Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

Agricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

Life tables and demographic statistics of Russian wheat aphid (Hemiptera: Aphididae) reared at different temperatures and on different host plant growth stages

European Journal of Entomology, 2009
Laboratory experiments were used to investigate the influences of 25 combinations of temperature and barley plant growth stage (5 × 5 factorial combination of temperature and barley plant growth stage) on the development, survival and reproduction of the

Evidence for positive population‐level responses but not individual performance of sycamore aphids under elevated CO2

Agricultural and Forest Entomology, EarlyView.
The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...

Effect of summer flush leaves of the Daimyo oak, Quercus dentata, on density, fecundity and honeydew excretion by the drepanosiphid aphid Tuberculatus quercicola (Sternorrhyncha: Aphididae)

European Journal of Entomology, 2004
The aphid Tuberculatus quercicola (Matsumura), a non host-alternating species, lives on Daimyo oak, Quercus dentata Thumberg, and other species of oak. In summer there was a significant reduction in the total amino acid concentration in phloem sap of the

The complete mitochondrial genome of Rhopalosiphum nymphaeae (Linnaeus, 1761) (Hemiptera: Aphididae)

Mitochondrial DNA. Part B. Resources, 2020
Rhopalosiphum nymphaeae (Linnaeus, 1761) is a heteroecious polyphagous aphid, which can survive underwater. We have determined mitochondrial genome of R. nymphaeae collected in Korea. The circular mitogenome of R.

Reconsidering the importance of Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) as a crop pest

Agricultural and Forest Entomology, EarlyView.
Four‐year field monitoring and laboratory studies revealed M. dirhodum occurs regularly in barley with high reproductive potential and extended adult longevity. Populations peaked during vulnerable crop stages, creating optimal conditions for BYDV transmission during critical infection windows. M.

The influence of cutting height on arthropods in farm grassland

Insect Conservation and Diversity, EarlyView.
Mowing at a cutting height of 13 cm slightly reduced the immediate negative impact of mowing compared to mowing at a height of 7 cm. Medium‐term effects overrode this benefit: the number of vegetation‐dwelling arthropods remained strongly reduced two and four weeks after mowing, regardless of the cutting height.
