We designed and tested a custom-made parasitoid emergence trap that can be installed on macadamia trees in the field to study parasitism of macadamia felted coccid, Acanthococcus ironsidei (Williams) (Hemiptera: Eriococcidae). The cost of materials for the trap is approximately $3.00 each, and a trap can be constructed in ~15 min. Optimal methods for determining percent parasitism using these traps are still under development, but two proposed methods gave estimates of 0.24 and 4.85% for mortality due to parasitism by Encarsia lounsburyi (Hymenoptera: Aphelinidae). The trap could be an effective and low-cost tool for future parasitism studies or in determining population structure of macadamia felted coccid as it captures parasitoids and other mobile, positively phototactic insects that are present under the covered area of the trap.
