Behavioural responses of peach potato aphid, Myzus persicae Sulzer (Hemiptera: Aphididae), to entomopathogenic fungi infected conspecifics

Agricultural and Forest Entomology, EarlyView.
Myzus persicae showed no detectable behavioural response to Beauveria bassiana‐colonised agar alone. Aphids spent significantly more time in odour fields containing EPF‐infected conspecifics than healthy aphids, agar or blank air. EPF infection may alter host‐associated odours, suggesting pathogen‐mediated cues could influence aphid behaviour and ...

Retinal dystrophies simulating geographic atrophy: A diagnostic challenge

Acta Ophthalmologica, EarlyView.
Abstract Geographic atrophy (GA) is the chronic loss of retinal pigment epithelium, photoreceptors and choriocapillaris, marking the dry late stage of age‐related macular degeneration (AMD). GA prevalence is expected to rise in the upcoming decades. Advanced GA leads to central scotomas, reducing visual acuity and quality of life, potentially resulting

Morphology and Chemical Characterization of the Metathoracic Scent Gland in Halyomorpha halys (Stål, 1855) (Hemiptera: Heteroptera: Pentatomidae)

Acta Zoologica, EarlyView.
ABSTRACT Halyomorpha halys (Stål, 1855) is an invasive pentatomid species causing considerable economic losses in agricultural systems. Despite the ecological importance of the metathoracic scent gland (MTG) in chemical defence and communication, detailed information on its morphology and secretion composition remains limited. In the present study, the
