Other claims from this paper (11)

Observation Native L. rubidus was present in the insectary area.
Observation L. nigrinus populations increased annually.
Observation L. rubidus populations increased annually.
Method / resource The insectary produced 305 F3 L. nigrinus adults collected and redistributed in 2007.
Observation Adult L. nigrinus were active on hemlock from fall to mid-spring, overlapping suitable adelgid stages.
Observation Adult L. rubidus were active on hemlock from fall to mid-spring, overlapping suitable adelgid stages.
Observation L. nigrinus eggs and larvae occurred from late winter to mid-spring on progredientes eggs, synchronously with prey.
Observation L. rubidus eggs and larvae occurred synchronously with suitable prey stages.
Intervention effect Predator exposure lowered adelgid survival and ovisac density relative to cage protection.
Intervention effect Predator exposure increased adelgid ovisac disturbance relative to cage protection.
Recommendation The authors regard L. nigrinus as an important potential biological control agent for hemlock woolly adelgid.
