Journal of Crop Protection, 2019 The decline of biodiversity, specifically of insects is one of the major topics in conservation biology. In several countries of Europe, recent studies have shown a severe decline in species number and biomass of insects. In most countries of much higher

Flooding affects fluctuating asymmetry but not growth of a riparian orbweaving spider
Ecological Entomology, EarlyView.In a mesocosm experiment we assessed the impact of flood on aquatic insect emergence and on spider development using geometric morphometric analysis of fluctuating asymmetry. We observed 45% higher emergence in flooded mesocosm throughout the season. Spiders did not grow bigger but exhibited ~15% lower fluctuating asymmetry than in controls.

Grasshopper control in Missouri forage crops and pastures (1993) [PDF]
, 1993 Grasshoppers are relatively large insects, capable of doing considerable damage to many crops. In early summer, grasshoppers normally feed on grasses and weeds in non-crop areas, and later in the season, they move into fields.

Insect Conservation and Diversity, EarlyView.We studied co‐occurrences and potential novel interactions between the invasive ladybird Harmonia axyridis and local biota (plants, arthropods and fungi) across Argentina using citizen science records. We detected co‐occurrences (mainly Asteracea and Aphididae) and previously unreported interactions (predation, parasitism, interspecific mating and ...

European Journal of Entomology, 2018 The water-hyacinth grasshopper, Cornops aquaticum, occurs in freshwater environments in the New World between latitudes 23°N and 35°S. At the southernmost margin of this distribution the populations are polymorphic for three centric fusions (Robertsonian

Grasshoppers confirm mild winter [PDF]
, 2002 If we use grasshoppers as a gauge of winter severity then the winter of 2001-2002 was certainly an insect-friendly winter. I noted in the December 2001 Integrated Crop Management newsletter that a few differential grasshoppers had survived around Ames ...

Sequence Expression of Supernumerary B Chromosomes: Function or Fluff? [PDF]
, 2019 B chromosomes are enigmatic heritable elements found in the genomes of numerous plant and animal species. Contrary to their broad distribution, most B chromosomes are non-essential. For this reason, they are regarded as genome parasites.

First Record of Fusarium verticillioides as an Entomopathogenic Fungus of Grasshoppers
Journal of Insect Science, 2011 Fusarium verticillioides (Saccardo) Nirenberg (Ascomycota: Hypocreales) is the most common fungus reported on infected corn kernels and vegetative tissues, but has not yet been documented as being entomopathogenic for grasshoppers.

Social media highlights the overlooked impact of cats on arthropods
Insect Conservation and Diversity, EarlyView.The impact of domestic cats on vertebrate biodiversity is unequivocal; however, we still know little about their effects on arthropods. By analysing over 17,000 photos and videos from social media platforms (iStock and TikTok), we documented 550 predation events of cats on arthropods.
