Control fitosanitario de glycaspis brimblecombei moore., que afecta al Eucalyptus citriodora hook., en los predios de la Espoch

Abstract

Glycaspis brimblecombei is a pest that threatens varieties of red Eucalyptus in Ecuador and causes their death; however, there is no adequate management of this pest. This study aimed to control G. brimblecombei that affects Eucalyptus citrodora on ESPOCH properties. For this work, two methods of applying the systemic insecticide Imidacloprid were tested with a motor backpack and drilling into the soil near the roots. To apply conservative biological control, strips of flowering plants were implemented around the affected trees. Seeds and cuttings of flowering plant species were collected on-site. Germination tests were carried out on the plant seeds with thermal shock, leaching, and a control. They were propagated with the best treatment and taken to the area of the affected trees to make the beneficial insects interact with the plants and increase their population. Regarding the results obtained in the application of Imidacloprid, the best control was obtained with fumigation with the motor backpack, receiving an 11.36% reduction in damage to the leaves. On the other hand, in the pre-germinative treatments applied to 25 species, the species with the highest percentage of germination were chosen, and six species were propagated sexually and four asexually. Strips with flowers were implemented in order to enhance conservative biological control. In conclusion, it is possible to say that chemical control method 1 was better in terms of the propagation of flowering plants; the five species with the greatest potential were chosen, and the strips were implemented around the affected trees.
