Sy. Yang et al., Preliminary notes on the three Cecidomyiidae (Diptera) galls on Machilus thunbergii Hayata (Lauraceae) in the Guandaushi forest of central Taiwan, BOTAN B A S, 40(2), 1999, pp. 153-158
Three cecidomyiid galls were found on Machilus thunbergii Hayata (Lauraceae
) in the Guandaushi forest of central Taiwan. The one on the twigs is the s
pindle-shaped gall. The two on the leaves are the swan-shaped gall and the
club-shaped gall. These galls are all induced by gall midges of the genus D
aphnephila (Diptera: Cecidomyiidae). Galls, the larvae of the inducers, gal
l size, and the general structures of the gall were studied and are describ
ed in this paper.
