Regenerative wheat management: The relative effects of farm practices on the biodiversity of invertebrates

Insect Conservation and Diversity, EarlyView.
Wheat in North America harbours a diverse insect community (565 morphospecies were identified in this study), and pests represented <7% of specimens collected. Regenerative wheat management promoted insect diversity without increasing pest populations.

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Bait visitation by Formica lemani (Hymenoptera: Fomicidae) indicates shortage of carbohydrates in alpine grasslands

European Journal of Entomology, 2018
Insights can be gained by analysing the feeding decisions of animals in terms of nutrient demands at a species or community level. Using carbohydrate and protein food baits, resource use and food preferences of Formica (Serviformica) lemani were ...

Primer registro de Cylindromyremex Mayr (Hymenoptera: Formicidae) para Colombia [PDF]

, 1997
Cylindromyrmex Mayr (Formicidae: Cerapachyinae) es uno de los géneros de hormigas menos conocidos. Se han descrito diez especies restringidas a la región neotropical (Bolton 1995), cuya sistemática y biología han sido muy poco estudiadas (Brown 1975)

Interactions of land use and climate change disproportionately impact Lepidoptera of the five major insect orders

Insect Conservation and Diversity, EarlyView.
Land use and climate change are two major environmental pressures that interact to impact insect biodiversity. We compared the impacts of land use alone and of the interaction between land use and climate change on the five major insect orders. Most impacted were the Lepidoptera, showing 91% lower total abundance in sites of high‐intensity agriculture ...

Una nueva especie del género Rossomyrmex Arnoldi, 1928 de Turquía (Hymenoptera, Formicidae)

Graellsia, 2007
Se describe Rossomyrmex anatolicus, nueva especie encontrada en las llanuras de Anatolia (Turquía). Muy parecida a R. proformicarum por la abundante pilosidad, se diferencia de ésta por el peciolo, que se estrecha gradualmente hasta el ápice.

Disc Mower Modifications to Reduce Suction Effects Do Not Decrease Insect Losses During Grassland Mowing

Journal of Applied Entomology, EarlyView.
ABSTRACT Among other anthropogenic factors, intensive agriculture, including frequent mowing, has largely contributed to the decline of the grassland fauna in Central Europe. Disc mowers, the predominant mowing technology, have long been suspected to cause high arthropod mortality mainly through suction generated by slanted blades.

Some ethological aspects of the trophobiotic interrelations between ants (Hymenoptera: Formicidae) and larvae of the sawfly Blasticotoma filiceti (Hymenoptera: Blasticotomidae)

European Journal of Entomology, 2011
Some ethological aspects of the interrelations between ants and the larvae of Blasticotoma filiceti Klug, 1834 were investigated in the Altai Republic and Novosibirsk Region in 2006-2008.

Urban ants as potential mechanical vectors of pathogenic and antibiotic‐resistant bacteria in a Brazilian hospital

Medical and Veterinary Entomology, EarlyView.
Nine ant taxa were identified in a Brazilian hospital, with Tapinoma melanocephalum and Dorymyrmex brunneus being the most abundant. Eighty‐five percent of collected ants yielded detectable bacterial growth, including clinically relevant genera such as Acinetobacter, Pseudomonas, Escherichia coli and Pluralibacter.

Ant diversity (Hymenoptera: Formicidae) and predation by ants on the different stages of the sugarcane borer life cycle Diatraea saccharalis (Lepidoptera: Crambidae)

European Journal of Entomology, 2012
The sugarcane borer Diatraea saccharalis is an important pest of sugarcane and ants are one of its main predators. The practice of burning sugarcane straw in situ after harvest has been gradually replaced in Brazil by other practices.
