Diversity, Biology, and Nutritional Adaptation of Psyllids and their Galls in Taiwan. In Taiwan, a revision and some supplemental works of psyllid taxonomy were done in the 1980s. In these publications, 18 species of psyllids were noted as being gall formers. Our survey, as of 1996 found a total of 98 types/species of psyllid galls, and many of them are new species/records. The hos

Trophic Shift in ,,N and ,,C through Galling Arthropod Communities: Estimates from , and , between hosts, herbivores, and natural enemies. While the utilization of stable isotope ratios can help to elucidate complex trophic interactions in such communities, estimates of trophic shift between community members are required before stable isotope analyses can be appropriately employed.

Three of 14 gall sorts were dominant in both years (common gall wasps), and 3 dominated in only one of the years (opportunistic gall wasps). Species composition reflect

Cynipid Gall Wasps in Declining Black Oak in New York: Relationships with Prior Tree History and Croincluded swollen twigs, gnarled branches, fungal cankers, and crown dieback. A study conducted from 1994 to 1996 showed that symptoms occurred on trees in urban and forested areas. Trees with greater incremental diameter growth before the gall wasp outbreak suffered less dieback than those that grew
