Predation potential of ladybird beetle, Coccinella septempunctata (Linnaeus) (Coleoptera: Coccinellidae) against aphids infesting wheat
Keywords:
<i>Coccinella septempunctata</i>, aphids, predation potential, coccinellidsAbstract
The predation potential of grub and adult of Coccinella septempunctata (Linn.) was studied under laboratory conditions, in Department of Entomology, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, Himachal Pradesh, India. The studies revealed that the duration of the 1st, 2nd, 3rd, 4th larval stage, pupae and adult of C. septempunctata was 2.0±0.71, 4.60±0.55, 4.80±0.84, 6.00±1.58, 4.20±0.84 and 38.80±1.66 days, respectively and the aphid consumption per day was 16.00, 16.19, 21.44, 18.55 and 36.80 aphids, respectively. The total number of aphids consumed during 1st, 2nd, 3rd, 4th and adult of C. septempunctata were 33.6, 72.6, 103.0, 112.0 and 1424.6, respectively.Downloads
