| The predatory mite Neoseiulus barkeri Hughes (Acari: Phytoseiidae) is one of the native predator of the country. Different diets including different biological stages of three storage mite species Tyrophagus putrescentiae (Schrank), Tyrolichus casei (Oudemans), Rhizoglyphus robini Claparede (Astigmata: Acaridae) and different plant pollens (corn and date pollen) were used in rearing containers on wet sponge. Storage mites fed with wheat bran, yeast and corn pollen. The number of predatory mites counted one, two, three and four weeks later. The number of predatory mites in the first to fourth counts when feeding on R. robini (2.70, 2.80, 3.28 and 5.58 times), T. casei (2.12, 2.45, 2.5 and 1.1 times) and T. putrescentiae (2.79, 3.58, 4.90 and 5.70 times) were compared to the initial concentration placed in each container, respectively. Among the three prey species used, T. putrescentiae provided better food for the predatory mite. The number of predatory mites in the first to fourth counts when feeding on corn pollen (2.20, 3.10, 4.10 and 5.35 times) and date pollen (1.40, 3.10, 3.72 and 1.70 times) were compared to the initial concentration placed in each container, respectively. Corn pollen is the best option for predatory mites due to the presence of compounds that are more nutritious and the simplicity of its preparation. Thus, in the fourth count, the number of predatory mite reached 5.35 times when fed on corn pollen. In the rearing of this predator, T. putrescentiae recommended with wheat bran, yeast and corn pollen. |
