The Habits of the Aculeate Hymenoptera.—III [PDF]

open access: yesPsyche: A Journal of Entomology, 1894
While inspecting during the past summer, the fruit orchard of a friend residing in this neighborhood, my attention was attracted by the peculiar appearance of the leaves of a young plum tree. At the first glance, I thought it might be affected by Aphides, but, on closer examination, I found unmistakable evidence of the work of a leaf-cutting bee, in ...

Semi‐tilling maintains the arthropod food web structure but decreases biological pest control in olive groves

open access: yesAnnals of Applied Biology, EarlyView.
Semi‐tillage, a widely used agricultural method to improve water availability and minimise soil erosion in crops, may compromise pest control in olive groves. Stable isotopes (N15 and C13) analysis showed an effect of semi‐tillage in the composition of the basal resources of potential natural enemies in the three olive grove strata: These changes may ...

Spatial distribution of Cynips quercusfolii (Hymenoptera: Cynipidae) galls on leaves and within the crowns of oak trees

open access: yesEuropean Journal of Entomology, 2013
The factors that affect oviposition and consequently spatial distribution of the galls of many gall makers are poorly understood. Knowledge of these factors could result in a better understanding of the mechanisms that initiate and regulate the ...

A New Species of \u3ci\u3ePediobius\u3c/i\u3e (Hymenoptera: Eulophidae) Parasitizing \u3ci\u3eChyliza Apicalis\u3c/i\u3e (Diptera: Psilidae) in Ash Trees Attacked by \u3ci\u3eAgrilus Planipennis\u3c/i\u3e (Coleoptera: Buprestidae) [PDF]

open access: yes, 2018
Pediobius chylizae, spec. nov. (Hymenoptera: Eulophidae), is described as new and illustrated. This parasitoid has been reared from the puparia of Chyliza apicalis Loew (Diptera: Psilidae) collected from under the bark of ash trees (Oleaceae: Fraxinus ...

Notes on Parasitic Hymenoptera [PDF]

open access: yesBulletin of Entomological Research, 1923
During the past fifteen years the attention of Economic Entomologists in Central America and the West Indies has been increasingly directed to the damage done by species of the genus Brassolis to the foliage of coconut and other palms. In some of the scattered papers (q.v.

Preserving Short‐Sward Natural Grasslands May Provide Suitable Foraging Habitat for a Climate‐Threatened Alpine Species Along Ski‐Pistes

open access: yesAnimal Conservation, EarlyView.
Investigating the ultimate factors that underpin the impacts of ski‐pistes on alpine species is crucial to identify concrete mitigation strategies. This is urgently needed given that winter sports are expanding in mountain ranges worldwide. We evaluated the impacts of ski‐pistes on the foraging behaviour of the white‐winged snowfinch, an iconic alpine ...

Distribution, abundance and host association of two parasitoid species attacking frugivorous drosophilid larvae in central Japan

open access: yesEuropean Journal of Entomology, 2010
In central Japan Ganaspis xanthopoda and Asobara japonica commonly parasitize the larvae of frugivorous drosophilids, mainly in montane forests, and urban environments and small groves, respectively.

Climate Change‐Induced Distribution Shifts of Keratin‐Feeding Beetle Omorgus (Omorgus) suberosus: Implications for Olive Ridley Sea Turtle Lepidochelys olivacea Conservation

open access: yesAnimal Conservation, EarlyView.
Our study projects significant climate change‐induced distribution shifts of a keratin‐feeding beetle Omorgus suberosus, with expansions into higher latitudes in Europe and North America and notable habitat losses in tropical regions by 2100. Ecological niche models predict a global habitat reduction of 9.5% under SSP2–4.5 and 20.8% under SSP5–8.5 ...
