Cell, 2004 In this issue, Kamhawi et al. (2004) describe the identification of an insect galectin as the receptor for the stage-specific Leishmania adhesin lipophosphoglycan (LPG). This interaction is critical for parasite survival in the midgut of its sand fly vector. The results open new avenues for studies of insect immunity, transmission binding vaccines, and

Unapparent trees: escaping enemies in time by being discreet, unpredictable and inaccessible
Oikos, EarlyView.For half a century, biologists considered trees as particularly apparent to their enemies. But why then do some trees escape herbivorous enemies by bursting buds either too early or too late, leading to phenological mismatch? We hypothesize that such mismatches occur on trees that are unapparent in time – those that burst buds ‘discreetly' (slowly) and

Life history characteristics of birds influence patterns of tick parasitism
Infection Ecology & Epidemiology, 2019 Introduction: Birds serve as reservoirs for tick-borne pathogens as well as hosts for multiple tick species of public health relevance. Birds may perpetuate life cycles of vectors and vector-borne pathogens and disperse disease vectors over long ...

Harnessing entomopathogenic fungi: A meta‐analysis on their role as plant growth promoters
PLANTS, PEOPLE, PLANET, EarlyView.Our meta‐analysis highlights the potential of entomopathogenic fungi (EPF) as sustainable alternatives to chemical pesticides and fertilisers. By promoting plant growth and reducing reliance on agrochemicals, EPF can support healthier crops, minimise environmental contamination and improve profitability within food production systems.

WiSPA: A new approach for dealing with widespread parasitism [PDF]
arXiv, 2016 Traditionally, studies of coevolving systems have considered cases where a parasite may inhabit only a single host. The case where a parasite may infect many hosts, widespread parasitism, has until recently gained little traction. This is due in part to the computational complexity involved in reconstructing the coevolutionary histories where parasites

Assessing pest control treatments from phenology models and field data
Pest Management Science, Volume 81, Issue 4, Page 1851-1859, April 2025.Theoretical effect of two larvicide sprays, two delayed larvicide sprays that follow an oil treatment, mating disruption, and mating disruption plus four virus sprays on codling moth larva (brown for treated versus pink for untreated) and adult (dark green for treated versus light green for untreated) phenology.

Human anaerobic intestinal "rope" parasites [PDF]
arXiv, 2013 Human intestinal helminths are described in this paper. They can be over a meter long, with an irregular cylindrical shape, resembling a rope. These anaerobic intestinal "rope" parasites differ significantly from other well-known intestinal parasites. Rope parasites can leave human body with enemas, and are often mistaken for intestinal lining, feces ...

Indirect plant defense may provide economically important pest suppression in sorghum
Pest Management Science, EarlyView.Laboratory measures of sorghum direct and indirect plant resistance traits aligned with natural enemy recruitment and pest suppression in the field. Abstract BACKGROUND A promising strategy to optimize biological control of insect pests is selecting crop varieties with indirect defense traits.
