Abstract

The efficiency of three Coccinellidae species against Brevicoryne brassicae (L.) (Homoptera: Aphididae) in cabbage fields were carried out at El-Behiera Governorate, Egypt in tow successive season during the period from 4th August to 27th October, 2017 and 2018. When Coccinella septempunctata was released with 100 adults/ 1000 plants, the general mean number of B. brassicae was 29.24 and 31.96 in season 2017 and 2018, respectively. On the other hand, releasing C. septempunctata with 500 adults/ 1000 plants decreased the general mean number of B. brassicae by 13.16 and 13.86 in season 2017 and 2018, respectively. In season 2017, when 100 adults of C. undecimpunctata were released at the beginning of the study the population increased after four weeks recording 0.25 adult individual / plant. Meanwhile when 500 C. undecimpunctata were released in the same season, the population increased gradually and recorded the highest number at the end week of the study period. The Population fluctuations of S. interruptus did not affect the density of B. brassicae as well as the adult predator released. Number of B. brassicae increased gradually in season 2017 recording the highest number of 148 individuals/ plant.
