In the field, plants suffer from attack by herbivorous insects. Plants have numerous adaptations to defend against herbivory. Not only do these defense responses reduce performance of the feeding herbivore, they also result in the attraction of natural enemies of herbivores. The majority of studies investigating plant-insect interactions addressed ...
Western flower thrips is a pest on a large variety of vegetable, fruit and ornamental crops. The damage these minute slender insects cause in agriculture through feeding and the transmission of tospoviruses requires a sustainable solution. Host-plant resistance is a cornerstone of Integrated Pest Management (IPM). Plants have many natural defense c...
Een plant heeft te maken met voortdurend wisselende lichtniveaus die soms zodanig hoog kunnen oplopen dat ze schade veroorzaken. Er bestaat een uitgebreid stelsel van verdedigingslinies op alle niveaus: blad, cel, celorganen en moleculair niveau. Soms is de voorbereiding op mogelijke lichtschade zo goed dat het productie kost.
Plants have evolved mechanisms to combat herbivory. These mechanisms can be classified as direct defences which have a negative influence on the herbivores and indirect defence that attracts natural enemies of the attacking herbivores. Both direct and indirect defences can be constantly present or induced upon attack. This study, using cucumber (Cu...
Plants form the basis of many food webs and are consumed by a wide variety of organisms, including herbivorous insects. Over the course of evolution, plants have evolved mechanisms to defend themselves against herbivory, whereas herbivorous insects have evolved counter-mechanisms to overcome these defences (a.k.a. co-evolutionary arms races). Plant...
Summary In natural and agricultural ecosystems, plants are exposed to a wide diversity of abiotic and biotic stresses such as drought, salinity, pathogens and insect herbivores. Under natural conditions, these stresses do not occur in isolation but commonly occur simultaneously. However, plants have developed sophisticated mechanisms to survive and...
Summary Whitefly is an insect pest that has systematically spread into colder latitudes for the past two decades and it poses a serious threat to crops, mainly due to the viruses for which it acts as a vector. As the application of synthetic pesticides is often less effective due to development of resistance or restricted by crop- and country-speci...
SUMMARY Plants as primary producers in terrestrial ecosystems are under constant threat from a multitude of attackers, which include insect herbivores. In addition to interactions with detrimental organisms, plants host a diversity of beneficial organisms, which include microbes in the rhizosphere. Furthermore, the interactions between plants and s...
Filmpje van de Universiteit van Nederland: Hoe zorgen zombierupsen voor een beter milieu? Als je verschillende soorten organismen in een ecosysteem hebt, houden ze elkaar in balans. Daarom is biodiversiteit goed voor het milieu. Dit is ook waarom insectenplagen soms erger kunnen worden door het gebruik van pesticiden. Prof. dr. Louise Vet van Wagen...
