- Mating disruption trials for the olive moth, Prays oleae (Bern.), (Lep.: Yponomeutidae) in Trás-os-Montes olive groves (Northeast of Portugal).Publication . Bento, Albino; Pereira, J.A.; Cabanas, J.E.; Konstantopoulou, Maria A.; Torres, L.; Mazomenos, Bassilios E.The olive moth, Prays o/eae (Bern), is one of the most serious olive pests in the Mediterranean basin. The objective of the present study was to integrate environmentally safe methods for the control of the pest. Trials were carried out for three consecutive years (2002-2004) in an olive grove about 20 ha, in the ecological production region at Romeu (North of Mirandela).

- Prospects to use releases of the egg parasitoid Trichogramma (Hymenoptera, Trichogrammatidae) for biological control in olive cultivation – lessons from the EU-project “Triphelio“.Publication . Herz, A.; Hassan, Sherif Ali; Hegazi, Esmat Mohamed; Hafez, B.; Nasr, Feeby N.; Youssef, A.; Agamy, Essam A.; Jardak, Taieb; Ksantini, M.; Konstantopoulou, Maria A.; Mazomenos, Bassilios E.; Broumas, T.; Milonas, P.; Moschos, T.; Souliotis, C.; Torres, L.; Pereira, J.A.; Bento, Albino
- Towards sustainable control of Lepidopterous pests in olive cultivationPublication . Herz, A.; Hassan, Sherif Ali; Hegazi, Esmat Mohamed; Nasr, Feeby N.; Youssef, Ali A.; Khafagi, Wedad Emam; Agamy, Essam A.; Ksantini, Mohieddine; Jardak, Taieb; Mazomenos, Bassilios E.; Konstantopoulou, Maria A.; Torres, L.; Gonçalves, Fátima M.; Bento, Albino; Pereira, J.A.Current olive growing practices range from the traditional Mediterranean olive grove to intensively managed olive plantations. Insecticides against major olive pests, like the olive moth (Prays oleae, Lep.: Yponomeutidae) and the jasmine moth, (Palpita unionalis, Lep.: Pyralidae) are still applied frequently. The European Union-funded international research project TRIPHELIO is aimed at the development of economically feasible and sustainable insecticide-free control methods for key Lepidopterous pests of olive. Main research activities focus on (1) the use of pheromones for mating disruption and improved monitoring of target pests, (2) habitat management strategies to enhance the activity of natural enemies in the olive grove, and (3) the use of inundative releases of mass-reared egg parasitoids of the genus Trichogramma. Moreover, tools for successful integration of the methods developed into an integrated pest management (IPM) strategy for olive pests were explored by optimising techniques for surveillance as well as considering potential side-effects of common pesticides on beneficial organisms. An intense exchange of scientific information and technology between European and North African countries was undertaken to create solutions for a wide range of olive growing regions. Key results and recommendations for further essential steps towards practical implementation are presented in this publication.
- Triphelio – an international research project for sustainable control of lepidopterous pests in olive groves.Publication . Agamy, Essam A.; Bento, Albino; Hafez, B.; Hassan, Sherif Ali; Hegazi, Esmat Mohamed; Herz, A.; Jardak, Taieb; Ksantini, M.; Konstantopoulou, Maria A.; Mazomenos, Bassilios E.; Nasr, Feeby N.; Pereira, J.A.; Torres, L.; Youssef, A.The olive moth (Prays oleae, Lepidoptera: Plutellidae) is known as one of the key pests in olive cultivation. In particular areas, also the jasmine moth (Pal pita zmionalis, Lepidoptera: Pyralidae) can cause serious damage to both leaves and fiuits of the olive tree. Both pests are mainly controlled by insecticide applications. In November 200 I, an international research project was started to promote biological and biotechnical methods for the control of these pests.
