Ferrisia gilli(Hemiptera: Pseudococcidae) Transmits Grapevine Leafroll-Associated Viruses [PDF]

Journal of Economic Entomology, 2016
Several mealybug species are vectors of grapevine leafroll-associated viruses (GLRaV), which cause the economically important grapevine leafroll disease in grape-producing regions worldwide. The mealybug Ferrisia gilli Gullan is a new pest of grapevines in El Dorado County, located in the Sierra Foothill wine-growing region of California. GLRaV species

Contrasting Evolutionary Trajectories Under Paternal Genome Elimination in Male and Female Citrus Mealybugs. [PDF]

Mol Ecol
ABSTRACT Most studies of sex‐biased genes explore their evolution in familiar chromosomal sex determination systems, leaving the evolution of sex differences under alternative reproductive systems unknown. Here we explore the system of paternal genome elimination employed by mealybugs (Hemiptera: Pseudococcidae) which have no sex chromosomes.

“Alien versus predator”: predatory effect of coccinellid Exochomus quadripustulatus on the scale insect Toumeyella parvicornis. An open‐field experimentation on the Pinus pinea of Rome

Insect Science, EarlyView.
The release of gravid Exochomus quadripustulatus females proved to be effective in containing Toumeyella parvicornis infestations on stone pine trees, under open‐field condition. The ladybugs caused a lower infestation level compared to the trees that did not receive any ladybugs during the observation season.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, EarlyView.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

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.

First report in Italy of Thrips parvispinus (Karny, 1922) (Thysanoptera, Thripidae), a major threat for Sicilian horticulture and floriculture

EPPO Bulletin, Volume 56, Issue 1, Page 130-137, April 2026.
Abstract The presence of Thrips parvispinus (Karny, 1922) is reported for the first time in Italy. Prior to this finding, within Europe the pest was only known to be established in Spain. The discovery happened in a greenhouse cultivating gerberas in south‐eastern Sicily, a region recognized as Italy's primary and one of Europe's most important ...
