Parasitoids lay their eggs in or on a host, usually another insect. During foraging, parasitoids can encounter insects that differ in terms of host suitability and quality. At one extreme end of this spectrum are non-hosts that are unsuitable for offspring development.Non-hosts are generally ignored …

Hyperparasitoids are some of the most diverse members of insect food webs. True hyperparasitoids parasitize the larvae of other parasitoids, reaching these larvae with their ovipositor through the herbivore that hosts the parasitoid larva. During pupation, primary parasitoids also may be attacked by …

Adults of many mosquito species feed on plants to obtain metabolic energy and to enhance reproduction. Mosquitoes primarily rely on olfaction to locate plants and are known to respond to a range of plant volatiles. We studied the olfactory response of the yellow fever mosquito Aedes aegypti to methyl …

Animals can alter their foraging behavior through associative learning, where an encounter with an essential resource (e.g., food or a reproductive opportunity) is associated with nearby environmental cues (e.g., volatiles). This can subsequently improve the animal’s foraging efficiency. However, when …

1. Dynamic conditions in nature have led to the evolution of behavioural traits that allow animals to use information on local circumstances and adjust their behaviour accordingly, for example through learning. Although learning can improve foraging efficiency, the learned information can become unreliable …

Many species of parasitoid wasps use plant volatiles to locate their herbivorous hosts. These volatiles are reliable indicators of host presence when their emission in plants is induced by herbivory. Hyperparasitoids may also use information from lower trophic levels to locate their parasitoid hosts …

Global climate change is resulting in a wide range of biotic responses, including changes in diel activity and seasonal phenology patterns, range shifts polewards in each hemisphere and/or to higher elevations, and altered intensity and frequency of interactions between species in ecosystems.Oak (Thaumetopoea …

Onderzoek naar de manier waarop de leerkrachtvaardigheden verbeterd kunnen worden in het geven van de stellessen in een driejarige middenbouw stamgroep binnen het jenaplanonderwijs. Het ontwerp bestaat uit een handleiding voor het geven van stellessen; een theoretisch kader, genrekaarten, lesfase kaarten, …

In dit onderzoek is gekeken naar een geschikte methode die past bij de wensen en behoeften van de leerkrachten van groep 1/2 en de visie van de school. Vooraf aan het onderzoek kwam naar voren dat de XXX weinig aandacht schenkt aan muziekonderwijs bij de groepen 1/2, ondanks dat het wel is meegenomen …

De overlast van de eikenprocessierups (EPR) voor de gezondheid van mens en dier vraagt om aandacht en aanpakken. Op veel plekken gebeurt dat al. In de praktijk zijn verschillende middelen en maatregelen in zwang. Daarbij ontstaan vragen over de werkzaamheid, effectiviteit, (schadelijke) neveneffecten …
