Relationships between food substances, developmental success and reproduction in Typhlodromus transvaalensis (Acari: Phytoseiidae)
Acarologia 40 (2), 107-111
Abstract: The predacious mite, Typhlodromus transvaalensis (Nesbitt) completed its life cycle when fed on the eriophyid mites Eriophyes dioscoridis Soliman and Abou-Awad and Eriophyes olivi Zaher and Abou-Awad, eggs of the scale insect Parlatoria zizyphus (Lucas) and pollen of Ricinus communis (L.) in experimental conditions. The percentage of individuals attaining maturity was less than 20% when nymphs of the tetranychid mite, Tetranychus urticae Koch, were provided. The development was faster and reproduction was higher when T. transvaalensis fed on eriophyid mites. T. urticae was an unsuitable feeding and reproduction substrate. The daily reproduction was as low as 0.4 and 0.8 eggs/ female/ day when females were maintained on pollen grains of R. communis and eggs of P. zizyphus. The adult female daily consumed 126, 97 and 6 individuals of E. olivi, E. dioscoridis and T. urticae, respectively.
