The aim of the investigations was to determine the effect of interaction between individual aphidophagous groups and their developmental stages on their occurrence in Aphis fabae Scop. colonies in…
Colonization of apple orchards by predators of Dysaphis plantaginea: sequential arrival, response to prey abundance and consequences for biological control

The results of this study indicate that natural populations of syrphids and ladybird beetles are unable to control D. plantaginea, and therefore a more complex strategy than waiting for natural enemies is required.
Oviposition behaviour and host colony size discrimination in Episyrphus balteatus (Diptera: Syrphidae)
- BiologyBulletin of Entomological Research
- 2001
Three bioassays were used to examine the oviposition behaviour of the hoverfly, Episyrphus balteatus (Degeer) in which various stimuli purported to influence host assessment and choice were tested, suggesting that females are merely responding to the colour of the artificial leaves.
