Using programmable infusion pump in avian species – a validation methodology in geese

Wildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Neonicotinoid pesticide limits improvement in buzz pollination by bumblebees [PDF]

, 2017
Neonicotinoid pesticides have been linked to global declines of beneficial insects such as bumblebees. Exposure to trace levels of these chemicals causes sub-lethal effects, such as reduced learning and foraging efficiency.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Effects of High-Level Acylsugar-Producing Tomato Lines on the Development of Tomato Psyllids (Hemiptera: Triozidae). [PDF]

, 2019
Acylsugars have been shown to provide activity against numerous insect pests of tomatoes. Comparison of acylsugar levels in four tomato plant lines, FA7/AS, FA2/AS, CU071026, and 'Yellow Pear', found that the acylsugar contents in the elevated acylsugar ...

A restatement of recent advances in the natural science evidence base concerning neonicotinoid insecticides and insect pollinators [PDF]

, 2015
A summary is provided of recent advances in the natural science evidence base concerning the effects of neonicotinoid insecticides on insect pollinators in a format (a ‘restatement’) intended to be accessible to informed but not expert policymakers and ...

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.

Peer review of the pesticide risk assessment for bees for the active substance clothianidin considering the uses as seed treatments and granules

EFSA Journal, 2018
EFSA was asked by the European Commission to perform an updated risk assessment of neonicotinoids, including clothianidin, as regards the risk to bees, as a follow up of previous mandates received from the European Commission on neonicotinoids.

Protecting an Ecosystem Service: Approaches to Understanding and Mitigating Threats to Wild Insect Pollinators [PDF]

, 2016
Insect pollination constitutes an ecosystem service of global importance, providing significant economic and aesthetic benefits as well as cultural value to human society, alongside vital ecological processes in terrestrial ecosystems.

Degree of insecticide exposure and access to nectar impact survival of Trissolcus japonicus, a hymenopteran parasitoid, in flowering border strips

Agricultural and Forest Entomology, EarlyView.
We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,

Matrix-Induced Sugaring-Out: A Simple and Rapid Sample Preparation Method for the Determination of Neonicotinoid Pesticides in Honey

Molecules, 2019
In the present work, we developed a simple and rapid sample preparation method for the determination of neonicotinoid pesticides in honey based on the matrix-induced sugaring-out.
