Poplar Tree Response to Feeding by the Petiole Gall Aphid Pemphigus spyrothecae Pass

open access: yesInsects, 2020
Pemphigus spyrothecae Pass. which is a member of the subfamily Pemphiginae is one of the gall-inducing aphids that occurs on poplar trees. Phloem feeding of a founding mother on leaf petiole results in the formation of a new organ, i.e., the spiral gall.

Characterization of entomogenic galls in areas of seasonal deciduous forest in Southwestern Bahia, Brazil

open access: yesEntomoBrasilis, 2023
Galls are small structures induced mostly by insects in different plant organs, and have different shapes and colorations. Knowledge on galls is still sparse in the semiarid region of Bahia. Therefore, the goal of this study was to characterize galls in

Regulation and Functions of Long Noncoding RNAs During Meloidogyne incognita Parasitism of Tomato

open access: yesMolecular Plant-Microbe Interactions
Long noncoding RNAs (lncRNAs) are emerging as important regulators of various aspects of immune response and plant-pathogen interactions. However, the regulatory function of lncRNAs during plant-nematode interaction remains largely elusive. In this study,

List of plants with galls induced by insects from the UNILAVRAS/Boqueirão Biological Reserve, Ingaí, state of Minas Gerais, Brazil [PDF]

open access: yesCheck List, 2012
Tumors caused on vegetal tissues, named galls or cecidiens, may occur due to the action of several organisms such as bacteria, viruses, nematodes, fungi and insects. The main inductors are insects and this is a highly complex kind of herbivory.

The spatial distribution of leaf galls of Mikiola fagi (Diptera: Cecidomyiidae) and Neuroterus quercusbaccarum (Hymenoptera: Cynipidae) in the canopy of a Central European mixed forest

open access: yesEuropean Journal of Entomology, 2002
Despite their wide distribution and frequent occurrence, the spatial distribution patterns of the well-known gall-inducing insects Mikiola fagi (Hartig) and Neuroterus quercusbaccarum (L.) in the canopies of mature trees are poorly described. We made use
