Genus Proan Haliday (Hymenopter, Braconidae, Aphidiinae), a distinct Aphidiinae parasitoid group have been recorded for the first time from Punjab. Two species namely, Praon pakistanicum Kirkland, 1979 and Proan volucre (Haliday), 1833 are recorded for the first time from arid tract of Punjab Province of Pakistan. Praon pakistanicum Kirkland, 1979 has been redescribed. Both species have been illustrated using micrographs. A tentative key for the identification of these two species has been given.

Key words: Proan, Hymenoptera, Aphidiinae, Punjab, Pakistan.


Genus Proan Haliday comprised of aphid parasitoids having wing venation with recurrent vein developed; interradial vein effaced, notaulices distinct throughout, lateral lobes of mesonotum setose (Raychaudhuri, 1990; Kavallieratos et al., 2001).This group of Aphidiines pupate inside the parasitized aphid in comparison to others (Stary, 1970). Many species of the genus are important as biological control agents in various agro- and forest ecosystems (Rakhshani et al., 2007).


During 2005-2007, adult parasitoids were collected by net sweeping from wheat and pea. The parasitoids were identified through a reliable key (Raychaudhuri, 1990). The illustrations were prepared using a Nikon microphotograph system (Sms-1500, with 30x 1-11.25x magnification). Measurements of taxonomically important parts were taken with the help of stage and ocular micrometer using Noif microscope (XSZ 107BN, with 10X10X magnification).

A lot of work have carried out on the taxonomic studies of these parasitoids in various parts of the world like in North America (Johnson, 1987), South America (Stary and Vogel, 1985, Stary 1995), Europe (Mackauer, 1959; Stary, 1966; Kierych, 1975; Stary 1981; Boness and Stary, 1988), Greek (Kavallieratos et al., 2003) Japan (Takada, 1968), Mediterranea area (Stary, 1976; Stary 1971, 1973; Mescheloff and Rosen (1988),Tremblay and Pennacchio (1985) and Tremblay et al. (1985).

From adjacent countries of Pakistan like Iran (Rakhshani et al., 2007, Barahoei et al., 2010) and India (Raychaudhuri, 1990), but in Pakistan due to lack of basic research on their use as natural bio-control agents only four species of this genus were reviewed by Stary et al. (1998). During 2005-07 various surveys were conducted to explore parasitoid fauna of Punjab Province of Pakistan. Two species of this genus were recorded for the first time from Punjab Province and have been presented along with short taxonomic notes. This work will help the workers in future for identification and better utilization of these biocontrol agents in various integrated pest management programmes.

Material Examined: Observed specimens were collected from Rawalpindi by net sweeping method. Rawalpindi, 29-iii-05, 2 and 1; attock, 30-iii-07, 4 and 2a nd Jehlum , 29-iii-06.

Comments: This species was imported from Peshawar (NWFP) Pakistan in 1977, being reared for biological control of Schizaphis graminum at University of Mis- souri-Columbia and Oklahoma State University, Stillwater. Now during present studies, this species was collected from Rawalpindi (Punjab) and indicated its distribution in Punjab Province of Pakistan also. This species is recorded for the first time from the Punjab province of Pakistan. It indicates distribution of this species in Punjab Province of Pakistan also.
