2022年EPG廠家培訓

時間：12.11-12.13，地點：墨爾本（澳大利亞）

當地負責人：

Piotr Trebicki & Isabel Valanzuela（奧地利）

項目負責人：

Freddy Tjallingii（荷蘭），Elisa Garzo & Alberto Fereres（西班牙）

尊敬的同行：

什么是EPG（刺探電位圖）技術？

      將植物和昆蟲（大多是同翅目昆蟲）分別通過植物電極和昆蟲電極連接，構成連通電路的一部分；植物電極插入植物生長的土壤中，而昆蟲電極是通過銀膠將一根非常細的金線粘在昆蟲的背板部位而形成。當昆蟲借助刺吸式口器取食植物時，由于口器刺入植物組織的部位不同，以及昆蟲的活動（機體活動、吸食或流涎），導致連通電路的電勢差變化，即波形的波動。通常情況下，可以一次記錄持續8小時的8個重復實驗（可能還有更多的實驗配置方法）

     EPG常用于研究植物與昆蟲之間的相互作用，包括植物抗性、宿主植物識別、植物病原體傳播、植物防御的電生理方面等。

課程內容：包括講座（上午）和實操（下午），在法拉第籠中使用、昆蟲和植物的布線安裝、監測記錄（數據采集）、信號分析、數據處理和統計分析方向。

參會人數有限：由于設備和設施的限制，參會者最多16人，若有更多人注冊，將會使用候補名單。

會議費：

500澳元（約人民幣2500元）

參會方式：回復郵件如下或直接回復當地負責人

Dear colleague,

What is the EPG (Electrical Penetration Graphs) technique?

A plant and a (mostly) Homopteran insect are made part of an electrical circuit by using a soil electrode for the plant and gluing a very thin gold wire to insect’s dorsum. Upon plant penetration by the insect, electrically caused waveforms indicate tissue positions of the stylet tips and insect activities (mechanical movements, ingestion, or salivation). Typically, 8 replicates can be recorded for periods up to 6-8h (more experimental configurations are possible).

EPG recording is commonly used to study plant-insect interactions as involved plant resistance, host plant recognition, plant pathogen transmission,  electrophysiological aspects of plant defenses, etc.

Course program: see attachment. This includes lectures (morning sessions) of and practical training (afternoon sessions) in Faraday case use, wiring and mounting insects and plants, monitored recording (data acquisition), signal analysis, data processing and directions for statistical analysis.

Number of participants limit. Because of equipment and facilities limitations there will be a maximum of 16 participants. When more people sign up a waiting list will be used.

Fees. 

Participants pay a fee of AUS $500
