Abstract
Larval surveys in connection with studies of the milky diseases of the Japanese beetle, Popillia japonica, have shown numerous instances of infection among other scarabaeid larvae with organisms at least similar to those causing type-A and type-B milky diseases of the Japanese beetle, described as Bacillus popilliae and B. lentimorbus, respectively. This paper is limited to a presentation of verified records from 8 states and the District of Columbia, of larvae of the genus ? Cyclocephala found in the field infected with an organism similar to type A and designated as atypical type A or (Cyclocephala strain). One instance is cited in which an infestation of C. borealis was controlled by milky disease.
