Life table parameters and predation capacity of Typhlodromus bagdasarjani (Phytoseiidae) fed on Cenopalpous irani (Tenuipalpidae) reared on different apple cultivars

Abstract

The life table parameters and predation rate of Typhlodromus bagdasarjani Wainstein & Arutunjan (Phytoseiidae) fed on Cenopalpus irani Dosse (Tenuipalpidae) nymphs reared on four apple cultivars Kohanz Golab, Imperial Gala, Lebanon Red, and Granny Smith were determined under laboratory conditions. The longest developmental time of immature stages in females was observed on Kohanz Golab, and the shortest one was on Granny Smith. The fecundity ranged from 19.17 eggs/female on Golab Kohanz to 32.78 eggs/female on Granny Smith. The highest and lowest intrinsic rate of increase (r) were obtained on Granny Smith (0.251 day-1), and Kohanz Golab (0.113 day-1), respectively. The total prey consumption by all immature stages on Kohanz Golab, Imperial Gala, Lebanon Red, and Granny Smith was 42.90, 34.71, 31.83, and 24.53 prey, respectively. The total prey consumption by adult females was 543.76 prey on Kohanz Golab, 419.40 prey on Imperial Gala, 376.87 prey on Lebanon Red, and 276.76 prey on Granny Smith. Our results showed that predator performance was strongly affected by feeding on C. irani mites reared on different apple cultivars, and also a significant difference was seen in the hunting capacity of T. bagdasarjani on different apple cultivars.
