治效果最佳,达92.56%。

Abstract: The paper aims to identify the species and regularity of thrips happened on leek, and to study the main control methods. The authors identified thrips species by morphological and molecular methods, and studied the damage symptoms, biological characteristics, occurrence regularity and control methods of thrips in the field of leek. The results showed that: the morphological characteristic of thrips on leek was Frankliniella occidentalis (Pergande), the results of ITS molecular identification showed that the amplified fragment 520 bp was similar to that of the F. occidentalis, and the similarity of the base sequence was 99.81%; the space distribution of F. occidentalis in the field from the height of 80 cm was relatively concentrated; on sunny days, the thrips appeared more frequently during 15:00-17:00; the lethal effect of rain on thrips was significant, the death rate was 29.30%; the results of field efficacy trials indicated that dinotefuran 20% soluble granules and 40% dacetamiprid granule had good control effects on leek thrips, and the control effect of 1500×diluted solution of 20% dinotefuran soluble granule was the best, up to 92.56%.
