- 論文の詳細を見る
The formation of the "cat's-paw" gall on Styrax japonica by Ceratovacuna nekoashi is described. The 1st-instar fundatrix attacks an axillary bud (not a terminal bud) of a shoot and the attacked bud soon sprouts to form a cat's-paw. First-instar fundatrices often fight each other for an incipient gall ; this fighting behavior is also described. Daily mapping of buds and galls on shoots showed that only newly-formed axillary buds are available for gall formation. It is suggested that the fighting between fundatrices is the result of competition for these ephemeral resources.
