1 October 2013 Harmonic Radar Tagging for Tracking Movement of Nezara viridula (Hemiptera: Pentatomidae)

Harmonic radar tagging was investigated as a method for monitoring the movement of the southern green stink bug, Nezara viridula (L.) (Hemiptera: Pentatomidae). Because adhesive toxicity and tag weight limit the use of this technology, initial efforts focused on selection of the optimal adhesive and design of harmonic radar tags to reduce impact on the movement of stink bugs. A design consisting of a 6-cm-long 0.10-mm-thick silver-plated copper monopole on the anode terminal of a three-contact Schottky barrier diode attached with Gorilla super glue provided a compromise between unimpaired movement and tracking range, adding an additional 8% to the weight of the stink bug while not significantly (P > 0.05) reducing walking or flying mobility in the laboratory. Recovery of tagged stink bugs in cotton, Gossypium hirsutum (L), and fallow fields ranged from 10 to 75% after 24 h, whereas marked stink bugs were recovered at rates of 0–35% by using sweep net or drop cloth sampling. The distance dispersed in the field was not impacted (P > 0.05) by crop, tagged status, or gender of the insect. Future research should examine possible improvements to the harmonic radar transceiver and the wire antenna to decrease encumbrance.
