Relative abundance of predatory coccinellids on oliferous Brassica.

Abstract

The relative abundance of predatory coccinelids in cultivars of Brassica juncea (RH 30, RH 9304, RH8701, RH 7846, Varuna, Purple Mutant, JMM 927 and Pusa Bold), B. rapa [B. campestris] (YSPB 24 and BSH 1), B. carinata (HC 9605) and Eruca sativa [E. vesicaria] (T 27) was investigated in Haryana, India. Coccinella septempunctata was the most abundant (57%), followed by Cheilomenes sexmaculata (21.5%) and Coccinella transversalis (20.8%). Coccinella septempunctata relative abundance was maximum (65.3%) in RH 8701 and minimum (50.05%) on HC 9605. Cheilomenes sexmaculata (27.56%) was maximum on JMM 927 and minimum (15.57%) on HC 9605. Coccinella transversalis was maximum (34.43%) on HC 9605, and minimum (17.58%) on HNS 9605.
