because Atkinson (1983) found that adult R. lophanthae had an LD50 at about 420C.

Stathas (2000) found that in Greece R. lophanthae completed 6 generations a year, while

Smirnoff (1950) speculated that they may be able to complete as many as 7-8 generations

a year in Morocco.

 This particular coccinellid was mentioned by Howard (1997) as a possible

biological control of CAS; but never mentioned again. Rhyzobius lophanthae has also

been labeled as "highly effective" in controlling CAS in Hawaii (Hara et al. 2004).

However, there are no research data to support this claim. In Tampa, Florida, adults and

larvae have been seen in large numbers feeding on CAS (personal observation 2004).

The fact that this beetle is already found in Florida makes it an appealing candidate for

the biological control of CAS. Label data with specimens in the FSCA indicate this

predator was captured feeding on Fiorinia theae Green, P. cockerelli, Pseudaulacaspis

pentagon (Targioni-Tozzetti), and Acutaspis morrisonorum Kosztarab.
