PARASITISM OF THE TARNISHED PLANT BUG, LYGUS LINEOLARIS (HEMIPTERA: MIRIDAE), BY PERISTENUS PALLIPES AND P. PSEUDOPALLIPES (HYMENOPTERA: BRACONIDAE)

Abstract

Can. En?. 108: 601-608 (1976) Life cycles of Perisrenus pallipes (Curtis) and P . pseudopallipes (Loan), parasitoids of the tarnished plant bug, Lygus lineolaris (P. de B . ) , were investigated in an alfalfa field and in uncut weeds in the Ste. Anne de Bellevue area. In 1972, P . pallipes adults emerged in mid-May and P . pseudopallipes adults emerged in late July. The incidence of parasitism in nymphal and adult stages of the tarnished plant bug, L. lineolaris, was measured. The population of the tarnished plant bug in the weeds was more heavily parasitized than the one in the alfalfa field. The ichneumonid hyperparasite Mesochorus curvulus Thomson was also found in this area.

Review of the Nearctic species of Leiophron and Peristenus (Hymenoptera: Braconidae: Euphorinae) parasitizing Lygus (Hemiptera: Miridae: Mirini)

“…Loan (1965) described the biology of this species under P. pallipes associated with Lygus lineolaris. Lim et al (1976) and our data confirm Loan's biological observations.…”

“…cause significant economic damage to stems, leaves, fruits and seeds of a wide variety of crops in North America. Intensive research in Canada and the United States on Lygus bug endoparasitoids showed that euphorine braconid wasps play a role in their control (Ashfaq et al 2004;Braun et al 2001;Broadbent et al1999;Carigan et al 1995;Day 1996Day , 1999Day et al 1990Day et al , 1992Day et al , 1996Day et al , 1998Day et al , 1999Day et al , 2000Day et al , 2003Haye et al 2005Haye et al , 2006Lachance et al 2001;Lim et al 1976;Loan 1965Loan , 1970Loan , 1974aLoan , 1980Loan et al 1976Loan et al , 1987Picket et al 1998Picket et al , 2000Picket et al , 2001Picket et al , 2002Picket et al , 2003Picket et al , 2005Tillmon et al 2000). The endoparasitoids belong to species of Leiophron and Peristenus.…”

Detection of EuropeanPeristenus digoneutisloan in mirid populations in southern Ontario

“…Lygus lineolaris Palisot de Beauvois (Hemiptera: Miridae) is parasitised by four native parasitoids (Hymenoptera: Braconidae) in eastern Canada (Loan 1970;Lim and Stewart 1976;Broadbent, Goulet, Whistlecraft, Lachance, and Mason 1999; Biocontrol Science and Technology, Vol. 18, No.…”

“…6, 2008, 583Á590 Sears, Goulet and Mason 2006). Two species, P. mellipes Cresson and P. pseudopallipes Loan, are univoltine and attack Lygus nymphs in the spring and summer, respectively (Lim and Stewart 1976;Goulet and Mason 2006). These species are North American members of the Peristenus pallipes complex, a complex of difficult to distinguish species of Holarctic distribution and are members of the Peristenus mellipies subgroup described in the taxonomic revisions of Goulet and Mason (2006).…”

“…These native parasitoids do not suppress Lygus plant bug populations in economically important agricultural crops in Canada. This may be due to the fact that these parasitoids prefer habitats that contain a mixture of flowering weeds rather than agricultural crops (Streams, Shahjahan, and Le Masurier 1968;Shahjahan 1974;Lim and Stewart 1976;Loan 1980;Broadbent et al 2006). In Europe, Peristenus species cause high levels of parasitism in crop habitats such as red clover and alfalfa (Haye, Kuhlmann, Goulet, and Mason 2005;Gariepy, Kuhlmann, Gillott, and Erlandson 2008a).…”
