the asiatic citrus psyllid, diaphorina citri kuwayama (hom.: psyllidae), is one of the most important pests on citrus in tropical and subtropical asia. it was detected in iran during the recent years and distributed in some parts of hormozgan and sistan-baluchestan provinces. during the survey carried out to determine natural enemies of this psyllid, a nymphal parasitoid wasp was identified as ...

Beginning in 1993, Florida’s citrus industry has been invaded by citrus leafminer (Phyllocnistis citrella Stainton, Lepidoptera: Gracillariidae), brown citrus aphid (Toxoptera citricida Kirkaldy, Homoptera: Aphididae), and the Asian citrus psylla (Diaphorina citri Kuwayama, Homoptera: Psyllidae). The source(s) of these pests remain unknown but other countries in the Caribbean, as well as Centra...

Xanthomonas citri subsp. citri (Xcc) is a bacterial pathogen that causes citrus canker in susceptible Citrus spp. The Xcc genome contains genes encoding enzymes from three separate pathways of trehalose biosynthesis. Expression of genes encoding trehalose-6-phosphate synthase (otsA) and trehalose phosphatase (otsB) was highly induced during canker development, suggesting that the two-step pathw...

ABSTRACT Eradication of Asiatic citrus canker (ACC) has become increasingly difficult over the last decade, following the introduction of the Asian leafminer into Brazil and Florida, which has led to changes in the eradication protocols. The present study, undertaken in Brazil, was aimed at characterizing the spatial patterns of ACC in commercial citrus plantings to gain better understanding of...

In recent years, image processing and deep learning have been widely used in the detection classification of plant diseases. These uses offer great opportunities for early diseases agriculture. Early disease is essential to prevent symptoms from spreading intact leaves reduce crop damage. For stated reasons, a model with three different approaches has proposed that are most common citrus affect...

Bacterial type III secretion systems deliver protein virulence factors to host cells. Here we characterize the interaction between HrpB2, a small protein secreted by the Xanthomonas citri subsp. citri type III secretion system, and the cytosolic domain of the inner membrane protein HrcU, a paralog of the flagellar protein FlhB. We show that a recombinant fragment corresponding to the C-terminal...
