AbstractThe susceptibility of overwintering black vine weevil larvae Otiorhynchus sulcatus to a cold-active entomopathogenic nematode, Steinernema kraussei (isolate L137) and a commercial proprietary biopesticide, Steinernema carpocapsae (Exhibit) was assessed on outdoor potted strawberry plants. Nematodes were applied at a range of doses in early winter at a field site located in Warwickshire, England. Three months later, infestation and mortality of vine weevils were assessed. There was a clear dose response observed for S. kraussei applications. Up to 81% of vine weevil control was recorded by this nematode at the highest dose of 60 000 nematodes per pot, whereas treatments with S. carpocapsae caused no significant mortality at the dose rates used. Dissection of vine weevil larvae showed infective juveniles had developed to adults within the host. Recovery of nematodes at the end of the experiment indicated that S. kraussei (L137) was able to survive winter field conditions including prolonged exposure to low temperatures (averaging 2.7°C during the experiment) in contrast to S. carpocapsae which showed poor survival. Of the two extraction methods used, the Baermann funnel technique was found to be more efficient than Galleria mellonella baiting, with up to 44% of the original highest dose of S. kraussei nematodes being recovered by Baermann funnel compared to 8% with G. mellonella at 18°C. These results suggest S. kraussei (L137) has potential as a commercial biocontrol agent against O. sulcatus at low temperatures.

Abstract Acoustic detection systems have been developed to locate and target hidden infestations of root weevil larvae in container-grown nursery crops. Tests were conducted in laboratory and field environments with natural and artificial infestations of Otiorhynchus sulcatus (Fabricius) in containers with different nursery plants to determine whether the larvae were large enough for acoustic detection during late fall when scouting for infestation often occurs at commercial nurseries in Oregon. The rootballs of tested plants were examined to verify the presence or absence of larvae. All of the containers rated at high likelihood of infestation contained O. sulcatus larvae (29% of those tested). No larvae were found in any containers rated at low likelihood of infestation (20%). Sporadic sounds were detected but failed to exhibit periodicity suggestive of infestation in 51% of the containers (rated at medium likelihood). Fifty seven percent of these medium-rated containers were infested. Experience with the use of the acoustic system in field environments suggested improvements in user-friendliness and robustness that could improve its utility for early detection and targeting applications in commercial nurseries.
