Crop diseases lead to significant losses in food production and economies. Crops are not food for human and animal consumption alone but also for a host of microbial pathogens and insect pests such as aphids. Researchers often study the impact of one pathogen on a particular plant species in isolation instead of considering other pathogens that share the environment. Somehow, agroecological zones support conditions favoring other pathogens and their vectors, which considerably clouds the ability to properly attribute crop losses to disease and target resources for resistance, especially concerning pesticide use. This study briefly describes biological resistance against aphids, being the major vectors of barley yellow dwarf virus (BYDV), a viral pathogen of great economic importance on wheat and barley. Adult and nymphal aphids weaken the plants by having their mouthparts inserted to withdraw plant cell sap. The infested plants develop pale silky leaves, eventually wilting. By excreting honeydew, aphids stimulate sooty mold growth on leaves that hinders photosynthesis. The biological control agents counteract these pests. Ladybird beetles (Coccinellidae), are part of the diverse biocontrol agents occurring throughout the terrestrial ecosystems. The beetles, part of the order Coleoptera, suborder Polyphaga, superfamily Cucujoidea, and family Coccinellidae. Crop diseases cause major yield and quality losses and threaten wheat and barley production. This study evaluates the potential of Coccinella septempunctata and Coccinella undecimpunctata as biological control agents against aphids, the primary vectors of barley yellow dwarf virus. Greenhouse and laboratory experiments were conducted using barley and wheat seedlings infested with aphid species, while the beetles were reared under controlled conditions. Feeding rates were measured at different constant temperatures, revealing that aphid consumption increased with temperature and peaked at 27°C. C. undecimpunctata consistently consumed more aphids than C. septempunctata. These results support the use of these ladybird beetles as effective biological control agents that can reduce reliance on chemical pesticides and help control virus transmission in cereal crops.
