The so-called blue alfalfa aphid (BAA), Acyrthosiphon kondoi Shinji and Kondo, was first found in North America in 1974. It is far more damaging to alfalfa than the pea aphid, A. pisum (Harris) but is easily killed with chemicals used on alfalfa for

The fecundity, longevity and diapause of Peristenus stygicus Loan was studied. P. stygicus parasitizes the 1st to 4th instars of Lygus hesperus Knight. The number of parasite offspring decreased with an increase in host instar. However, the percent f

Glyptoscelis squamulata, often called the grape bud beetle (GBB), is indigenous to North America. During the 1920’s and into the late 1940’s this univoltine species was considered the major pest of fresh table grapes in the Coachella Valley of so

Peristenus stygicus Loan, a parasite of Lygus , was released in an alfalfa hay field near Bakersfield, Calif., in 1973. The program was evaluated by dissecting a large number of 3rd to 5th instar Lygus (primarily L. hesperus Knight) to determine perc
