Diversity and abundance of arboreal psocids (Psocoptera) along latitudinal gradients in northern Europe

open access: yesEuropean Journal of Entomology, 2014
Psocids are small insects that feed primarily on fungi, algae, lichens and organic detritus. Although they are relatively common in forest ecosystems, the general patterns in their abundance and diversity in boreal forests are still poorly known.

Avaliando a interrupção da conectividade longitudinal em assembleias de macroinvertebrados em um rio semi-árido [PDF]

open access: yes, 2017
Aim: Our aim in this study was evaluate the effects of flow regulation for irrigation on the macroinvertebrate assemblages in a semiarid river. Methods:We sampled two reaches in Dulce River; one placed upstream a weir that diverts flow into a network of ...

Arthropod Infestation in Samples of Stored Seeds in the Czech Republic

open access: yesCzech Journal of Genetics and Plant Breeding, 2004
Twenty-one types of seed samples (mainly vegetable and grass seed) were analysed in laboratory and 60% arthropod infestation (14 Acarina, 5 Psocoptera species) was found.

Weight losses of wheat grain caused by psocid infestation (Liposcelis bostrychophila: Liposcelididae: Psocoptera)

open access: yesPlant Protection Science, 2002
ocids are commonly found to be a persistent pest in structures of grain stores. Grain residues are potential pest reservoirs that serve as sources of grain re-infestation. Weight losses caused by psocids on broken wheat kernels were measured.

Soil organisms in organic and conventional cropping systems. [PDF]

open access: yes, 2002
Apesar do crescente interesse pela agricultura orgânica, são poucas as informações de pesquisa disponíveis sobre o assunto. Assim, num Argissolo Vermelho-Amarelo distrófico foram comparados os efeitos de sistemas de cultivo orgânico e convencional, para ...

Herbivory increases diversification across insect clades. [PDF]

open access: yes, 2015
Insects contain more than half of all living species, but the causes of their remarkable diversity remain poorly understood. Many authors have suggested that herbivory has accelerated diversification in many insect clades. However, others have questioned

Nest boxes as microhabitats supporting diverse arthropod communities

open access: yesEcological Entomology, EarlyView.
Diverse Micro‐Habitats: Nest boxes supported 3634 arthropods from 82 families, highlighting their significant conservation value as artificial micro‐habitats for diverse invertebrate communities beyond their primary use for birds. Occupancy Boosts Diversity: Occupied nests exhibited significantly higher arthropod richness, abundance and Shannon ...

Generic definitions and species assignments in the family Epipsocidae (Psocoptera) [PDF]

open access: yes, 1998
The family Epipsocidae is defined, with the addition of one character not previously used. The genus Dimidistriata Li and Mockford is removed from Epipsocidae and tentatively placed in the family Dolabellopsocidae. The genus Parepipsocus Badonnel remains

Investigation of the global transportation of Culicoides biting midges, vectors of livestock and equid arboviruses, from flower‐packing plants in Kenya

open access: yesMedical and Veterinary Entomology, EarlyView.
Arboviral diseases spread by Culicoides biting midges have been introduced into Europe by unknown means. A possible route is the carriage of midges with cut flowers shipped to flower markets. We sampled Culicoides in and around a cut flower farm in Kenya; midges were caught in the vicinity and a greenhouse, but not where flowers are processed.
