Natural hybridisation between Aphis grossulariae and Aphis schneideri: morphological evidence (Sternorrhyncha: Aphididae)

open access: yesEuropean Journal of Entomology, 2003
Morphometric analysis of 176 natural samples of A. grossulariae Kaltenbach, 1843 and A. schneideri (Börner, 1940) was performed, using 308 alate and 750 apterous viviparous females from 25 countries altogether.

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

open access: yesIbis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

Experimental hybridisation between Aphis grossulariae and Aphis triglochinis (Sternorrhyncha: Aphididae)

open access: yesEuropean Journal of Entomology, 2000
Aphis triglochinis and A. grossulariae clones from southern Poland produced fertile hybrid eggs under experimental conditions. Established hybrid clones expressed normal parthenogenetic reproduction but bisexual generations were obtained only in three ...

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

open access: yesInsect 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.

The complete mitochondrial genome of Paracolopha morrisoni (Baker, 1919) (Hemiptera: Aphididae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
We have determined the mitochondrial genome of Paracolopha morrisoni (Baker, 1919), a gall-forming aphid collected from Korea. The circular mitogenome of Paracolopha morrisoni is 16,330 bp long including 13 protein-coding genes, 2 ribosomal RNA genes, 22

Demographic parameters of Diuraphis noxia (Hemiptera: Aphididae) and Hippodamia variegata (Coleoptera: Coccinellidae) recorded in the context of D. noxia infesting resistant and susceptible cultivars of wheat

open access: yesEuropean Journal of Entomology, 2015
The Russian wheat aphid (RWA), Diuraphis noxia (Kurdjumov), is a serious pest of small grains and can cause losses of about 80% in wheat yields. Chemical control is ineffective against this pest so the combined use of host plant resistance and biological

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

open access: yesInsect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.
