Eco feast crops has roots in traditional forms of mixed farming systems for pest management, but in the context of industrialized agriculture, has been actively pursued under the terms ‘habitat management/manipulation’and ‘conservation biological control’for only a few decades. These crops could serve as an environment friendly ecological control servicesto suppress crop pests and reduce pesticide use by preserving or enhancing natural enemies as they have a great influence on natural enemy longevity, fecundity and behaviour. The experiments were conducted during kharif 2022-23 and 2023-24 in the University of Agricultural Sciences, Dharwad to evaluate the feasible eco feast crops like maize, sorghum, buckwheat, cowpea, niger, onion, coriander and sunflower by adjusting their sowing dates to ensuresynchronizedfloweringperiodacrossthe crops.Their performance wasassessedbased on the natural enemy data collected on the population of predators and parasitoids during the floweringperiodofboth seasons.Further,theselectedecofeastcrops viz., maize,cowpea and buckwheat were assessed as strip, border and inter crops in Bt cotton to know their influence on the sucking pest incidence on cotton by way of attracting natural enemies and thereby reducing the pest population on cotton.Among the different eco feast crops evaluated for their performance during 2022-23 and 2023-24, buckwheat followed by sunflower and maize were found to attract large population of different predators and parasitoids. The population of predators such as spiders, coccinellids, lace wings and syrphids as well as the sucking pests like leaf hopper andwhitefly were recorded on cotton at frequent intervals. The leaf hopper and whitefly population was significantly low in all combination treatments as compared to control (sole cotton). Among different eco feast crops, buckwheat followed by cowpea and maizesupportedthehighestnumberofnaturalenemies comparedto controlinboththeseasons.The biochemical analysis of all the eco feast crop flowers revealed that highest quantity of Total Soluble Sugars (708.043 µg/100g) and Total Reducing Sugars (198.657 µg/100g) was recorded in buckwheat compared to cowpea, maize and cotton which could be considered as the main factor influencing high density of predators, parasitoids and pollinators on the buckwheat inside cotton ecosystem.Efficiency of buckwheat in different pest management systems of Bt cotton indicated that buckwheat as an intercrop or border crop was found effective in management of sucking pests ofcotton.Amongthedifferent farmingmodules, with thelowest suckingpest incidence, chemical farming of cotton with buckwheat was as effective as IPM of UASD followed by organic farming of cotton with buckwheat as eco feast crop. The highest Simpson diversity index and Shannon diversity index were however recorded in the natural farming module followed by organic and IPM modules. Thus, the findings support promotion of eco feast crops in Bt cotton ecosystem to manage sucking pest menace. Cotton-based intercropping systems are important for farmers predominantly with small land holdings. These systems are feasible and involve inter crops intensively to use resources more effectively, resulting in improved productivity.
