Development of RNAi in Insects and RNAi-Based Pest Control
In agricultural systems, insect pests can cause crop damage mainly through loss in yield or quality resulting in a loss in profits for farmers. Worldwide pests cost billions of dollars due to damage and use of pesticides. Chemical pesticides are still the major approach for controlling insect pests, but they are associated with significant hazards to the environment and human health. The altern...
متن کاملComparative Genomic Analysis of the Endosymbionts of Herbivorous Insects Reveals Eco-Environmental Adaptations: Biotechnology Applications
Metagenome analysis of the gut symbionts of three different insects was conducted as a means of comparing taxonomic and metabolic diversity of gut microbiomes to diet and life history of the insect hosts. A second goal was the discovery of novel biocatalysts for biorefinery applications. Grasshopper and cutworm gut symbionts were sequenced and compared with the previously identified metagenome ...
متن کاملDoes anthropogenic nitrogen deposition induce phosphorus limitation in herbivorous insects?
Anthropogenic nitrogen deposition has shifted many ecosystems from nitrogen (N) limitation to phosphorus (P) limitation. Although well documented in plants, no study to date has explored whether N deposition exacerbates P limitation at higher trophic levels, or focused on the effects of induced plant P limitation on trophic interactions. Insect herbivores exhibit strict N : P homeostasis, and s...
متن کاملConserving herbivorous and predatory insects in urban green spaces
Insects are key components of urban ecological networks and are greatly impacted by anthropogenic activities. Yet, few studies have examined how insect functional groups respond to changes to urban vegetation associated with different management actions. We investigated the response of herbivorous and predatory heteropteran bugs to differences in vegetation structure and diversity in golf cours...
متن کاملTesting Two Methods that Relate Herbivorous Insects to Host Plants
Insect herbivores are integral to terrestrial ecosystems. They provide essential food for higher trophic levels and aid in nutrient cycling. In general, research tends to relate individual insect herbivore species to host plant identity, where a species will show preference for one host over another. In contrast, insect herbivore assemblages are often related to host plant richness where an are...
