2 NEW PATHOGENS OF DIPTERAN INSECTS

Two new entomophthoralean fungi pathogenic on dipteran insects were re corded in China. Pandora shaanxiensis was found on blue bottle flies i n Shaanxi, Northwestern China. Its primary conidia are obovoid, symmet ric, 30.3-43.2 x 12.5-19.8 mu m (averaging 32.7 x 15.0 mu m), L/D = 1. 7-3.2 (averaging 2.4). Cystidia are 2 times the thickness of conidioph ores, and rhizoids end in a discoid holdfast. Erynia chironomis was fo und in an epizootic of chironomid midges in Anhui, Eastern China. Its primary conidia are narrow, obovoid, usually asymmetric and sometimes curved, the largest diameter in the apical half, 29.260.6 x 10.4-21.9 mu m (averaging 41.1-48.0 x 13.5-17.1 mm), L/D = 2.1-4.3 (averaging 2. 5-3.6). Cystidia are 203 time the thickness of conidiophores. Rhizoids are 2 times the thickness of conidiophores and do not terminate in te rminal discoidal holdfasts.
