CORN LEAFHOPPER (Dalbulus maidis): PHYTOSANITARY IMPORTANCE, EPIDEMIOLOGY, AND MANAGEMENT

Artefactum - revista de estudos interdisciplinares
The corn leafhopper, Dalbulus maidis, is one of the most important phytosanitary constraints in maize production systems across the Americas due to its role as the primary vector of the corn stunt disease complex. This review synthesizes current knowledge on the phytosanitary importance, epidemiology, and management of D.

‘Candidatus Liberibacter Asiaticus’ Effector SECP8 Subverts Salicylic Acid‐Mediated Citrus Immunity via a Two‐Pronged Impairment of CsTCP15 Dimerization

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2335-2349, April 2026.
ABSTRACT Citrus Huanglongbing (HLB), a devastating disease caused by the unculturable bacterium ‘Candidatus Liberibacter asiaticus’ (CLas), poses a severe threat to global citrus production. CLas secretes effectors to suppress host immune responses and facilitate its colonisation. Previously, the CLas effector SECP8 (CLIBASIA_05330) has been identified

Molecular polymorphisms that underlie trait variation in crops: Lessons learned from soybean

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Genetic variation within a germplasm is important in crop improvement, providing a foundation for breeders to develop new varieties. Traits of agronomic and economic importance are often mapped to identify the genetic basis of observed phenotypes, oftentimes using quantitative trait locus (QTL) analysis.

Jujube Witches' Broom Phytoplasma Effectors SJP1/2 Manipulate the ZjTCP2‐ZjTCP1 Cascade to Repress Leaf Cell Proliferation in Jujube

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.
SJP1 and SJP2, two effectors secreted by JWB phytoplasmas, inhibit jujube leaf cell proliferation through manipulating a cascade involving ZjTCP2 and ZjTCP1, two TCP transcription factors from distinct subfamilies. ABSTRACT Leaf development into the final size is spatiotemporally regulated by cell proliferation and expansion. The jujube witches' broom (

Molecular, morphological, and biological differentiation between Anagrus virlai sp. n., an Egg parasitoid of the Corn Leafhopper Dalbulus maidis (Hemiptera: Cicadellidae) in the New World, and Anagrus incarnatus from the Palaearctic region (Hymenoptera: Mymaridae). [PDF]

, 2018
The common New World egg parasitoid of the corn leafhopper Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae), an economically important pest of maize from Argentina to southern USA, has long been misidentified as the Palaearctic species Anagrus ...

The Vulnerability of New Zealand Forage Plants to Incursions by New Pests, Pathogens and Weeds, and the Case for Greater Protection

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.
