Lethal Effects of the Wild Potato Solanum bulbocastanum on the Planthopper Pentastiridius leporinus, a Vector of Bacterial Pathogens in Potato

Journal of Applied Entomology, Volume 150, Issue 6, Page 756-769, July 2026.
ABSTRACT The planthopper Pentastiridius leporinus [Hemiptera: Cixiidae] is a vector of the two plant pathogenic bacteria ‘Candidatus Arsenophonus phytopathogenicus’ and ‘Candidatus Phytoplasma solani’ causing ‘bacterial potato tuber wilt’ in potato.

Synthetic Ligands of Olfactory Binding Proteins Modulate Aggregation Response of Asian Citrus Psyllid in the Presence of Host-Plant Volatiles

Frontiers in Plant Science, 2018
There is interest in using ligands of chemosensory binding proteins (CBP) to augment an insect’s responsiveness to chemosensory cues. We showed previously that combining a synthetic ligand of a CBP with limonene, a common citrus volatile, enhanced the ...

Widespread Lateral Transmission in Fergusonina Galling Flies (Diptera: Fergusoninidae) and Their Obligate Nematode Mutualists Does Not Preclude an Overall Pattern of Cospeciation

Ecology and Evolution, Volume 16, Issue 6, June 2026.
The biology of gall‐forming fergusoninid flies and their obligate nematode mutualists suggests strict vertical transmission of nematodes between fly generations. Using mitochondrial sequence data to associate fly and nematode haplotypes, we found widespread intraspecific horizontal transfer in multiple species.

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

Pest Management Science, Volume 82, Issue 6, Page 5184-5194, June 2026.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Diversification of Legume-Feeding Psyllids (Hemiptera, Psylloidea) and Their Host Plants (Leguminosae, Genisteae) [PDF]

, 2001
Psyllids ('jumping plant lice') are small phytophagous insects that are related to aphids, scales and whiteflies (Hemiptera, sternorrhyncha). Psyllids are highly host specific, occurring on one or a few closely related hosts, and they predominantly feed ...

Waggle movement as a visual mate-finding signal in Triozid psyllids [PDF]

, 2019
Three species of psyllids within Triozidae have been recorded to exhibit a wagging or twitching movement of their abdomens. Here, I present video of one of these species.

Parasitoid shows potential for biocontrol of eugenia psyllid

California Agriculture, 1995
The eugenia psyllid has become a major pest of eugenia, a commonly used ornamental plant in the coastal counties of California. Attempts to control this insect with insecticides have been only partially successful.

Innate and Conditioned Responses to Chemosensory and Visual Cues in Asian Citrus Psyllid, Diaphorina citri (Hemiptera: Liviidae), Vector of Huanglongbing Pathogens

Insects, 2014
Asian citrus psyllid (Diaphorina citri) transmits Huanglongbing, a devastating disease that threatens citrus trees worldwide. A better understanding of the psyllid’s host-plant selection process may lead to the development of more efficient means of ...

Asian citrus psyllid stylet morphology and applicability to the model for inter-instar stylet replacement in the potato psyllid

Arthropod Structure & Development, 2018
In Hemiptera, presumptive stylets for each consecutive postembryonic instar are manufactured prior to ecdysis to replace the ecdysial stylets discarded with the exuviae. With the discovery that the bacterium "Candidatus" Liberibacter solanacearum accesses the tissues involved in the stylet replacement process of the potato psyllid, a hypothesis was ...
