Post-release establishment and supercooling point assessment of Laricobius osakensis, a predator of the hemlock woolly adelgid
… are adelgid specialists. In 2005, Laricobius osakensis, was discovered in Japan and in 2010 was approved for release in the eastern United States and there have now been more than 60 releases. In 2014, the polar vortex resulted in significant HWA mortality in the eastern U.S., depleting the …

Pre-release Evaluation of Laricobius osakensis Montgomery and Shiyake (Coleoptera: Derodontidae), a Potential Biological Control Agent for the Hemlock Woolly Adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), in the Eastern United States
… in the eastern US. A new predator, Laricobius osakensis Montgomery and Shiyake, has been found in association with A. tsugae in Japan. Laricobius osakensis was evaluated in a series of pre-release studies to assess its potential as a biological control agent for A. tsugae. Host-range studies …

Assessing performance and compatibility of three Laricobius species as predators of hemlock woolly adelgid, Adelges tsugae
… nigrinus Fender, L. rubidus, LeConte, and L. osakensis Montgomery and Shiyaki (proposed), predators of hemlock woolly adelgid, Adelges tsugae, Annand, were investigated in the laboratory and in the field. In individual assays, L. rubidus oviposited fewer eggs than either L. nigrinus or L. …

Evaluation of hybridization among three Laricobius species, predators of hemlock woolly adelgid, (Adelgidae)
… studies, there was no evidence that Laricobius osakensis Montgomery and Yu could produce hybrid progeny with either Laricobius nigrinus Fender or Laricobius rubidus LeConte. Interaction between L. osakensis and L. nigrinus did not result in a lower production of progeny as a result of fitness …

Laboratory rearing, establishment, subterranean survivorship, and thermal requirements of Laricobius spp. (Coleoptera: Derodontidae), biological control agents released for Adelges tsugae (Hemiptera: Adelgidae)
… Fender (Coleoptera: Derodontidae) and Laricobius osakensis Montgomery and Shiyake (Coleoptera: Derodontidae) have been evaluated, approved, and released. The production and subsequent release of these agents has largely occurred through mass rearing efforts by Virginia Tech. A descriptive analysis …

Release-Recovery in the Field and Reproductive Success in the Lab of Laricobius osakensis (Coleopera: Derodontidae) a Biological Control Agent for the Hemlock Woolly Adelgid, Adelges tsugae
… States. One biological control agent, Laricobius osakensis, shows promise due to its voracious feeding on and synchronous life cycle with HWA. This beetle species is originally from Japan and has undergone all the necessary testing while in quarantine, gaining permission for field release in 2010. …
