Abstract
Anagyrus indicus Shafeeet al. was collected on the island of Guam and released in the Jordan River Valley of Jordan in order to regulateNipaecoccus viridis (Newstead) on citrus.A. indicus was originally released in February 1984 and became colonized by April of the same year. It also dispersed by natural means up to 61 km following the original release and colonized that same year on infestedZizyphus sp. By spring of 1985 it became the dominant parasitoid attackingN. viridis. Another parasitoid,Anagyrus kamali Moursi, was collected in Jordan in June of 1985 for the first time. This latter parasitoid apparently moved into the Jordan River Valley by means of natural dispersal from a neighboring country. Infestations ofN. viridis have been greatly reduced in areas whereA. indicus became established.
Résumé
Anagyrus indicus Shafeeet al. a été récolté à l'île de Guam et lâché dans la vallée du Jourdain en Jordanie afin de réduire les populations deNipaecoccus viridis (Newstead) sur citrus. A l'origineA. indicus fut lâché en février 1984 et s'implanta en avril de la même année. Il se dispersa aussi naturellement à plus de 61 kms du point de lâcher d'origine et s'établit la même année sur lesZizyphus infestés. Au printemps 1985, il devint le parasitoid dominant attaquantN. viridis. Un autre parasitoid,Anagyrus kamali Moursi, a été récolté en Jordanie en juin 1985 pour la 1re fois. Ce dernier parasitoïde arrivait apparemment d'une région voisine dans la vallée du Jourdain par les moyens naturels de dispersion. Les infestations dues àN. viridis ont été fortement réduites là oùA. indicus s'est établi.
