Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Study of genetic variability and correlation in interspecific derivatives of Pigeonpea [Cajanus cajan (L.) Millsp.] [PDF]

Electronic Journal of Plant Breeding, 2010
Forty interspecific derivatives (ISD) of Pigeonpea along with five national checks derived from ICRISAT, Patancheru,Hyderabad and one local check were screened to study the extent of genetic variability for yield and yield contributingcharacter and their

Phenological description for the initial development stage of five Brazilian native forest species according to BBCH scale

Annals of Applied Biology, EarlyView.
Morphology of the two main growth stages—germination and initial development of the forest species Ceiba speciosa (co, cotyledon; eo, eophyll; hp, hypocotyl; me, metaphyll; pk, prickles; pr, primary root; se, seed; sr, secondary root). Abstract A specific phenological scale designated for each forest species facilitates the standardization of different

Ecological factors affecting the establishment of the biological control agent Gargaphia decoris Drake (Hemiptera: Tingidae) : a thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Plant Science at Massey University, Manawatu, New Zealand [PDF]

, 2017
The Brazilian lace bug (Gargaphia decoris Drake (Hemiptera:Tingidae)) was released in New Zealand in 2010 for the biological control of the invasive weed woolly nightshade (Solanum mauritianum Scopoli (Solanaceae)).

Above- and belowground herbivory jointly impact defense and seed dispersal traits in Taraxacum officinale [PDF]

, 2014
Plants are able to cope with herbivores by inducing defensive traits or growth responses that allow them to reduce or avoid the impact of herbivores. Since above- and belowground herbivores differ substantially in life-history traits, for example feeding

Anholocyclic overwintering of Myzus persicae: Host plant selection as a driver for aphid performance and survival

Annals of Applied Biology, EarlyView.
The green peach aphid, Myzus persicae, is the main virus vector in sugar beet. We examine its performance on potential winter hosts as well as the host selection and overwintering success of anholicyclic aphids in order to improve forecasting models for virus outbreaks through targeted monitoring of suitable winter hosts. Abstract Virus yellows (VY) is

Constitutive Expressor of Pathogenesis-Related Genes5 affects cell wall biogenesis and trichome development

BMC Plant Biology, 2008
Background The Arabidopsis thaliana CONSTITUTIVE EXPRESSOR OF PATHOGENESIS-RELATED GENES5 (CPR5) gene has been previously implicated in disease resistance, cell proliferation, cell death, and sugar sensing, and encodes a putative membrane protein of ...

Is there a role for cannabidiol in obesity, metabolic syndrome and binge eating?

British Journal of Pharmacology, EarlyView.
Cannabidiol (CBD) is one of the most abundant phytocannabinoids isolated from the Cannabis sativa plant. CBD is a lipophilic, non‐intoxicating substance that differently from Δ9‐tetrahydrocannabinol (Δ9‐THC) does not present the typical profile of a drug of abuse.

Competitive Interactions Between Generalist Predators and Their Effects on Shared and Non‐Shared Pests in a Greenhouse Crop

Entomologia Experimentalis et Applicata, EarlyView.
Orius laevigatus engages in unidirectional intraguild predation on Transeius montdorensis. Despite this, both predators coexisted and suppressed the shared thrips prey. Aphids, a non‐shared prey, were effectively controlled by O. laevigatus even when its population was limited due to intraguild predation. T.

Nutrient addition, but not vertebrate predator exclusion, shapes arthropod communities and herbivory in a temperate forest

Ecological Entomology, EarlyView.
We experimentally manipulated top‐down (predator exclusion) and bottom‐up (fertilisation) forces in a temperate forest understory to test effects on arthropod densities, body sizes and herbivory. Predator exclusion had no detectable effect on arthropod density, herbivory damage or body size, whereas fertilisation increased herbivory damage and ...
