Gall-forming Cecidomyiidae from Acacias: Can New Parasitoid Assemblages be Predicted? biocontrol agents for these plants, but are parasitised by a diverse range of hymenoptera. As high parasitism levels can disadvantage biological control agents, general criteria are developed to determine if parasitoid composition can be predicted prior to introduction. Agents with low risk of para

The large . galls have been considered to act as physical barriers to protect larvae from ectoparasitoid attack. We observed that . in

Genetic Variation in the Timing of Larval Mortality and Plant Tissue Responses Associated with Tree ance against ., we examined the timing of larval mortality and tissue responses in a number of susceptible and resistant clones of .. We placed a winged adult on a branch in each of 21 clones, and examined the survival of the next generation. Although the number of larvae that settled on buds in aut

Variable Effects of Plant Module Size on Abundance and Performance of Galling Insectsts. Insects in the family Tenthredinidae were recently reviewed and thus omitted from this review. The abundance or performance of approximately half of 53 species examined was positively related to plant module size. However, negative and parabolic relationships were found for all major insect fami

Diversity, Biology, and Nutritional Adaptation of Psyllids and their Galls in Taiwand and compared. In these psyllid galls, different from normal plant tissue, phloem in the vesicular bundles is oriented closer to the larval chamber than the xylem in the enclosed type of galls. The psyllid species . which induce globular galls on the leaves of . var. . were used as a model system f

Trophic Shift in ,,N and ,,C through Galling Arthropod Communities: Estimates from , and , ew estimates of trophic shift in gall communities and compare patterns of trophic shift across studies. We discuss physiological mechanisms that determine the distribution of stable isotopes throughout gall communities and their potential effect on estimates of trophic shift (δ.C and δ.N).
