Life history parameters of Tetranychus cinnabarinus on glasshouse plants¹

Abstract

During the last few years, mass outbreaks of Tetranychus cinnabarinus have occurred on different host plants in Poland. The most heavy damage has been noted on glasshouse tomatoes, but the species was frequent on other host plants such as cucumber, capsicum, aubergine and gerbera. The aim of the study was to estimate the potential of development of T. cinnabarinus on different host plants. Demographic parameters such as intrinsic rate of natural increase, net reproductive rate, and the mean generation time, have been used as criteria of life‐history traits on glasshouse tomato, cucumber, capsicum and gerbera. The relationships between the difference in life‐history parameters of T. cinnabarinus and the different degree of damage on these host plants are discussed.

Tomato Carrying MI-1.2 Gene as a Host-Plant to the Two-Spotted Spider Mite (Tetranychus urticae Koch): Results of Laboratory Evaluation

“…High values of r m obtained for T. urticae on tested plants in this study are comparable or even higher to those on bean, cucumber, gerbera and cultivated already cultivars of tomato plants (Witul 1992, Witul & Kielkiewicz 1996, 1999. The value of total fecundity and egg to egg developmental time of T. urticae on Motelle plants are close to the values of parameters reported earlier for the carmine spider mite (T. cinnabarinus) known as mite species with higher reproductive potential than T. urticae on commercially available tomato plants (Kielkiewicz 1996a,b, Witul & Kielkiewicz 1999.…”
