Chemical ecology of egg parasitoids associated with true bugs [PDF]

open access: yes, 2012
Parasitoids representing some 15 families of Hymenoptera develop in insect eggs; three of these families, Platygastridae (= Scelionidae), Mymaridae, and Encyrtidae, are associated with Heteroptera.

Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 598-620, May 2026.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

New teratological cases in Platygastridae and Pteromalidae (Hymenoptera)

open access: yesTURKISH JOURNAL OF ZOOLOGY, 2014
Very few cases of teratological specimens, i.e. specimens displaying morphological abnormalities, have been cited among Platygastridae and Pteromalidae. From the Platygastridae we present 5 cases of symphysocery [A8-A9 in Metaclisis sp.; A3-A5 and A7-A9 in Sceliomorpha sp.; A5-A6 in Scelio sp.

Solving the trophic puzzle: Host–parasite associations in Neotropical fig wasps associated with fig trees of section Americanae

open access: yesEcological Entomology, Volume 51, Issue 2, Page 284-294, April 2026.
We determined the trophic associations among fig wasp species associated with Ficus citrifolia by integrating gall morphology, the temporal sequence of wasp colonization, and oviposition behaviour. Dissection of galls produced by four gall‐inducing species at a late developmental phase enabled direct identification of occupants and inference of host ...

Vegetation biomass and landscape context influence web‐building spider dietary breadth in urban vacant lots

open access: yesEcological Entomology, Volume 51, Issue 1, Page 126-140, February 2026.
Spider dietary breadth and overlap increased with imperviousness, suggesting that prey and spiders are concentrating in vacant lots in these landscapes. Higher vegetation biomass, which results from reduced mowing frequency, was associated with increased dietary breadth and shared prey between spiders.

Synopeas ruficoxum Buhl (Hymenoptera, Platygastridae) is a natural enemy of soybean gall midge, Resseliella maxima Gagné (Diptera, Cecidomyiidae) [PDF]

open access: yesJournal of Hymenoptera Research
Platygastridae (Hymenoptera) is known as a ‘dark taxon’ as it is highly diverse and understudied. Within Platygastridae, one of the largest genera is Synopeas Förster, species of which parasitize Cecidomyiidae (Diptera).
