Aphids, Peas, Predator, Pesticides, Pisum sativum, Triticum aestivum


Push-pull strategy in integrated pest management (IPM) is employed for controlling aphid population as the aphid produces deleterious damage to crops. For wheat aphid management, wheat (Triticum aestivum) and peas (Pisum sativum) were scrutinized to observe pest and predator population and peas act as the stimuli that allure the aphids (pull). In this study the pea-wheat trap crop area was divided into control (pea and wheat) and experimental (wheat sandwiched between peas) zones with an area of 0.13 acres (0.0526 hectare). The purpose was to determine natural abundance of Aphids in peas and wheat, Population abundance of natural enemies attacking aphids in peas and wheat and comparison of abundance of natural enemies and aphids in peas and wheat. Pea-wheat trials were surveyed on a weekly basis by visual observation utilizing five fixed sampling methods. Results indicated the mean number of aphid population was 54.77 in wheat control zone while in experimental zone 63.79 per 100 tillers while predators in experimental zone were 767.72 and control had 82.99 per 100 tillers. Moreover, peas considered as pull had an aphid population in control zone was 937.83 and experimental had 1147.56 per 100 plants whereas, predator in control was 33.50 and in experimental 8.66 per 100 plants. The research findings statistically showed that the population abundance of predators was 8.66 in the experimental zone for peas and 82.99 in wheat, attacking aphids in the peas and wheat ecosystem. The population abundance of predators was determined in peas and wheat, with the higher population observed in wheat compared to the peas. Thus, it can be concluded peas proved beneficial in reducing aphid population from main crop without aid of pesticides, on the basis of present research underpin the existing knowledge on Trap crop in IPM.
