Abstract
In the study on Coccinella septempunctata, the predator’s antennal sensitivity to six synthetic compounds was investigated using electroantennogram techniques. These compounds were selected based their biological activities. The results revealed that (-)-trans-caryophyllene, citronellal, and citronellol were the most attractive compounds to the predator whereas methyl salicylate, cis-3-hexenyl acetate, and (R)-(+)-limonene were the least attractive compounds. These findings hold potential for manipulating the behavior of C. septempunctata by using these attractive compounds to enhance its effectiveness as a biological pest control agent. Such manipulation could contribute to more sustainable agricultural practices by reducing reliance on chemical pesticides. The study underscores how understanding insect sensory perception can lead to innovative pest management strategies. Overall, this research sheds light on specific synthetic compounds that can attract Coccinella septempunctata, offering insights into potential applications for enhancing biological pest control methods and improving crop management practices. These findings have implications not only for pest management but also for broader agricultural sustainability efforts.
