1. Impact of parasitoid-associated polydnaviruses on plant-mediated herbivore interactions

Author:

Subject:
phytophagous insects,   etc   ; Polydnaviridae; food plants; parasitism; parasitoids; phenotype; plant damage; saliva;     Show all 8 Subjects
Abstract:
... Insect herbivores interact via plant-mediated interactions in which one herbivore species induces changes in plant quality that affects the performance of a second phytophagous insect that shares the food plant. These interactions are often asymmetric due to specificity in induced plant responses to herbivore attack, amount of plant damage, elicitors in herbivore saliva and plant organ damaged by ...

Abstract:
... Chronic anthropogenic disturbance (CAD) and climate change represent two of the major threats to biodiversity globally, but their combined effects are not well understood. Here we investigate the individual and interactive effects of increasing CAD and decreasing rainfall on the composition and taxonomic (TD), functional (FD) and phylogenetic diversity (PD) of plants possessing extrafloral nectari ...

Abstract:
... Dietary protein and digestible carbohydrates are two key macronutrients for insect herbivores, but the amounts and ratios of these two macronutrients in plant vegetative tissues can be highly variable. Typically, insect herbivores regulate their protein-carbohydrate intake by feeding selectively on nutritionally complementary plant tissues, but this may not always be possible. Interestingly, lab e ...

Abstract:
... Plants are often sequentially attacked by multiple herbivores; feeding by one herbivore can alter host plant quality that affects the performance of subsequent herbivores. Previous studies suggest that silicon (Si) is a highly inducible defence in grasses (Poaceae) following herbivory, so could mediate such temporally separated insect herbivore interactions. Elevated atmospheric CO₂ concentrations ...

Abstract:
... Conversion from natural forest to timber plantation is an important cause of pristine forests loss. These changes alter community structure and cause a decrease in the diversity of plant communities. Leaf functional traits, which are an important defensive strategy, might also be influenced by such alterations. Altogether, shifts from natural forest to timber plantation may lead to profound change ...

Abstract:
... The composition and richness of herbivore and plant assemblages change along climatic gradients, but knowledge about associated shifts in specialization is scarce and lacks controlling for the abundance and phylogeny of interaction partners. Thus, we aimed to test whether the specialization of phytophagous insects in insect‐plant interaction networks decreases toward cold habitats as predicted by ...

However, the extent to which these networks are affected by chronic anthropogenic disturbances and aridity, the most common threats to biodiversity in dry forests, remain unknown. In this study, we examined plant and insect herbivore communities and their interaction ...

Abstract:
... Because the diet of many herbivorous insects is restricted to closely related taxa with similar chemistry, intercropping with diverse plant communities may reduce both pest populations and reliance on chemical pesticides in agroecosystems. We tested whether the effectiveness of intercropping against herbivorous insects depends on the phylogenetic relatedness of neighboring crops, using butternut s ...

Abstract:
... KEY MESSAGE: Calmodulin-like-proteins (CML) belong to a family of calcium-sensing proteins that are unique for plants and involved in many different developmental and stress-related reactions. In defense against herbivory, some pathogens and drought, CML37 acts as a positive and CML42 as a negative regulator, respectively. We provide evidence that both CMLs act antagonistically in the regulation o ...

Abstract:
... Plants leave legacy effects in the soil they grow in, which can drive important vegetation processes, including productivity, community dynamics and species turnover. Plants at the same time also face continuous pressure posed by insect herbivores.

Abstract:
... Interspecies competition affects the distribution, quantity, and community structure of insects, especially among closely-related (congeners) species. Some ecological factors differentially affect the fitness of co-existing species, thus conferring an advantage on one competitor, and then the structure of communities. The present work evaluated the effects of high temperature and natural enemies o ...

Abstract:
... Warm‐season turfgrasses are conventionally produced and maintained as cultivar monocultures, which leaves them less resilient to pest attack than more diverse plantings. Recent evidence has indicated that mixing St. Augustinegrass [Stenotaphrum secundatum (Walter) Kuntze] cultivars can provide pest management benefits compared with cultivar monocultures. Research in other systems has shown that th ...

We examined a possible mechanism that dietary protein and sodium co‐limit insec ...

Such defense pathways are influenced by a multitude of factors; however, ...
