Abstract :
During the investigations which were done to find Myzus persicae (Sulzer, 1776) and Trioxys pallidus (Kaltenbach, 1843) parasitoid for one year (2018-2019) in Markazi province. Sampling of the parasitized aphids by direct observation method was collected from different plants ( fruit trees, greenhouse crops (pepper and cucumber) and weeds) and transferred to the laboratory. The parasitic aphids, along with the host plant and a damp cotton, were then placed in containers with small net nets that the insects could not pass through. The ambient temperature was set at 25 ° C for them. After a few days, some mummified aphids of parasitoid bees were hatched from inside the body and some other hyperparasitoid wasps were hatched from inside the body. These parasitoid and hyperparasitoid wasps were collected and placed in 75% alcohol and then Identify. A parasitoid wasp collected from M. persicae under the species Aphidius platensis Brethes, 1913 (Hymenoptera: Braconidae), a hyperparasitoid collected from this parasitoid also called Pachyneuron aphidis (Bouché, 1834) (Hymenoptera) The parasitoid wasp that emerged from the mummified aphids Chromaphis Juglandicola was also identified as Trioxys pallidus (Haliday, 1833) (Hymenoptera: Braconidae). All three species are reported for the first time from Markazi province. A. platensis can be a good alternative to imported wasps in biological control against aphids in greenhouses.
