Photosynthetic efficiency of Clusia arrudae leaf tissue with and without Cecidomyiidae galls

Leaf galls induced by a still undescribed new species of Cecidomyiidae (Diptera) are frequent on leaves of Clusia arrudae Planchon & Tirana (Clusiaceae) in the rupestrian fields at 1400 m a.s.l. in Serra do Cipó, Minas Gerais, Brazil. Galls were 7.1 ± 0.7 mm in diameter, one chambered with only...

Description
Summary:Leaf galls induced by a still undescribed new species of Cecidomyiidae (Diptera) are frequent on leaves of Clusia arrudae Planchon & Tirana (Clusiaceae) in the rupestrian fields at 1400 m a.s.l. in Serra do Cipó, Minas Gerais, Brazil. Galls were 7.1 ± 0.7 mm in diameter, one chambered with only one larva inside. Gall tissue is green and soft. Assessments of photosynthetic capacity using chlorophyll-a fluorescence measurements revealed that photosynthetic performance of gall tissue and healthy leaf tissue were rather similar. Hence, the morphological changes due to gall development were not associated with significant changes in the photosynthetic capacity of the tissue.
