Effect of introduction of Chrysoperla carnea (Steph.) on certain soybean-yield parameters of SbMV-infected plants by using viruliferous Aphis craccivora Koch [electronic resource].

Includes reference.

Isolation of soybean mosaic virus (SbMV) was carried out by Indirect ELISA method to detect local isolate (from Minia Governorate) of SbMy in soybean infected plants. The impact of healthy aphids, SbMV-viruliferous aphids on soybean plants, and the combined effects by releasing Chrysoperla carnea Stephens larvae were tested during three different stages of plant development. Parameters of treatment evaluation were the number of seeds/pod, seeds/ plant, weight of seeds/ plant and weight of 100 seeds. No obvious effect was observed on the number of seeds per pod among all treatments. The effect of viruliferous aphids was drastic on the treated plants.
