Bee pollen as functional food and environmental bioindicator: current evidence and future challenges

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Bee pollen (BP), a plant‐derived product collected by honey bees, is increasingly promoted as a functional food due to its content of proteins, essential amino acids, lipids, vitamins, minerals, and bioactive compounds such as polyphenols and flavonoids.

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Major effect genes or loose confederations? The development of insecticide resistance in the malaria vector Anopheles gambiae

Parasites & Vectors, 2010
Insecticide use in public health and agriculture presents a dramatic adaptive challenge to target and non-target insect populations. The rapid development of genetically modulated resistance to insecticides is postulated to develop in two distinct ways ...

Experimental hut evaluation of bednets treated with an organophosphate (chlorpyrifos-methyl) or a pyrethroid (lambdacyhalothrin) alone and in combination against insecticide-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes. [PDF]

, 2005
BACKGROUND: Pyrethroid resistant mosquitoes are becoming increasingly common in parts of Africa. It is important to identify alternative insecticides which, if necessary, could be used to replace or supplement the pyrethroids for use on treated nets ...

Advances in research on autophagy in the maintenance of insect–microbe symbiosis

New Plant Protection, EarlyView.
Autophagy plays a dual regulatory role in insect–microbe symbiotic relationships. Beneficial symbiotic bacteria in insects participate in nutrient exchange via the TOR pathway, whereas pathogenic microbes induce immune defense through the AMPK pathway. Autophagy‐related genes regulate development and pathogen clearance during this process.

Update on resistance status of Anopheles gambiae s.s. to conventional insecticides at a previous WHOPES field site, "Yaokoffikro", 6 years after the political crisis in Côte d'Ivoire. [PDF]

, 2012
BACKGROUND: At Yaokoffikro field site near Bouaké, in central Côte d'Ivoire, a group of experimental huts built in 1996 served over many years for the evaluation of insecticides against highly resistant mosquitoes.

Targeting UDP‐Bta06664 in Bemisia tabaci: A novel strategy to reduce tomato yellow leaf curl virus transmission by impairing insect vector feeding

New Plant Protection, EarlyView.
Tomato yellow leaf curl virus upregulates the Bemisia tabaci UDP‐glycosyltransferase gene UDP‐Bta06664. RNA interference (RNAi) silencing of this gene disrupts phloem feeding—delaying E1 and shortening E2—and reduces both virus acquisition and inoculation, highlighting its potential as an RNAi target.

The entomopathogenic fungus Beauveria bassiana reduces instantaneous blood feeding in wild multi-insecticide-resistant Culex quinquefasciatus mosquitoes in Benin, West Africa. [PDF]

, 2010
BACKGROUND: Mosquito-borne diseases are still a major health risk in many developing countries, and the emergence of multi-insecticide-resistant mosquitoes is threatening the future of vector control.

Nonstationarity in wildlife disease dynamics: insights from the prairie dog–plague system

Oikos, EarlyView.
Ecological relationships often vary in strength and direction across ecosystems, a pattern that has become increasingly evident as ecology expands to broader spatial and temporal scales. Although such nonstationarity – the changing effect of predictor variables across spatiotemporal contexts – is widely acknowledged in ecological research, it has ...

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

Oikos, EarlyView.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...
