| Abstract | The originally Australian coccidophagous predatorRhyzobius forestieri (Coleoptera: Coccinellidae), imported from California into Greece in 1981, was first released on citrus at Cambos, Chios, in 1983 against soft scalesCoccus pseudomagnoliarum andSaissetia 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 ofR. 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.Le prédateur coccidiphageRhyzobius forestieri (Coleoptera : Coccinellidae) d’origine australienne, importé en Grèce de Californie en 1981, a été pour la première fois lâché sur agrumes contreCoccus pseudomagnoliarum etSaissetia oleae (Homoptera : Coccidae) dans la région de Cambos à Chios en 1983.Au cours de la décennie suivante,R. forestieri s’est dispersé spontanément dans toute la plaine littorale de Cambos. En juillet 1992, un inventaire des coccinelles coccidiphages a été fait pour suivre la dispersion deR. forestieri sur agrumes et pour comparer l’importance de sa population à celle des coccinelles coccidiphages indigènes les plus importantes.Des échantillonnages ont été faits sur 4 vergers d’agrumes à une distance de 1–2 km l’un de l’autre dans la region de Cambos, choisis pour leur infestation par les cochenilles. Sur un total de 337 adultes et de 237 larves de coccinelles coccidiphages trouvées,R. forestieri représente respectivement un pourcentage de 84.0 % et 75.1 %. Sa présence a été notée dans les 4 localités ; dans 2 d’entre elles, adultes et larves deR. forestrieri sont les coccinelles prédominantes. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
