Status and importance of Rhyzobius forestieri (Col.: Coccinellidae) on citrus at Chios Island, Greece, nine years after its introduction
Entomophaga 42 (3), 387-392
Abstract: The originally Australian coccidophagous predator Rbyzobius forestieri (Coleoptera: Coccinellidae), imported from California into Greece in 1981, was first released on citrus at Cambos, Chios, in 1983 against soft scales Coccus pseudomagnoliarum and Saissetia oleae (Homoptera: Coccidae). It was successfully established in two orchards there.
During the following decade, R. forestieri spontaneously dispersed throughout the Cambos coastal plain. In July 1992, a survey of coccidophagous coccinellids was carried out, to follow up on the dispersal of R. forestieri, on citrus and to compare its population size with that of the main native coccidophagous coccinellids.
The samplings were made in 4 selected scale-infested orchards of Cambos spaced 1-2 km apart. Of a total of 337 adults and 237 larvae of coccidophagous coccinellids found, R. forestieri comprised 84.0% and 75.1%, respectively. It was present in all 4 localities; in 2, R, forestieri adults and larvae were by far the most abundant coccidophagous coccinellids.
