1. Μπαρμπετάκη, Αφροδίτη. Είδη του γένους Orius ως παράγοντες βιολογικής καταπολέμησης εντόμων εχθρών κηπευτικών καλλιεργειών.

Degree: 2011, Agricultural University of Athens; Γεωπονικό Πανεπιστήμιο Αθηνών

The purpose of this study was both to record and classify the species of the genus Orius found in Greece, explore the range of plants on which they are found and examine in further detail the effect of temperature, host plant and prey species on some aspects of their life cycle. Counted and identified nine species: O. pallidicornis, O. laevigatus and O. niger, O. minutus O. horvathi, O. vicinus, O. majusculus, O. laticollis and O. albidipennis. Based on the criteria of domination and frequency, the most commonly collected species, was O. niger, followed by O. laevigatus, these characterized as dominant species. From the collected species, O. pallidicornis presents some specificity relation to the plant that is found. O.niger and O. laevigatus were collected on both cultivated and on non-cultivated plants. O. niger showed the widest geographical spread. O. laevigatus and O. vicinus were recorded mainly in central and southern Greece. In the present study the biological and demographic characteristics of individuals of O. vicinus and O. niger were investigated. The aphid M. persicae was used as a prey species and pepper and eggplant were used as host plants. The above research took place in the laboratory under the influence of six temperatures (15, 20, 25, 27.5, 30 and 32.5±1 °C). photoperiod 16L/8D and relative humidity 65 ± 5%. Both O. vicinus and O. niger completed their development at all experimental temperatures. Concerning the effect of temperature in reproduction of the two Orius species, the lowest egg deposition was observed at 15 °C and the highest in 25 °C for both plants. Both O. vicinus and O. niger are well adapted to low temperatures the optimal temperatures for their development are at 25 and 27.5 °C, while at high temperatures they have the potential to grow rapidly. O. vicinus showed significant differences in both the longevity and reproductive capacity of females, which showed higher values in the pepper over the eggplant. This makes pepper more favorable as host plant for O. vicinus. O. niger did not show any evidence of obvious preference for either plant species. In the present study the effect of prey species in the biological and demographic characteristics of individuals O. vicinus and O. niger were examined. Tetranychus urticae and Frankliniella occidentalis were used as prey, pepper as a host plant at temperature 25±1 °C, 16L/8D and relative humidity of 65 ± 5%. O. vicinus and O. niger complete successfully their development on both prey species. From the study of the biological and demographic characteristics of the two predators, we become aware that both predators have high adaption on both prey species. As for the two prey species both O. vicinus and the O. niger showed preference to the mite T. urticae.

Σκοπός της παρούσας μελέτης είναι, αφενός να καταγραφούν και να ταξινομηθούν τα είδη του γένους Orius που απαντώνται στον ελλαδικό χώρο και να διερευνηθεί το φάσμα των φυτών επί των οποίων ανευρίσκονται και αφετέρου να μελετηθούν λεπτομερέστερα οι επιδράσεις της θερμοκρασίας, του…
