| Summary: | Considering the potentiality of farmscaping on the diversity of major pestiferous insect and their natural enemies, present study was conducted at field level in randomized block design with farmscape treatments comprised of intercropping cabbage with coriander, onion, mustard, marigold; mustard as trap crop and cabbage sole was taken as control for comparison. The major pestiferous insects were aphid, diamond back moth, tobacco caterpillar painted bug and flea beetle who attained the pest status during the crop season. Associated key natural enemies included aphidiphagous coccinellids, syrphid flies and aphid parasitoids which were observed. The Shannon diversity (H’) index for key pestiferous insects was maximum on sole cabbage (0.75), while minimum in cabbage + mustard as trap crop (0.5). Maximum pooled seasonal population mean of major natural enemies was recorded in farmscaping treatment possessing cabbage + coriander (2: 1) with mummified aphids (36.03/plant) and relative density of 89.36 per cent; coccinellids (1.34/plant) with relative density of 3.31 per cent and syrphid fly larvae (2.96/plant) having a relative density of 7.33 per cent. |
