1.烟潜叶蛾属鳞目、麦蛾科,学名经请中国科学院昆虫研究所朱弘复教授鉴定,是Gnorimoschema operculella(Zeller)。 2.至今据有关农业机关调查;烟潜烟蛾在我国分布已有6省、82县(市)以上。 3.寄主以茄科植物为主,计有烟草、茄、马铃薯、番茄、辣椒、蔓陀萝、刺菜。在贵定一带一年发生5个完整的叠置世代;越冬虫态有卵、幼虫、蛹、成虫;越冬处所是烟、茄楂地及地边烟杆堆处,农家马铃薯贮藏处所较少。 4.烟潜叶蛾在烤烟本田生长期发生两个叠置世代;前期为害轻,后期为害重。自2月下旬以至3、4月间马铃薯、烟相继萌芽生长,越冬的烟潜叶蛾迁移过来,烟移植了苗床期也就结束、马铃薯也将收获完毕,此后即迁移到烟本田里,这是按据烟潜叶蛾在主要寄主植物间的消长,认为是这样迁移的。 5.烟潜叶蛾的主要习性是:成虫具慕光性,夜晚活动,产卵于脚叶及烟株茎基部,散产,也有2—3粒产在一起的。卵多于清早孵化,初孵化的幼虫多在叶片或茎上,活动2至149分钟不等,才开始蛀叶取食。幼虫主要是集中为害脚叶,潜痕因故破裂时,多行迁移。化蛹在地面、脚叶、或茎基部、地面残枝树叶上。 6.进行防治以拔除处理烟、茄楂杆,并厉行秋耕,可为治本办法。他如提前移植,结合耕作管理打除处理胎叶,用0.01％γ-666或1％DDT液剂在初龄幼虫期喷药
1. Smoke sub-leaf moths scales, wheat moths, scientific name invited by the Chinese Academy of Sciences Institute of Entomology Zhu Hongfu identification is Gnorimoschema operculella (Zeller). 2. So far, according to the investigation of relevant agricultural agencies; smoke submerged moth distribution in our country has 6 provinces, 82 counties (cities) above. Host to the solanaceous plants, accounting for tobacco, eggplant, potatoes, tomatoes, peppers, Mandragorata, stichopus. There are 5 complete overlapping generations in the Guiding area. There are eggs, larvae, pupae and adults in the overwintering state. Tobacco, hawthorn and land stems are located in the overwintering area. 4. Tobacco leaf moths in the flue-cured tobacco Honda two overlapping generations of growth; early light damage, the late damage. From late February to March and April, potato and tobacco germinated in succession, and the overwintering tobacco leaf miner migrated. After the tobacco transplant, the seedbed period was over and the potato was also harvested, and then moved to the tobacco field. According to tobacco leaf moths in the main host plants between the growth and decline, that is so migrated. 5. The main habits of tobacco leaf moths are: adult with light, activity at night, spawning in the foot of leaves and tobacco plant stem base, casual, there are 2-3 grain together. Egg more than hatch early in the early hatching of larvae or more leaves or stems, activities ranging from 2 to 149 minutes before beginning eel leaf feeding. The larvae mainly focus on the damage to the foot, latent marks rupture for some reason, multi-line migration. Pupae on the ground, feet, or stem base, the ground branches on the leaves. 6. Prevention and control to remove the handling of tobacco, hawthorn rod, and the implementation of autumn plowing, for the cure this approach. If he transplanted in advance, combined with farming management to get rid of dealing with fetal leaves, with 0.01% γ-666 or 1% DDT liquid in the first instar larvae spraying
