Abstract
Due to the immense important of it has, cochineal insect was introduced to Tigray Regional State of Ethiopia. However, due to wild use of this insect, the cactus pear which is the integral part of economy of the people is being destroyed. Let alone to get additional benefit which was assumed during the introduction of this insect, the enormous benefits of this fruit which have been for many years is being lost. Currently, the people of Tigray, especially, the northern part lost their whole cactus pear. What makes it more sever is that, the insect is rapidly expanding to the rest of the area where cactus pear and the people are highly interconnected. This study was aimed to evaluate the efficacy of natural oils from Eucalyptus against cochineal insect. The essential oil used here was obtained by hydro distillation from fresh Eucalyptus camaldulensis leaf. The oil recorded high insecticidal activity both in laboratory and spray test. Death time for young male and female was 38±10, 80±15 min respectively. Corresponding sex adults die at 72±13and 86±14 at higher concentration (100µl/air). In three days spray of 600 µl/air oil all insects of all ages were eliminated.
