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.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Degree of insecticide exposure and access to nectar impact survival of Trissolcus japonicus, a hymenopteran parasitoid, in flowering border strips

Agricultural and Forest Entomology, EarlyView.
We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,
