| 3. | There was a positive relationship between the uniformity degree of the piemarker distribution in field and attractive rate 在棉花和大豆的整个生长期间,苘麻对烟粉虱均有极显著的诱集作用,但不同播期苘麻的诱集效果差别明显。 |
| 4. | The searchlight trap was found to be an efficient tool for trapping migrants and , operated alongside a ground light - trap , could distinguish migrant from locally - flying species 探照灯诱虫器能有效地诱集迁飞昆虫,与地面灯诱虫器同时使用可以将迁飞昆虫从当地繁殖的昆虫种类中区分出来。 |
| 5. | The attractive efficiency from single interplanting piemarker was 3 - fold and 7 - fold high as compared to the planting types of the strip interplanting and plot interplanting 在棉花和大豆生长早期,烟粉虱最先在早播的苘麻上发生,诱集效果达85 . 2 % ;中播和晚播苘麻对棉花和大豆生长中、后期的烟粉虱诱集效果显著,分别达到93 . 3 %和95 . 4 % 。 |
| 6. | The insecticide application of 25 % thiamethoxam wdg , 5 % fipronnil sc , 25 % buprofezin wp 10 % beta - cyperethrin lc , and 25 % phoxim lc on piemarker plants , showed different control effects on sucking insect pests in cotton fields 苘麻植株在田间分散程度和诱集效果呈正相关,单棵插花种植苘麻的诱集效果分别是片状种植和条带种植苘麻的7倍和3倍。 |
| 7. | Thirty - nine pure isolates and eighteen pure cultures were obtained , of which five pure cultures were registered in the european bank of the glomales ( beg ) . a germplasm stock was established for storage of the resources in the target area 原始样品经过诱集培养、分离纯化后,得到39个纯净菌株, 18个纯株,在欧洲菌藏中心登记5个菌株,在此基础上初步建立了菌种保藏室。 |
| 8. | Among the insecticides tested , 25 % thiamethoxam wdg and 5 % fipronnil sc gave best results in terms of maximum mortality of this pest in cotton and soybean crops . conclusion piemarker as a trap plant in cotton and soybean field can play an important role in the integrated management of b . tabaci 基于播种期、种植方式和配套合理的药剂防治的苘麻诱集方法对生态调控棉田和大豆田中的烟粉虱发挥了积极的作用。 |
| 9. | According to basic principle and application experience of black light lamp , the trapping lamps were opened out using the principle of wave , color and taste to trap insect pests imago with the electric networks of frequently vibration and high voltages , it can trap many species and amounts of insect pests , reduce amounts of field ovum , greatly reduce insect pests density , save energy , have low lost , little harm to natural enemy and persons and livestock , have remarkable economic , ecological and social efficiency 摘要借鉴黑光灯的基本原理和应用经验,再配以频振高压电网触杀的频振式杀虫灯,诱集的害虫种类多、数量大,既大幅度降低了田间落卵量,又显著减少了虫口密度;节能省电,成本低;叶昆虫天敌杀伤力较小,对人畜安全,不污染环境,具有显著的经济、生态和社会效益。 |
| 10. | At the present time the prediction method of attracting pest with black light and recognizing and counting by man is generally adopted . there are some serious shortages such as bad recognition accuracy and low efficiency . it reduces seriously accuracy and timeliness of prediction and is disadvantage in guiding insect disease prevention 目前普遍采用的黑光灯诱集害虫、人工识别计数的测报方法,存在识别准确性差、效率低等严重缺陷,极大地降低了测报的准确度和时效性,不利于指导农田害虫的防治工作,因此本文提出了基于机器视觉和小波分析的图像识别技术,用于农田害虫的自动检测预报。 |
