Efficacy of Zeolite and Kaolin in the Control of Cacopsylla pyri (L.) (Hemiptera: Psyllidae) and Compatibility With Its Natural Antagonist Anthocoris nemoralis (Fabricius) (Hemiptera: Anthocoridae)

Journal of Applied Entomology, Volume 150, Issue 8, Page 1080-1087, September 2026.
ABSTRACT The pear psyllid Cacopsylla pyri is a major pest of European pear orchards, responsible for significant yield losses. Its management is increasingly challenged by restrictions on synthetic active ingredients, resistance development, and the shift towards sustainable production systems.

Surveys reveal the occurrence of phytoplasmas in plants at different geographical locations in Peru

, 2009
Two independent surveys were performed in Peru during February and November 2007 to detect the presence of phytoplasmas within any crops showing symptoms resembling those caused by phytoplasmas.

The pathogenic effector PHYL1JWB interacts with ZjCURT1A to mediate jujube witches' broom‐induced photosynthesis impairment of jujube trees

The Plant Journal, Volume 127, Issue 5, September 2026.
SUMMARY Photosynthesis impairment and the accompanying leaf yellowing represent a prominent and physiologically critical symptom of phytoplasma infection. However, the underlying molecular mechanisms remain poorly understood. In this study, we identified the Jujube Witches' Broom pathogenic effector PHYL1JWB, which was previously reported to induce ...

Detection and differentiation of African coconut phytoplasmas: RFLP analysis of PCR-amplified 16S rDNA and DNA hybridisation

, 1997
Phytoplasmas associated with lethal decline diseases of the coconut palm (Cocos nucifera) in west and east Africa were detected by the specific amplification of their 16S rRNA genes. The primers used were based on conserved mollicute-specific and coconut-

Screening potential insect vectors in a museum biorepository reveals undiscovered diversity of plant pathogens in natural areas

Ecology and Evolution, 2021
Phytoplasmas (Mollicutes, Acholeplasmataceae), vector‐borne obligate bacterial plant parasites, infect nearly 1,000 plant species and unknown numbers of insects, mainly leafhoppers (Hemiptera, Deltocephalinae), which play a key role in transmission and ...

Multilocus sequence typing of diverse phytoplasmas using hybridization probe-based sequence capture provides high resolution strain differentiation

Frontiers in Microbiology, 2022
Phytoplasmas are insect-vectored, difficult-to-culture bacterial pathogens that infect a wide variety of crop and non-crop plants, and are associated with diseases that can lead to significant yield losses in agricultural production worldwide ...

A Virus‐Inducible E3–RLCK–MADS Module Coordinates Suppression of Plant Immunity and Fertility in Rice

Advanced Science, Volume 13, Issue 41, 22 July 2026.
ABSTRACT Viruses often hijack host developmental programs to promote infection, but the mechanistic links between reproductive regulation and antiviral immunity remain incompletely understood. Here, we identify a virus‐triggered hierarchical degradation cascade that links antiviral immunity and fertility regulation in rice. We show that the rice grassy

Phytoplasmas of peach and cherry.

, 2008
Recent researches show the presence In Italy in cherry of phytoplasmas of 16SrIII group in some of the samples from plants recently imported from California (Paltrinieri et al., 2001), while in peach no clear relationship was detected among symptoms ...

Dramatic transcriptional changes in an intracellular parasite enable host switching between plant and insect. [PDF]

PLoS ONE, 2011
Phytoplasmas are bacterial plant pathogens that have devastating effects on the yields of crops and plants worldwide. They are intracellular parasites of both plants and insects, and are spread among plants by insects.
