Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

open access: yesInsect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Maltase 1 regulates DENV2 infection and life history in Aedes aegypti

open access: yesInsect Science, EarlyView.
Our study employed CRISPR/Cas9 to generate a MAL1 knockout strain of Aedes aegypti, demonstrating that the absence of MAL1 significantly suppresses DENV2 replication in the midgut and impairs viral transmission. The mutation also altered life‐history (hatching/pupation/emerging rates and sex‐specific survival), identifying MAL1 as a novel target for ...

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

open access: yesInsect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

Males are worse mothers: Comparing care patterns in a facultatively caring beetle

open access: yesInsect Science, EarlyView.
Why should biparental care exist if offspring fare just as well when only one parent is present? In the facultatively dependent burying beetle, Nicrophorus vespilloides, manipulating environmental quality reveals that biparental care benefits offspring in form of lower personal immune requirement and parents in term of weight gain.

Reconsidering the importance of Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) as a crop pest

open access: yesAgricultural and Forest Entomology, EarlyView.
Four‐year field monitoring and laboratory studies revealed M. dirhodum occurs regularly in barley with high reproductive potential and extended adult longevity. Populations peaked during vulnerable crop stages, creating optimal conditions for BYDV transmission during critical infection windows. M.

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 1. Methods to Improve Insect Collection and Parasitoid Pupariation

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We describe methods for collecting and rearing the tachinid parasitoid Istocheta aldrichi from parasitized Japanese beetle adults. Hosts can be collected by hand and reared in the laboratory, or by using modified trap containers with added plant material and substrate to provide suitable conditions for I.

Ontogenia temprana de Poblana letholepis (Actinopterygii: Atherinopsidae)

open access: yesRevista Mexicana de Biodiversidad, 2016
Poblana letholepis es endémica del lago cráter La Preciosa, Puebla. La especie está amenazada debido a que su hábitat se encuentra bajo desecación por la deforestación, el sobrepastoreo y malas prácticas de riego.
