Noncrop flowering plants restore top-down herbivore control in agricultural fields [PDF]

, 2013
Herbivore populations are regulated by bottom-up control through food availability and quality and by top-down control through natural enemies. Intensive agricultural monocultures provide abundant food to specialized herbivores and at the same time ...

Using plant chemistry to improve interactions between plants, herbivores and their natural enemies: challenges and opportunities

, 2021
Plant secondary (or specialized) metabolites determine multitrophic interaction dynamics. Herbivore natural enemies exploit plant volatiles for host location and are negatively affected by plant defense chemicals that are transferred through herbivores ...

Silica nanoparticles as pesticide against insects of different feeding types and their non-target attraction of predators

Scientific Reports, 2021
The agricultural use of silica (SiO2) nanoparticles (NPs) has the potential to control insect pests while the safety and tritrophic effects on plants and beneficial natural enemies remains unknown.

The state of commercial augmentative biological control: plenty of natural enemies, but a frustrating lack of uptake

, 2012
Augmentative biological control concerns the periodical release of natural enemies. In com- mercial augmentative biological control, natural enemies are mass-reared in biofactories for release in large numbers to obtain an immediate control of pests. The

Development of a Stage- and Species-Specific RNAi System for Molecular Insights in Trichogramma Wasps

Insects
Trichogramma wasps, egg parasitoids widely used to control lepidopteran pests, have long eluded in-depth molecular mechanistic studies due to their minute size and genetic tool scarcity. While previous RNAi efforts were restricted to T.

Impact of a nonnative parasitoid species on intraspecific interference and offspring sex ratio

Scientific Reports, 2021
In an assemblage of multiple predators sharing a single prey species, the combined effects of the component species may scale unpredictably because of emergent interspecific interactions.
