- ... Laboratory and field experiments were performed to determine the efficiency of the entomopathogenic nematode Heterorhabditis bacteriophora against third instar larvae of the tephritid fruit fly Anastrepha ludens. Infection was affected by low (6%) and high (12-24%) soil moisture; the highest prevalence of infection was observed at 9% moisture. LC50 values were estimated under laboratory conditions ...

- ... Laricobius rubidus LeConte, native to eastern North America whose primary host is Pineus strobi Hartig, has been observed in association with Adelges tsugae, an exotic and lethal pest of hemlock trees in eastern North America. Pineus strobi and A. tsugae were used to evaluate host preference and suitability of this predatory beetle to determine in part its suitability as a potential biological con ...
