Effect of Pollen from Different Plant Species on Development of Typhlodromus pyri (Sheuten) (Acari: Phytoseiidae)

Typhlodromus pyri (Sheuten) (Acari: Phytoseiidae) is a phytoseiid mite with a high potential in controlling the false Chilean mite (Brevipalpus chilensis Baker; Acari: Tenuipalpidae). The purpose of this study was to determine the effect of different plant species pollen as a complementary food in t...

The purpose of this study was to determine the effect of different plant species pollen as a complementary food in the development of T. pyri when its prey is in low levels of availability.

Mean duration from egg to adult with H. incana was 8.70 ± 1.66 d, protonymph 3.27 ± 0.21 d, and deutonymph 2.90 ± 1.45 d (P > 0.05).
