From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

Insect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

RNAi‐based functional genomics tools for the beet leafhopper using microinjection and nanoparticle‐based topical spray

Insect Science, EarlyView.
• First demonstration of functional RNAi in the beet leafhopper, Neoaliturus tenellus, using both dsRNA microinjection and star polycation nanoparticle‐mediated topical spray delivery.•Microinjection achieved over 90% knockdown of Gus and Pum3, revealing gene‐specific fitness effects on survival and fecundity in beet leafhopper.•Nanoparticle‐mediated ...

Taxonomic evaluation of three Egyptian Solanum species based on morphology, DNA sequences, and chromosome analysis

Caryologia
We investigated the intra-specific relationships between three Solanum species in Egypt: Solanum nigrum, Solanum villosum, and Solanum sinaicum, in addition to the inter-specific relationships among the populations of the three studied species.

Responses of Soil Arthropod Communities to Varying Shading Levels in Agriphotovoltaic Systems

Integrative Zoology, EarlyView.
Soil fauna was primarily influenced by crop type and season rather than AgriPhotovoltaic (APV) panels. Elevated panels increased soil temperature and soil organic matter in early wheat stages, while shading enhanced soil moisture for tomatoes, benefiting moisture‐sensitive taxa.

Biology, ecology and dynamics of Deborrea malgassa (Heylarts 1884) (Lepidoptera: Psychidae), the main threat to apple Malus domestica Borkh growing in Madagascar

Agricultural and Forest Entomology, EarlyView.
Bioecology parameters of the endemic Psychidae Deborrea malgassa, the main pest of apple trees in Madagascar. Spatiotemporal dynamics of Deborrea malgassa, with a peak infestation between May and August. Proposed targeted prophylaxis techniques associated with other agroecological principles will be key to reducing the vulnerability of apple orchards ...
