The symptom and genetic diversity of cassava brown streak viruses infecting cassava in East Africa [PDF]

open access: yes, 2012
The genetic and symptom diversity of six virus isolates causing cassava brown streak disease (CBSD) in the endemic (Kenya, Mozambique, and Tanzania) and the recently affected epidemic areas (Uganda) of eastern Africa was studied.

Biochemical and metabolic responses of cotton variety XLZ54 to Thrips tabaci and screening of resistance characterization indicators

open access: yesPest Management Science, EarlyView.
Cotton varieties resistant to Thrips tabaci exhibit lower soluble sugar and free amino acid levels, with smaller post‐infestation increases in these nutrients, resulting in reduced feeding rates and lighter damage. Key resistance evaluation indices include: damage severity, soluble sugars, free amino acids, soluble proteins, superoxide dismutase ...

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

From Theatre to Transformation: Learning, Action, and Diffusion for SDG2 in Cambodia

open access: yesSustainable Development, EarlyView.
ABSTRACT The arts are envisioned as able to help address the longstanding ‘implementation gap’ between research and realisation of the Sustainable Development Goals (SDGs). For SDG2 (Zero Hunger), Forum Theatre offers a participatory alternative to top‐down interventions, yet its impacts have not been evaluated using rigorous, mixed‐methods that are ...

Cretaceous lacewing larvae with binocular vision demonstrate the convergent evolution of sophisticated simple eyes

open access: yesInsect Science, EarlyView.
We report three ca. 100 million‐year‐old lacewing larvae with extraordinarily large stemmata. One of them additionally has a very wide head, which represents a previously unknown morphology. The arrangement of the stemmata indicates stereoscopic vision in these predatory larvae.

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

open access: yesInsect 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 ...

Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

open access: yesInsect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

open access: yesInsect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...
