Background
The two-spotted spider mite,
Tetranychus urticae
Koch (Acari: Tetranychidae), is a major pest of strawberry. It was necessary to control this mite pest that can reducing the quality and quantity of the fruits. In this regard, the effect of ZORO acaricide,
Neoseiulus californicus
(McGregor) and
Amblyseius swirskii
Athias-Henriot for suppressing the naturally occurring
T. urticae
populations on three strawberry cultivars were investigated.
Results
The two predatory mites and ZORO treatments significantly suppressed the populations of
T. urticae
below the control in all tested cultivars. In most cases of the current study, significantly lower numbers of
T. urticae
were generally observed in ZORO and
N. californicus
treatments compared to
A. swirskii
treatment. In all cultivars, the overall mean of reduction percentages of
T. urticae
populations in
N. californicus
and ZORO treatments were not statistically different, and all were significantly higher than that in
A. swirskii
treatment.
Conclusion
The present results suggested that the release of
N. californicus
and the application of ZORO acaricide could be promising strategies for controlling
T. urticae
on strawberry, although the release of
N. californicus
appears to be more competent tactic than ZORO acaricide.
