Acute effect of low-dose thiacloprid exposure synergised by tebuconazole in a parasitoid wasp.

Abstract: Agricultural practices often involve tank-mixing and co-application of insecticides with fungicides to control crop pests. However, natural methods relying on biological control agents such as hymenopteran parasitoids have been shown to be highly effective in suppressing crop pest populations. The current body of insecticide risk assessment data accounting for fungicide co-application is very small, the present study being the first to examine this in a parasitoid wasp.

Agriculturally dominated landscapes reduce bee phylogenetic diversity and pollination services

Land-use change threatens global biodiversity and may reshape the tree of life by favoring some lineages over others. Whether phylogenetic diversity loss compromises ecosystem service delivery remains unknown. We address this knowledge gap using extensive genomic, community, and crop datasets to examine relationships among land use, pollinator phylogenetic structure, and crop production.

Varroa destructor

Varroa destructor feeds primarily on honey bee fat body tissue and not hemolymph

varroa destructor - honey beeVarroa destructor causes considerable damage to honey bees and subsequently the field of apiculture through just one process: feeding. For five decades, we have believed that these mites consume hemolymph like a tick consumes blood, and that Varroa cause harm primarily by vectoring viruses.

There’s an entire industry built around dieting. Most of its products are intended to help people lose weight, gain muscle, or live longer.
But as the global human population steadily climbs, scientists are scrambling to devise a diet plan that can feed 10 billion people by 2050.

Cardiovascular disease

Cardiac risk factors and prevention

Abstract: Objective Cardiovascular disease (CVD) is a leading cause of mortality and morbidity in the USA. The role of occupational exposures to chemicals in the development of CVD has rarely been studied even though many agents possess cardiotoxic properties. We therefore evaluated associations of self-reported exposures to organic solvents, metals and pesticides in relation to CVD prevalence among diverse Hispanic/Latino workers.

Ban for insecticides

University of California – Davis Health

Summary: Public health experts have found there is sufficient evidence that prenatal exposure to widely used insecticides known as organophosphates puts children at risk for neurodevelopmental disorders.

Leading researchers call for a ban on widely used insecticides.

Use of organophosphates has lessened, but risks to early brain development still too high.

The pesticide-free town

What do a pharmacist, a nursery school teacher and an architect all have in common?
They all became unlikely activists in the historic case of the first pesticide-free town.
