Anti-aphrodisiac compounds of male butterflies increase the risk of egg parasitoid attack by inducing plant synomone production [PDF]

, 2009
During mating in many butterfly species, males transfer spermatophores that contain anti-aphrodisiacs to females that repel conspecific males. For example, males of the large cabbage white, Pieris brassicae (Lepidoptera: Pieridae), transfer the anti ...

Significant resource niche overlap between competing parasitoids does not prevent their successful co‐existence

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Different species that exploit the same resources can sometimes co‐exist in the same habitat through resource sharing. For example, if resources are superabundant, then they can be easily partitioned interspecifically among different individuals. However, when resources

The Thermal Adaptability of Sclerodermus guani Xiao et Wu (Hymenoptera: Bethylidae), an Important Parasitoid of Long-Horned Beetles in China

Biology
Sclerodermus guani is the most extensively studied and widely used parasitoid wasp for controlling forest trunk-boring pests in China, with temperature being a key environmental factor affecting its development and reproduction.

Generation cycles in experimental populations of a multivoltine insect

Journal of Animal Ecology, EarlyView.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Web architecture alteration of the orb web weaving spider Metellina merianae (Araneae, Tetragnathidae) induced by the parasitoid Megaetaira madida (Ichneumonidae, Polysphincta group)

Arachnologische Mitteilungen, 2016
The polysphinctine wasp Megaetaira madida (Haliday, 1838) is a koinobiont ecto-parasitoid of spiders of the genus Metellina. Under the influence of the parasitoid’s final instar larva, the spider host M. merianae (Scopoli, 1763) built a three-dimensional

Discovery of two Palearctic Bootanomyia Girault (Hymenoptera, Megastigmidae) parasitic wasp species introduced to North America [PDF]

Journal of Hymenoptera Research
Invasive species are among the greatest threats to ecosystems, but our ability to detect species introductions varies across taxa. Parasitoid wasps, though one of the most species-rich groups of all animals, are small and have ephemeral adult stages ...

Parasitoid Wasps: From Natural History to Genomic Studies [PDF]

Current Biology, 2010
The sequencing of three Nasonia genomes provides new insights on the molecular signature associated with parasitoid lifestyle, allows comparison with the social honey bee, and enables the identification of genes underlying between-species and sex-specific differences.

Notes on \u3ci\u3eTaeniogonalos Gundlachii\u3c/i\u3e (Hymenoptera: Trigonalidae) From Wisconsin [PDF]

, 2018
This is the first report of Taeniogonalos gundlachii (Cresson) (Hymenoptera: Trigonalidae) from Wisconsin and of this hyperparasitoid reared from the initial host Euchaetes egle (Drury) (Lepidoptera: Arctiidae).

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

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 ...

Organic farming enhances parasitoid diversity at the local and landscape scales [PDF]

, 2015
1. The magnitude of the benefits derived from organic farming within contrasting managed landscapes remains unclear and, in particular, the potential scale-dependent response of insect parasitoids is relatively unexplored.
