Romalea guttata Houttuyn (= R. microptera Beavois) is flightless, lethargic, aposematic, and chemically defended. R. guttata stores large quantities of two adipokinetic hormone (AKH) family peptides in its corpora cardiaca. In adults, these peptides (Rom-CC-I and Grb-AKH) activate fat body glycogen phosphorylase but are not hypertrehalosemic. Because juvenile R. guttata contain sufficient pepti...

OBJECTIVE To examine the prevalence of and risk factors for cornea guttata in a rural southwestern island of Japan. DESIGN Cross-sectional, population-based study. All residents of Kumejima Island, Japan, located in southwestern Japan (eastern longitude, 126° 48'; northern latitude, 26° 20'), 40 years or older were asked to undergo a comprehensive questionnaire and ocular examination, includi...

AIMS To investigate the frequency of corneal guttata in patients with a corneal dystrophy resulting from an Arg124His (R124H) mutation of betaig-h3 gene. METHODS Slit lamp examination was performed on 30 eyes with corneal dystrophy from a genetically confirmed betaig-h3 R124H mutation and on 50 age matched control eyes. The stage of the corneal dystrophy was classified as stage 0, I, or II an...

In the Mediterranean basin area, powdery mildew disease on hazelnut is commonly caused by Phyllactinia guttata. The occurs in late summer-autumn causing limited damage or economic impact. April 2021, an unusual outbreak of was observed lower leaves hazelnuts (cvs, Negret and San Giovanni) leading to rapid leaf desiccation two commercial orchards (Camí de la Serra Mas Coma), both located at La S...

PURPOSE. To devise a mathematical disease classification model for eyes with primary guttata cornea, on the bases of endothelial loss trajectory and probability of advanced disease. METHODS. A series of 1971 patients (3281 eyes), some with and some without guttata corneas, undergoing specular microscopy were retrospectively reviewed. The eyes were classified into four stages; stage 0, without g...

A BBRC review of the identification criteria of ‘Dark-breasted Barn Owls’ Tyto alba guttata concluded that only those birds with completely buff underparts were safely identifiable as guttata. Many British claims of guttata show varying amounts of white below, and are thought to originate from the wide intergrade zone between guttata and nominate alba, although variation within alba may also ac...
