Abstract EN
Abundance and fluctuation of Rhopalosiphum maids (Fitch) (Hemiptera: Aphididae ) and its predatory insects was studied on both sorghum (Sorghum bicolor L.), maize (Zea mays L.) and their intercropping of both crops related weather factor through the two plantation dates of 15th June and 15th July for the two successive seasons of 2019 and 2020, respectively.
Regression and correlation analysis between the aphid and predator densities were carried out.
Nine predacious species were collected from corn fields, these species included: Four coleopterous, i.e.
Coccinella undecimpunctata.
(L.) , Scymnus pallidivestis Mulsant, Stethorus gilvifrons Mulsant (Coccinellidae) and Paederus alfierii Koch (Staphylinidae), two hemipterous Orius albidipennis (Reuter) and O.
laevigatus Fieber (Anthocoridae), dipteran syrphid hover flies, Xanthogramma aegyptium Wied.
and Sphaerophoria flavicauda Zett.
(Syrphidae) and Neuropteran Chrysoperla carnea (Stephens) (Chrysopidae).
