ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Adaptive aggregation by spider mites under predation risk
Grouping together is a commonly observed anti-predator strategy. Possible anti-predator benefits of aggregation include the encounter/avoidance effect for visually hunting predators and the dilution effect, together dubbed attack abatement.

We investigated maternal effects in Schizotetranychus brevisetosus (Tetranychidae), where females oviposit summer and winter eggs in response to photoperiod on evergreen hosts. Developmental rates of immature individuals increased linearly from 15°C to 35°C, but winter and summer eggs developed faster at low and high temperatures, respectively ...

Implications of new sustainable greenhouse systems for pests, diseases and biological control : a modelling approach using Oidium neolycopersici and Tetranychus urticae [PDF]
Concerns regarding carbon emissions, increasing demands on water supplies and environmental pollution have meant that the European protected horticulture industry is being challenged to develop more sustainable greenhouse climate management systems ...

A novel and versatile method is described for measuring the contact activity of acaricides against spider mites. The microimmersion (MI) bioassay involves drawing batches of 25 mites into small pipette tips under vacuum, immersing them for 30 s in 35 mul

ABSTRACT This article analyses the ‘Gestus’ of turning in films by Harun Farocki and Christian Petzold, in light of a central claim of Andrew Webber's esteemed theoretical work on film: that film has the power to uncover unconscious processes through which subjects come into being and are made operational for political regimes.

Hairy Roadblock: Stem Trichomes Impede Herbivore Movement in a Species and Instar‐Dependent Manner
ABSTRACT Plants have evolved to deploy a vast set of defence mechanisms against insect herbivores, including physical barriers like leaf trichomes with pre and post ingestive effects. Yet, the role of stem trichomes in plant‐herbivore interactions, particularly mobility dynamics, is poorly understood.

ABSTRACT With climate change, abiotic and biotic stresses such as drought and herbivory are predicted to further diminish agricultural productivity. Soybean (Glycine max [L.] Merrill), a crop of global economic importance, is vulnerable to both. However, the interactive effects of drought and herbivory on soybeans haven't been explored, especially ...

A few spider mites in soybeans
The weather in Iowa over the next several weeks will determine whether spider mites escalate to damaging levels or not. If the temperatures are cooler than normal, then spider mites would not be expected to be a problem in soybeans; however, there are a ...

Beneficial microorganisms are known to promote plant growth and confer resistance to biotic and abiotic stressors. Soil-borne beneficial microbes in particular have shown potential in protecting plants against pathogens and herbivores via the elicitation
