Abstract: Galling insects are specialist herbivorous that have the ability of manipulating plant tissue to form complex biological structures called galls. Even though different organisms induce galls in plants, insect highest degree structural complexity. The main goal this study was obtain a preliminary systematic record gall morphotypes from Guanacaste Conservation Area Costa Rica and integr...

The present study aimed to increase knowledge about the diversity and factors that determine distribution of galling insects in Parque Nacional do Itatiaia (PNI), Southeast, Brazil. For this, collections were performed April, August November 2015 March 2016. Seventy gall morphotypes found 12 families, 32 genera 61 species host plants. richness galls did not vary with altitude, but increased fam...

Recent field surveys show that galls induced by Daphnephila spp. (Cecidomyiidae) on Machilus spp. (Lauraceae) are common in Taiwan, yet only five species, four leaf-gall inducers and one stem-gall inducer on M. thunbergii, have been named in the past. Here we describe a new species, Daphnephila urnicola sp. nov. Chiang, Yang & Tokuda, inducing urn-shaped galls on leaves of both M. zuihoensis an...

A new species, Dasineura camassiae Gagné (Diptera: Cecidomyiidae), is described, illustrated and compared to some of its congeners from related hosts and western North America. The new species causes flower galls on Camassia (Agavoideae; Asparagaceae) in the Pacific Northwest. Its current known distribution is Oregon and Washington, USA. Larvae develop in spring in flowers of Camassia spp., cau...

Introduction: Plant galls are insect-induced tumor-like growths of plant tissue which nourish and protect developing gall former larvae (1). Gall inducers are typically host specific (2). The morphology of galls produced is unique to each gall former species and reflects the expression of both insect and host plant genomes (3). For each species of gall inducer, gall size at maturity varies wide...
