Functional response of the predatory mite Amblyseius swirskii (Acari: Phytoseiidae) to Eotetranychus frosti (Tetranychidae) and Cenopalpus irani (Tenuipalpidae)

Abstract: Eotetranychus frosti and Cenopalpus irani Dosse are pests of apple trees that are widely distributed in apple orchards in Iran. The functional responses and predation rates of Amblyseius swirskii, one of the most commonly utilized phytoseiid mites for biological control, on these two pests were evaluated at 25 ± 1 °C, with 16:8 h L: D, and a relative humidity of 60 ± 10 % on apple leaves. The results of predation rate experiments on the two prey species indicated that the predator consumed significantly more e… Show more

“…In general, type II functional responses seem to prevail in phytoseiids. It is recorded in several species, such as Euseius finlandicus and Amblyseius andersoni preying on Panonychus ulmi larvae and adult females (Koveos & Broufas, 2000), Euseius scutalis preying on T. urticae and Eutetranychus orientalis (Acari: Tetranychidae; Stathakis et al, 2021); Amblyseius swirskii preying on Eotetranychus frosti (Acari: Tetranychidae) and Cenopalpus irani (Acari: Tenuipalpidae) (Bazgir et al, 2020); Iphiseius degenerans preying on T. urticae and E. orientalis (Fantinou et al, 2012). However, it should be noted that predatory arthropods' feeding may be affected by plant species and/or cultivars characteristics for example via the impediment of their movement or indirectly via the quality of their prey (e.g., Cédola et al, 2001;Messina & Hanks, 1998;Merlin et al, 2022;Paspati et al, 2021), indicating that functional responses should be also evaluated in several environmental scenarios.…”

“…Bazgir, Jafari, Shakarami, and Bahirae ( 2015 ) reported, under laboratory conditions, a survival rate for C. irani immature stages of 30.00, 43.75, 66.25, 85.00, 65.00 and 51.25% at 15, 20, 25, 30, 32 and 33.5°C, respectively. The highest gross fecundity rate was 34.60 eggs/female at 30°C and the lowest was 18.50 eggs/female at 15°C.…”

“…Furthermore, it can indicate predators’ search efficiency and predation rates, and assessing predator behavior is a vital initial stage in identifying predators’ ability to control prey [ 30 ]. Previous researchers demonstrated the functional response of A. swirskii feeding on the tetranychids Tetranychus turkestani [ 31 ], Eotetranychus frosti [ 32 ], astigmatid Suidasia medanensis [ 33 ], and eriophyid Aculops lycopersici [ 34 ].…”
