Comparison of over-the-counter insecticides for managing the European earwig, Forficula auricularia L. (Dermaptera: Forficulidae)
Southwestern Entomologist 35 (1), 69-74
Abstract: There have been major changes in the availability of over-the-counter insecticides in recent years as older products (e.g., organophosphates and carbamates) have been largely supplanted by pyrethroids. To better understand how these newer materials may work in management of European earwig, Forficula auricularia L., a systematic evaluation was done of formulated pyrethroid insecticides that are currently marketed, comparing them to an established standard, carbaryl. Two of the tested insecticides, esfenvalerate and betacyfluthrin, did not produce significant mortality compared to the water check. Three active ingredients - permethrin, deltamethrin, and bifenthrin - produced significant mortality when tested at the marketed concentration but failed to provide significant mortality at 0.2X dilution. Carbaryl provided irregular control that was significant in only one of the two experiments. These data suggest that the concentration of the insecticides in these over-the-counter products presently sold at retail seems to be at or near the lower amount where earwigs can be controlled. Pre-mixed products containing lambda-cyhalothrin and bifenthrin provided significant mortality of European earwig at the marketed concentration and the lesser diluted rate.
