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.

Effects of Phytoplasma Infection on Aster Leafhopper (Macrosteles quadrilineatus) Settling Behavior and Development on Brassica napus

Entomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 132-141, February 2026.
Aster yellows phytoplasma (AYp) infection alters host plant preference in aster leafhoppers (Macrosteles quadrilineatus), with infected vectors showing a significant preference for AYp‐infected canola (Brassica napus) early in the infection period. However, this preference fades as infection progresses. Despite early attraction, B.

An Immunodominant Membrane Protein (Imp) of ‘Candidatus Phytoplasma mali’ Binds to Plant Actin

Molecular Plant-Microbe Interactions, 2012
The phytopathogenic, cell-wall-less phytoplasmas exhibit a dual life cycle: they multiply in the phloem of their host plant and in the body of their insect vector.

Etude sur la transmission de la maladie de Cap Saint Paul du cocotier au Ghana [PDF]

, 2008
Les recherches sur le vecteur de la maladie de Cap Saint Paul du cocotier au Ghana ont débuté à partir de 1990 (90-97; 2002-04) et n'ont pas donné de résultats probants. A partir de juillet 2005, de nouvelles normes d'essais ont été appliquées: ombrière,

Leafhoppers in phytoplasma infected carrot fields: species composition and potential phytoplasma vectors [PDF]

, 2009
Aster yellows phytoplasmas (‘Candidatus Phytoplasma asteris’, AY) have a wide host range and are transmitted in a persistent manner by Phloem - feeding leafhoppers and planthoppers (Hemiptera: Auchenorrhyncha). Recently, aster yellows phytoplasmas have been "eported for the first time in carrot fields in Serbia (Duduk et al., 2007).

Possible insect vectors of ‘Candidatus Phytoplasma asteris’ and ‘Ca. Phytoplasma pruni’-related strains in Lithuania [PDF]

Zemdirbyste-Agriculture, 2014
Phytoplasma strains affiliated with groups 16SrI, 16SrIII, 16SrV and 16SrXII have been found in Lithuania, but their insect vectors in the country have not been determined. ‘Candidatus Phytoplasma asteris’ and ‘Ca. Phytoplasma pruni’-related phytoplasma strains were identified in five leafhopper species and three spittlebug species occurring in ...
