A molecular procedure incorporating polymerase chain reaction (PCR) of the COI gene and restriction endonuclease digestion of PCR products was used to distinguish Peristenus howardi (Hymenoptera: Braconidae) from four other Peristenus species. Non-solvent extraction of parasite DNA using a commercially available kit proved to be very effective in producing(More)
The parasitoid, Peristenus howardi Shaw (Hymenoptera: Braconidae) has been found to parasitize a large proportion of Lygus species in some Washington and Idaho alfalfa seed fields. During 2002-2003 a survey was conducted to estimate the proportion of Lygus spp. (Hemiptera: Miridae) parasitized and the amountof that parasitism attributable to P. howardi in(More)
A series of experiments was conducted using membrane sachets containing MP148 diet or phosphate-buffered sucrose with and without purified Potato leafroll virus to determine if direct encounter with the virus would arrest the aphid, Myzus persicae (Sulzer) (Homoptera: Aphididae). In only two out of 36 tests were there significantly more aphids settled on(More)
