First record of Scuttle fly, Megaselia (M) scalaris (Loew) (Diptera: Phoridae) as a parasitoid of Sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae) from Iran

Abstract The Scuttle fly, Eurygaster integriceps Puton (Hemiptera: Scutelleridae) is a key pest of wheat and barley. univoltine migrates from fields following harvest to high elevations; then, the spring it moves back fields. Natural enemies may have an important role in decreasing population’s level overwintering sites. In present study, adults E. were collected sites Isfahan province, Iran, October 2022 transferred laboratory. One week after sampling, dead isolated divided into three groups: one group was dissected under stereomicroscope, parasitoid larvae extracted cadavers; second incubated Petri dishes sealed with parafilm, individually for four weeks, emerged pupae collected; third closed boxes, flies fixing identification. Assessment adult stereomicroscope revealed that insect parasitized Megaselia scalaris (Loew) (Diptera: Phoridae) larvae. Per adult, up 13 found inside . last instar pupated outside body. This study new record M. as intergriceps Iran.
