枣疯病媒介昆虫-中华拟菱纹叶蝉生物学和防治的研究

本文报道了中华拟菱纹叶蝉形态特征、生物学特性、传病规律、天敌及防治试验等研究结果。寄主植物除枣树及酸枣树外,尚有榆树。枣疯树上远比健树上为多。一年发生四代,但第四代只局部发生。以卵越冬。冬卵孵化及产生的若、成虫整齐而集中。在成虫接种试验中,只第一代饲病7天者传病。已初步发现六种捕食性天敌。试验证实,甲基1605、乙基稻丰散、杀螟松及敌敌畏等对卵及成虫有明显的杀灭效果。

ON THE BIONOMICS AND CONTROL OF HISHIMONOIDES CHINENSIS ANUFRIEV,THE VECTOR OF JUJUBE WITCHES''BROOM DISEASE

The Jujube witches'' broom disease has been regarded as a destructive disease of jujube.In areas where there was serious damage,70~80% of the jujube trees were infected or died,and so this disease has become the main problem in developing production of jujube trees.The discovery of the insect vector provides an effective approach for controlling the jujube witches'' broom disease. The host range of Chinese pseudorhombic marked leafhopper Hishimo-noides Chinensis Anufriev is very narrow.Besides the known hosts Zy-zus jujube Mill.and Z.spinosus Hu,the investigation to ten suspicious herbs and xylophytas showed that H.chinensis can also complete its life history on the elm (Ulmus pumila L.).
