Tiny predators avoid herbivorous caterpillar traces to prevent accidental predation

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract We report the first example of predators having a strategy to avoid accidental predation by herbivorous insects. The predatory mites Neoseiulus womersleyi and Euseius sojaensis are smaller than 0.5 mm and lay eggs on plant leaf surfaces; thus, their immobile eggs would be incidentally consumed along with leaves by voracious lepidopteran ...

Survey of Poncirus trifoliata Hybrids for Resistance to Colonization by Asian Citrus Psyllid [PDF]

Florida Entomologist, 2019
Genetic traits in Poncirus trifoliata (Rutaceae) are known to confer resistance to colonization by the Asian citrus psyllid, but field surveys indicated these traits were not expressed in any of 24 simple hybrids between P. trifoliata and sweet orange. No resistance to colonization by the psyllid was observed in 14 other types of P. trifoliata hybrids.

Natural variation links seedling hypocotyl growth with water loss in Arabidopsis

The Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Plants integrate environmental and internal cues such as light and sugar availability to coordinate growth and water‐use strategies. While hypocotyl elongation is widely used to study photo‐ and thermo‐morphogenesis, its connection to whole‐plant physiological traits remains unclear.

A Systematic Approach to Field Testing of Biological Products for Horticulture Is Required to Improve Food Security

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Food security challenges require immediate action to increase food production. Many biological products derived from plant, animal or microbial sources claim they sustainably increase yield, but there are concerns about biosecurity to be investigated before their introduction to the field.

High Environmental Irradiance Induces Anatomical and Ultrastructural Damage in Citrus Leaves

Physiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Climate change is intensifying episodes of high irradiance and thermal stress, posing a major threat to the sustainability of citrus production. Although reflective particle films have emerged as mitigation tools, their protective effects at the anatomical and ultrastructural levels under field conditions remain insufficiently understood. Here,
