Abstract
The impact of healthy aphids, BYMV viruliferous aphid on faba
bean plants, and the combined effect by releasing Chrysopa carnea
larvae was tested during the stages of plant development: seedling
stage, flowering stage and the podsiting stage. The parameters of the
treatment evaluation were the number of seeds/pod, the number of
seeds/plant, the weight of seeds/plant and the weight of 100 seeds. No
obvious effect was observed on the number of seeds per pod among all
treatments. The effect of the virus infected aphids was drastic on the
infected plants. The release of Chrysopa larvae on the infected plants
(either by healthy or by viruliferous aphid) was significant in increasing
the number and weight of seeds whatever the stage of plant
development. The release of C. carnea has to be carried out in the early
phonological stage of the plants, as soon as aphids appear in order to
prevent virus infestation.
