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

open access: yesPest 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.

Sex Pheromone of the Papaya Mealybug [PDF]

open access: yesJournal of Chemical Ecology
Sex pheromones of mealybugs are reported from more than 20 species and have generally been shown to be monoterpene alcohols esterified with short-chain carboxylic acids. Here, however, we discovered and isolated an alcohol without an acid moiety as a pheromone compound released from adult females of the papaya mealybug, Paracoccus marginatus.

The Association Between Basidiomycete Fungi and Mealybugs Pseudococcidae Affects Coffee Plants

open access: yesAgronomy
Some Pseudococcidae species interact with Coffea arabica’s roots and are associated with basidiomycete fungi. The fungal mycelium envelops the roots, which hinders their water and nutrient absorption.
