The data were analyzed using SPSS software(version 20).Results: The results indicated that there was a significant difference between neem with juniper and eucalyptus at the 2.5% and 5.0% concentrations(P < 0.05), whereas there was a significant difference between all three extracts at the 10.0% concentration(P < 0.05).Conclusions: This is the first report on the repellent effect of these three plant extracts on Paederus beetles. Neem oil appeared to have the largest effect on Paederus spp. and juniper essential oil exhibited the second highest repellency, followed by eucalyptus.展开更多
