Olfactory responses of Neoseiulus cucumeris (Acari: Phytoseiidae) to odors of host plants and Frankliniella occidentalis (Thysanoptera: Thripidae)-plant complexes
Arthropod-Plant Interactions 5 (4), 307-314
Abstract: We studied the olfactory responses of Neoseiulus cucumeris (Acari: Phytoseiidae) to odors from eggplant (Solanum melongena L.), pepper (Capsicum aunuum), and tomato (Solanum lycopersicum), three host plants, and their complexes with different treatments (undamaged, mechanically damaged, infested, pre-infested) in an olfactometer. The results showed that N. cucumeris preferred the odors of undamaged eggplant, pepper, and tomato to clean air. N. cucumeris preferred the volatiles from eggplant infested with Frankliniella occidentalis (Thysanoptera: Thripidae) over undamaged, mechanically damaged, and pre-infested with F. occidentalis eggplant volatiles. The same results were observed with pepper and tomato. N. cucumeris adults preferred the odors of undamaged eggplant and tomato to undamaged pepper. Similarly, same results were observed with mechanically damaged eggplant, pepper, tomato, and same plants pre-infested with F. occidentalis. Compared with odors of tomato infested with F. occidentalis, N. cucumeris adults significantly responded to odors of eggplant and pepper infested with F. occidentalis. There was no significant difference of N. cucumeris in making choice between eggplant infested with F. occidentalis and pepper infested with F. occidentalis.
