Joella C. Killian, Professor of Biology, earned a Ph.D. (1984) in entomology from North Carolina State University and an M.A. (1980) in biology from the University of North Carolina at Greensboro, after having received a B.A. (1976) in zoology from the University of North Carolina at Chapel Hill. A member of the Entomological Society of America and the scientific research society Sigma Xi, Dr. Killian is an expert in tree fruit entomology.
Dr. Killian's research activities have centered in recent years on mating disruption research in orchards and vineyards in Virginia. Insects studied in this regard are codling moth, leafrollers and dogwood borer in apple, oriental fruit moth and lesser peachtree borer in peach, and grape berry moth in grape. Earlier projects involved effects on ground cover management in peach orchards on catfacing injury at harvest. Other interests include monitoring of water quality in the Rappahannock River.

ABSTRACT: The responses of tufted apple bud moth, Platynota idaeusalis (Walker), the leafroller P. flavedana Clemens, redbanded leafroller, Argyrotaenia velutinana (Walker), and obliquebanded leafroller, Choristoneura rosaceana (Harris), to the pheromone blends of each, as well as to 3 putative generic blends (two- and three-component blends containing pheromone elements of each of the 4 species) were evaluated in small orchard plots.
ABSTRACT: White apple leafhopper, Typhlocyba pomaria McAtee, and potato leafhopper, Empoasca fabae (Harris), were evaluated for their potential to incite fire blight infection in apple in the presence of the causal organism, Erwinia amylovora (Burrill) Winslow et at. Each leaf hopper species was used as one factor in a series of 2 x 2 factorial experiments; the other factor was the presence or absence of E, amylovora. There was no evidence for a role for white apple leafhopper which feeds in the mesophyll of middle-aged and older leaves. There was sometimes a significant role for potato leafhopper which feeds in the vascular tissue of growing shoot tips.
ABSTRACT: Polyethylene dispensers (Shin Etsu) containing 172 ml of the sex pheromone, (E,E)-8–10-dodecadien-1-ol (63%), dodecenol (31%) and tetradecenol (6%), of codling moth (CM), Cydia pomonella (L.), were placed in apple orchards in Virginia. Two blocks of about 2 ha each were treated in 1989, and three in 1990. Dispensers were placed in trees at a density of 1000/ha shortly after apple bloom. Male orientation to pheromone traps was almost totally disrupted (a few males were captured at high population densities).
ABSTRACT: Dispensers (20·cm polyethylene capillary tubing; "ropes") containing Oriental fruit moth pheromone were placed in a 4-hl\ block of peaches shortly before first male night. This placement of ropes disrupted attraction to conventional pheromone traps for the duration of the season.
