The price of protection: a defensive endosymbiont impairs nymph growth in the bird cherry‐oat aphid, Rhopalosiphum padi

open access: yesInsect Science, 2018
Bacterial endosymbionts have enabled aphids to adapt to a range of stressors, but their effects in many aphid species remain to be established. The bird cherry‐oat aphid, Rhopalosiphum padi (Linnaeus), is an important pest of cereals worldwide and has ...

Silencing of Two Insulin Receptor Genes Disrupts Nymph-Adult Transition of Alate Brown Citrus Aphid

open access: yesInternational Journal of Molecular Sciences, 2017
Insulin receptors play key roles in growth, development, and polymorphism in insects. Here, we report two insulin receptor genes (AcInR1 and AcInR2) from the brown citrus aphid, Aphis (Toxoptera) citricidus.

The mayfly nymph Austrophlebioides pusillus Harker defies common osmoregulatory assumptions

open access: yesRoyal Society Open Science, 2017
Osmoregulation is a key physiological function, critical for homeostasis. The basic physiological mechanisms of osmoregulation are thought to be well established.

The complete chloroplast genome sequence of the Nymphaea capensis Thunb. (Nymphaeaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
Nymphaea capensis (Nymphaeaceae) is one of the species in subgenus Brachyceras, which usually found in tropical and subtropical areas. Here, we presented a complete chloroplast genome of Nymphaea capensis which is 159,998 bp long and has four subregions:

Genome Mining Reveals a Novel Nephthenol‐Producing Diterpene Synthase from the Sandfly Lutzomyia Longipalpis

open access: yesChemBioChem, EarlyView.
The discovery of a terpene synthase of insect origin that makes the apparently cryptic product nephthenol from geranylgeranyl diphosphate sheds light on hidden biosynthetic potential. Populations of the sandfly, Lutzomyia longipalpis, use the diterpene sobralene as a sex/aggregation pheromone, which is likely produced in the insect through the activity

Alecanochiton marquesi (Hemiptera: Coccomorpha: Coccidae), a new record for Colombia and Costa Rica, and description of its first-instar nymph

open access: yesCaldasia, 2018
The Marques’ soft scale, Alecanochiton marquesi (Hemiptera: Coccomorpha: Coccidae) is recorded from Colombia and Costa Rica on Sapotaceae (Manilkara zapota) and on Melastomataceae (Conostegia xalapensis, Miconia trinervia, and M. schlimii), respectively.

Genistein induced by Frankliniella occidentalis feeding confers resistance to insect herbivores in peanut

open access: yesNew Plant Protection, EarlyView.
The Tianfu 22 (TF22) variety was identified as resistant to thrips based on field screening carried out over two consecutive years. Metabolomic profiling showed that thrip‐infested TF22 leaves exhibited differentially accumulated metabolites, particularly enriched in phenylpropanoid and secondary metabolite biosynthesis.

The women honoured in flowering plant genera: From myth to reality

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Many flowering plant genera are named for people, but there is a gender gap in this naming, with only 6% of eponyms honouring women. Here we explore this gap by examining in detail women for whom plant genera are named. Our open shared dataset serves to make women honoured in plant genera more discoverable, resulting in further impact by allowing ...

The Cave of the Nymphs at Pharsalos

open access: yes, 2021
On the north slope of a hill called Karaplas, 1 km to the southwest of the city of Farsala (ancient Pharsalos), is a cave, well-hidden by its location on a small cliff and the surrounding vegetation. The site was first studied in the 1920's by the Italian Archaeological School at Athens.
