ABSTRACT Plant defensins (PDFs) are cysteine‐rich antimicrobial peptides (AMPs) that are important components of plant immunity. They occur constitutively in various plant tissues but are also upregulated upon stress. Therefore, these molecules are of great interest as markers for the diagnosis of early forest stress response in plants at the molecular

Drying processes in the Brazilian palm swamps or Veredas, impact the gall community in adjacent vegetation by reducing the abundance of more sensitive galls, while more resilient galls acclimate to increased dryness by developing thicker protective tissues. Abstract Galls are new plant organs formed in response to the stimuli of gall‐inducing organisms,

Studies on the insect fauna especially gall midges (Diptera: Cecidomyiidae) of Tamil Nadu are relatively less in comparison to the other Indian region. Only fourty eight species of Cecidomyiidae have been reported so far from this region.

The evolutionary ecology of interactive synchronism: The illusion of the optimal phenotype [PDF]
In this article, we discuss some ecological-evolutionary strategies that allow synchronization of organisms, resources, and conditions. Survival and reproduction require synchronization of life cycles of organisms with favourable environmental ...

In this study, we demonstrate that urbanization intensity reduces the abundance of stem galls on Turnera subulata, while increased vegetation cover and plant vigor promote higher occurrence and abundance. These findings highlight the importance of native vegetation in sustaining specialized insect‐plant interactions and provide evidence that plant ...

Arthropods Associated With Purple Loosestrife in Illinois Wetlands [PDF]
We estimated and described the arthropod fauna on purple loosestrife (Lythrum salicaria) plants in northeastern Illinois wetlands. A total of 1063 individual arthropods were collected—930 insects and 133 arachnids.

Ecological plasticity and genetic diversity of the mango blossom gall midge, Procontarinia Mangiferae (Felt), in Reunion Island : O306F12 Ecology [PDF]
Phytophagous insects that belong to the Cecidomyiidae family are among the most closely associated with their host plants. Phytophagous insects can specialize not only on a unique host plant but on particular parts of plants as well.

Variation in physiological host range in three strains of two species of the entomopathogenic fungus Beauveria [PDF]
Knowledge of the host range of a biocontrol agent (BCA) is fundamental. Host range determines the BCA's economic potential, as well as the possible risk for non-target organisms. Entomopathogenic fungal strains belonging to the genus Beauveria are widely
