European Journal of Entomology, 2009 Body size is a main fitness component of insect parasitoids. We assessed the potential influence of maternal size of the parasitoid wasp Aphidius colemani Viereck (Hymenoptera: Braconidae: Aphidiinae) on its ability to parasitize the different instars of

Journal of Animal Ecology, EarlyView.This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Jurnal Entomologi Indonesia, 2017 Study Hyperparasitoid Existing Affected to Adul Parasitoid Behavior on Aphid, Aphis gossypii (Hemiptera: Aphididae). In general, hyperparasitoid is needed for establishing food and chain webs, but in contrary, it could become a limiting factor in ...

Aphid parasitoid responses to semiochemicals - Genetic, conditioned or learnt?
, 1997 Parasitoid foraging behaviour is known to be influenced by interactions of genetic, physiological, environmental and experiential factors. Although the role of genetics, learning and conditioning in determining responses to foraging cues has been studied

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages
Journal of Animal Ecology, EarlyView.By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

Plant-mediated effects in the Brassicaceae on the performance and behaviour of parasitoids
, 2009 Direct and indirect plant defences are well studied, particularly in the Brassicaceae. Glucosinolates (GS) are secondary plant compounds characteristic in this plant family. They play an important role in defence against herbivores and pathogens.

Insect Science, EarlyView.This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

, 2012 For successful host location, parasitoids are thought to have evolved different strategies to filter relevant olfactory cues which indicate the presence of the host. Because of their versatility in their ecology and behaviour, as well as their fine tuned

Insect Science, EarlyView.Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Juvenilhormon-Esterase, ein Schlüsselenzym in Wirt-Parasitoid-Interaktionen
, 2008 Hymenopteran endoparasitoids that develop inside their lepidopteran host may exert a multitude of interactions with their host until they are able to emerge successfully from a developmentally arrested host that finally dies.
