Evaluation of repellent activity of two essential oils and their mixed formulation against cockroaches (Dictyoptera: Blattidae, Blattellidae) in Iran

Idin Zibaee, Pooya Bahari Khorram and Majid Hamoni

The repellency of two essential oils extracted from the plant species Eucalyptus globulus, Rosmarinus officinalis and Naphthalene as a control, were evaluated for repellent activity against the three cockroach species Periplaneta americana (L.), Blattella germanica (L.) and Supella longipalpa under laboratory conditions. The mixture of two essential oil showed the best repellency over single essential oils (95%, 100% and 100% for P. americana, B. germanica and S. longipalpa respectively). The mixed formulation of essential oils exhibited complete repellency (100%) against longipalpa and B. germanica, and also showed the highest repellency (among the essential oils tested) of about 95% against P. americana under laboratory conditions. In the field, two essential oils as mixed formulation with 10% active ingredient in water and some other additives, provided satisfactory repellency of up to 97% reduction in cockroaches, P. americana, B. germanica and S. longipalpa with a residual effect lasting for a week after treatment. The results showed that mixture of two essential oils has good potential for being used as a cockroach repellent. Further improvements in efficacy and residual activity may be obtained with more appropriate formulations.
