Figure 3 in Orientation of Hippodamia variegata (Coleoptera: Coccinellidae) to healthy and Beauveria bassiana-infected Aphis fabae (Hemiptera: Aphididae) in an olfactometer system

Figure 3. Response of Hippodamia variegata to broad bean plants infested by A. fabae infected by Beauveria bassiana at the interval of 24 h after infection versus broad bean plants infested by A. fabae infected by B. bassiana at intervals of 48 (a) and 72 (b) h after infection. The white bars indicate the numbers of insects choosing broad bean plants infested by A. fabae infected by B. bassiana at intervals 48 and 72 h after infection, whereas the black bars indicate the numbers of insects that chose broad bean plants infested by A. fabae infected by B. bassiana at the interval of 24 h after infection.
