Biological control of broad mites (Polyphagotarsonemus latus) with the generalist predator Amblyseius swirskii.

van Maanen R, Vila E, Sabelis MW, Janssen A - Exp. Appl. Acarol. (2010)

Bottom Line: Several phytoseiid mites have been described to control these mites.The oviposition rate of A. swirskii on a diet of broad mites was lower than on a diet of pollen, but higher than oviposition in the absence of food.Population-dynamical experiments with A. swirskii on single sweet pepper plants in a greenhouse compartment showed successful control of broad mites.

ABSTRACT
The broad mite is a serious pest of a variety of crops worldwide. Several phytoseiid mites have been described to control these mites. However, broad mites are still one of the major pest problems on greenhouse pepper in South-eastern Spain. The generalist predatory mite A. swirskii is widely used against other pests of pepper plants such as thrips and whiteflies, the latter being a vector of broad mites. We assessed the potential of A. swirskii to control broad mites. The oviposition rate of A. swirskii on a diet of broad mites was lower than on a diet of pollen, but higher than oviposition in the absence of food. Population-dynamical experiments with A. swirskii on single sweet pepper plants in a greenhouse compartment showed successful control of broad mites.

Average oviposition rate of young adult Amblyseius swirskii on a diet of broad mites, pollen or without food. Shown are average numbers of eggs (+SEM) per female per day measured from 24 to 48 h since the predators were put on the diet or kept without food. Different letters indicate significant differences among treatments

Fig1: Average oviposition rate of young adult Amblyseius swirskii on a diet of broad mites, pollen or without food. Shown are average numbers of eggs (+SEM) per female per day measured from 24 to 48 h since the predators were put on the diet or kept without food. Different letters indicate significant differences among treatments

Mentions: Oviposition was significantly different among treatments (Fig. 1, KW = 44.4, df = 2, P < 0.0001). The oviposition rate of A. swirskii on a diet of broad mites was lower than the oviposition rate on a diet of pollen (difference in average rank = 14.9, P < 0.05), but higher than oviposition in the absence of food (difference in average rank = 36.9, P < 0.0005, Fig. 1). The predators consumed on average 8.6 (SE = 0.80) adult female broad mites per female during the first day and 10.2 (SE = 0.70) during the second day.Fig. 1
