Jose Eduardo Belda (Koppert), Jose Alberto Pereira (IPB Bragança) Alberto Fereres (ICA-CSIC), Leandro Pena (CSIC) and Amilcar Duarte (UaDlg) in Algarve, Oporto area and Estación Fitopatolóxica Areeiro (EFA) to continue with the monitoring and evolution of the objectives set within PRE-HLB.

These meetings were held for the continuation of the trials established in relation to the application of Kaolin, plastics in soil and the study of fungi that eat Trioza (entomapatogenic).

Alberto Fereres is coordinating experiments on the life cycle and host range of Trioza erytreae in collaboration with the Arthropods and IPM Laboratory from the Estación Fitopatolóxica Areeiro, which belongs to the Diputación de Pontevedra. Currently, the researchers are designing the following experiments to be carried out in Oporto and Pontevedra.

The actions to be carried out in the EFA facilities are focused on:

  • Mass rearing of the insect Trioza erytreae. The trials involve laboratory and field work and will involve achieving a stable and continuous rearing of the insect on lemon trees.
  • Studies on the life cycle and the maximum and minimum development thresholds of t. erytreae. The rate of development, survival, longevity and reproduction (calculation of fecundity and fertility rates) of the insect at different temperatures and relative humidity are being studied.
  • T. erytrae preference tests on different plant species.
  • Laboratory efficacy of biological insecticides. In this case, different control trials are being carried out with entomopathogenic fungi to determine their activity against the pest, their dose-response behavior and their persistence, with the aim of integrating them into pest/HLB management strategies.
