Abstract:
Peachtree borers, Synanthedon exitiosa, in 10 cherry laurel shrubs growing in a landscape setting were treated with the nematode, Steinernema carpocapsae (strain All). Ten infested cherry laurel were controls in the trial. Nematodes were applied in April using a backpack sprayer. Applications of entomopathic nematodes significantly reduced (66%) the number of living larvae associated with the plants.

Abstract:
The peachtree borer, Synanthedon exitiosa, and lesser peachtree borer, S. pictipes, are economically important indirect pests of peach in West Virginia. The purpose of this 3-year study was to compare the efficacy of mating disruption and post-harvest trunk sprays of chlorpyrifos insecticide for control of this pest complex in a commercial peach orchard. Overall, Isomate PTB-Dual disruption dispensers applied at a rate of 371/ha significantly disrupted the male mate-finding behavior of S. exitiosa and S. pictipes. In addition, the infestation of peach trees by S. exitiosa larvae did not vary significantly between mating disruption and insecticide treated plots. Hot-spot maps of S. exitiosa infestation showed significant spatial clusters of infestation predominately near the perimeter of all orchard plots, or where trees were missing within and/or between rows. The generation of standard deviational ellipses revelated that the location of S. exitiosa infestations in orchard plots remained relatively constant between years, and were generally oriented in a north and easterly direction, which coincided with the prevailing wind direction. Although our data indicated that mating disruption can provide growers with an effective non-chemical alternative to chlorpyrifos trunk sprays, several variables may affect its long-term success in West Virginia peach orchards; most notably the presence of high population densities, problems with maintaining adequate pheromone coverage, and the need for area-wide implementation.

Abstract:
Abstract Adult males and larvae of sesiids were monitored in ten (1989–1991), five (2000) and two (2004) Quebec apple orchards. Multi Pher III traps baited with 99.1% Z, Z-3, 13-octadecadienyl acetate and 0.9% Z, E plus E, Z-3, 13-octadecadienyl acetate were used for adults, and trunk sampling was used for larvae. Synanthedon scitula, S. pyri, Podosesia syringae, S. acerrubri, S. fulvipes, S. exitiosa, S. acerni and Sesia tibialis males were captured between 1989 and 1991. Only 5 of the 347 adults of the S. scitula/pyri complex captured in 2000 belonged to S. pyri.

Abstract:
The peachtree borer, Synanthedon exitiosa (Say) (Lepidoptera: Sesiidae), is a major pest of stone fruits including the peach Prunus persica (L.) Batsch. The entomopathogenic nematode, Steinernema carpocapsae, was previously shown to be an effective tool for controlling S. exitiosa. In orchards where irrigation is not available, a sprayable gel (Barricade®) can be used to maintain soil moisture which can facilitate nematode efficacy. However, rates of nematode and Barricade® application had not been optimized for their maximum economic and biocontrol efficiency. Therefore, our objective was to compare rates of S. carpocapsae and Barricade® in field trials. Nematodes were tested at per-tree application rates of 1.5 million, 1 million and 0.5 million infective juveniles. The sprayable gel was used at two rates, 4% and 2%. A reduction in the used nematodes from 1.5 million to 0.5 million per tree showed no difference in efficacy. Similarly, using the gel at half rate also did not impact the efficacy, and treatments containing nematodes controlled the S. exitiosa better than the chlorpyrifos control in several of the tests (p < 0.05). As an added benefit, the nematode treatments were also able to reduce the prevalence of weevil (Coleoptera: Curculionidae) populations as secondary pests of the peach trees. The lower rates of grower inputs will reduce costs, making the nematode biocontrol of the peachtree borer more likely to be adopted by commercial growers of peach.

Abstract:
Abstract Prunus cistina growing in 2-gal containers and infested with Synanthedon exitiosa were planted in a research plot at the Ohio State University Agricultural Research and Development Center in early June, prior to moth emergence. These plants were used for evaluating efficacy of selected insecticides for reducing establishment of peachtree borer larvae. A COz compression sprayer with a Teejet SS8004 flat-fan nozzle operating at 16 psi was used to spray four 4-plant replicates/treatment arranged in a randomized complete block design. Sprays were applied 14 Jun under sunny skies at 18�C with a breeze of 8-16 km/h. Each plant received 70 ml of finished spray on its lower trunk and limbs. Treatment effectiveness was evaluated 6 Sep by examining the base of each plant for exudate and frass.

Abstract:
The peachtree borer, Svnanthedon exitiosa (Say), (Sesiidae), was studied to determine factors influencing its distribution, and four possible methods for its control in Prunus orchards in the Okanagan Valley, B.C. A survey for peachtree borer infestation was made by inspecting more than 7000 Prunus trees in 49 orchards, and 34 chokecherry trees, Prunus virginiana L., the native host, at 9 sites. Seventy-five per cent of the Prunus plantings contained peachtree borer. Infestation levels ranged from 0.9-83.3 % of the trees per planting. Young trees were least often attacked. Peach was the most heavily attacked species, prunes and apricots were intermediate, and cherry was the least attacked. Differences in bark texture appeared to be an important factor influencing oviposition behaviour and larval survival and establishment. Trees in clay soil without vegetation around the trunk were more heavily infested than trees in loam or in clay with vegetation. No peachtree borers were found in any of the chokecherry trees examined nor in any abandoned Prunus plantings. Fertilization and irrigation were important in determining borer survival and establishment. More than half of the forty growers surveyed did not know if their orchards were infested with peachtree borer, although all mature plantings where no controls were being carried out contained borers. Four possible control methods were tested in five infested orchards. Two methods, removal of borer larvae by hand and coating the trunk with rubber latex in an attempt to prevent larval entry, were ineffective. Chemical control was more successful but 20 % of the trees sprayed once with endosulfan (Thiodan) at the beginning of the period of adult emergence were successfully attacked during the summer. This was reduced to 7.8 % on trees that received a second spray 4 weeks later. An aluminum cone designed to protect the basal area of the tree trunk that is most susceptible to borer attack was completely successful in preventing infestation. These results are compared with the results of growers' control programs. Conventional endosulfan trunk sprays are very effective when properly applied, but only 5 of 40 growers were using them. The advantages and disadvantages of all methods of control are discussed and the importance of growers' understanding the biology of the insect and compatibility of control methods within the context of the total orchard operation emphasized.<br>Land and Food Systems, Faculty of<br>Graduate
