ΒΙΟΛΟΓΙΑ ΚΑΙ ΣΥΜΠΕΡΙΦΟΡΑ ΣΤΟ ΕΡΓΑΣΤΗΡΙΟ ΤΟΥ CHAETORELLIA AUSTRALIS HERING (DIPTERA, TEPHRITIDAE), ΕΧΘΡΟΥ ΤΟΥ ΖΙΖΑΝΙΟΥ CENTAUREA SOLSTITIALIS L. (ASTERALES, ASTERACEAE), ΜΕ ΕΜΦΑΣΗ ΣΤΗ ΣΥ...

IT WAS FOUND THAT AT 25 C, THE MEAN LONGEVITY OF FEMALES WAS 33,7 DAYS AND THATOF MALES 49,3 DAYS. MATING BEGAN THE SECOND DAY AFTER EMERGENCE AND OVIPOSITION ONE DAY LATER. FEMALES LAID ON THE AVERAGE 79,1 EGGS AND THE MEAN FERTILITY WAS 90,5%. THE FLY WAS SUCCESSFULLY REARED FOR UP TO 2 GENERATIONS ON AN ARTIFICIAL DIET. SOME BIOLOGICAL DATA OF ADULTS REARED FROM THAT DIET ARE GIVEN. IN THE LABORATORY IT WAS OBSERVED THAT THE FEMALES, IMMEDIATELY AFTER OVIPOSITION, DRAG THEIR OVIPOSITOR ON THE HEAD SURFACE DEPOSITING A WATER-SOLUBLE OVIPOSITION-DETERRING MALE ARRESTING PHEROMONE, PERSISTED ON THE FLOWER HEAD SURFACE FOR AT LEAST 10 DAYS (25 C). IN A NO-CHOICE OVIPOSITION PREFERENCE EXPERIMENT IN WHICH FLOWER HEADS OF 7 CENTAUREA SPECIES WERE COMPARED, THE FEMALES DEPOSITED A GREAT NUMBER OF EGGS IN C. SOLSTITIALIS AND C. CYANUS HEADS, ONLY FEW EGGS IN C.CALCITRAPA AND C. SALONITANA HEADS, AND NO EGGS IN C. MACULOSA, C . MACEDONICAAND C. SOLSTITIALIS HEADS. THE SPINES OF THE HEADS OF THAT PLANT WERE FOUND TOAFFECT OF SHAPE, SIZE AND COLOR ON THE SELECTION FOR OVIPOSITION, ARTIFICIAL OVIPOSITION SUBSTRATES WERE USED. IT WAS FOUND THAT SPHERICAL AND CONICAL OBJECTS WERE PREFERED TO CYLINDRICAL AND CUBICAL ONES. FURTHERMORE, IT WAS FOUND THATSPHERES OF 5 AND 10 MM DIAMETER WERE PREFERED FOR OVIPOSITION TO 15 AND 20 MM ONES. YELLOW AND ORANGE COLORED OBJECTS WERE PREFERED FOR OVIPOSITION TO BLACK,GREEN, BLUE, RED AND WHITE ONES.
