Aphidius platensisBrethes, its distribution and host range (Hym. : Aphidiidae)

Abstract

The research on the distribution and host range of Aphldius platensls has shown that this species is apparently indigenous to India, being further distributed in Africa, Australia, Middle East, South America, and Nearctic America (Californiaintroduced). Its host range is very wide both as to taxonomic affinities and ecology of its hosts. which all belong to the Aphididae. Its utilization as II possibly useful biological control agent is promising.Research on aphid parasites of the tropics and allied zones of South America. Africa and Australia has shown that the parasite spectrum of tbe main pest aphids (mostly cosmopolitan and I or pantropical species) is remarkably poor and consisting of widely specialized and distributed species, such as Diaereliel/a rapae. Ephedrus persicae, Aphidius platensfs. etc.Our attention has been paid to Aphidius platensis. which was known to occur in South America and Australia. apparently a species of Neotropical origin. It is the aim of this small contribution to explain its origin and distribution, host range. and specific features of possible utilization in aphid control. Aphidius platcnsis nr~thcs

Survey of the Aphid Parasitoids (Hymenoptera: Braconidae: Aphidiinae) of Costa Rica with Information on Their Aphid (Hemiptera: Aphidoidea): Plant Associations

“…Aphidius colemani occurs in warmer regions around the world and is common in South America, but presumably originated in the Oriental region [17]. Based on host records from Venezuela [10], Chile [13], and Brazil [11], it is probable that this species attacks a greater range of aphids in Costa Rica than that reported here.…”

The parasitoid complex [Hym.: Ichneumonoidea] ofToxoptera aurantii [Hom.: Aphidoidea] in the Mediterranean area

“…), in spite of its wide distribution in the Mediterranean region (see Star), 1975), seems to be restricted to Near East as T aurantii endoparasitoid, i.e. in Israel and Lebanon (Rosen, 1969 ;present data).…”

“…) and Lysiphlebus fabarum (Marshall) were quoted as playing a dominant rble in several areas (Star~, 1964 ;Rosen, 1969). In 1973-74 the nearctic parasitoid Lysiphlebus testaceipes (Cresson) was introduced in the Mediterranean France and in Corsica (Star~ et al, 1975 ;Star~, 1976). In 1977-78 this species was discovered in the citrus groves of Central and South Italy, including Sicily (Tremblay et al, 1978 ;Tremblay & Barbagallo, 1983).…”

Inter-specific variation in the reactive distance of different aphid-parasitoid associations: analysis from automatic tracking of the walking path

“…They were chosen because they are known to show different levels of specificity with the three aphid species tested (Starý, 1974(Starý, , 1975Messing and Rabasse, 1995 gossypii. This choice also allowed a comparison between two main groups of aphid parasitoids, the genus Aphelinus and the genus Aphidius (sub-family Aphidiinae).…”
