A brief RF pulse of about 20 watts is delivered via a fine tungsten needle to give a highly localized burn. It can cut the stylet or labium of a grazing aphid, or cauterize other tissue, in a volume according to the thermal properties of the tissue and the geometry of the needle. The Zapper is in routine use in laboratories world-wide. RF micro-cautery gives a versatile,
reliable and inexpensive method to collect sieve tube sap. |
