“…had been recovered already in October 1975. This almost circure-mediterranean species had been released in continental Greece but not in Crete (Stavraki, 1970). The present rearings and catches therefore constitute the first record of C. eleaphila as an indigenous species of Greece.…”

BENEFICIAL INSECTS CAUGHT BY YELLOW TRAPS USED IN MASS‐TRAPPING OF THE OLIVE FLY, DACUS OLEAE

Under the conditions of a mass‐trapping experiment with 2 yellow sticky traps (YT)/small tree, 16 times as many parasitoids and predators as Dacus oleae (Gmel.) were caught. If only known parasitoids and predators of the main olive pest insects D. oleae, Saissetia oleae (Oliv.), Prays oleae Bern., and Aspidiotus nerii Bouché were considered, this ratio was reduced to 4 times. Olive flies (especially the males) were more abundant on the inner side of the YT, parasitoids and predators on the outer side and on traps in the eastern part of the canopy. This is interpreted as a higher flight activity of the beneficial insects as compared to D. oleae, particularly in the morning. Catches by traps on which half of each surface was painted either white, grey, or black, the other half being yellow, showed that — except for the night active chrysopids and coniopterygids — all parasitoids and predators were equally or better attracted to yellow than D. oleae. Other yellow or orange colours did not confer a higher specificity of the traps for the fruit fly. From absolute population estimates it is concluded that 3–5 YT/tree can virtually eliminate the beneficial fauna. ZUSAMMENFASSUNG Fang von Nutzinsekten durch Gelbfallen im Massenvernichtungsversuch gegen die Olivenfliege, Dacus oleae Unter den Bedingungen eines Massenvernichtungsversuchs mit 2 beleimten Gelbfallen/kleinem Olivenbaum wurden 16 mal mehr Parasiten und Prädatoren als Olivenfliegen gefangen. Wenn nur die bekannten Parasiten und Räuber der lokal wichtigsten Olivenschädlinge D. oleae (Tephritidae). Saissetia oleae (Coccidae). Prays oleae (Hyponomeutidae) und Aspidiotus nerii (Diaspididae)berücksichtigt wurden, verminderte sich dieser Wert auf 4 mal. Olivenfliegen (besonders die Männchen) wurden häufiger auf der Falleninnenseite, Parasiten und Räuber auf der Aussenseite und auf Fallen, welche im östlichen Teil der Baumkrone aufgehängt waren, gefangen. Dies wird so gedeutet, dass die Nutzinsekten häufiger im Olivengarten herumfliegen als D. oleae, und dies besonders am Morgen. Fänge an Gelbfallen, welche auf jeder Fläche zur Hälfte entweder, weiss, grau oder schwarz überstrichen waren, zeigten, dass — mit Ausnahme der nachtaktiven Chrysopiden und Coniopterygiden — alle Parasiten und Prädatoren gleich stark oder stärker als D. oleae von der gelben Farbe angezogen wurden. Auch andere Gelb‐und Orangefarbtöne vermochten nicht die Fallen für die Olivenfliege spezifischer zu machen. Anhand von absoluten Populationsschätzungen wird geschlossen, dass 3–5 Gelbfallen/Baum die Nützlingsfauna praktisch ganz zu vernichten vermögen.

“…), Platygaster mayetiole Kef., Platygaster apicalis Thoms. and Synopeas figitiformis Thoms (Stavraki 1970 There is little published information on the control measures against D. oleae with the use of pesticides, as chemical control has not been considered necessary in most cases. Arambourg (1986) has reported that spray applications of the organophosphorus insecticides fenthion, methidathion and chlorpyriphos in June gave the best results as compared with applications in March or April.…”

“…Pnigalio mediterraneus FerriZre & Ilelucchi is found regularly in olive orchards during the fruiting period. In the island of Chalki (near Rhodos) the parasitization rate was found around 20% in January (Stavraki, 1970). In Crete, this eulophid parasite is observed throughout the season but it becomes abundant only from August onward reaching a peak in October.…”

“…For the same reason it is also the main parasitoid of D. oleae on oleasters and the only parasitoid on oleasters on the mountains (Neuenschwander et al, 1983). Although it attacks several other microlepidopterans (Stavraki, 1970), it is almost completely restricted to D. oleae under the conditions of Cretan olive orchards. Among the different larval stages of D. oleae, P. mediterraneus prefers the third stage.…”

Parasitoids for the control of Dacus oleae in Crete¹

In spite of widespread application of poisonous bait sprays against Dacus oleae in Crete, populations of its parasites sometimes show high densities. Most important are the chalcid ectoparasites Eupelmus urozonus and Pnigalio mediterraneus and the braconid Opius concolor. Several efforts for biological control of D. oleae with O. concolor have been made in Greece. The most promising were inundative releases against the spring generation of D. oleae as well as releases within foci of D. oleae in summer. Introduced exotic parasitoids (Biosteres longicaudatus, Dirhinus giffardii and B. oophilus) failed to establish.
