An RNA interference biopesticide reduces reproduction of the honey bee parasite Varroa destructor by down‐regulating embryo development pathways

open access: yesPest Management Science, EarlyView.
Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...

Preference of red mite Tetranychus ludeni Zacher (Acari: Tetranychidae) to sweet potato genotypes

open access: yesBrazilian Journal of Biology, 2018
Tetranychus ludeni damages the sweet potato. Pest development can vary between plant genotypes. The objective was to identify the preference of Tetranychus ludeni for Ipomoea batatas genotypes, from the germplasm bank at the Universidade Federal dos ...

Comparison of synthetic membranes in the development of an in vitro feeding system for Dermanyssus gallinae [PDF]

open access: yes, 2010
Although artificial feeding models for the poultry red mite (Dermanyssus gallinae) most frequently use biological membranes consisting of day-old chick skin, there are ethical considerations associated with the use of skin.

Impacts of rodents in piggeries in Australia – review and pilot impact study

open access: yesPest Management Science, EarlyView.
Rodent impacts in Australian piggeries are under‐researched, with limited data on economic losses and control costs. A review and pilot study found average losses of AUD$100 000 annually. Key concerns include disease, damage, and control expenses.

Concurrent Parasitism Alters Thermoregulation in Honey Bee (Hymenoptera: Apidae) Winter Clusters [PDF]

open access: yes, 2017
Thermoregulation is crucial for honey bee, Apis mellifera L. (Hymenoptera: Apidae), colony survival in temperate regions, but possible interference by parasites is currently unknown. The small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae),

Evolving resistance patterns in Tetranychus urticae and Bemisia tabaci in Greece

open access: yesPest Management Science, EarlyView.
Greek populations of T. urticae and B. tabaci exhibit evolving multi‐resistance, confirmed by bioassays and molecular markers, highlighting the urgent need for evidence‐based resistance monitoring in IPM. Abstract BACKGROUND Pesticide resistance in agricultural pests remains a major barrier to effective and sustainable crop protection.

Molecular Assessment of Genes Linked to Immune Response Traits of Honey Bees in Conventional and Organically Managed Apiaries

open access: yesInsects, 2020
Honey bees are of great economic importance, not only for honey production but also for crop pollination. However, honey bee populations continue to decline mainly due to exposure to pesticides, pathogens and beekeeping practices.

Selective leaf surface defenses: trichomes trap herbivorous leafminers but spare parasitoid wasps

open access: yesPest Management Science, EarlyView.
Hooked trichomes on kidney bean leaves selectively entrap leafminer flies but rarely affect parasitoid wasps. This morphological barrier enables pest suppression with minimal impact on beneficial insects, offering insights for breeding pest‐resistant cultivars compatible with biological control. Abstract BACKGROUND Leafminers [e.g., Liriomyza trifolii (
