Diversity of galling arthropods and host plants in a subtropical forest of Porto Alegre, southern Brazil

open access: yes, 2006
Many hypotheses have been proposed to explain diversity patterns of galling insects. However, there are contradictory evidences on the evolutionary and ecological factors responsible for the trends.

Larval character evolution in Holometabola (Insecta)

open access: yesCladistics, EarlyView.
Abstract Larvae, a novel type of immature stage, are a crucial innovation of the Holometabola. Larval features therefore provide key evidence for reconstructing evolutionary transformations in this megadiverse group. Here we present the first formal reconstruction of larval character evolution, using maximum parsimony and Bayesian ancestral‐state ...

Pest‐preservation paradox among insects

open access: yesConservation Biology, EarlyView.
The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

Forest thinning creates short‐term roosting opportunities for northern long‐eared bats in central hardwood forests

open access: yesConservation Science and Practice, EarlyView.
Reconciling timber production with the habitat requirements of forest‐dependent wildlife is a challenge for biodiversity conservation. In managed Central Hardwood Forests of the United States, female northern long‐eared bats (Myotis septentrionalis) selected tree roosts near ridgetops and management features, including recently created regeneration ...

Insect galls of Restinga de Marambaia (Barra de Guaratiba, Rio de Janeiro, RJ)

open access: yesBrazilian Journal of Biology
Thirty-one morphotypes of insect galls and two flower damages were found on 16 families, 22 genera and 24 plant species in Restinga de Marambaia (Barra de Guaratiba, Rio de Janeiro, RJ).

Gall-forming insect attack patterns: a test of the Plant Vigor and the Resource Concentration Hypotheses [PDF]

open access: yesBiotemas, 2013
We tested the following two hypotheses to investigate the attack patterns by gall-inducing insects on their host plant Eriotheca pubescens: (i) vigorous modules are more often attacked by galling insects; and (ii) E.

Gall induction by hemipteroid insects

open access: yesJournal of Plant Interactions, 2011
The Thysanoptera and sternorrhynchous Hemiptera induce galls through feeding action, a behavior similar to that in the Cecidomyiidae. Salivary glands of gall-founding female thrips include greater quantities of hydrolyzing enzymes and soluble proteins than those in either males or pupae, which possibly alter the host-tissue metabolism, enabling galls ...

open access: yes, 2020
-Stressed plants are generally more attacked by galling insects. In this study we investigated the relationship between population abundance and species richness of galling insects on the tree Alchornea castaneaefolia A. JUSS.

Biology of the Gall Midge Spanolepis selloanae (Diptera, Cecidomyiidae), a Candidate Biological Control Agent of the Invasive Grass Cortaderia selloana

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.
