Efficacy of cinnamon oil and its active ingredient (cinnamaldehyde) on the cotton mealy bug Phenacoccus solenopsis Tinsley and the predator Chrysoperla carnea

open access: yesBulletin of the National Research Centre, 2020
Background The importance of Chrysoperla carnea (Steph.) (Neuroptera: Chrysopidae) as a predator is due to nourishing this predator on some dangerous pests as the cotton mealybug, Phenacoccus solenopsis Tinsley, belongs to Hemiptera: Pseudococcidae.

Climate Change Drives the Distribution of Insect Vectors for GLRaV‐3 on a Global Scale

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
The distribution range of seven insect vectors of GLRaV‐3 were predicted by MaxEnt model. Thermal conditions were a vital factor constraining the potential distribution ranges of all vector insects. Centroid shifts suggested that the potential distribution range of soft scale will move northward under climate change. Our study provides implications for

“The Last of Them”: Entomopathogenic Effect of Akanthomyces muscarius on the Scale Insect Pest Toumeyella parvicornis Under Laboratory Conditions, a Potential Biological Control Candidate

open access: yesPhysiologia Plantarum, Volume 177, Issue 5, September/October 2025.
ABSTRACT Entomopathogenic fungi are valuable alternatives to traditional agrochemicals, providing more sustainable crop protection. Akanthomyces spp. is acknowledged in biocontrol practices, especially in controlling aphids, thrips, whiteflies, and mites; however, its efficacy on soft scale insects is still poorly known.

Positive Selection Drives Mitochondrial Gene Rearrangement in Sternorrhyncha (Insecta: Hemiptera)

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
We have constructed the largest mitochondrial dataset for Sternorrhyncha to establish phylogenetic relationships. The mitochondrial genes of Coccoidea and Aleyrodoidea exhibit a notable prevalence of translocation and a high proportion of positive selection pressures.
