Abstract:

This study evaluates the average consumption rates of biological control agents of wheat aphids in wheat crops during the Spring of 2021-2022. Two experiments were conducted i.e one under field conditions and another under laboratory conditions. In the field experiment, Chrysopa Mature Larva exhibited the highest average consumption rate, followed by Ladybird Beetle (LBB) Mature Larva. In the laboratory experiment, Chrysoperla carnea (C. carnea) adult stages showed relatively higher consumption rates compared to LBB adult stages. Combining C. carnea adult stages with LBB adult stages resulted in the highest average consumption rate among all treatments. These findings provide valuable insights into the effectiveness of different predator species and stages in controlling wheat aphid populations, informing the development of integrated pest management strategies for sustainable agriculture.

Keywords: Bio control, wheat aphids, predators, integrated pest management, consumption rates.
