- ... This study assessed the influence of microenvironment on the establishment and relative reproductive success of the gall-forming midge Rhopalomyia californica Felt on its host plant Baccharis pilularis De Candolle in Marin County, CA. Mesh cages were used to alter the microenvironment, which also allowed us to assess the validity of using these types of experimental manipulations in this system. T ...

The cecidomyiid midge, Rhopalomyia californica Felt, forms galls on the perennial evergreen shrub Baccharis pilularis De Candolle, which is found in coastal regions throughout central California. R. californica, however, is not found in the more southern part of its host's range and is essentially absent south of Santa Barabara. Reasons for this restricted distribution were examined by field exper ...
