Evaluation de deux méthodes de lutte intégrée contre les ravageurs en vergers d'agrumes
[Evaluation of two IPM methods to control main pests in citrus orchards]
Journal of Applied Entomology 127 (1), 51-63
Abstract: This study aims to the consolidation of the acquired knowledge regarding integrated pest management (IPM) against the main pests in citrus orchards. We provide evidence that the principles of this method already tested on small scales, are quite applicable on larger ones. In addition to this aspect, the purpose of our work has been the evaluation of two IPM methods: the first one, has been tested in Morocco for 3 years in areas not exceeding 1.2 ha; the second one originating from Australia, is presently recommended by the Plant Protection Authorities in Morocco. The results obtained confirm the complementarity between these two methods which are not mutually exclusive, despite some advantages recorded in favour of this method or the other. Our results show that the Moroccan method is more efficient in monitoring aphids and citrus leaf miner (CLM) population as it leads to the same results while reducing by half the number of the samples inspected. In contrast, mites monitoring is more convenient with the Australian method, allowing a good evaluation of the numbers of phytoseiid predators. Moreover, this method enabled us to reduce the quantity of pesticides used against Mediterranean fruit fly through treatment by lured spots reducing pulp volume by more than 92.8% and costs by 20%. These two methods gave the same results for monitoring population dynamics of California red scale and Mediterranean fruit fly but, fruit infestation at harvest was higher with the Australian method than the method developed locally (70.95% against 74.75 for California red scale and 2.35 against 3.35 for Mediterranean fruit fly).
