Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

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.

The green peach aphid, Myzus persicae, is the main virus vector in sugar beet. We examine its performance on potential winter hosts as well as the host selection and overwintering success of anholicyclic aphids in order to improve forecasting models for virus outbreaks through targeted monitoring of suitable winter hosts. Abstract Virus yellows (VY) is

Nymphal development took longer at 25°C than 30°C, and the Greek N. tenuis population developed more slowly than the commercial population. Nymphs clearly preferred E. kuehniella eggs over Artemia sp. cysts when both were offered equally. Egg production increased at 30°C, while female longevity declined.

We used automated activity monitors to examine how light‐emitting diode illumination affects the daily locomotor activity of the parasitoid biocontrol agent Aphidius matricariae. We compared 4‐ to 20 h broad‐spectrum white (BSW) photoperiods, and 12 h BSW photoperiods extended with an additional 6 h of red‐blue, red‐green‐blue, or BSW light, or no ...
